How It Works
The intent lifecycle from submission to accountability, in 5 steps.
User Submits Intent
A user expresses what they want (e.g., swap 1 ETH for USDC at best price). The intent is formatted as an ERC-7683 cross-chain order with an intentHash.
The intent specifies constraints (minimum output, deadline) but not the execution path. The solver decides how to fulfill it.
Solver Executes
A registered solver picks up the intent and executes it on-chain. The solver must have an active bond (minimum 0.1 ETH staked in the SolverRegistry).
Solvers choose execution strategies: direct swaps, multi-hop routing, cross-chain bridges, or aggregation. The method is up to the solver; the outcome must meet the intent constraints.
Receipt Posted On-Chain
After execution, the solver posts a cryptographic receipt to the IntentReceiptHub. The receipt includes the intentHash, constraintsHash, evidenceHash, and solver signature.
V2 receipts add dual attestation: both solver and client sign via EIP-712. Privacy levels (public, semi-public, private) control what data is visible on-chain vs. stored off-chain.
Challenge Window Opens
A 1-hour challenge window begins. During this period, anyone can dispute the receipt by providing evidence and posting a dispute bond.
Deterministic violations (timeout expired, wrong amount) are resolved automatically. Complex disputes use optimistic resolution: the solver has 24 hours to post a counter-bond, or the challenger wins by default.
Finalization & Reputation Update
If no dispute is filed during the challenge window, the receipt finalizes. The solver's IntentScore is updated based on the outcome.
If a dispute was filed and resolved against the solver, the bond is slashed: 80% to the user, 15% to the challenger, 5% to the treasury. After 3 jailings, the solver is permanently banned.
Implementation Status
Protocol contracts and EIP-7702 delegation contracts are live on Sepolia testnet. Solver and watchtower are chain-connected with Cloud KMS signing and real on-chain data queries. Receipt posting, dispute resolution, and automated monitoring work end-to-end.
