2. Wallet Setup
Install a wallet matching the chain you want to test:
| Chain | Wallets |
|---|---|
| EVM (Ethereum, Arbitrum, Base, Polygon, ...) | MetaMask, Coinbase Wallet, Rabby |
| Solana | Phantom, Solflare |
Switch your wallet to a testnet before testing:
| Chain | Testnet | RPC / Network setting |
|---|---|---|
| Ethereum | Ethereum Sepolia | Built-in to MetaMask (enable testnets in settings) |
| Arbitrum | Arbitrum Sepolia | https://chainlist.org/chain/421614 |
| Base | Base Sepolia | https://chainlist.org/chain/84532 |
| Solana | Devnet | Phantom → Settings → Developer Settings → Change Network → Devnet |
