Trust Center
Gryllex is a custodial exchange that sits on Yellow Card for crypto and S3P for bills. We are privacy-respecting, not anonymous — every movement is on our ledger because that protects you and meets AML obligations.
Partner vaults
USDT, BTC, and ETH live in Yellow Card vaults. Gryllex does not store private keys or HD seeds.
Gates you control
TOTP 2FA, wallet PIN, and httpOnly session cookies. Withdrawals require a verified identity.
Progressive compliance
Email and phone to open an account. Identity documents when you need crypto rails or higher limits.
Visible pricing
Provider fees and spread are shown at quote time. Internal XAF transfers are free.
What we check
- Email and phone at signup
- Identity documents when you request higher tiers or crypto activity
- Sanctions and fraud screening on signup and large withdrawals (where integrated)
- Velocity and amount-based risk scoring on outbound transfers
Starting without ID
After email and phone, you can use S3P bills, airtime, and XAF cash-in within product rules. Crypto buy, sell, deposit, and on-chain withdraw require a verified identity. Exact caps are shown in-app.
