About this role
PHP, Adobe Flash, Software Architecture, ActionScript, Blockchain, Ethereum, Solidity, Smart Contracts · I am building a DeFi module that combines instant, uncollateralised flash loans with a collateral-backed lending layer. The goal is to let users tap deep on-chain liquidity, route it through our own logic, then close the loan or roll it into a standard collateralised position— all within a single, gas-efficient flow.
Scope of work • Design and code Solidity smart contracts that request, receive and repay flash liquidity, then optionally transfer the resulting position into a collateral vault. • Wire the contracts to the leading liquidity pools on the chosen EVM chain(s); I am open to Ethereum mainnet, BSC, Polygon or any network you feel offers the best mix of liquidity and fees. • Expose clean external methods so a front-end or script can trigger: – initiateFlashLoan(amount, asset, params) – repayOrConvert(txData) – withdrawCollateral(positionId) • Provide Hardhat tests that cover happy-path and failure scenarios, including re-entrancy checks and interest or fee accounting. • Supply a minimal React or Node script to demonstrate end-to-end usage.
Acceptance criteria 1. A full flash-loan cycle (borrow → execute arbitrary operation → repay) succeeds in a sin
