Interface Recipient

BTC amount in satoshis.

Assets to send to the same recipient (assetId & amount)

The recipient contract's tapleaf set (VtxoScript.encode form), published on this output's PSBT_OUT_TAP_TREE so its spending paths are recoverable from the transaction alone — an address commits only to the output key.

Refused unless it derives the recipient address's taproot key, and it must come from VtxoScript.encode(): leaf depths are ignored on read and the tree is rebuilt in arkd's canonical shape, so a tree from another encoder is refused even where it commits to the same address.
