Strengths	+ Open protocol over HTTP + Sub-cent settlement via stablecoins + Backed by Coinbase + open community	+ Combines agent identity verification (KYA) and payment authorization in one token flow + Per-agent spending limits and budget controls for buyers + Sellers can gate services on verified identity tiers and monetize APIs, MCP servers, or websites + Open KYAPay protocol underpins agent checkout and agent-to-agent transactions
Tradeoffs	− Crypto rails add operational and compliance complexity	− Both buyer and seller sides must integrate with the Skyfire network − Fee structure and pricing are not publicly documented − Younger vendor with a smaller ecosystem than Stripe or PayPal rails
