The friction

Where stablecoin top-ups hit the payments wall.

Bank top-ups exclude the crypto user.

Half your TAM holds USDT. Forcing them through a bank account is forcing them out.

Building a top-up rail is months of work.

Custody, screening, on-chain monitoring, payouts - every piece is its own project.

Compliance liability scares the legal team.

Operating a top-up flow without the right partner is a regulator's invitation.

Why SouthPay

One API, all the chains.

USDT/USDC on Ethereum, Tron, Solana, Polygon, Base - one integration, every option.

White-label and KYC-aware.

Render the flow in your product, with your brand, with your user's KYC already done.

Locked rates, instant credit.

Quote a rate, hold it for 90 seconds, credit the user's balance the moment the chain confirms.
