The Web3 Developer resume skills and keywords that matter in 2026
Web3 Developer screens on the dApp and wallet-UX side of the stack
Web3 Developer is the dApp and front-end engineer in the Blockchain / Web3 family. You ship the
Next.js or React app that the wallet pops up in front of (RainbowKit, ConnectKit, Privy, Reown
with WalletConnect AppKit), you call every external function on the deployed contracts through a
client library (viem and wagmi on the modern plane, ethers.js v6 on most active codebases,
web3.js on the legacy plane), you wire the wallet flow end to end (signing, network switching,
revert handling, transaction toast UI), you ship the account abstraction layer that hides the
seed phrase from a real user (ERC-4337 bundlers and paymasters with Pimlico or Biconomy, Safe
for treasury, session keys for one-tap gameplay, sponsored gas for onboarding), you wire the
login that proves a wallet owner without a password (SIWE, EAS attestations, ENS resolution,
lit-protocol for token-gated content), you read the chain through an indexer (The Graph,
Goldsky, Alchemy SDK, Subsquid, Dune materialized views) because polling the RPC for every read
kills the UX, and you ship the metadata to a storage layer that does not vanish (IPFS through
Pinata or Web3.Storage, Arweave, Filecoin, EIP-4844 blobs for the rollup-aware lanes). You write
more TypeScript and React than Solidity, but you read the contracts every day and write the
occasional helper (a paymaster wrapper, a session key validator, a small ERC-721 mint flow). The
seat sits next to Blockchain Developer on one side (broader stack, deeper protocol code), Smart
Contract Developer on the other (deepest Solidity authoring), and across the room from Front-End
Engineer (no chain code at all). The week looks like a wagmi hook on Monday, an ERC-4337
paymaster wire-up on Tuesday, a SIWE login flow on Wednesday, a Graph subgraph read on Thursday,
and a Next.js deploy with IPFS metadata on Friday. ATS engines score on skills and
keywords, and hiring managers on the other side keep filtering for the same compact
set: Next.js, React, viem, wagmi, ethers, RainbowKit, ERC-4337, SIWE, The Graph, IPFS, account
abstraction, session keys, and monthly active wallet or first-transaction completion numbers
from real product. What stays unclear is which signals carry the most weight right now, where
2026 shifted things (viem and wagmi overtaking ethers on most modern dApps, ERC-4337 with
Pimlico landing as the consumer-app default, session keys and sponsored gas pulling first-tx
completion above 70 percent, SIWE replacing email and password on every wallet-native app,
Reown with WalletConnect AppKit pulling share from RainbowKit on multi-wallet shops), and how
to phrase the dApp work you actually shipped so both the recruiter and the parser register
it.
This page is the cheat sheet
What follows is the ranked rundown of Web3 Developer hard skills, soft skills, and ATS keywords
a Senior file wants in 2026, sliced by category and by seniority band, written the way I would
put it on the page after a long stretch reading Coinbase, Uniswap Labs, Reservoir, Zora,
Manifold, OpenSea, Privy, Pimlico, Biconomy, Safe, RainbowKit, Reown, and consumer-crypto
startup Web3 Developer resumes. If you want an editable starter that routes these keywords into
the right slots already, grab the
Web3 Developer resume template.
Web3 Developer resume keywords & skills at a glance
The fast answer, two ways
Most of this page is the deep read on how Web3 Developer skills get weighted. When the form is
already open and the deadline is tonight, jump to one of the two tools below: the
industry-standard Web3 Developer keyword shortlist (the safe pick when no specific JD is in hand),
or the scanner that lifts the keywords straight out of whichever Web3 Developer posting you happen
to be staring at.

Extract Web3 Developer resume keywords from a JD
Drop a Web3 Developer, dApp Engineer, or Front-End Web3 Engineer
posting into the box. The scanner picks out the dApp frameworks, EVM client libraries, wallet
stacks, account abstraction tools, auth flows, indexers, storage layers, and production dApp
engineering tools worth carrying into your Skills row and bullets, sorted by tier. Runs locally
inside this tab; the JD text never leaves your machine.
Web3 Developer: Hard Skills
8 categories to include in your resume's Technical Skills section
Stars flag the must-haves. The closing line on each card drops straight into the matching row of your
Skills section, no reshaping needed.
dApp Frameworks
The floor every Web3 Developer file rests on. Next.js and React carry the
must-have row on modern dApps; RainbowKit and ConnectKit cover the wallet-connect plane; Privy
and Reown with WalletConnect AppKit close the row on multi-wallet consumer-crypto JDs.
