    Pay gas in tLCX, not ETH

    Activate your Smart Account once, then send transactions on Liberty Chain Testnet paying gas in tLCX tokens. Works with MetaMask, Coinbase Wallet, Rabby, Trust — any standard wallet.

    Connect your wallet to begin.

    How it works

    Step 1

    Deploy your Smart Account

    A deterministic contract address derived from your wallet address. Your wallet (EOA) owns and signs for the Smart Account. One-time deploy via the SimpleAccountFactory.

    Step 2

    Approve the paymaster

    A second one-time transaction lets the paymaster pull tLCX from your Smart Account to cover gas. After this you never need native ETH again.

    Step 3

    Send gasless txs

    Each transaction is a UserOperation signed by your wallet. The paymaster pays ETH gas to the sequencer, deducts the equivalent tLCX from your Smart Account.
