Try the AppLayer public testnet

You do not need to start by running a node.

Start with the public testnet. Test tokens have no real value, so you can learn without risking real money.

1. Add the network to your wallet

Use these settings in MetaMask or another EVM wallet:

• Network name: AppLayer Testnet
• RPC URL: https://testnet-api.applayer.com/
• Chain ID: 75338
• Currency symbol: APPL
• Explorer: https://testnet-explorer.applayer.com/

Check the official testnet guide before you begin. It is the source of truth if a setting changes.

2. Get test tokens

Use the faucet linked from the official guide. Paste in your testnet wallet address and request APPL test tokens.

These tokens are only for testing.

3. Pick a code path

Want the familiar path? Deploy a Solidity contract through Remix like you would on another EVM network. Set the compiler target to Shanghai, connect Remix to your wallet, and choose the AppLayer Testnet.

Want the C++ path? Start with the C++ contract documentation. The public testnet guide shows how to use the ContractManager interface to create one of the compiled C++ contract templates available on the network.

4. Check what happened

Open the testnet explorer and search for your wallet address or transaction hash.

You should be able to see the transaction, its status, and the block that saved it.

Keep the first test small

Deploy one simple contract. Call one function. Read one result.

Once that works, build the next piece.

Small test. Clear result. Then grow.
