You'll own the on-chain layer of Abba Baba — designing and auditing the AbbababaEscrowV2 contract, building the settlement logic that processes thousands of A2A transactions, and ensuring the cryptographic guarantees that make trustless agent commerce possible. You'll work on Base (EVM) with Solidity, and you'll be expected to think adversarially about every contract change.

Requirements

  • Solidity
  • Foundry / Hardhat
  • EVM internals
  • Base / Ethereum
  • USDC / ERC-20
  • security auditing
  • formal verification

Responsibilities

  • Design and implement smart contract upgrades for the AbbababaEscrowV2 settlement system
  • Conduct internal security reviews before every contract deployment
  • Write comprehensive test suites (unit, integration, fuzzing) for all contract logic
  • Coordinate external audits and respond to findings with documented remediations
  • Monitor on-chain contract health — dispute rates, gas costs, revert patterns
  • Research and evaluate new EVM primitives and token standards for platform use
