What is Shadow?

Shadow is a platform that reduces engineering time and costs for advanced on-chain data indexing and analytics. It helps users obtain more data, save gas, and accelerate product development.

The first product allows users to log any desired information on any smart contract without using gas. It offers a production-grade infrastructure for Shadow events, enabling users to obtain custom on-chain data with just a few lines of code.

Shadow enables users to modify the source code of deployed contracts to add gasless custom event logs and view functions on a shadow fork that mirrors the mainnet state in real-time.

Shadow provides users with tools and infrastructure to:

• Spin up a new shadow fork with a single click

• Augment any contract with custom event logs and view functions

• Instantly access data via standard RPC methods

• View a real-time feed of shadow events from new transactions

• Quickly backfill and export data for historical transactions

Shadow is a fully hosted platform that manages various aspects, including:

• Nodes for both the shadow fork and public chain

• Real-time synchronization of state, including re-orgs

• Compilation and deployment of contracts on the shadow fork

• Proxy patterns and application of changes to all factory-created contracts

• Shadow fork and public chain RPC endpoints

• Export of decoded and indexed event data
