What's necessary to sign a transaction is well known, I don't see how driving any hardware wallet from the wallet itself or from a third party daemon implementing that URL scheme would make any difference, other than providing better devices interoperability, as well as easier maintenance and update paths for the wallets. -- Nicolas Bacca | CTO, Ledger ___ bitcoin-dev mailing list bitcoin-dev@lists.linuxfoundation.org https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev

The NXP JCOP platform (found in Yubico Neo) is a popular choice, and then you can add your own custom logic for validation. -- Nicolas Bacca | CTO, Ledger ___ bitcoin-dev mailing list bitcoin-dev@lists.linuxfoundation.org https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
