Introduction

The contract.dev platform provides Stagenets — private, persistent test networks that continuously replay mainnet blocks and maintain synchronised chain state.

Rather than freezing at a single block like local forks, they advance block-by-block, so contracts are executing against the same historical chain state that existed on mainnet at each block.

Each Stagenet is enhanced with a suite of integrated development tools — from contract analytics and CI/CD to DeFi simulations and debugging utilities.

They function as a collaborative staging environments where teams can build, test, analyse, and iterate on contracts in a production-like setting before deploying to mainnet.
