<p>create OP_VAULT stub (BIP 345 Closed, vault opcodes, BIP 443 successor)</p> <p><b>New page</b></p><div>&#039;&#039;&#039;OP_VAULT&#039;&#039;&#039; was a proposed pair of [[Taproot]] script opcodes defined in [https://github.com/bitcoin/bips/blob/master/bip-0345.mediawiki BIP 345]. Together with CHECKTEMPLATEVERIFY (CTV, BIP 119), the opcodes were intended to give consensus support for vault-style custody. A vault locks coins under a delayed withdrawal path while preserving an always-available recovery path. BIP 345 has BIP status Closed, with BIP 443 (OP_CHECKCONTRACTVERIFY) listed as the proposed replacement. The authors withdrew further advocacy for the vault-specific opcodes in May 2025 in favor of that more general covenant design, which can still express vault constructions.<br /> <br /> A typical BIP 345 vault is a Taproot output whose script tree contains at least two leaves. One leaf uses &lt;code&gt;OP_VAULT&lt;/code&gt; to authorize a trigger spend. The other uses &lt;code&gt;OP_VAULT_RECOVER&lt;/code&gt; to send funds to a predetermined recovery destination. Triggering the vault produces an intermediate output that still carries the recovery leaf and replaces the vault leaf with a timelocked CTV script describing the intended withdrawal. After the relative delay elapses, a withdrawal that matches the CTV template can claim the coins. At any time before that withdrawal confirms, a recovery spend can sweep the funds. BIP 345 never activated on Bitcoin mainnet.<br /> <br /> == See also ==<br /> <br /> * [[Taproot]]<br /> * [[Script]]<br /> <br /> == External links ==<br /> <br /> * [https://github.com/bitcoin/bips/blob/master/bip-0345.mediawiki BIP 345: OP_VAULT]<br /> * [https://github.com/bitcoin/bips/blob/master/bip-0443.mediawiki BIP 443: OP_CHECKCONTRACTVERIFY]<br /> * [https://delvingbitcoin.org/t/withdrawing-op-vault-bip-345/1670 Withdrawing OP_VAULT (BIP 345)]<br /> * [https://bitcoinops.org/en/topics/vaults/ Bitcoin Optech: Vaults]<br /> <br /> [[Category:Technical]]</div>
