I need more information. What is it that you would like beyond the types that we already export (eg. TransactionSigner, MessageSigner, TransactionSendingSigner, etc.).

createMint has payer: Signer parameter, but it must be a Keypair, wallet adapter is not possible.

I'm not sure that I understand the premise.

Signer is defined as follows:

https://github.com/solana-labs/solana-web3.js/blob/maintenance/v1.x/src/keypair.ts#L7-L10

The body of that createMint function uses payer in two positions, one at which it accesses payer.publicKey and another where it's used in a position that expects Array<Signer>.

Perhaps you'll have more luck debugging your program by posting a question on Stack Exchange.

Other than that, I encourage you to explore the new 2.0 library. The 1.0 library about which this issue was filed will be end-of-lifed next year.
