I am able to transfer funds from one **connected account** to another _not connected account_ simply by using the icp ledger in js. but now i want to transfer funds the other way arround.  
If what i was doing before was send tokens now i want to recieve them is there a possible way for it in a reactjs app which is 100% on chain.

Are you looking for `icrc2_transfer_from`? [ICRC-1/standards/ICRC-2/README.md at main · dfinity/ICRC-1 · GitHub](https://github.com/dfinity/ICRC-1/blob/main/standards/ICRC-2/README.md)

You can have your canister blanket-approve a large amount (say `u64::MAX`) and then you can `icrc2_transfer_from` whenever you want, but the canister will have to call `icrc2_approve` once to set this up

Yes, you can approve any valid principal to spend on your behalf

</div>

so i could do something like:

```auto
public shared ({caller}) func gimme_money() : Bool {
  <If the caller deserves money> 
   ledger.transfer(to:<callers'accountid>,amount: <what he deserves>);
   return true;
  <else>
   return false;
}

```

</div>

You can do that. If you use `ledger.transfer` you will always spend your own tokens (so since this is in a canister you would spend the canister’s tokens). If you want to spend tokens of some other account you have to use `ledger.icrc2_transfer_from`

Yes i get that, Thank you very much!!!  
But how can i call ledger’s methods from a motoko canister is it just like how we do normal inter-canister calls or is it different?

</div>

The ledger is a canister like any other canister. You can use the normal inter-canister calls. It’s just a bit ‘more important’, otherwise there’s nothing special about it

</div>

yes and in normal cansiter call we declare the methods we want to use by creating the actor like:

```auto
let ledgerCanister = actor ('ryjl3-tyaaa-aaaaa-aaaba-cai') : actor {
      transfer : (to : Principal, amount : Int) -> async Bool;
  };

```

its not complete ik but do we have to declare all the methods we want to use or is ther a predefined way to achieve this

</div>

The recommended setup is [here](https://internetcomputer.org/docs/current/developer-docs/integrations/ledger/ledger-local-setup), then you can use the ledger in Motoko with `import LEDGER "canister:ledger";`

I am got this error when tried to call the approve method on my local ledger.  
ICRC-2 features are not enabled on the ledger., error code None

from what i found on the docs. i have to deploy an icrc1 ledger with ` feature_flags = opt record{icrc2 = true};` but i dont really want to create my own tokens and interact with them i want to interact with the icp ledger and its (icp)tokens.

</div>

You only deploy the ledger yourself if you’re developing locally on your machine. For mainnet you won’t deploy your own.

To turn on ICRC-2, you need to add the `feature_flag` field to the init args like this:

```auto
dfx deploy --specified-id ryjl3-tyaaa-aaaaa-aaaba-cai icp_ledger_canister --argument "
  (variant {
    Init = record {
      minting_account = \"$MINTER_ACCOUNT_ID\";
      initial_values = vec {
        record {
          \"$DEFAULT_ACCOUNT_ID\";
          record {
            e8s = 10_000_000_000 : nat64;
          };
        };
      };
      send_whitelist = vec {};
      transfer_fee = opt record {
        e8s = 10_000 : nat64;
      };
      token_symbol = opt \"LICP\";
      token_name = opt \"Local ICP\";
      feature_flags = opt record {
        icrc2 = true;
      };
    }
  })
"

```

Sorry to bother again but it is releated to the issue so:

I was able to do it locally as you’ve mentioned but when i deploy my canisters on main-net and i want to allow my canister to use my masterWallets token i got stuck.  
what i tried was to use the icrc2\_approve method on the dfx ledger but it doesn’t have a method like that so the question is :  
How am i supposed to allow a canister on mainnet to use my icp tokens from icp ledger “ryjl3-tyaaa-aaaaa-aaaba-cai” using the icrc2\_approve method

</div>

You have to call the function manually using `dfx canister call`.

```auto
dfx canister --network ic call ryjl3-tyaaa-aaaaa-aaaba-cai icrc2_approve '( record {
  amount = <amount in e8s>;
  spender = record {
     owner = principal "<canister id>";
  };
})'

```

This is the command iam running  
`dfx canister call ryjl3-tyaaa-aaaaa-aaaba-cai icrc2_approve "(record { amount = 10_000_000_000_000_000; spender = record{owner = principal \"my-canister-id\";} })" --network ic`

````auto
And i get this error

Maybe try `amount = 10_000 : nat`?

If I add `: nat` to the amount it works for me:

```auto
❯ dfx canister call ryjl3-tyaaa-aaaaa-aaaba-cai icrc2_approve "(record { amount = 10_000_000_000_000_000: nat; spender = record{owner = principal \"aaaaa-aa\";} })" --network ic
(variant { 17_724 = 9_232_450 : nat })

```
