Hi,

I’m just wondering which npm package implements icrc_2_transfer_from. I was thinking it would be @dfinity/ledger but I get dependency errors so thinking i might be looking in the wrong place:

This one should do the trick, should also work on the ICP ledger as it supports icrc:

@dfxjesse you ever seen this before when making a transfer:

Here is the function that calls it:

async function saveEuro2024Predictions(
dto: Euro2024PredictionDTO,
): Promise {
try {
const identityActor = await ActorFactory.createIdentityActor(
authStore,
process.env.FOOTBALL_GOD_BACKEND_CANISTER_ID ?? “”,
);

  if (dto.alreadyEntered) {
    const result = await identityActor.submitEuro2024Prediction(dto);
    console.log(result);
    if (isError(result)) {
      console.error("Error saving Euro2024 prediction.");
      return;
    }
    return result;
  }

  const ledger = IcrcLedgerCanister.create({
    agent: ActorFactory.getAgent(),
    canisterId: Principal.fromText("avqkn-guaaa-aaaaa-qaaea-cai"),
  });

  authStore.subscribe(async (auth) => {
    let transfer_result = await ledger.transfer({
      to: {
        owner: Principal.fromText(
          process.env.FOOTBALL_GOD_BACKEND_CANISTER_ID ?? "",
        ),
        subaccount: [auth.identity?.getPrincipal().toUint8Array() ?? []],
      },
      fee: 100_000n,
      memo: undefined,
      from_subaccount: undefined,
      created_at_time: BigInt(Date.now()),
      amount: 100_000_000_000n,
    });
    console.log(transfer_result);
  });
} catch (error) {
  console.error("Error saving Euro2024 prediction.", error);
  throw error;
}

}
