Status-react: Explore getting token transaction history entry

[goranjovic]

User Story

As a user I want to see my ERC20 token transactions in the transaction history along with eth transactions.

Description

Type: Feature

Summary: Right now ERC20 token transactions do not show in the transaction history screen, simply because we get that information from Etherscan API and there is no publicly available service that offers that data. However, token transactions still leave some trace in the transaction history - there are special 0 ETH entries with some extra ether for the spent gas for every token transaction.

We should explore getting the needed data (token amount, specifically) from those entries.

We already figured this out at Trust Wallet.
Open source repo: https://github.com/TrustWallet/trust-ray

/transactions?address=0xe47494379c1d48ee73454c251a6395fdd4f9eb43 will return all the ether and ERC20 transfers.

@vikmeup Care to share some details about how you implemented it? :)

[vikmeup]

It is open source, you take a look, but in the short summary.
We build trust-ray for three main reason:

• fetch transactions per specific address
• fetch all the tokens for specific address
• send push notifications for received and sent transfers or tokens for specific address

Trust-ray parses every block on the blockchain and look for events that’s generated by ERC20 contracts or ether and stored them in DB(MongoDB).

You are doing the lord’s work Viktor
