Why swp.gg

Everything you need to get paid in crypto

One platform for invoices, static addresses, wallet balances, and withdrawals — with the merchant controls and API surface real payment flows need.

Hosted checkout

Create an invoice and share a /pay link. Customers pick BTC, ETH, SOL, TRX, TON, or USDT/USDC — you get a clean payment page with QR and live status.

REST API & webhooks

No SDK required. Create invoices with a Bearer key, get HMAC-signed webhooks on paid and expired, and point customers at a hosted or white-label flow.

Multi-chain stables

Native coins plus USDT and USDC across Ethereum, Tron, Solana, Base, Arbitrum, and more. Choose which networks each merchant accepts.

Static deposit addresses

Permanent per-merchant addresses for recurring top-ups — no expiry, same HD-derived custody model as invoices.

Convert & auto-convert

Swap balances between supported assets in the dashboard, or auto-convert deposits into a stable of your choice for +0.10%.

Security controls

TOTP 2FA with backup codes, withdraw IP allowlists, IP-locked API keys, payment accuracy rules, and per-coin checkout fees or discounts.

The dashboard

Run your whole operation from one screen

Monitor invoices, balances, and wallet activity. Configure accepted coins, convert to stables, and withdraw to an external address — without leaving swp.gg.

✓ Live invoices with on-chain confirmation status
✓ Multi-asset balances with convert & auto-convert
✓ Per-merchant API keys, webhooks & brand settings
✓ Payment accuracy & per-coin discount or fee
