Compatibility control
AgentCash Router 1.19.0

One discovery contract. Base stays live. Solana advances without pretending.

Keep ApexScout discoverable to AgentCash clients and prove a safe Solana static-payment contract without replacing the existing production payment stack.

Base production preservedRouter shadow conformanceSolana: Ready, not activated

What is applied

Discovery

AgentCash-first entry points

Root OpenAPI and llms.txt point agents to the same ApexScout routes and prices already in production.

Compatibility

Official Router harness

The isolated harness executes Router 1.19.0 and verifies a static route can advertise both Base and Solana without making a payment.

Settlement

No risky migration

Existing Cloudflare settlement, seller wallet, facilitator, paid routes, and prices remain unchanged.

Solana activation gate

Current state

watch-only

The code and discovery contract are ready, but Solana is not advertised as an accepted live rail without a real seller address and separate settlement proof.

Supported shape

Static exact payments

Router-backed Solana compatibility applies only to fixed-price routes. Dynamic cap and MPP session modes remain on their supported rails.

Promotion rule

Proof before claims

  • Configure a dedicated Solana seller address without exposing its secret key.
  • Enable the isolated SVM rail explicitly; do not replace Base.
  • Verify one unpaid HTTP 402 contract with Base and Solana choices.
  • Run one separately approved buyer-funded Solana paid retry.
  • Require HTTP 200 delivery, USDC settlement proof, replay protection, and rollback proof.
