Introduction

Contractor is the service responsible for downloading SmartWeave contracts from Arweave and saving them to a Postgres database. It constantly monitors the Arweave network for new blocks, downloads transactions, parses contracts and saves them to the database.

Run​

# Start from the latest saved block
./syncer contract

# Overwrite contracts within a block range and stop
./syncer contract --start=1237269 --stop=1237269 --DANGEROUS_replace_existing_data

Internals​

Here are some details about how the Contractor works internally. Each box in the diagram is a separate Task that may spawn multiple goroutines, everything is set up in src/contract/controller.go.
