StableRoute
The easiest way to find cheapest/fastest way to move stablecoins with an honest, per-leg breakdown of where the fee actually goes.

Description
StableRoute finds the cheapest way to move money across borders with stablecoins. Give it corridor amount, source currency, destination currency and it returns every viable stablecoin-and-chain route ranked by total landed cost: on-ramp fee, network cost, off-ramp fee, and FX spread, along with the amount your recipient actually receives and the expected settlement time. It covers ten currency corridors across seven chains, and every figure is flagged live, cached, or estimated so you always know what you're trusting. Built for treasury teams, payment operators, and anyone comparing cross-border rails. Two tools: compare_routes and list_corridors.
Estimates for comparison only — not financial advice.
Progress During Hackathon
<p>I picked the Finance Copilot track and built StableRoute, an A2MCP agent that answers a question everyone in crypto payments assumes but nobody actually shows: stablecoins are supposedly cheap for cross-border transfers — but what's the real all-in cost, and which route wins?</p><p>I designed a landed-cost model that decomposes a transfer into its four real cost legs — on-ramp, network/gas, off-ramp, and FX spread — and ranks every stablecoin-and-chain combination by total cost or by settlement speed. It's built in Python with FastAPI and FastMCP, exposing two tools (<code data-inline="true" spellcheck="false">compare_routes</code>, <code data-inline="true" spellcheck="false">list_corridors</code>), and now covers ten currency corridors across seven chains. Live FX comes from a real feed with a graceful fallback; the USD→MXN off-ramp uses Bitso's published exchange fees; and there's an optional live on-chain gas hook.</p><p>The thing I care about most is honesty: because this outputs money-movement numbers, every figure is labelled live, cached, or estimated with a timestamp, so the agent never fakes precision. The model also surfaced a genuinely useful finding — the on/off-ramps are ~99% of the cost while the chain barely moves the number, which flips the usual "which chain is cheapest" question on its head.</p><p>I deployed it to a public HTTPS endpoint, added a landing page and health check, and verified the MCP handshake end to end. I also built a companion browser UI running the same model so the fee breakdown is visible at a glance for the demo.</p><p>Next: replace the estimated ramp fees with live provider quotes so the "estimated" flags disappear and StableRoute becomes a true best-execution comparator rather than a cost model.</p><p>A couple of notes: the progress piece runs long enough for a detailed submission field but I can cut it to a tight 3–4 sentences if the form is short, and I've kept it strictly truthful — no invented users or sales, since it's a fresh listing. If you want, I can also spin the progress into a first-person HackQuest builder-journey update in your structured LinkedIn style, or trim the description to a hard character limit if OKX imposes one. Which format do you need it in?</p>
