Minimal set of protocol messages for integration:

• HsmdInit2

• SignWithdrawal (general L1 signing, but also needed for sweeping closed channel to L1 wallet)
• GetPerCommitmentPoint2
• NewChannel
• SetupChannel
• ValidateCommitmentTx2
• RevokeCommitmentTx
• ValidateRevocation
• SignRemoteCommitmentTx2
• SignLocalCommitmentTx2
• SignMutualCloseTx2

if you don't want to maintain your own node secret (also see NodeInfo above):

• Ecdh
• SignMessage
