Solidity/MEV specialist
Hello! We are looking for a Solidity/MEV specialist to finalize our execution stack.
Context
We already have an on-chain "squeeze radar" (node + detector) working.
We need fast/private execution (private bundles) and/or integration with existing executors.
The main bottleneck: the executor contract — our developer made the mechanics, but the contract is not performing.
Goal
When the radar catches an event (dump/squeeze under conditions), we want to execute trades quickly and privately:
Buy (and optionally subsequent actions: approve)
Priority: speed, stability, security.
What needs to be done
Solidity contract "Executor" (minimal, gas-optimized)
Swap functions through popular routers:
Uniswap V2-like (swapExactETHForTokens / swapExactTokensForETH, etc.)
Uniswap V3 (exactInputSingle / exactInput) — if needed
Support for WETH wrap/unwrap if necessary
Safe approvals (preferably "approve max once")
Return of tokens/ETH to the owner
Access control: owner-only / authorized caller
Optionally: multi-call / atomic sequence (buy → approve → sell) in one transaction
Recommendations for the pipeline of private bundles
We plan to send privately through builders/relais (e.g., Titan Builder), need best practices:
nonce, simulations, handling revert
strategy for replacing bundles
how to debug/trace more conveniently
Quality
Clean code, comments, and tests (preferably Foundry)
Security notes: threats/edge cases (MEV, approvals, reentrancy, etc.)
Simple configuration: routers, fee tiers, slippage parameters
What is already available
The radar triggers are ready (we can trigger webhook/message/internal call).
precise networks (ETH)
Your experience (MEV/searcher, Uniswap V2/V3, private bundles)
Volume assessment (MVP vs extended)
What we need from you to start (networks, routers, preset amounts, etc.)
We will agree on the price!
Thank you!
