Gasless for users

Your users never hold native gas. Settlement runs on EIP-7702 — the user signs two off-chain messages, a relayer broadcasts the set-code transaction and pays gas, and all costs are skimmed atomically from the swept tokens. Works even from a wallet holding only ERC-20s and zero native token.

🔒

Non-custodial & atomic

Pull, swap, skim fees, and hand off to the delivery engine all happen in a single reverting transaction. We never advance value without repayment. No custody, no credit risk.

🌐

Any ERC-20, any chain

Every quote is gated by the Token Risk Engine — liquidity-depth check, oracle/DEX price sanity, honeypot simulation, and tiered classification — not a static allow-list.

MCP Server for AI agents

@sweepster/mcp is a stdio Model Context Protocol server exposing the sweep API as tools — get_quote, submit_signed, get_intent_status, gen_integration_snippet, and more — so an AI agent or Claude Code can drive sweeps and manage a builder account without hand-written API client code.

Security notice: Audit and bug bounty are planned before mainnet value moves. The SweepDelegate contract is deployed deterministically at the same address on four Sepolia testnets — Base, OP, Arbitrum, and World Chain — and mainnet deployment is gated on an external security audit.
