Simple library to decode ethereum transaction and logs

### Install

```bash

$ npm install --save @maticnetwork/eth-decoder

```

### Usage

**Log parser**

```js

import { LogDecoder } from "@maticnetwork/eth-decoder"

const ERC20TokenABI = /* { .... } */ // ABI for ERC20 token contract

// create decoder object

const decoder = new LogDecoder(

  [

    ERC20TokenABI,

    // ... other ABIs

  ]

);

// parse logs

const parsedLogs = decoder.decodeLogs(receipt.logs) // For truffle testsuite, use `receipt.receipt.logs`

console.log(parsedLogs)

```

**Tx parser**

```js

import { TxDecoder } from "@maticnetwork/eth-decoder"

const ERC20TokenABI = /* { .... } */ // ABI for ERC20 token contract

// create decoder object

const decoder = new TxDecoder(

  [

    ERC20TokenABI,

    // ... other ABIs

  ]

);

// parse tx

const parsedTx = decoder.decodeTx({ data: '0x..', value: '1000', from: '...', ... })

console.log(parsedTx)

```
