Contract interactions
The contracts are wired together. Here's who calls what:
| Caller | Contract | When |
|---|---|---|
| User wallet | IntentRegistry | When placing an order |
| Coordinator | IntentRegistry | To open and close batch windows |
| Solver | BatchAuction | To submit a solution |
| BatchAuction | BatchSettlement | When declaring an auction winner |
| BatchSettlement | SolverBond | To slash a solver that fails to settle |
| Solver | SolverBond | To deposit or withdraw their bond |
Supported tokens
Every token used in an intent must be whitelisted in the AssetRegistry contract. IntentRegistry.commit_intent calls AssetRegistry.is_whitelisted for both asset_in and asset_out before accepting the intent — an unlisted token is rejected on-chain.
| Token | Symbol | Address (Sepolia) | Decimals | Status |
|---|---|---|---|---|
| USD Coin | USDC | 0x053b40a647cedfca6ca84f542a0fe36736031905a9639a7f19a3c1e66bfd5080 | 6 | Pending whitelist |
| Wrapped BTC | WBTC | Bridge from Ethereum Sepolia via Starkgate | 8 | Pending whitelist |
To whitelist a token, the admin account calls whitelist_asset on the AssetRegistry. Once whitelisted, solvers can fill intents for that pair and settlement will execute the token transfer.
