AssetFare implements a non-custodial route from SOL on Solana to native ETH on Arbitrum. The route is available but not currently price-recommended. The page also preserves historical design and canary evidence.
The historical direct_route_summary used ordered Raydium, Circle CCTP, and Uniswap provider steps with normalized chain:asset endpoints, exact amount bounds, and the AssetFare fee step. Every current public route is direct_protocol_only; external_intent remains only as a compatibility enum. route_aggregator_used=false describes only AssetFare's engine.
The public quote API returns solana:SOL→arbitrum:ETH with price_recommended_for_amount=false. The route measured worse than competitors through the tested $10,000 ceiling and has no current best-from claim. This is advisory and does not add another execution field.
The composition uses a caller-signed direct Raydium CLMM SOL→USDC swap, Circle CCTP transfer, and caller-signed direct Uniswap v3 USDC→ETH swap. It uses the same strict quote selection and unsigned-plan flow as every other route.
See the historical original-corridor $250 canary, current v2 agent guide, and OpenAPI v2. The historical canary verifies an earlier execution design, not the current v2 execution architecture.
