UtxoSpend

data class UtxoSpend(val intentHash: String, val outputNo: Int, val value: BigInteger, val owner: String, val ownerPublicKey: String, val tokenType: String)

Represents a UTXO being spent (input) in an unshielded transaction.

Source: Based on midnight-ledger UtxoSpend structure File: midnight-ledger/ledger/src/structure.rs

Purpose:

References an existing UTXO by intentHash and outputNo
Specifies the owner address (for signature verification)
Includes value and token type for balancing

CRITICAL: The blockchain identifies UTXOs by intentHash + outputNo.

Usage in Transaction:

val input = UtxoSpend(
    intentHash = "87eb8bd03bfb2cd7...",  // Intent hash from indexer
    outputNo = 0,
    value = BigInteger("1000000"),  // 1.0 NIGHT
    owner = "mn_addr_undeployed1...",
    tokenType = "0000...000"  // NIGHT token
)
