Questions? We've got answers

What is cwSOL?⌄

cwSOL is a 1:1 SOL wrapper built on Token-2022 with a confidential extension, meaning your balances are private on-chain.

How does the $100 daily spend limit work?⌄

On your first spend each day, Cnab locks $100 worth of cwSOL as collateral, opens a 70% LTV loan via Solend, and moves an equal amount into yield-bearing CETES tokens. You can then spend the resulting USDC instantly.

What happens if I don't repay?⌄

CETES yield auto-applies every 30 days. After 90 days of inactivity the protocol may liquidate CETES and, if needed, cwSOL to protect solvency.

Is Cnab audited?⌄

The smart contracts are undergoing a third-party audit. Results will be published prior to mainnet launch.