Next.js, React, Vite, RainbowKit, ConnectKit, Privy, Reown with

EVM Client Libraries
The plane Coinbase, Uniswap Labs, and consumer-crypto Web3 Developer
screens cut on. viem and wagmi carry the must-have row on modern dApps; ethers.js v6 covers
most active codebases; web3.js close the row on legacy contract integrations.
viem, wagmi, TanStack Query, ethers.js v6, web3.js as legacy, ABI

Wallet & Account Abstraction
The signal that splits a Web3 Developer from a generic Front-End Engineer.
ERC-4337 carries the must-have row on consumer dApps; Pimlico and Biconomy cover the bundler and
paymaster plane; Safe, session keys, and sponsored gas close the row at the Senior band.

Auth & Identity
The row Coinbase, Reservoir, and consumer-crypto Web3 Developer screens
read first. Sign-In with Ethereum carries the must-have row on wallet-native auth; ENS
resolution covers the human-readable plane; EAS attestations and lit-protocol token-gating
close the row on social and gated-content JDs.

Polling the RPC for every read kills the UX. The Graph carries the must-have row on subgraphs;
Goldsky covers the managed plane; Alchemy SDK, Subsquid, and Dune materialized views close the
row at the high-throughput band.
The plane NFT studios, social-graph teams, and consumer-app Web3
Developer screens read first. IPFS through Pinata or Web3.Storage carries the must-have row;
Arweave covers the permanent-storage plane; Filecoin and EIP-4844 blobs close the row on
rollup-aware and high-volume JDs.

On-Chain Game / NFT Surfaces
The signal that splits Web3 Developer from a generic dApp Engineer.
ERC-721 and ERC-1155 carry the must-have row on NFT and game surfaces; Manifold and Zora cover
the mint and royalty plane; Reservoir closes the row on cross-marketplace and trading JDs.
The plane Coinbase, Reservoir, and consumer-crypto Web3 Developer screens
read first when comparing two strong files. Vercel deploys carry the must-have row on shipping
cadence; RPC fallback transports cover the reliability plane; Sentry error tracking and
on-chain analytics close the row at the Senior band.
Dropping "great communicator" into a Skills row never won a Web3 Developer screen. The signal
that lands here sits inside bullets that name the wallet flow, the chain, the ship event, and the
outcome metric. Five rows below, one bullet template per row, ready to adapt to the actual
product and the actual numbers.
Wallet-UX empathy
Senior Web3 Developer hiring leans on whether you can put a new user
through the wallet flow without losing them at signing. The signal here is a moment you cut
the signing prompts, hid the seed phrase with account abstraction, or shipped a one-tap
session-key flow that lifted first-transaction completion above 70 percent.
How to show it
Cut the v2 mint flow from
3 signing prompts to 1 with ERC-4337 session keys via
Pimlico; lifted first-tx completion from 38 to 71 percent, cut
median time-to-first-tx from 3.2 minutes to 28 seconds.
Written communication for protocol and UX trade-offs
Most of your stakeholders are protocol engineers, design, product, and
the team that owns the contracts. Senior Web3 Developer files show you can write a 400-word
spec on why a sponsored gas approach beats a meta-transaction approach for the same flow,
hold the design review without losing the room, and post the rollout doc the week the flow
ships.
How to show it
Wrote the v3 onboarding trade-off doc picking
ERC-4337 sponsored gas via Pimlico over a meta-transaction relay; ran
2 design reviews, shipped the rollout to 62 percent of new
sessions in 30 days with zero abuse incidents.
Security paranoia on the signing side
Senior Web3 Developer files treat every signature as money on the line.
The signal here is a moment you caught a phishing-friendly typed-data prompt, a session-key
scope that was too broad, or a paymaster path that opened a sponsored-gas drain, and shipped
the tightening before a user paid for it.
How to show it
Caught a broad session-key scope in the v2 game
flow two days before launch; tightened the session policy to a single contract
and a 30-minute expiry, added a Pimlico abuse alert, shipped the fix before any
user signed it, zero incidents in 6 months.
Judgment on chain choice
A Web3 Developer file that ships every dApp to mainnet with no
opinion loses the seat. The signal here is naming the moment you picked Base over Arbitrum
for a consumer flow (lower fees, Coinbase wallet default), or Polygon over Optimism for a
high-volume NFT mint (gas headroom for the drop), and explained the trade-off in the launch
doc.
