decoder-api

Serverless API for decoding Ethereum transactions and logs, using Etherscan as a source of contract ABIs

Introduction

This package describes an API Gateway and Lambda API that exposes two endpoints

• POST /decode-logs {"logs":[...]} returns {"decodedLogs":[...]}
• POST /decode-transactions {"transactions":[...]} returns {"decodedTransactions":[...]}

The idea is that you can pass Ethereum logs or transactions and receive the logs or transactions with the arguments decoded. It uses Etherscan as a source of truth for ABIs.
