Overview — For Fintech Service Providers

Ezys enables Fintech Service Providers to access competitive FX execution without building or managing direct relationships with multiple liquidity providers.

What Ezys Does for You

As an FSP, you submit an Intent — a declaration of what you want to exchange and under what conditions. Ezys handles the rest: sourcing quotes from a diverse network of liquidity providers, selecting the best available rate, and coordinating settlement across on-chain and off-chain rails.

You can lock a firm quote before committing to any transaction: request one, review the locked rate and fees, and execute it by submitting an Intent that references it. Nothing executes until you submit the Intent.

How It Works

Request firm Quote → Receive locked rate + quoteId → Submit Intent (quoteId attached) → Settlement

1. Request a quote — Declare the trade you want (e.g. 1,000 USDC → KRW)
2. Receive the firm quote — Ezys returns a locked rate, itemized fees, and a quoteId valid until validUntil
3. Submit the Intent — Attach the quoteId; submission is single-step and terminal (accepted or rejected), and acceptance starts execution at the locked terms
4. Settlement — Funds are settled via the optimal path (on-chain or off-chain)

You can also skip the quote and submit an Intent directly — it then competes as a best-effort auction order within the bounds you set. See the Intent Guide.
