A simple node.js server for retrieving truffle-style ProjectInfo for a given Ethereum contract.

• Fetches contract data from etherscan (if verified)
• Can easily be extended to support Sourcify later (for decentralization)
• Handles fetching solidity compilers, and caches them locally
• Operates deterministically, so can be parallelized and placed behind a load balancer for serving at scale.

Can be used to represent complex tx parameters, even nested structs.

yarn to install dependencies.

Make sure your system has Docker installed.

Copy the sample.env file to .env, and fill in an infura URL, etherscan key, and desired port to serve on, to use as a server.

To host as a server, run yarn start.

The server accepts requests at /tx, with query parameters from, to, and data (per ethereum transaction fields).

To improve performance by pre-fetching solidity compilers, you can run yarn obtain.

yarn test
