MPT Noir includes tools to prove Ethereum Merkle Patricia Trie (MPT) proofs.


Installation

In your Nargo.toml file, add the following dependency:

[dependencies]
mpt = { tag = "v0.2.0", git = "https://github.com/radni/mpt-noir" }

Simple Usage

The mpt-noirjs package is made to facilitate witness generation for mpt-noir circuits. To generate inputs for address "MY_ADDRESS" against the latest block you can use the following:


const provider = new ethers.JsonRpcProvider("RPC_URL")
const address = "MY_ADDRESS"
const output = await provider.send("eth_getProof", [address, [], "latest"])
const mpt_proof = getNodesFromProof(output.accountProof, address)

The mpt_proof contains all the data necessary to generate proof using the mpt-noir circuits. To see an elaborated example you can checkout Balance Proof application.
