Sep 12

On this page

Etherspot is a blockchain development framework for EVM-compatible chains that creates direct state channel bridges to provide a seamless user experience across chains and wallets. Requirements:

Node.js

Create a new node project

Lets create an empty node project

Terminal

mkdir etherspot
cd etherspot
npm init -y

Install etherspot

Terminal

npm install ethers@^5.5.2 reflect-metadata@^0.1.13 rxjs@^6.6.2 -S
npm install --save etherspot
npm install ws -s

The js code for index.js

Here we import etherspot and below instanciate the sdk class and call signMessage method to sign the message.

src/index.js

import { Sdk, randomPrivateKey } from 'etherspot';
 
const PRIVATE_KEY = randomPrivateKey();
 
async function main() {
  const sdk = new Sdk(PRIVATE_KEY);
 
  const signature = await sdk.signMessage({
    message: "message to sign",
  });
 
  console.log('signature', signature);
}
 
main().catch(console.error);

Output

Terminal

"0x2be06de5d41e1de4682341d915b9a337cf5ba2f63a55f6674ca85deeb08d67f772b79888324fc61c5d9bfd05fafe7276a0cb4a610252ab4559db624921802cc11b"

Get token lists

src/index.js

import { Sdk, randomPrivateKey } from 'etherspot';
 
const PRIVATE_KEY = randomPrivateKey();
 
async function main() {
  const sdk = new Sdk(PRIVATE_KEY);
 
  const output = await sdk.getTokenLists();
 
  console.log('token lists', output);
}
 
main().catch(console.error);

Output

Terminal
