DVote Storage Proofs
Javascript/Typescript library to generate storage proofs for ERC token contracts.
The library is heavily inspired on the prior work of @izqui on evm-storage-proofs.
Usage
Instal with NPM:
npm install @dvote/storage-proofsconst tokenAddress = "0x1234..."
const holderAddress = "0x2345..."
const balancePositionIdx = 1
const balanceSlot = ERC20Prover.getHolderBalanceSlot(holderAddress, balancePositionIdx)
const storageProover = new ERC20Prover(jsonRpcUri)
const data = await storageProover.getProof(tokenAddress, [balanceSlot], blockNumber, true)
const { proof, block, blockHeaderRLP, accountProofRLP, storageProofsRLP } = data
// ...
