Upgrade NNS canister: Chain Fusion Signer

Governance NNS proposal discussions
1

Dear All,

There is a relatively new NNS canister called the chain fusion signer. It can be used to access the Internet Computer threshold signing APIs directly from web browsers, off-chain clients and other-chain clients.

In proposal 134424 we would like to add Schnorr signatures to the canister API. In particular it adds the schnorr_public_key() and schnorr_sign() methods, that correspond to the methods in the IC canister API: Signing with t-Schnorr | Internet Computer

We have verified that the Schnorr API can be used to sign Solana transactions.

The release also includes various maintenance upgrades.

Please consider voting on the proposal.

Best wishes, Max

Is it possible to sign TON transactions?

@rassul TON uses ed25519 so I would tentatively say yes, probably, but with cryptography details matter. I would wish to get a demo working to confirm that it is indeed so.
