Ithaca SDK

This is official JS SDK for Ithaca Protocol

SDK Initialization

import { IthacaSDK, IthacaNetwork } from "@ithaca-finance/sdk";

const wsCallbacks = {
  onClose: (ev: CloseEvent) => { /*do something*/ };
  onError: (ev: Event) => { /*do something*/ };
  onMessage: (payload: SocketOrder) => { /*do something*/ };
  onOpen: (ev: Event) => { /*do something*/ };
}

const ithacaSDK = new IthacaSDK(
  IthacaNetwork.ARBITRUM_GOERLI,
  // Refer: https://wagmi.sh/react/hooks/useWalletClient / https://viem.sh/docs/clients/wallet.html
  walletClient, // optional, if walletClient is undefined SDK will be initialized in Read-Only mode
  wsCallbacks, // optional web socket callbacks
  <BACKEND_API_URL>, // optional backend url override
  <BACKEND_WEBSOCKET_URL> // optional backend websocket url
);

Auth module

• Login - Establishes authenticated session with Ithaca backend. Essential for interacting with Ithaca protocol. Ithaca SDK must be initialized with WalletClient in order to use this method

const result = await ithacaSdk.auth.login();

// Sample output
{
  "authToken": "ynQPpVleu8lQMfXc0Cedc9p6xjXjypFVQTBhRtHsjn0=",
  "clientId": 1723710844499969,
  "ethAddress": "0x7a1dbec6f1203f89942766314be0f36fd4615704"
}

• Logout - Closes authenticated session with Ithaca backend

await ithacaSDK.auth.logout();

• Get session info - Get information about current authenticated session with Ithaca backend

const result = await ithacaSDK.auth.getSession();

// Sample output
{
  "authToken": "ynQPpVleu8lQMfXc0Cedc9p6xjXjypFVQTBhRtHsjn0=",
  "clientId": 1723710844499969,
  "ethAddress": "0x7a1dbec6f1203f89942766314be0f36fd4615704"
}

Calculation module

• Estimate order payoff - Returns graph coordinates object for order payoff, where key is x coordinate and value is y coordinate

1. clientOrderId - unique client order id, use createClientOrderId
2. totalNetPrice - unit price of order, use calculateNetPrice
3. legs - order legs contract id, side and quantity;
4. fwdPrice - should be set to reference price if payoff is Forward (optional)
5. addCollateral - should be set to true if collateral is needed (defaults to false)

const order = {
  clientOrderId: 1739781756044389,
  totalNetPrice: 10,
  legs: [
    {
      contractId: 231117024,

      contractId: 231117012,
      quantity: "9.999",
      side: "BUY"
    }
  ],
};
const result = await ithacaSdk.calculation.estimateOrderPayoff(order);

Helper functions

• Unit price (net price) - Calculate unit price for an order

1. legs - order legs with contract id, side and quantity
2. referencePrices - reference prices for all contract ids
3. precision - strike currency precision of selected currency pair
4. unitSize - unit size (defaults to 1)

import { calculateNetPrice } from "@ithaca-finance/sdk";

const unitPrice = calculateNetPrice(legs, referencePrices, precision, unitSize);

• Client order id - Creates a unique client order id

import { createClientOrderId } from "@ithaca-finance/sdk";

const clientOrderId = createClientOrderId();

• Calculate collateral requirement - Get required collateral for the order

1. leg - order leg contract id, side and quantity
2. payoff - order payoff e.g. Call, Put
3. strike - order strike
4. precision - precision of strike currency

const collateral = ithacaSdk.calculation.calcCollateralRequirement(leg, payoff, strike, precision);
