SuperCall TypeScript SDK

The SuperCall SDK is a library that allows developers to interact with SuperCall smart contracts more easily. It provides the necessary tools to construct cross-chain multicall transactions. The SDK's core functionality is encapsulated within the Call class.

Installation

Include the SDK in your project by adding it to your dependencies:

npm install --save @super-call/sdk

Features

• Simple Transaction Construction: Easily create transactions for interaction with SuperCall smart contracts.
• Sub-Calls Management: Add, remove, and manage sub-calls within a call.
• Fee Calculation: Automatically calculate the total fee for the call and its sub-calls.
• Call Encoding: Encode the call for transaction submission.

Quickstart

Create a Call

async function createCall(source, destination) {
    const chainId = destination.chainId;
    const target = destination.loggerContract.address;
    const callData = getLogCallData(`Call from ${source.chainId} to ${destination.chainId}.`);
    const lzSuperCall = destination.contract.address;
    const fee = await calculateCallFee(source, destination);
    return new LzCall(chainId, target, callData, lzSuperCall, fee);
}

Construct Calls and Sub-Calls

const call1 = await createCall(source, moonbeam);
call1.addSubCall(await createCall(moonbeam, fantom));
call1.addSubCall(await createCall(moonbeam, ethereum));
// ...

Calculate Total Fee and Encode Calls

const fee = calls.reduce((a, b) => (Number(a) + Number(b.calculateTotalFee())), 0).toString();
const encodedCalls = calls.map(call => call.encode());

Submit Transaction

const tx = await source.contract.aggregate(encodedCalls, { value: fee });
console.log("Submit transaction successfully: ", tx.hash);