How to show it
Picked Base over Arbitrum for the v2 consumer
mint; wrote the chain selection memo citing 61 percent lower
median fees and the Coinbase wallet default, shipped the drop on Base, sold
4,200 of 5,000 NFTs in 24 hours.
Open-source empathy
The signal that splits a Senior Web3 Developer from one who only ships
inside the company repo. Quote a moment you filed a PR to viem, wagmi, RainbowKit, or
Privy, contributed a fix back upstream, and saved your team from carrying a fork the next
time the library shipped a major.
How to show it
Filed 3 PRs to wagmi and viem over two quarters
(ERC-4337 connector fix, EIP-712 typed-data helper, ENS reverse-resolution cache); merged
on the next minor release, retired the in-house fork, freed
1.5 days a quarter of upgrade work for the dApp team.
ATS keywords
How ATS read your resume keywords
What ATS engines do with a Web3 Developer resume, how to lift the right dApp frameworks, EVM
client libraries, wallet stacks, account abstraction tools, auth flows, indexers, storage layers,
and production dApp engineering tools out of any Web3 Developer JD, and the 25 keywords every
Web3 Developer resume should carry in 2026.
01
What ATS actually does
The current ATS stack (Workday, Greenhouse, iCIMS, Lever,
SmartRecruiters) reads your resume into structured fields and ranks every candidate against a
keyword set the recruiter or dApp hiring manager set on the req. Nobody is auto-rejected by a
machine; you sort lower on a ranked list. For a Web3 Developer pipeline that screens hard on
Next.js, React, viem, wagmi, RainbowKit, ERC-4337, SIWE, The Graph, IPFS, and account
abstraction, a lower sort is the same as never being seen.
02
Why position matters
Plenty of ATS engines score where a keyword appears, not just how
often. The same tool name weighs more in the resume title, the Profile Summary, and the
Technical Skills row than it does buried in a hobbies footer. For Web3 Developer JDs, the
priority tokens (Next.js, React, viem, wagmi, ethers, RainbowKit, ERC-4337, SIWE, The Graph,
IPFS, Privy, Pimlico) belong in the top third of page one, not down in a closing block.
03
Repetition vs. stuffing
Naming wagmi in the Skills row plus the same word inside two or
three shipped dApp bullets is exactly the pattern parsers expect. Pasting it twelve times in
a hidden white-text footer is stuffing and current parsers catch it. The healthy band is
2 to 5 honest occurrences per priority keyword.
Mining your target JD
A 3-step keyword extraction loop
STEP 01
Pull six Web3 Developer postings
Grab six Web3 Developer, dApp Engineer, or Front-End Web3 Engineer
postings at the company tier you are chasing next (Coinbase, Uniswap Labs, Reservoir, Zora,
Manifold, OpenSea, Privy, Pimlico, Biconomy, Safe, RainbowKit, Reown, consumer-crypto
startup, NFT studio). Drop them into one document so the recurring dApp framework, client
library, wallet stack, account abstraction tool, auth flow, indexer, storage, and analytics
tokens jump out side by side.
STEP 02
Cluster the dApp nouns
Mark every dApp framework, EVM client library, wallet stack, account
abstraction tool, auth flow, indexer, storage layer, and dApp analytics tool that recurs in
four or more of the six JDs. That cluster is your priority set. Anything that shows up in
only one posting drops to the secondary "include if true" list.
STEP 03
Reconcile against your resume
Every priority noun should sit in your Skills block AND in at least
one shipped dApp, wallet flow, account abstraction rollout, indexer read, or storage
integration bullet. Gaps are either truthful additions (drop them in where they really
belong) or a sign the posting is wrong for your current Web3 Developer band.

account abstraction tool, auth flow, indexer, and storage terms the parser is missing, which
bullets read like a generic front-end file, and where the dApp story falls short of the
Senior Web3 Developer band.

What Junior, Mid, Senior, and Staff Web3 Developers are expected to list
The vocabulary stays roughly steady up the Web3 Developer ladder; what shifts is the dApp
surface you own, the wallet flows you ship, the account abstraction rollouts you drive, the
indexers and storage layers you steward, and how much your code moves monthly active wallets,
first-transaction completion, and sponsored gas numbers. Web3 Developer has more Mid and Senior
openings than Junior; consumer-crypto startups and NFT studios run the small Junior pipelines,
while protocol and infra shops keep the entry bar at Mid.
