About Coinnect

The open routing layer for global money

Coinnect is an open money transfer routing engine. It finds the cheapest path to send money between any two currencies — fiat, crypto, or P2P — by comparing 80+ adapters worldwide in real time. Think of it as the plumbing layer that maps every money rail on the internet, so anyone can find the best route.

The Google Maps of money transfers. Google Maps doesn't own the roads — it maps them, and lets you find the fastest route. Coinnect doesn't move money — it maps every corridor, exchange, and fee, so you always know the cheapest path. The routing data is open. Products get built on top.

Part of the ceiba.to network

Coinnect is a node in the ceiba.to network — a fractal community protocol where tools, data, and governance are shared across independent projects. The routing data Coinnect produces feeds other ceiba nodes, and ceiba nodes contribute adapters and verification data back.


Vision

Moving money across borders is still opaque. Fees are hidden. Routes are locked behind proprietary platforms. People in the Global South — migrant workers, freelancers, small businesses — pay the highest costs because they have the fewest options visible to them.

Coinnect exists to make every money rail on the internet visible and comparable. The routing data should be open infrastructure, like road maps. When the map is open, anyone can build navigation on top — fintech apps, AI agents, community tools, remittance advisors.

The end state: you never overpay to move money, because every path is mapped and every fee is transparent.


How Coinnect is sustained

Free for humans

The website and basic API access are free forever. No signup, no ads, no affiliate fees.

x402 agent payments

AI agents and bots pay $0.002 USDC per request via x402 on Base L2. This is the primary revenue model.

API tiers

Commercial API keys for high-volume users. Free tier is generous (1,000 req/day).

Donations

Community donations via USDC, BTC Lightning, or ETH. Every donation keeps the lights on.


Built by KOA Labs

Coinnect is built and maintained by KOA Labs, a small studio focused on open infrastructure tools. KOA Labs also builds community protocols, data pipelines, and AI agent tooling.
