1 · Scope
Confirm the exact source chain, source asset, destination chain, destination asset, and $1–$1,000 amount.
Fastest safe test: one quote, then stop
Zero-install REST call
curl -sS https://api.assetfare.dev/v2/quote \
-H 'content-type: application/json' \
-d '{"from_chain":"solana","from_token":"SOL","to_chain":"base","to_token":"USDC","amount_usd":1}'
Signed-manifest evaluator
npx --yes --package=assetfare-mcp@0.4.0 \ assetfare-route-eval --amount 1 \ --from-chain solana --from-token SOL \ --to-chain base --to-token ETH
For Solana SOL → Base ETH, the evaluator also requests same-input Relay and Mayan snapshots. Placeholder addresses make those rows comparison-only, not executable orders.
Installable Agent Skill
npx --yes skills add odaiin/assetfare-mcp \ --skill assetfare-route -g -y
For Circle Agent Stack and other shell-capable agents. The skill teaches the agent to verify capabilities and request a fresh REST quote; it adds no signing or submission authority. Circle integration guide →
Observed economics and latency
For the exact Solana SOL → Base USDC example above, AssetFare expected receive exceeded Relay in 30/30 observations by an average 40.17 bp, with 2.07s median quote latency versus 0.50s. A post-P1 ETH-output window also led in 30/30 observations by an average 53.31 bp, with 3.69s median latency versus 0.51s. These are historical observations, not price or latency guarantees; compare fresh routes before selection. USDC evidence → · ETH method, both windows and normalized data →
What the agent should decide
2 · Safety
Require the capped public release, a valid signed manifest, and server signing/submission set to false.
3 · Economics
Compare expected receive, conservative minimum, fees, ETA, step count, and non-atomic risk with another fresh route.
4 · Stop boundary
Do not authenticate, prepare, sign, or submit unless the caller independently chooses a route and explicitly approves continuation.
Framework references
Each reviewed reference exposes capabilities and quote tools only. None can authenticate an AssetFare wallet, prepare an action, sign, submit, fund, swap, or bridge.

How the result is counted
An invited independent evaluation is recorded as an assisted external pilot, not organic demand. CI, registry probes, owner tests, audits, and canaries are never counted as customers. A genuine execution remains caller-initiated, caller-verified, caller-signed, and caller-submitted.
