Mechanics

How it works.

01
Two counterparties register a bilateral commitment containing a trigger sqrtPrice and the size of each leg.
02
On every swap the hook reads live price via StateLibrary.getSlot0 against the pool's current state.
03
When spot crosses the trigger, the commitment settles atomically in a single transaction.
04
Collateral transfers via ERC-20 safeTransfer — no intermediary custody, no escrow contract.

Integration

Code sample.

// Register a bilateral OTC commitment
bcsHook.submitCommitment(
    poolKey,
    counterparty,        // address of other party
    triggerSqrtPrice,    // execution price as sqrtPriceX96
    token0Amount,        // amount of token0 to deliver
    token1Amount         // amount of token1 to receive
);
