Send a Gasless Transaction

This step-by-step guide lays out the process for sending gasless transactions from your wallet on Testnet. Gasless transactions are no different than any other Programmable Wallet transaction. As long as a Gas Station policy is configured, and you use a supported wallet, gas fees will be sponsored automatically.

Before you begin, it's important to understand which blockchains support gasless transactions and the wallet types supported on each.

• The following EVM chains support smart contract accounts (SCAs) for gasless transactions:

  • Arbitrum: Mainnet, Sepolia testnet
  • Avalanche: Mainnet, Fuji testnet
  • Base: Mainnet, Sepolia testnet
  • Ethereum: Mainnet, Sepolia testnet
  • Optimism: Mainnet, Sepolia testnet
  • Polygon: Mainnet, Amoy testnet
  • Unichain: Mainnet, Sepolia testnet

• Aptos supports externally owned accounts (EOAs)

• Solana supports externally owned accounts (EOAs)

To create a wallet, follow our comprehensive quickstart guide on creating your first developer-controlled wallet. Remember, you must create an SCA wallet for EVM chains to perform gasless transactions while you must create an EOA wallet on Solana. Once the wallet is successfully created, note down the wallet's address from step 3.

Alternatively, if you prefer to use user-controlled wallets, follow the Create Your First Wallet guide.

Next, you will fund your wallet with a token to provide an asset for conducting transactions. In this guide, we will transfer USDC into the wallet using the USDC faucet. While on the faucet, provide your wallet's address to complete the process.

Alternatively, if you prefer to deposit a native token, you can visit the ETH or MATIC faucets.

Follow the instructions in the quick start guide Transfer Tokens from Wallet to Wallet. This guide will walk you through sending a transaction without requiring gas. Once completed, you can head to the developer dashboard policies page and view the sponsored transaction within the respective policy.

For those using user-controlled wallets, follow the Send an Outbound Transfer instead.
