Ethers·js

What is Ethers.js?​

The Ethers.js library offers a collection of tools to interact with Ethereum nodes using JavaScript, similar to Web3.js. Atleta Olympia also has a similar API that is fully compatible with Ethereum's JSON RPC invocations. This means that developers can take advantage of this compatibility and use the Ethers.js library to interact with a Atleta Olympia node as if it were an Ethereum node.

Getting Started with Ethers.js​

1. Create a JavaScript Project to store all of the files you'll be creating mkdir ethers-examples && cd ethers-examples

2. Install the Ethers.js library and the Solidity compiler npm install ethers solc@0.8.0

Setting up Ethers Provider​

1. Import the ethers library

2. Define the providerRPC object, which can include the network configurations for any of the networks you want to send a transaction on.

3. Create the provider using the ethers.providers.StaticJsonRpcProvider method. An alternative is to use the ethers.providers.JsonRpcProvide(providerRPC) method, which only requires the provider RPC endpoint address.

   // 1. Import ethers
   const ethers = require('ethers');
   
   // 2. Define network configurations
   const providerRPC = {
   manta: {
       name: 'Atleta Olympia',
       rpc: 'https://testnet-rpc.atleta.network', // Insert your RPC URL here
       chainId: 2340, //Insert your ChainID Here
   },
   };
   // 3. Create ethers provider
   const provider = new ethers.providers.StaticJsonRpcProvider(
   providerRPC.constellation.rpc,
   {
       chainId: providerRPC.constellation.chainId,
       name: providerRPC.constellation.name,
   }
   );

Note: Ensure that all of your smart contracts are deployed on the Atleta Olympia chain and that you have updated contract addresses on the front-end.
