This page contains meta info for Filecoin developers about the Calibration testnet.

Please visit the Filecoin Docs - Networks - Calibration for the most up-to-date info.

Overview

The Filecoin Calibration testnet is a stable testnet that follows Filecoin mainnet closely. It has fewer resets and is intended for longer-term testing efforts from storage providers and developers.

• Like mainnet, Calibration supports 32 GiB, and 64 GiB storage sectors.
• It has a Storage Provider auto-accepting new deals from developers (see Resources - Calibration Storage Providers below).

Join Quickstart

• Build: https://lotus.filecoin.io/lotus/manage/switch-networks
• Stats: See Resources - Block Explorers below
• Faucet: https://faucet.calibnet.chainsafe-fil.io
• Snapshots: https://forest-archive.chainsafe.dev/list

User Quickstart

1. Add the Calibration testnet to your wallet (e.g. MetaMask).
   • Go to https://chainlist.org/chain/314159
   • Click on "Connect wallet"
2. Create a new account in MetaMask to use with Filecoin.
3. Use https://faucet.calibnet.chainsafe-fil.io to request funds to your Ethereum address (it will be converted behind the scenes to a Filecoin f410 address)
4. Follow the transaction in one of the recommended Calibration testnet explorers:
   • https://beryx.zondax.ch
   • https://fvm.starboard.ventures
5. Your account is now funded and can be used in Ethereum tools such as Hardhat, Foundry, Remix, etc.
