CTxDestination

using CTxDestination = std::variant<CNoDestination, PubKeyDestination, PKHash, ScriptHash, WitnessV0ScriptHash, WitnessV0KeyHash, WitnessV1Taproot, WitnessUnknown>

A txout script categorized into standard templates.

• CNoDestination: Optionally a script, no corresponding address.
• PubKeyDestination: TxoutType::PUBKEY (P2PK), no corresponding address
• PKHash: TxoutType::PUBKEYHASH destination (P2PKH address)
• ScriptHash: TxoutType::SCRIPTHASH destination (P2SH address)
• WitnessV0ScriptHash: TxoutType::WITNESS_V0_SCRIPTHASH destination (P2WSH address)
• WitnessV0KeyHash: TxoutType::WITNESS_V0_KEYHASH destination (P2WPKH address)
• WitnessV1Taproot: TxoutType::WITNESS_V1_TAPROOT destination (P2TR address)
• WitnessUnknown: TxoutType::WITNESS_UNKNOWN destination (P2W??? address) A CTxDestination is the internal data type encoded in a bitcoin address

Function Documentation

ExtractDestination()

bool ExtractDestination	(	const CScript &	scriptPubKey,
		CTxDestination &	addressRet
	)

Parse a scriptPubKey for the destination.

For standard scripts that have addresses (and P2PK as an exception), a corresponding CTxDestination is assigned to addressRet. For all other scripts. addressRet is assigned as a CNoDestination containing the scriptPubKey.

Returns true for standard destinations with addresses - P2PKH, P2SH, P2WPKH, P2WSH, P2TR and P2W??? scripts. Returns false for non-standard destinations and those without addresses - P2PK, bare multisig, null data, and nonstandard scripts.
