Note (Base era): As of 2025-07-25, Aavegotchi’s canonical home migrated to Base. Legacy Polygon testnets (Mumbai/Amoy) are not the primary reference chain for the wiki anymore. See Migration to Base (2025).

This page shows how to connect your wallet to Base Sepolia (Base testnet) so you can use Aavegotchi test environments (when available) and view Base Sepolia contracts.

Getting Sepolia ETH

1). Use a reputable Sepolia faucet to obtain test ETH.

2). In MetaMask, ensure you’re on Base Sepolia (chain id 84532).
