Platform
A complete payments stack — from checkout to settlement. No blockchain expertise required.
Accept payments on Ethereum, Polygon, BSC, Arbitrum, and Base through a single unified API. Solana and Bitcoin coming soon.
The first crypto subscription engine that actually works. Weekly, monthly, quarterly, yearly — with automatic dunning.
Unlike other payment processors, PayChains never holds your crypto. Payments are deposited directly to addresses derived from YOUR wallet. Your keys, your crypto.
Beautiful, conversion-optimized checkout pages. Share a link or embed in your app. QR codes included.
Real-time event notifications with HMAC-SHA256 signatures, automatic retries, and exponential backoff.
Provide your wallet's extended public key (xpub) and we derive unique deposit addresses. Your private keys never leave your wallet.
Integration
Three steps from signup to accepting your first payment.
Create an account and receive live and test API keys instantly. No approval process.
One API call generates a unique deposit address, QR code, and hosted checkout page.
We monitor the blockchain, confirm transactions, and fire webhooks. Funds arrive directly in your wallet — no withdrawal needed.
