Consider using scure-btc-signer

[paulmillr]

scure-btc-signer is an audited low-level bitcoin library, alternative to bitcoinjs.

Feature list is quite extensive: PSBT / UTXO handling, tx construction and such. The library utilizes noble cryptography which you're already using.

@paulmillr hey, thank you for the suggestion. We will investigate if it makes sense to switch from bitcoinjs-lib.

Second support for Paul's library, @leather.io is built with btc-signer
