Introduction

contract.dev provides staging and observability for on-chain applications.

Use Stagenets to test against live chain state before you deploy. Use Contract Observability to understand and monitor your contracts in production.

Stagenets — private EVM testnets that replay production chain state, with built-in dev tools.
Contract Observability — production analytics and monitoring for deployed contracts.

Contract Observability

Watch your deployed contracts to get dashboards showing their transactions, TVL, volume, users, asset flows, counterparties, and more.

Stagenets

Create a private EVM environment that follows production chain state. Deploy and test against real contracts, liquidity, prices, accounts, and other on-chain state without touching mainnet.

Stagenets come with built-in tools: a block explorer, contract dashboards, a faucet, account impersonation, state and function overrides, and more.
