# Gas Station contract addresses

## EVM chains

Built with ERC-4337 compatible smart contracts, Gas Station for Circle Wallets
allows developers to sponsor network fees for SCA wallet users. If a transaction
meets the policies you set, Gas Station calls these contracts to cover the
network fee.

The following are the smart contract addresses that power Gas Station on EVM
blockchains:

<Note>
  **Solana**

  Gas Station on Solana is powered by fee-payers: programs that cover network fees
  for users on your behalf. If a transaction meets the policies you set, Gas
  Station calls the fee payer to sponsor the network fee of the transaction. Gas
  Station is available on both mainnet and devnet.
