I'm working on designing a custom spending script for a UTXO using a P2TR (Pay-to-Taproot) output, where the spending condition requires a signature from a multi-party computation (MPC) wallet to be verified at the time of spending. In my research, I found OP_CHECKMULTISIG, which supports multisig wallets, but my use case is different since I’m specifically aiming to integrate an MPC wallet signature check within a Taproot script, rather than a standard multisig setup.
Can anyone provide guidance or examples on how to implement this in a P2TR script? Are there specific opcodes, Taproot-specific features (like Schnorr signatures or script leaves), or techniques I should explore to achieve this custom spending condition?
