MuSig2 v0.4.0

This package contains an exact copy of the MuSig2 code as found in github.com/btcsuite/btcec/v2/schnorr/musig2 at the tag btcec/v2.2.2.

This corresponds to the MuSig2 BIP specification version of v0.4.0.

We only keep this code here to allow implementing a backward compatible, versioned MuSig2 RPC.

Unsupported Methods

The following methods from the newer MuSig2 specifications are not supported in this legacy v0.4.0 implementation and will return ErrUnsupportedMethod if called:

  • CombinedNonce(): Returns error instead of the combined nonce.
  • RegisterCombinedNonce(): Returns error instead of registering a pre-aggregated combined nonce.

These methods are only available when using MuSig2 v1.0.0rc2 or later. To use these features, create sessions with MuSig2Version100RC2 instead of MuSig2Version040.
