Usage

Browser:

import { Masa } from "@masa-finance/masa-sdk";
import { providers } from "ethers";

// with metamask
const provider = new providers.Web3Provider(window.ethereum);
const signer = provider.getSigner();

// by default Masa SDK will assume the provider points to ethereum mainnet and
// will load contracts accordingly. If you plan to connect to a different network
// the networkName must be specified i.e. like this: networkName: "goerli"

export const masa = new Masa({
  signer,
  // networkName: "goerli",
});

Node:

import { Masa } from "@masa-finance/masa-sdk";
import { providers, Wallet } from "ethers";

const provider = new providers.JsonRpcProvider("your blockchain rpc endpoint");
const wallet = new Wallet("your private key", provider);

// by default Masa SDK will assume the provider points to ethereum mainnet and
// will load contracts accordingly. If you plan to connect to a different network
// the networkName must be specified i.e. like this: networkName: "goerli"

export const masa = new Masa({
  signer: wallet,
  // networkName: "goerli",
});
