Often times, you might want to make multiple transaction calls to a ledger canister. Doing this sequentially takes a long time. So, on behalf of a new stealth project :grin:, and while we wait for ICRC-4, I built icrc2-batch , a Motoko ICRC-2 library specifically tailored for parallel execution of a…

This was my first time really using PicJS and getting it set up in CI. Ran into a few issues along the way, but man is it so much faster than dfx. Thanks so much @NathanosDev ! Also, I’d like to give a shout out to @quint and his testing.mo library. It uses the interpreter and essentially allows yo…

IMO icrc2 should be deleted and never mentioned again :smiley: my extreme opinion. It’s a thing that worked for EVM, but it doesn’t mean it will work on the IC. ICRC3 and 4 are all you need. Perhaps 3 can be improved a bit by allowing the requester to filter it by from & to Principal. In the app yo…

I don’t disagree that ICRC-4 will be a big improvement over ICRC-1/2, but in my experience these things take quite awhile to get rolled out. Do you or others have any idea how far ICRC-4 is from being rolled out? This might be a discussion for another thread, but there seems to be quite a bit of di…

Sounds like a burn the ships on the shore type of approach that is not realistic in the context of decentralized coordination. Many ledgers including the “protocol native” (ICP, ckEtc) ones support the ICRC 1/2 standards today, and it’s an improvement over the fractured and unfunctional state of aff…

[image] icme: Can you elaborate on this part? How is this the same thing, especially if you are not custodying the funds. In the case of ICRC2 we have the dapp frontend (most of the times) getting access to the funds and can spend them while the user is using the dapp. In the other they are i…

[image] infu: IMO icrc2 should be deleted and never mentioned again :smiley: my extreme opinion. It’s a thing that worked for EVM I agree with you technically and in a perfect world where all technology works all the time with no bugs, but the experience where users hits your dApp obliterates…

Security & legally it’s the same thing, having access to the tokens with ‘approve’ or them being in your canister. You certainly should probably not ever approve a canister with ICRC2 that isn’t open sourced And/or Blackhoked/dao governed/Someone you really, really trust. That is why we gave sub…

[image] skilesare: By only pulling the funds at exactly the point when the service can provide what is promised, you create atomicity that eliminates a million unknown unknowns. I don’t see it exactly like that. If the approved transfer call fails to return a response but takes the tokens, yo…

Sorry for hijacking the thread with generic ICRC2 talk, let me get back to the point. I am assuming this library is used by Cycleops. If you had a smart contract account like {owner: canister, subaccount: Principal} then you could easily send out hundreds of ICP transactions to Cycles to canisters …
