Verifiable caller-owned mainnet canaries and deployed execution evidence for the current nineteen-chain release, plus clearly labeled historical paths. These owner tests prove technical paths, not customer demand, current price superiority or performance guarantees.
100-route × eight-amount read-only audit · 2026-10-25
All 800 AssetFare route/amount cells materialized and returned an AssetFare quote. Across the measured provider set, 386 cells had a verified external winner, 65 had a verified AssetFare winner, and 349 remained unresolved because competitor evidence was incomplete, unavailable, or access-blocked. The permitted conclusion is only “best among measured, complete, fresh candidates”; full-market optimality was not established and the audit did not automatically replace the dated public recommendation policy.
Machine-readable audit summary · Published route-economics policy
Unichain and Ink source-only corridors
The ownerless exact-1bp CCTP executor is deployed and pinned on both chains. Caller-owned canaries completed from each source to Solana; these owner tests are technical validation, not customer demand or a cheapest-price claim.
Machine-readable release evidence · reproducible public source and artifact
Twelve public-expansion canaries
Monad, Avalanche, Cronos, Injective, Linea and Aptos were each verified to both Base and Solana before public activation. The machine record publishes source and destination transaction hashes, exact input/minimum/actual output, two-RPC observers, deployment identities and consumed authorization counts. It excludes raw transactions and private material.
Ethereum and HyperEVM expansion executors
The same deterministic ownerless exact-1bp CCTP V2 executor address is deployed on both chains: 0xF17133D57Ad0E160F7D71876582a2B814feE3E79. Runtime code and constructor immutables are independently pinned per chain.

V2 has no economic amount floor. It keeps exact-1bp fee arithmetic, a 5-USDC absolute CCTP fee cap, fixed source domains and destinations, zero retained allowance/balance, and no owner, upgrade, rescue, signing, or submission surface. Route economics are separately published as non-enforcing guidance.
Historical caller-owned agent journey · MCP/npm 1.8.4
An autonomous caller evaluated a quote, selected exact bounds, created a receipt-driven session and used its own local wallet adapter. AssetFare received no key, signed nothing and submitted nothing. Polygon is now available without a current price recommendation; its transaction below remains historical technical evidence only, not a current price claim.
Every source and destination receipt reached two-RPC finalized agreement before its session became complete. The caller runner retained confirmed hashes across observation delays and never re-submitted a completed step.

Historical paired route dataset: 30 observations
The retained Solana SOL → Base ETH dataset records same-input outputs and latency at $250, $500 and $1,000. It is engineering evidence from one past window, not a current price-superiority claim. Requote every route before selection.

Historical agent-payment dataset: 30 observations
The retained Solana SOL → Base USDC dataset records same-input output, latency, one 429, and one fail-closed 502 from one past window. It is not a current price-superiority claim.
Read the Base and Arbitrum case studies. Agents can independently check all twelve Solidity sources, twenty-two deployment receipts, and the pinned Aptos Move script, plus exact runtime code, fee and noncustody policies, and disclosed limitations in the canonical safety evidence bundle, then verify its SHA-256 in the Ed25519-signed manifest.
