DO NOT MERGE.

Some notes I took when I discussed ICRC-34 with Frederik.

Hey, David @peterpeterparker, when will oisy-wallet-signer support ICRC-34?

I want to use OISY Wallet to connect to the anda_x402_canister, and I need it to support two functions:

1. Call the anda_x402_canister's next_nonce() interface;
2. Sign a paymentPayload.

Hi @zensh
At the moment, we don't plan to implement support for icrc-34 in OISY because of security concerns.
(But we do encourage to implement icrc-21 support in all service canisters for offered functions.)
