Overview
Description:
We are looking for an expert Solidity dev to model and build an ERC-7540-style vault from our specifications. You’ll design the logic, model the contract, and ultimately deliver clean, production-ready code.
1-2 months of work.
What you’ll do:
• Model vault interactions (deposits, withdrawals, accounting).
• Write efficient Solidity contracts (ERC-7540 compliant).
• Run invariant and fuzz tests (Foundry preferred).
• Document architecture and testing assumptions.
What we’re looking for:
• Deep DeFi experience (vaults, AMMs, lending, yield).
• Mastery of Solidity + EVM internals.
• Strong background in fuzz/invariant testing and contract modelling.
• Proven on-chain deployments or audit-level work.
Nice to have:
• Foundry wizardry, gas optimisation chops, open-source DeFi repos.
