Interface SwapExactQuantityParams

Amount of the input side to swap, in the input coin's own decimal units. Only used to auto-fund a fresh input coin from the sender's wallet — verified directly against the real @mysten/deepbook-v3 source (swapExactQuantity in dist/transactions/deepbook.mjs), which does baseCoin ?? coinWithBalance({..., balance: convertQuantity(amount, ...)}). If you pass an explicit baseCoin/quoteCoin (e.g. a coin produced earlier in the same PTB, as PayStreamer's routed-payment flow does), that coin's entire value becomes the input and amount is ignored.

DeepBook charges trading fees in its own DEEP token, separate from the coins being swapped. Callers must supply how much DEEP they're willing to spend and, in deepCoin, a coin to draw it from — this is a real cost the original conceptual routing.mdx example omitted entirely.

true: swap the pool's base asset for its quote asset. false: quote for base.

Minimum acceptable output — the slippage guard.
