--Why Flashnet

The liquidity rails Bitcoin was meant to have

Native Bitcoin trading infra with institutional-grade performance and absolute self-custody.

Native, not wrapped

Trade pure Bitcoin & native assets - no bridges, no custody risk.

Self-custody by design

Keys stay client-side; validators only witness intent and sign off on settlement.

CEX-grade throughput

Sub-second matching and dirty-cheap fees via Spark & TEEs - no mempool congestion.

API-first architecture

REST, WebSocket, & SDKs get you live in minutes.

Trade anything

Flashnet is the engine, you own the experience.
