⚙️ How It Works

Product Architecture

Your Bitcoin is locked in secure vaults — either through multi-signature setups or with your preferred custody provider. CoUSD is then minted against this collateral and can be freely deployed across DeFi and CeFi platforms.

Vault Types

• No-Liquidation Vault

  Lock your BTC for a fixed term. There's no risk of liquidation — repayment is automated at maturity. Ideal for users seeking stability and predictability.

• Liquidatable Vault

  Offers flexibility with no fixed term, but your position is subject to real-time loan-to-value (LTV) monitoring. Falling below minimum collateral ratios may trigger liquidation.

Collateral & LTV (Loan-to-Value) Ratio

Your borrowing power is determined by your LTV ratio. To protect your position and avoid liquidation (in liquidatable vaults), it's important to maintain a healthy collateral buffer — especially in volatile markets.

Security & Custody

Coffer leverages a hybrid custody model:

• On-chain Multi-Signature for transparent, trust-minimized security.
• Regulated Custodians for optional institutional-grade compliance and operational flexibility.

All vaults are auditable and designed for both self-sovereign users and enterprise-grade participants.
