PIX and stablecoin infrastructure for PSPs and fintechs
Add PIX ↔ stablecoin collection, payout and conversion to your product — without building FX, custody and blockchain in-house.
PSPs and fintechs want to offer PIX and stablecoins to their customers without building FX, custody and blockchain infrastructure from scratch. Astron Pay delivers that layer via API, for you to embed in your product and focus on what's yours.
The challenges of building from scratch
FX and custody are expensive
Building conversion, crypto custody and blockchain integration in-house takes time, team and capital.
KYC and compliance
Operating FX and crypto assets requires identifying users and processes that must work at scale.
Scale and availability
Your product needs a foundation that handles volume and responds in seconds, 24/7.
Protecting the margin
Every outsourced layer can't eat your margin. Pricing needs to be predictable.
