Examples

Create a Multi-Chain Wallet

import { WDK } from '@tetherto/wdk';
import { WalletManagerEvm } from '@tetherto/wdk-wallet-evm';
import { WalletManagerTon } from '@tetherto/wdk-wallet-ton';

const wdk = new WDK(seed)
  .registerWallet('ethereum', WalletManagerEvm, { rpcUrl: ETH_RPC })
  .registerWallet('polygon', WalletManagerEvm, { rpcUrl: POLYGON_RPC, chainId: 137 })
  .registerWallet('ton', WalletManagerTon, { rpcUrl: TON_RPC });

// Get accounts
const ethAccount = await wdk.getAccount('ethereum', 0);
const polygonAccount = await wdk.getAccount('polygon', 0);
const tonAccount = await wdk.getAccount('ton', 0);

Execute a Token Swap

import { SwapProtocolParaswap } from '@tetherto/wdk-swap-paraswap';

wdk.registerProtocol('paraswap', SwapProtocolParaswap, {});

const account = await wdk.getAccount('ethereum', 0);
const swap = account.getSwapProtocol('paraswap');

await swap.swap({
  srcToken: USDC_ADDRESS,
  destToken: USDT_ADDRESS,
  amount: '1000000000',
  slippage: 1,
});

Bridge Assets Cross-Chain

import { BridgeProtocolUSDT0 } from '@tetherto/wdk-bridge-usdt0';

wdk.registerProtocol('usdt0', BridgeProtocolUSDT0, {});

const account = await wdk.getAccount('ethereum', 0);
const bridge = account.getBridgeProtocol('usdt0');

await bridge.bridge({
  destChain: 'polygon',
  amount: '1000000000',
  recipient: recipientAddress,
});
