What's Public on BSC
Every transaction on BSC is permanently public: sender address, recipient address, amount, timestamp, and gas fee. Anyone can see this on BSCScan. This is fundamentally different from credit card payments, which are private by default.
What Paychainly Keeps Private
- Customer identity — on-chain, you see only a wallet address, not a name or email.
- Merchant master wallet — the sweep destination is not disclosed publicly by Paychainly.
- Order details — product descriptions, customer PII, and invoice data never touch the blockchain.
Address Reuse
Paychainly generates a unique deposit address per session. After the session expires, the address is retired. This means on-chain observers can't easily link multiple purchases to the same customer, since each payment lands on a different address.
Master Wallet Exposure
All sweep transactions flow to your master wallet. A determined observer could correlate deposit addresses to your master wallet by following the sweep transactions. Mitigate this by:
- Using a separate treasury wallet for storage beyond the master address.
- Mixing funds through multiple intermediate steps (compliance permitting in your jurisdiction).
Customer Privacy Guidance
Advise customers to use a wallet they did not link to their identity (no KYC exchange withdrawal) if privacy matters to them. Hardware wallets with a fresh address offer the best privacy baseline.
GDPR Considerations
Paychainly's internal database stores email, name, and payment history. Your privacy policy must disclose this. Blockchain data cannot be deleted — design your system so sensitive data stays off-chain.
