Getting Started #

The Cardano wallet SDK library provides class with batch of methods that helps to manage user's stake.

Install the npm library by copying the code below.

$ npm install @everstake/wallet-sdk-cardano

or you can also use yarn

$ yarn add @everstake/wallet-sdk-cardano

This code example how to make Cardano instance. The paymentAddress should be in correct format - bech32. To create instance also need to get a blockFrostProjectID. More details can be found here https://blockfrost.io/ . Be careful when use network. (preview and preprod are testnets)

import {CardanoWeb3} from "cardano-web3-js"
import {Cardano} from "@everstake/wallet-sdk-cardano";

const web3 = new CardanoWeb3({network: "preview"});
const mnemonic = '...';
const account = web3.account.fromMnemonic(mnemonic);
const blockForstProjectID = '...';

const cardano = new Cardano('preview', account.__config.paymentAddress, blockForstProjectID);

(Optionally) Methods registerAndDelegateCborHexTx() and delegateCborHexTx() required information about pool. It automatically calls
selectPool() methods, that is a bit slowly. But it can be preloaded if selectPool() will be lazy loaded before delegations methods to save some time.

const cardano = new Cardano('preview', account.__config.paymentAddress, blockForstProjectID);
await cardano.selectPool(); // preloaded
const tx = await registerAndDelegateCborHexTx() // selectPool() will skipped
