eip7702-rescue

Forensic MCP + hardened delegate for recovering assets from EIP-7702-compromised wallets.

When an EOA is delegated to a sweeper via EIP-7702, you can't fund it to pay for its own recovery — the funding is swept on arrival. This tool rescues the held assets in one atomic sponsored type-4 transaction (re-delegate + transfer-out, no window for the attacker), and ships a forensic MCP that is key-free: it diagnoses, scans, and simulates recoverability for any victim address without ever holding a private key. Firing the real rescue is a deliberate, separate human step.

Quickstart

forge build                 # compile contracts/RescueDelegate.sol
node mcp/server.mjs          # run the MCP server over stdio

Register mcp/server.mjs as a stdio MCP server in your client. RESCUE_RPC overrides the RPC.

The hardened delegate

RescueDelegate(address SAFE) — destination immutable at deploy. rescue(wrap, ids) can only ever move assets to SAFE, so it's safe to leave delegated (no open-destination drain window).

Composition

A rescue job's asset_set + outcome bind to an OCP/8281 artifact_hash → recovery-escrow receipt (faithfulness) + scope-contestation (completeness). The MCP is the observation/action front-end of the recovery-standards family; no trusted party at any layer.
