Automated NFT Limit-Order System
Whale Together
A CRUD API and event-driven engine that executed automated NFT limit-orders against OpenSea listings in real time.
Whale Together needed automated limit-orders for NFTs — secure wallet handling, real-time event processing, and flexible trait filtering.
- 01
Built a CRUD API for limit-order resources with encrypted wallet data.
- 02
Integrated an event processor to execute orders as tokens were listed on OpenSea.
- 03
Added customisable trait filtering, gas presets, and expiry management.
A working automated-trading system that monitored listings and executed limit-orders in real time.
Early proof of the automation and event-driven engineering we now apply to business workflows — the same patterns, pointed at operations instead of NFTs.
