Good After Time (GAT) API

Good After Time orders are time-delayed programmatic orders that execute only after a specified timestamp, featuring optional price checking and off-chain buy amount determination.

Key Parameters

Parameter	Description
`sellToken` / `buyToken`	The token pair for the trade
`receiver`	Where proceeds are sent
`sellAmount`	Quantity of tokens to trade
`minSellBalance`	Balance threshold preventing duplicate fills
`startTime` / `endTime`	UNIX timestamps for order validity window
`allowPartialFill`	Solver flexibility setting
`priceCheckerPayload`	Optional price validation data
`appData`	IPFS hash reference

Price Validation

When enabled, the price checker validates that:

buyAmount >= (expectedOut * (MAX_BPS - allowedSlippage)) / MAX_BPS

Where MAX_BPS equals 10,000 basis points.

Error Handling

Error	Condition
`PollTryAtEpoch`	Block timestamp precedes `startTime` (“too early”)
`OrderNotValid`	Owner lacks required sellToken balance (“balance insufficient”)
`PollTryNextBlock`	Insufficient expected output given slippage tolerance (“price checker failed”)

The implementation supports flexible buy amounts while maintaining replay protection through balance verification.