L1 · ENTRY
Junior Web3 Developer
0 to 2 years. Fewer Junior seats than for a generic Front-End role.
The common path in is a Front-End Engineer who shipped a side dApp on Sepolia with wagmi, a
Full-Stack Developer who picked up RainbowKit and SIWE on a hack project, or a Blockchain
Developer who crossed into product code. At this band, expect to ship wagmi hooks under
review, wire RainbowKit and SIWE on small flows, file PRs on the dApp test suite, and own a
small slice of the wallet UX with a Senior in the room.
2 to 5 years. Own a slice of the dApp (the wallet flow, the mint
page, the staking dashboard, or the indexed feed), ship 3 to 5 production flows with viem and
wagmi, wire ERC-4337 with Pimlico or Biconomy on at least one consumer surface, run SIWE for
auth, ship indexed reads via The Graph or Alchemy SDK, file PRs on wagmi or RainbowKit, and
own one storage integration on IPFS.
5 to 9 years. Own a dApp surface end to end, steward the wallet UX
decisions, drive the account abstraction rollout with Pimlico and Biconomy, own the SIWE and
session-key strategy, run the indexer pattern across the product, ship the Reown or RainbowKit
multi-wallet setup, and carry monthly active wallets, first-transaction completion, and
sponsored gas volume as the headline metrics.
9+ years. Set the dApp pattern across the product line, steward the
account abstraction architecture, own the wallet UX forecast with the Head of Product and the
CTO, run hiring loops, partner with protocol and design on the roadmap, and carry org-level
monthly active wallets, sponsored gas spend, and dApp uptime as headline metrics. At this band
the Skills row stops telling the story; published dApp patterns, ERC-4337 deployments, MAW
growth, and practice-wide influence carry it instead. A recognised public footprint (a PR
merged into wagmi or viem, an ERC-4337 helper library shipped on GitHub, a conference talk at
Devcon or ETHDenver) reads as the standard spread.
One Technical Skills block, 6 to 7 labeled rows, sitting directly beneath the Profile Summary.
Each token surfaces again as proof inside the shipped dApp, wallet flow, account abstraction,
indexer, and storage bullets underneath.
01
Placement
Set it right after the Profile Summary, before Work Experience,
with your GitHub, a link to a shipped dApp, and a portfolio link in the header next to
LinkedIn. Web3 Developer recruiters read top down, and parsers (Workday, Greenhouse, iCIMS,
Lever, SmartRecruiters) lift dApp tokens more reliably when the block sits in a clearly
labeled slot on the first half of page one.
02
Format
Use labeled rows, not a comma-soup paragraph. Pick 6 or 7 row
labels (dApp Frameworks, EVM Client Libraries, Wallet & AA, Auth & Identity, Indexed
Reads, Storage, dApp Engineering). Hold each row to one wrap-friendly line of 5 to 9 nouns,
and skip nested bullets inside the Skills block.
03
How many to include
30 to 40 specific dApp frameworks, EVM client libraries, wallet
stacks, account abstraction tools, auth flows, indexers, storage layers, and production dApp
tools in total. Under 24 reads thin for any Web3 Developer seat above Mid; over 48 reads
like a feature dump. Every entry should be a real tool, framework, or metric, never a
feeling word.
04
Weaving into bullets
Tie every bullet to the dApp surface, the wallet flow, the
ship event, and the outcome metric. The version that clears the recruiter scan and the ATS
sort reads like this:
Weak
Built dApp front-end and improved wallet UX.
Strong
Shipped the v2 mint flow on Base in
Next.js with wagmi and viem; wired ERC-4337 with Pimlico
sponsored gas, lifted first-tx completion from 38 to 71 percent,
pushed monthly active wallets from 4,200 to 17,800 inside two
quarters.
Same scope, but the second line carries six recruiter
signals (framework, client library, chain, AA infra, conversion outcome, MAW growth) and
reads at the Senior band.
Quality checks
Use the casing the docs use. "Next.js" with the dot, "React" capitalized, "viem"
lowercase, "wagmi" lowercase, "ethers.js" lowercase with the dot, "RainbowKit" mixed-case,
"ConnectKit" mixed-case, "Privy" capitalized, "Reown" capitalized, "WalletConnect"
mixed-case, "ERC-4337" with the hyphen and digits, "SIWE" all caps, "The Graph" with
capital T, "Pimlico" capitalized, "Biconomy" capitalized, "Safe" capitalized, "IPFS" all
caps, "Pinata" capitalized, "Alchemy SDK" mixed-case.
