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 @vocdoni/storage-proofs-eth

const 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  // ...

储存证明

Javascript/Typescript库为ERC令牌契约生成存储证明。

该库的灵感来源于@izqui先前关于evm存储证明的工作。

使用方法

安装NPM:

npm install @vocdoni/storage-proofs-eth

const 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  // ...
