Book demoStablecoins move quickly. Fiat conversion does not.
Stablecoins move at internet speed. Fiat does not.
Every conversion is slowed by bank cut-offs, disconnected providers, opaque spreads, and funds trapped in accounts you do not control.
Codex gives institutions seamless fiat-to-stablecoin and stablecoin-to-fiat conversion with firm rates, local settlement, and 24/7 access.
How on/off-ramps work
Codex sits between your stablecoin balance and local bank rails. You get one counterparty, one contract, and one rate, whichever direction you're going.

FAQ
Find answers about how on/off ramp works, pricing, supported chains, and more.
An on-ramp moves local currency into stablecoins. An off-ramp moves stablecoins back into local currency. Codex handles both directions through a single counterparty, so you convert between fiat and stablecoins like USD, EUR, GBP, USDC, and USDT without stitching providers together.
The core set is USD, EUR, GBP, USDC, and USDT, with more available. Codex runs direct currency corridors across Latin America, North America, Africa, Asia, and Europe, with local settlement into markets like Hong Kong, Brazil, and Nigeria. Supported pairs grow as corridors expand, so book a demo to see the current list and the routes that fit your flow.
We support USDT and USDC across Ethereum, Tron, Solana, Polygon, Codex, Base, Optimism, Arbitrum, and Avalanche. Corridors vary by asset. Confirm your specific route with our team.
The fastest trades settle in under 30 minutes, in real time where instant rails are available. Most trades complete the same day. Actual timing depends on the corridor, the size of the trade, and the fastest rail available in that market.
Yes. Codex operates 24/7/365. Where a market has instant rails, trades settle off-hours and on weekends instead of waiting for the next banking day.
You get live two-way rates that refresh every 15 seconds. When you lock one, the exact rate is confirmed on an order confirmation before anything executes. You then have up to 12 hours to fund and settle at that rate. Quotes left unsettled void automatically.
You trade on one wholesale rate, locked when you confirm the order. Your cost is billed separately from the rate and scales with your volume. Nothing is buried in the spread, so the price you see is the price you settle at.
No. You do not park a balance with us in advance. After you lock a rate, you fund that trade directly, sending fiat to a local Codex account or stablecoins to the address we provide.
Three things. You fill at one institutional price instead of walking an order book or taking a retail quote that gets worse at size. You settle same day, and in real time on instant rails, rather than waiting on card or bank holds. And your balance never sits on a venue, so there is no exchange to hold, freeze, or fail on you. One counterparty, one rate, in and out.
Codex is built for wholesale and institutional flow, and the platform clears over 1 billion USD in monthly volume. Minimums depend on the corridor and your volume. Book a demo and we will size it to your flow.
Onboarding and compliance checks are completed before you trade, usually completed after only a few days. Book a demo to walk through what is required for your business and jurisdiction.
