Stagenets
Stagenets are private EVM testnets that replicate real chains by replaying their blocks.
They give you a persistent staging environment with production-like state and built-in tools for testing smart contract behaviour before launch.
Stagenets are powered by Mainnet Replay, which keeps your Stagenet in sync with the chain it replicates while preserving changes made by your own transactions.
Stagenets vs forks vs public testnets
| Environment | Good for | Staging fit |
|---|---|---|
| Local fork | Fast one-off tests against a snapshot of mainnet. | Local and short-lived, with no shared team environment or UI for analysis. |
| Public testnet | Public deployment rehearsal and frontend/wallet testing. | State, liquidity, oracle values, and activity differ from production. Observability and simulation tools usually need to be custom built. |
| Stagenet | Production-grade staging before mainnet. | A persistent private testnet that follows real chain state, with powerful built-in tools and analytics. |
Using a Stagenet
Each Stagenet exposes a standard Ethereum JSON-RPC endpoint, so you can use it with your existing stack:
- Hardhat
- Foundry
- Wallets
- ethers.js
- viem
- deployment scripts
- frontends
Think of them as a drop-in upgrade for your current testnet.
Agents, scripts, and tools can also control Stagenets programatically using our CLI and SDK.
What each Stagenet includes
Each Stagenet comes with the tools you need to effectively test contracts before mainnet:
- Workspaces — dashboards for contracts and wallets, showing activity, assets, state, and tracked data.
- Contract Imports — import contracts from GitHub or the CLI and activate Workspaces automatically when they are deployed.
- Developer Tools — faucets, wallet generation, user activity scheduling, and account impersonation.
- DeFi Integrations — protocol-aware tooling for Chainlink, Uniswap, and other DeFi systems.
Supported chains
