Step 4: Odin canister calls

In this step, you’ll learn how to use your Internet Computer identity from Step 3 to make canister calls.

This step builds on Step 3: Authenticate with Odin API. Make sure you have a working Internet Computer identity before proceeding.

What You’ll Accomplish

By the end of this step, you’ll have:

✅ Connected to the Odin canister using your authenticated identity
✅ Made your first canister call to deposit BTC
✅ Verified the functionality of your integration

Odin Canister Integration

Import Canister Interface

Let’s start by setting up the Odin canister interface. You can reference the contract and download the interface from the Internet Computer Dashboard.

Configuration Setup

Create the necessary configuration files for your project:

...

// Odin Trading Canister IDs by environment
export const ODIN_CANISTER_IDS = {
  development: 'w5cxm-6iaaa-aaaaj-az4jq-cai',
  staging: 'z2vm5-gaaaa-aaaaj-azw6q-cai',
  production: 'z2vm5-gaaaa-aaaaj-azw6q-cai',
} as const;

// Default canister ID (can be overridden by environment)
export const ODIN_CANISTER_ID = process.env.ODIN_CANISTER_ID || ODIN_CANISTER_IDS.development;

Environment Configuration

Development
Production

const ODIN_CANISTER_ID = 'w5cxm-6iaaa-aaaaj-az4jq-cai';

Use this endpoint for development and testing purposes. Doesn’t require BTC

const ODIN_CANISTER_ID = 'z2vm5-gaaaa-aaaaj-azw6q-cai';

Switch to this endpoint when deploying to production.

Deposit BTC

This is only for development and testing purposes. This method is not exposed in production. For onchain deposits, use the corresponding deposit address of the coin/token/rune.

To interact with any canister method, we just need to create an actor based on that identity.

utils/odin.ts

import { Actor, HttpAgent } from "@dfinity/agent";
import { DelegationIdentity } from "@dfinity/identity";
import { OdinActor } from "../types/odin";
import { DEFAULT_IC_HOST, ODIN_CANISTER_ID } from "../constants/canister";
import { idlFactory as OdinIdlFactory } from '../canister/odin_canister.idl';

export const getActor = (identity: DelegationIdentity): OdinActor => {
    // Step 1: Create an authenticated actor with the identity
     const agent = new HttpAgent({ identity, host: DEFAULT_IC_HOST });
     const odinActor = Actor.createActor(OdinIdlFactory, {
       agent,
       canisterId: ODIN_CANISTER_ID,
     }) as OdinActor;

     return odinActor;
}

You can view more canister methods here.

Testing the Deposit Function

Let’s test our identity by calling a function in the Odin canister:

index.ts

import { login, prepare } from './core/prepare';
import { createSampleWallet } from './sample-wallet';
import { authenticateCallback } from './core/auth-callback';
import { getActor } from './utils/odin';


(async () => {
  const wallet = await createSampleWallet();
  const result = await prepare(wallet.address);

  const signature = await wallet.signMessage(result.message);

  const identity = await login({
    address: wallet.address,
    message: result.message,
    signature: signature,
    publicKey: wallet.publicKey,
    signatureType: 'Bip322Simple',
  });

  // Used for API calls.
  const token = await authenticateCallback(identity);

  const odin = getActor(identity);

  const BITCOIN = {
    id: 'btc',
    name: 'Bitcoin',
    ticker: 'BTC',
    image: 'https://upload.wikimedia.org/wikipedia/commons/4/46/Bitcoin.svg',
    rune: null,
    divisibility: 8,
    decimals: 3,
  };

  const btc = 0.001; 
  const amount = BigInt(btc * 10 ** (BITCOIN.divisibility + BITCOIN.decimals));
  const newBalance  = await odin.token_deposit(BITCOIN.id, amount);

  console.log({
    newBalance,
  });
})();

Run the test:

npx tsx index.ts

{ newBalance: 10000000n }

Great! You’ve successfully integrated with Odin!
