Aile is an on-chain FX market for regional, non-USD stablecoins. You ask for a price, receive an order signed by an independent market maker, and send one transaction. The transaction delivers exactly the amount quoted or reverts. Nothing is held by Aile at any point.

How it works

The request-for-quote flow, what a firm quote is, and what happens on chain.

Quickstart

API reference

Four routes: config, levels, quote, orders.

Networks and tokens

Base mainnet. CADC, EURC, IDRX, TGBP, TRYB and XSGD against USDC.

Why this exists

Moving between a dollar stablecoin and a local-currency stablecoin on chain today means either a thin AMM pool that loses tens of basis points to size, or an off-chain desk with an account, a counterparty and a settlement delay. Aile gives integrators the third option: a firm price from a market maker that holds real inventory, settled atomically on chain, in the app they already run. Makers quote per request from inventory they hold, so a dollar of inventory is not spread across a price curve and is not bled to arbitrage as rates move. They rebalance through issuer mint-and-redeem rails and off-chain FX desks, so the cost of a fill is the cost of rebalancing plus a margin, and that cost barely grows with ticket size.

​
What Aile is

  • Non-custodial. Settlement is one atomic transaction between the taker’s wallet and the maker’s wallet on the order protocol. Funds never sit with Aile. Aile’s servers price and sign; the fill itself never passes through them.
  • RFQ, not a pool. Every price is a response to a request, for a size, for one taker. Independent market makers compete to fill it; the protocol only enforces delivery.
  • Firm quotes, no last look. A quote is a signed order. The fill executes at the signed amounts or reverts. There is no re-pricing after you commit.
  • Transparent. Every quote carries the reference mid it was priced from, and every fill is on chain.

​
What Aile is not

  • Not an on-ramp or off-ramp. Fiat stays with you and the stablecoin issuers.
  • Not a custodian. There is no deposit, no balance and no withdrawal.
  • Not a dealer. Aile owns no inventory and sets no prices. Makers do. Aile therefore promises neither rates nor depth; it shows you the capacity that exists right now in every quote.

​
Who it is for

Integrators that need a stable-to-stable FX leg and keep the ramps, compliance and the customer relationship themselves: payment orchestrators, wallets, neobanks, remittance apps and DEX aggregators. End users never see Aile; they get a better rate inside the app they already use.
