💡Wallet Features

MetaPro brought together the essential features that allow Users to migrate smoothly from the old-fashioned Ethereum wallets.

Your transactions are not just secure—They're profitable.

No-revert Transactions

The approved transactions pass a Simulation-Process through MetaPro's Ethereum nodes to be labelled as no-revert.

Your transaction won't be mined if it includes any reverts, so you don't pay for failed transactions!

Gas Optimized Transactions

By Implementing manual AccessList - EIP2930 generation for each transaction, MetaPro provides more optimized transactions by lowering the gas costs for users! how?

What is AccessList?

The accessList specifies a list of addresses and storage keys that the transaction plans to access, allowing a discount gas rate relative to the cost of accessing outside the list.

— From EIP2930

Example AccessList:

[
    [
        "0xde0b295669a9fd93d5f28d9ec85e40f4cb697bae",
        [
            "0x0000000000000000000000000000000000000000000000000000000000000003",
            "0x0000000000000000000000000000000000000000000000000000000000000007"
        ]
    ],
    [
        "0xbb9bc244d798123fde783fcc1c72d3bb8c189413",
        []
    ]

Private Transactions

The MetaPro's MEV-Bot bundles the User's transaction and adds them as a back-run transaction to each bundle per block.

What is a Private Transaction?

Typically all pending transactions are exposed to the public mempool to get picked by miners, however, a private transaction bypasses the public mempool and is sent privately to the chosen block builders.

Private Transactions are protected against back-running, front-running attacks (a.k.a Sandwiching, Arbitrage, ... )

The bundle will be sent privately to top block builders (eg. Flashbots, beaverbuild, Titan Builder, Builder0x69, ...) via eth_sendBundle API method.
