How to use Wormhole SDK

Token Transfers

Code

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 import { Chain, Network, TokenId, TokenTransfer, Wormhole, amount, isTokenId, wormhole, } from "@wormhole-foundation/sdk"; // Import the platform-specific packages import evm from "@wormhole-foundation/sdk/evm"; import solana from "@wormhole-foundation/sdk/solana"; import { SignerStuff, getSigner, waitLog } from "./helpers/index.js"; (async function () { // Init Wormhole object, passing config for which network // to use (e.g. Mainnet/Testnet) and what Platforms to support const wh = await wormhole("Testnet", [evm, solana]); // Grab chain Contexts -- these hold a reference to a cached rpc client const sendChain = wh.getChain("Avalanche"); const rcvChain = wh.getChain("Solana"); // Shortcut to allow transferring native gas token const token = Wormhole.tokenId(sendChain.chain, "native");

Example Output

1 2 3 4 5 6 7 8 9 10 11 (async function () { // Init Wormhole object, passing config for which network // to use (e.g. Mainnet/Testnet) and what Platforms to support const wh = await wormhole("Testnet", [evm, solana]); // Grab chain Contexts -- these hold a reference to a cached rpc client const sendChain = wh.getChain("Avalanche"); const rcvChain = wh.getChain("Solana"); // Shortcut to allow transferring native gas token const token = Wormhole.tokenId(sendChain.chain, "native");
