Agent Payment Rails.

The agent economy needs payments. Identity gets bundled in. Whoever wins this layer issues every agent.

Thesis

Why this sector, why now.

Agent payment infrastructure (Skyfire, Nava, others) is the most under-priced category on Lookout. Agents transacting at scale will not stay on Visa rails — interchange economics break, fraud detection misfires. A crypto-native rail wins by default, but the interesting question is whether the wedge is payments (Visa-equivalent for agents) or identity (CA-equivalent for agents). I covered the Skyfire vs Nava fork in the first POV piece — identity-at-issuance vs identity-at-verification. My current read is issuance is winner-take-most.

Signals I track

What would move my read.

  1. 01

    Protocols accepting Skyfire-signed credentials natively

  2. 02

    Real agent transaction volume (not test wallets)

  3. 03

    Regulatory framing — whether Treasury / OCC writes attestable-identity rules

Kill shot

What would kill the thesis

Stablecoin issuers (Circle, Tether, PYUSD) ship native agent rails directly and skip the identity-issuer middleware layer entirely.

Agent Payment Rails: Skyfire vs Nava and the Fork Ahead

Two payment infrastructures for autonomous agents. One has a16z and Coinbase. The other has Polychain. Both are betting on different layers — and only one of those layers is going to matter when the agent economy hits scale.
