Building a Bitcoin Lightning Payment Gateway – What Should You Focus On?

If you're working on a Lightning payment gateway, speed and low fees are obvious but implementation is where it gets tricky.

Key considerations:

• Liquidity (inbound/outbound channels)
• Routing reliability across the network
• Custodial vs non-custodial approach
• BTC vs fiat settlement strategy
• API + webhook design for integrations

Lightning works well in theory, but these factors decide real-world performance.
