Shadow is a platform that enables gasless custom event logging and advanced onchain data indexing to power analytics and applications.
Shadow is a web3 data platform designed to simplify and accelerate the process of accessing and indexing onchain data. It enables developers to add custom, gasless event logs and view functions to any existing smart contract by creating a shadow fork — an offchain execution environment that mirrors mainnet state in real time. This approach allows teams to obtain precise, decoded, and indexed onchain data without the overhead of managing node infrastructure or building complex data pipelines.
The platform targets developers and product teams building analytics dashboards, DeFi tools, and other applications that require detailed onchain insights. Shadow's infrastructure handles syncing state, managing re-orgs, compiling and deploying contracts on the shadow fork, and providing RPC endpoints for seamless data access. Users can spin up a shadow fork with one click, augment contracts with custom events, and instantly query data via standard RPC methods or export it for further analysis.
What sets Shadow apart is its permissionless, gasless event logging system that does not increase gas costs for end users, enabling richer data capture without trade-offs. It supports quick iteration cycles with familiar tooling and offers deep data coverage, including net-new events that are otherwise difficult to obtain. Shadow is fully hosted, reducing engineering time and costs associated with onchain data indexing. Notable use cases include building advanced Uniswap v3 dashboards and other DeFi analytics products. Developers can get started quickly by signing up with a Google account and following the comprehensive documentation and quickstart guides available on the platform.
Developers face challenges in accessing detailed, custom onchain data without incurring high gas costs or managing complex infrastructure. Existing solutions often require building and maintaining data pipelines or running full nodes, which increases engineering overhead and slows iteration.