Drop proficiency stickers ("Expert in wagmi") and skip the star ratings. The screen
cannot verify them, and the entries around them lose credibility by association.
Group by purpose (dApp Frameworks, EVM Client Libraries, Wallet & AA, Auth &
Identity, Indexed Reads, Storage, dApp Engineering), not by alphabet. Web3 Developer
recruiters scan by category.
Every priority tool or metric in the Skills row needs at least one bullet showing it
inside a real dApp, wallet flow, account abstraction rollout, indexer read, or storage
integration. The row signals familiarity; the bullet proves you shipped with it.
Skills in action
Five shipped bullets, with the Web3 Developer keywords wired in
A Web3 Developer bullet has to do three jobs at once: name the dApp surface and chain, name the
wallet flow and ship event, and name the outcome metric it pushed. The chips under each line
spell out the tokens a recruiter and the ATS parser will register.

Pitfalls
Six common mistakes on Web3 Developer resumes
These turn up week after week on the Web3 Developer reviews I run. Each is a quick rewrite once
you catch the pattern.
No wallet-UX metrics
A file that says "improved wallet UX" without ever quoting monthly
active wallets, first-transaction completion, signing-prompt counts, or returning-wallet rate
reads as someone who never measured the work. Web3 Developer pipelines filter hard on at least
one quantified UX outcome per shipped flow.
Fix: Put a MAW, first-tx, or sign-in metric on every
wallet bullet. "Lifted first-tx completion from 38 to 71 percent with ERC-4337 sponsored gas"
closes the gap.
Missing account abstraction or session-key signal
A Senior Web3 Developer file in 2026 with no ERC-4337, no Pimlico
or Biconomy bundler, no session-key rollout, and no sponsored-gas number reads as someone who
shipped before the AA wave. Most consumer-app JDs filter on at least one AA signal at the Mid
band and on a rollout outcome at the Senior band.
Fix: Surface one ERC-4337 line on at least one
Senior role. "Rolled out ERC-4337 with Biconomy, hit 62 percent AA adoption on new sessions in
30 days" closes the gap.
Indexer work buried under "I called the contract"
A file that says "read on-chain data" without ever naming The Graph,
Goldsky, Alchemy SDK, or Subsquid reads as someone polling the RPC for every render. Senior
Web3 Developer JDs filter on indexed reads because that is what holds the UX above one second.
Fix: Surface the indexer on at least one dashboard
bullet. "Wired The Graph and Alchemy SDK for the portfolio dashboard, cut median load from
2.4s to 380ms" closes the gap.
Solidity-heavy on a front-end-leaning role
A Web3 Developer file that leads with Foundry invariants, Slither
runs, and gas optimisation reads as a Blockchain Developer or Smart Contract Developer
reaching for a dApp title. The recruiter scans the first few bullets for Next.js, wagmi, and
wallet UX; if those are missing, the file gets routed to the contract-side pipeline instead.
Fix: Lead with the dApp surface (Next.js, wagmi or
viem, RainbowKit, ERC-4337, SIWE) and save Foundry, Slither, and gas optimisation for the
Blockchain Developer file or for a single supporting bullet.
No reliability or production signal
A Senior Web3 Developer file with shipped dApps and no RPC fallback,
no Sentry error tracking, no on-chain analytics, and no uptime number reads as someone who
shipped a hack-night demo. Most consumer-crypto JDs filter on at least one production
reliability signal at the Senior band.
Fix: Surface one reliability line on at least one
Senior role. "Cut RPC failure rate from 1.8 to 0.2 percent with viem multi-provider
transports" closes the gap.
Confusing Web3 Developer with Blockchain Developer, Smart Contract Developer, or Front-End Engineer
A file that leads with Solidity authoring and audit prep reads as a
Smart Contract Developer. A file that leads with the broad on and off-chain stack reads as a
Blockchain Developer. A file that leads with React and Tailwind with no wallet code reads as
a Front-End Engineer. Web3 Developer sits in a different lane: the dApp surface (Next.js with
wagmi and viem, RainbowKit, ERC-4337, SIWE, indexed reads, IPFS).
