web3.js plugin for Aurora NEAR engine

This is an npm package containing a web3.js plugin for Aurora NEAR engine.

Aurora is an EVM-compatible blockchain built as a smart contract atop NEAR blockchain. This plugin would leverage Aurora custom RPC methods (https://doc.aurora.dev/evm/rpc/) and other custom behavior enabled at Aurora especially Cross-Contract Calls (XCC). More on Aurora XCC at https://github.com/aurora-is-near/aurora-contracts-sdk.

Plugin usage by users

At your typescript project first run: yarn add web3 @conx3/web3-plugin-aurora

And here is how to use the plugin:

import { Web3 } from 'web3';
import { AuroraPlugin } from '@conx3/web3-plugin-aurora';

async function aurora() {
  const web3 = new Web3('https://mainnet.aurora.dev');
  web3.registerPlugin(new AuroraPlugin(web3.provider));

  const blockNumber = await web3.aurora.getBlockNumber();
  console.log('aurora blockNumber', blockNumber);

  const parityPendingTransactions =
    await web3.aurora.parityPendingTransactions();
  console.log('aurora parityPendingTransactions', parityPendingTransactions);
}

aurora();

NEAR Aurora Plugin

Create NEAR Aurora Plugin and publish it to the npm registry

The web3.js plugin for NEAR Aurora has been publish to
https://www.npmjs.com/package/@conx3/web3-plugin-aurora and it is useable inside this example playground: https://codesandbox.io/p/sandbox/misty-leftpad-v7249s?file=%2Findex.js. Additionally, some tests has been written to test some of the basic functionality.

web3.aurora is also accessible as web3.near.aurora

Aurora plugin could be used now as web3.near.aurora. However, its registration needs a bit of simplification. A PR would be opened later on web3.js registry for this and similar use cases.

Enable all Ethereum RPC methods on AuroraPlugin

Now all Ethereum RPC methods are callable on web3.aurora (and on web3.near.aurora as a consequence). However, there is a small modification needed to not expose the unsupported methods on web3.aurora and the AuroraPlugin class.

Support custom RPC methods on AuroraPlugin (the non-basic-Ethereum)

Some of the custom RPC endpoints available at Aurora Engine are now callable on AuroraPlugin as an example of this functionality. However, some of them seems to not be yet implemented in the current version running the main net and test net. Even though, they is marked as completed at: https://doc.aurora.dev/evm/rpc. So, this need to be double checked.

NEAR Plugin

There is a web3.js plugin for the NEAR protocol. Check its repository at: https://github.com/conx3/web3-plugin-near

Running Tests

Testing AuroraPlugin

Executing yarn test aurora.test.ts would give something like:

 PASS  test/aurora.test.ts

    AuroraPlugin can call the additional Aurora endpoints
      ✓ should call `parityPendingTransactions` (195 ms)
      ○ skipped should call `txpoolStatus`
      ○ skipped should call `txpoolInspect`
      ○ skipped should call `txpoolContent`
