Escrow-first. Fiat stays local.

  1. 01

    Quote

    Request a fixed all-in quote by country, side, rail and amount. Valid for 5 minutes.

  2. 02

    Lock

    Kalea matches an independent local liquidity partner and locks the stablecoins in escrow.

  3. 03

    Pay locally

    Fiat moves over Pix, SPEI, Yape, QR Simple or bank transfer, between your user and the partner.

  4. 04

    Release

    On confirmation the escrow releases the stablecoins. Your fee comes from your prefunded balance.

Safety

  • Fiat never touches Kalea.
  • Every order gets its own escrow with fixed amounts.
  • Disputes freeze the escrow; an insurance fund covers resolved losses.

Testnet today: the Soroban escrow contract is deployed, and the API still runs the order lifecycle as a simulation while it is wired in.

Live quote

FAQ

Questions, answered.

Businesses

Who is Kalea for?

Businesses that want local on-ramps, off-ramps or QR payments in their product: wallets, exchanges, fintechs, payment apps, marketplaces and platforms. Kalea does not serve consumers directly.

Which networks and stablecoins do you support?

Today, USDC on the Stellar testnet. Kalea is built to support USDC and USDT across EVM networks (Ethereum, Base, Polygon, Arbitrum, BNB Chain) and non-EVM networks (Solana, Tron); those are next.

Which countries are covered?

Bolivia, Brazil, Peru and Mexico have demo pricing on testnet. Argentina, Colombia, Chile and Ecuador are planned.

Does Kalea hold my users' money?

Kalea never holds local fiat; it moves over local rails between your end user and an independent local liquidity partner. Stablecoins are held by a per-order escrow until the order is released, refunded or resolved.

Can I use Kalea with real funds today?

Not yet. Kalea runs on testnet with demo pricing. Licensing requirements will be assessed per country before operating with real funds.

Developers

How do I integrate?

Your backend calls the REST API with an API key: list corridors, request a quote, create an order and follow it to release. The public demo quote endpoint needs no key.

Can I accept QR payments?

Yes. A QR payment is an off-ramp variant: create a sell order with kind qr_payment and the QR payload. Your end user locks stablecoins and the third-party QR is paid in local currency.

Do you offer webhooks or an SDK?

Not yet; both are next. Today you read an order's status from the orders endpoint.
