⛽ Gas-Sponsoring Relayer RPC

Ethereum Mainnet • Flashbots MEV protection • Gasless meta-transactions

How to use: Add the RPC URL below as a custom network in MetaMask (chain 1). All your transactions will route privately through Flashbots — no frontrunning, no mempool exposure. Sponsored addresses transact with zero ETH balance via JIT gas bundles.

⚙️ How It Works

1
You sign a transaction in MetaMask (unstake, claim, transfer…). Your wallet builds and signs the tx with your private key as normal.
2
Relayer intercepts the signed raw transaction. If your address is gas-sponsored, it builds a Flashbots bundle: a JIT ETH transfer from the gas tank → your address, followed immediately by your tx.
3
Flashbots lands both atomically in the same block. Gas tank funds arrive and are spent in the exact same block — no window for the sweeper bot to grab them.
4
msg.sender = your address on-chain. Because your private key signed the transaction, the contract sees your address — not the gas tank's. Works for staking, unstaking, and claiming.

🧪 Test Meta-Transaction (/relay endpoint)

Signs an EIP-712 meta-tx with MetaMask and sends to the /relay endpoint. Gas is paid by the gas tank. Connect MetaMask first.

No wallet connected.
