Gasless Transactions

RibbleChain's account abstraction (ERC-4337) enables gasless transactions, where users don't pay gas fees directly. This guide explains how to perform gasless transactions using a RibbleChain smart wallet.

How Gasless Transactions Work​

  • Paymaster: A third party (e.g., dApp or RibbleChain) covers gas fees.
  • Smart Wallet: Executes transactions via the EntryPoint contract.
  • UserOperation: Bundles transaction data for gasless processing.

Prerequisites​

Step 1: Connect to a dApp​

Open the RibbleChain Wallet app and connect to a dApp (e.g., DEX):

  • Click "Connect Wallet."
  • Approve the connection.

Step 2: Perform a Gasless Transaction​

Example: Swap tokens on the DEX:

  • Select tokens to swap (e.g., $XRB to $RST).
  • Confirm the transaction in the wallet app.
  • The paymaster covers gas fees, and you pay no $XRB for gas.

Step 3: Verify Transaction​

Check the transaction on the RibbleChain Explorer:

  • Search by transaction hash.
  • Confirm the gas fee was zero for the user.

Step 4: Enable Gasless Mode (MetaMask)​

For MetaMask users, enable gasless mode:

ribblechain-cli wallet config --gasless true
