Guidance on Implementing MuSig in a Taproot Keypath Spend

[Minghell0x]

Hello,

I am working on implementing multisig functionality using the MuSig protocol for a taproot keypath spend, and I could use some guidance.

I understand that MuSig allows for multisig transactions that are indistinguishable from regular transactions by aggregating multiple signatures into a single one that can be verified from a single public key.

I have found examples of script-path spend with multisig but these are distinguishable as multisig transactions due to the Bitcoin script. What I am looking for is a way to do this with a keypath spend to maintain the privacy advantages of single-sig transactions.

I am hoping for some guidance on how to implement these steps using the bitcoinjs library. Any code examples or general advice would be greatly appreciated.

Thank you for your help.
