CREAM Tracking Hacker Transactions
Getting Started
- Get an API key from https://streamingfast.io
- Download a release from the releases
- Start the tracker
Install
Build from source:
GO111MODULE=on go get github.com/streamingfast/cream-track-hacker/cmd/tracker
Or download a self-contained binary for Windows, macOS or Linux.
Usage
export STREAMINGFAST_API_KEY="server_......................"Then simply launch the tracker:
trackerThe binart starts a never ending stream that receives all Ethereum blocks, analyze their transactions
and notify when a transaction is doing a pure Ether Transfer (from/to) or a ERC20 Transfer
(from/to) coming from one of the tracked address (defaults to 0x560a8e3b79d23b0a525e15c6f3486c6a293ddad2
and 0x905315602ed9a854e325f692ff82f58799beab57).
The notification is sent to the standard output, can be enhanced to send email, send a Slack or WeChat message, etc.
The file cursor.txt saved in the current directory must be kept and persisted, it's the marker
that tells the stream where to start back at. If the file is non existant, the stream starts by default
from block #11 878 000. If it starts from that location, it will take sometime for the stream to catch
up with live block since it will need to inspect all blocks between the default start block and
current head block. Try to save and backup the cursor.txt to avoid long delays before being live
and tracking actual real-time transactions.
Flags
Use
go run ./cmd/tracker --help
To list available flags to tweak default start block, tracked addresses, status frequency and cursor file location.
