Privacy Features
How Cylend protects your financial privacy using Sapphire confidential computing
The Privacy Problem
Traditional DeFi lending exposes everything on-chain: positions, amounts, strategies. Cylend solves this using Oasis Sapphire's confidential computing.
What's Private vs Public
Private (Encrypted)
- • Action amounts and tokens
- • Collateral positions
- • Borrow amounts
- • Health factors
- • Counterparty information
Public (On-Chain)
- • Deposit creation events
- • Encrypted action hashes
- • Fund release events
- • Total pool liquidity
How It Works
1
Client-Side Encryption
Actions encrypted in your browser using Sapphire's public key before leaving.
2
TEE Processing
Sapphire decrypts and processes actions in a Trusted Execution Environment.
3
Observable Settlement
Only fund releases are visible on Mantle - details remain hidden.
Important
Mantle only sees encrypted hashes. The actual lending logic runs on Sapphire where data is decrypted inside secure hardware enclaves.
