I’ll try to keep this topic up to date as well as answer questions. I hope it is helpful for someone:
Part 1:
We launch an ICRC 1, 2, 3, 4, and 10 compatible token on Internet Computer.
Things you will need:
git - Git - Installing Git
dfx - support.dfinity.org/hc/en-us/articles/10552713577364-How-do-I-install-dfx
mops - mops.one/
motoko vs code extension - Motoko - Visual Studio Marketplace
fork icrc_fungible - GitHub - PanIndustrial-Org/ICRC_fungible: A full implementation of an ICRC 1,2,3 compatible fungible token
get a canister - nns.ic0.app/ (You will need a couple ICP)

Part 2:
In this video we:
- Set up your local Internet Computer Replica to run NNS canisters including a fake ICP Ledger.
- Send our selves fake ICP
- Write code that let’s us mint ICDevs tokens from ICP
- Write code that lets ICDevs withdraw ICP to the ICDevs Neuron that funds our charity.

The ICDevs Neuron: Neuron: ICDevs.org - ICP Dashboard
To Mint $ICDevs
Access the ICP Ledger from Candid UI: DFINITY Canister Candid UI
Step 1. Log in.
Step 2. Send ICP to the principal you are assigned
Step 3. Call icrc2_approve with an amount in e8s ( 1ICP = 100000000 - a one and 8 zeros . Minimum is 1000000 e8s) and the spender owner of agtsn-xyaaa-aaaag-ak3kq-cai
Access the $ICDevs ledger from Candid UI: DFINITY Canister Candid UI
Step 1. Log in
Step 2. Call MintFromICP with the same amount you approved and set your target to a plug wallet principal(recommended). Do not set your nns.ic0.app principal as a target or you will not be able get to your tokens.
Steps in dfx(you must have ICP in your dfx account):
dfx canister --network ic call ryjl3-tyaaa-aaaaa-aaaba-cai icrc2_approve ‘(
record {
fee = opt (10_000 : nat);
memo = null;
from_subaccount = null;
created_at_time = null;
amount = 100_000_000 : nat;
expected_allowance = null;
expires_at = null;
spender = record {
owner = principal “agtsn-xyaaa-aaaag-ak3kq-cai”;
subaccount = null;
};
},
)’
dfx canister --network ic call agtsn-xyaaa-aaaag-ak3kq-cai mintFromICP ‘(
record {
source_subaccount = null;
target = opt record {
owner = principal “{your-plug-principal}”;
subaccount = null;
};
amount = 100_000_000 : nat;
},
)’
Add $ICDevs to your plug with canister ID agtsn-xyaaa-aaaag-ak3kq-cai and type ICRC1.

Hey @skilesare, when I go to Candid UI and click the login button, it takes me to https://identity.internetcomputer.org/#authorize which does not show my II’s. But, if I go to https://identity.ic0.app/#, my II’s are there. Is one of these login links deprecated, or should I be able to log in to Candid UI somehow using either one? Or are these two links totally unrelated to each other and used for different purposes? I’m a bit confused. Thanks in advance.

Good question! I think both will get you the same II principal because they use the same mapping between number and domain for delegation, but I’d prefer that someone from DFINITY confirm. I think that @nmattia is/was on that team? (Sorry for the tag if not)
As a test you could log in on both and see if you get the same principal. In either case, only send enough ICP there that you want to use for the mint and you have a low downside. Or send a small amount first.
I’m obviously missing something because I don’t see how I can log in using the https://identity.ic0.app/#? I’m using Safari, and when I go to that link, my II’s show up without a problem. But then I copy/paste the link to the Candid UI, go there, and it says I have to log in. So, I click the login button at the top right of the Candid UI page, and it takes me to https://identity.internetcomputer.org/#authorize , which doesn’t show my II’s.
I realize it’s probably trivial to log into the II’s again on the other page, but it doesn’t sound like that’s necessary? I’m not seeing how I can use my II’s that are already set up at ic0.app instead of having to set them up again at internetcomputer.org though.
Huh…interesting…I just tried with my same number and it didn’t prompt for my key…unexpected. Let me see why this is the case. I also wonder who at dfinity is responsible for deploying candid ui. Maybe it hasn’t been updated in a while? Or maybe they want you to use that url now?
Edit: Ok…I can confirm that at some point they started using two different domains for safety:
I’d advise setting up keys at both domains in case one ever gets added to the black list again.
Awesome, thanks for digging into the history for me and finding an explanation! I’ll migrate over to the internetcomputer.org logins.
Hey @skilesare, I was able to successfully mint ICDevs tokens, but there was a small discrepancy in what I had to do vs your instructions.
I initially deposited 0.5 ICP or 50000000 in e8s. When I called the MintFromICP function using the same amount I approved, it gave me an error saying I had an insufficient balance and all that was available was 4999000. So, I just put that number in and it was successful. So when converting from one to the other, a transaction fee is subtracted. Not a big deal at all, but figured you may want to note it for future instructions. Hope it helps!

Thank you! I’ll fidget with it. Once the app is up I’ll make the fees easier for the users to understand.
