Gas-Free Transactions with Stablecoins

Revolutionary RPC solution that eliminates gas tokens. Transact on any chain using USDC with any wallet - no bridging, no specialized wallets, no dApp integration required.

How It Works

Our solution combines Circle CCTP v2 and ChainLink Data Feeds to enable seamless gas abstraction

1. Configure RPC

Replace your MetaMask RPC with our custom endpoint

2. Approve USDC

Approve our vaults to spend USDC for gas conversion

3. Auto Swap

We automatically swap USDC for gas using ChainLink feeds

4. Execute

Transaction executes seamlessly with converted gas

Setup Instructions
Follow these steps to start using gas-free transactions

Step 1: Add Custom RPC to MetaMask

MetaMask Configuration:

  1. Open MetaMask and go to Settings → Networks
  2. Click "Add Network" or edit existing network
  3. Replace the RPC URL with: http://localhost:8545
  4. Save the configuration
