mfer-node is an Ethereum transaction simulator based on go-ethereum.

What can mfer-node do

• Provide a standard web3 rpc like geth provides, so you can use a wallet to connect to it.
• Connect to most of Ethereum web3 rpc and fork the network.
• Detect missing state and re-fork at latest block heigh automaticlly.
• Local mempool to keep state mutation.
• Block pinning by adding a postfix @height
• Trace blocks by specific range (Optimised for L2).
• Auto merge batch request so you can even use a public RPC to get a good trace performance.
