Argentina
ARS ($)
Argentina pairs high stablecoin demand with instant CVU bank transfers. Koywe and Manteca ramp Argentine pesos to USDC on Stellar with local payment rails (CVU/CBU/alias, QR) and competitive FX.

CVU / CBU / alias
Argentine immediate bank transfer addressed by CVU, CBU, or alias — Manteca’s ARS rail.

QR-code based interbank transfer in Argentina, completed in the user’s banking app.
otherAbout the Local Asset
Unlike USD-intermediated flows that require multiple conversion steps, locally denominated assets on Stellar enable direct on- and off-ramps between ARS and the blockchain. This means fewer intermediaries, lower fees, and faster settlement.
Yield-bearing assets like stablebonds take this a step further by backing each token with local government treasury instruments, which generates yield that can be passed on as lower conversion costs — often below 25 basis points.
The result: cheaper, easier, and quicker access to on- and off-chain value for both developers building services and the end users they serve.

We evaluate providers against two lenses — a commercial bar (real local value for end-users) and a developer bar (can you actually build on it):
Commercial
- Locally denominated asset (stablecoin or stablebond) on Stellar
- Support for local payment rails connected to Stellar
- Competitive rates (wholesale <25 bps conversion)
- Deep liquidity for low slippage (local ↔ global assets)
Developer
- Open self-service access (credentials + sandbox, no human in the loop)
- Accurate, well-documented API (docs match the wire)
- High-fidelity sandbox (a completed test ramp lands real on-chain testnet tokens)
- Agent-buildable (machine-readable docs/spec, diagnosable failures)
- Fee/rate discoverability (costs findable via pricing docs or a quote/fee API)
