@lattice/xswap-sdk

SDK for cross-chain atomic swaps via XSwap protocol.

Installation

bun install

Usage

import { XSwap, ChainId, DWalletAddress } from '@lattice/xswap-sdk';

const xswap = new XSwap({
    suiClient,
    packageId: XSWAP_PACKAGE_ID,
    xswapSharedObjectData,
    xcoreSharedObjectData,
    registrySharedObjectData,
});

// Create a new swap request
const tx = xswap.newRequest({
    depositProof,
    sourceChain: ChainId.Solana,
    destinationChain: ChainId.Sui,
    destinationAddress: userSuiAddress,
    minDestinationAmount: 1000000n,
});

// Settle a request (solver)
const tx = xswap.settleRequest({
    requestId,
    settleProof,
});

// Withdraw funds after settlement
const tx = xswap.withdrawRequest({
    requestId,
    withdrawProof,
    presignCapId,
});

Proof Parsers

// Parse enclave proofs
const depositProof = XSwap.parseNewRequestProof(raw);
const settleProof = XSwap.parseSettleProof(raw);
const withdrawProof = XSwap.parseWithdrawProof(raw);

Wallet Keys

| Chain | Wallet Key | |-------|------------| | Solana | 0 | | Sui | 1 |
