DApp developer Antfarm

Job description

About the role

A DApp lives or dies on what happens when a transaction goes wrong. That's where we want your attention.

You'd build the interfaces between users and our contracts: wallet connection, signing, and the status and error states around every on-chain action. A rejected transaction, the wrong network, a contract that isn't deployed yet, a call that's guaranteed to revert and should have been caught before the user paid gas, all of that is the actual job, not an edge case to hand-wave.

Expect React and TypeScript with viem or wagmi, plus a healthy instinct for which values should never be trusted from the client. If you've shipped a production DApp and carry a few scars from transaction UX, we'd like to talk.

Responsibilities

Build decentralized application interfaces that connect wallets and call smart contracts

Implement mint, sign, approve, and transaction flows with clear status and error states

Handle failure modes: rejected transactions, wrong network, undeployed contracts, and reverts

Read onchain state to validate actions before users pay gas

Integrate contract reads and writes using viem, wagmi, or ethers.js

Collaborate with contract engineers on integration and trust boundaries

Required skills

4+ years of frontend development experience, including production DApps

Strong TypeScript and React skills with EVM wallet integration experience

Deep understanding of transaction lifecycles, gas, and common failure modes

Judgment about client-side trust and onchain verification

Attention to transaction UX and error handling

Preferred skills

Experience with account abstraction, WalletConnect, or multi-chain apps

Familiarity with EAS, signatures, or verifiable credentials

Contributions to open-source Web3 tooling