Fix: Lead with the dApp-plus-wallet-plus-AA combo
(a shipped flow tied to a named chain tied to a real wallet stack tied to a MAW or first-tx
metric) and save deep contract code for the Blockchain Developer or Smart Contract Developer
files.

Free, line-by-line feedback within 12 hours, by a former Google recruiter.
Aim for 30 to 40 specific dApp frameworks, EVM client libraries, wallet stacks, account
abstraction tools, auth flows, indexers, storage layers, and production dApp engineering
tools grouped into 6 or 7 labeled rows. Under 24 reads thin for any Web3 Developer seat
above Mid; over 48 reads like a feature dump. Every line in the Skills row should
resurface inside at least one shipped dApp, wallet flow, account abstraction rollout,
indexer read, or storage integration bullet.
Next.js, React, viem, wagmi, ethers, RainbowKit, ERC-4337, SIWE, The Graph, IPFS, and
account abstraction are the non-negotiables. Privy, Pimlico, Biconomy, Safe, session keys,
sponsored gas, EAS attestations, ENS resolution, and Alchemy SDK split Senior and Staff
files.
Web3 Developer (this page) is the dApp and front-end engineer for crypto product: Next.js
or React apps wired to EVM with viem and wagmi, wallet UX with RainbowKit or Privy,
account abstraction with ERC-4337 and session keys, SIWE login, IPFS storage, and indexed
reads through The Graph or Alchemy SDK. Blockchain Developer sits broader (the full on
and off-chain stack, deeper protocol side). Smart Contract Developer sits deepest on
Solidity, Vyper, and Move authoring with audit prep as the headline skill. Front-End
Engineer has no chain code at all. Full-Stack Developer has no chain code at all either.
If your week is a wagmi hook on Monday, an ERC-4337 paymaster wire-up on Tuesday, a SIWE
login flow on Wednesday, a Graph subgraph read on Thursday, and a Next.js deploy with
IPFS metadata on Friday, you are on the right page.
Some, but not a lot. Most Web3 Developer postings expect you to read Solidity
comfortably, call any function on a deployed contract through viem or wagmi, and ship the
occasional small helper contract (a paymaster wrapper, a session key validator, a small
ERC-721 mint contract). What separates the role from a Smart Contract Developer is that
the bulk of your week is TypeScript, React, and wallet UX, not Solidity authoring. A Web3
Developer file that leads with Foundry invariants and gas optimisation reads as a
Blockchain Developer reaching for a front-end title.
Quote the monthly active wallets you hit (lifted MAW from 4,200 to 17,800 inside two
quarters), the transaction conversion rate you moved (lifted first-tx completion from 38
to 71 percent), the account abstraction adoption (rolled out ERC-4337 to 62 percent of
new sessions in 30 days), the gas you sponsored (pushed 12k USD a month of sponsored gas
through Pimlico with zero abuse), and the RPC failure rate you cut (cut RPC failures
from 1.8 to 0.2 percent with viem fallback transports). A line like "Shipped ERC-4337
with RainbowKit and Privy, lifted first-tx completion from 38 to 71 percent" reads at the
Senior band.
Some, but fewer than for a generic Front-End role. Most Web3 Developer postings open at
Mid because the wallet UX, signature, and account abstraction surface is small but
unforgiving (one bad signing pattern moves real funds). The common paths in are a
Front-End Engineer who shipped a side dApp on Sepolia with wagmi, a Full-Stack Developer
who picked up RainbowKit and SIWE on a hack project, or a Blockchain Developer who
crossed into product code. Junior seats turn up at consumer-crypto startups and at NFT
studios more often than at protocol shops, so target both lists when you are starting
out. Run the file through an ATS
Checker to confirm the parse.
Read them, yes. Author them top to bottom, not usually. A Senior Web3 Developer is
expected to read any ERC-20, ERC-721, ERC-1155, or ERC-4337 contract, decode events
through viem or the Alchemy SDK, write the wagmi hooks that call every external function,
ship the wallet flow that signs the transaction, and handle every revert path in the UI.
The deeper contract authoring (vault logic, AMM math, governance, audit prep) sits with
the Smart Contract Developer or the Blockchain Developer on the team. A Web3 Developer
file that lists Foundry invariants and Trail of Bits findings is on the wrong page.
Tier labels and frequency bars come from a sample of roughly 150 US Web3 Developer postings I read
on LinkedIn, Indeed, and direct company career pages in Q1 and Q2 of 2026. Numbers shift each
quarter; check your own target JDs before leaning on any single keyword.
