Lending & Borrowing on LayerBank
How LayerBank Works
LayerBank is a decentralized money market built on an over-collateralized lending model, allowing users to:
Supply assets and earn interest
Borrow against their collateral
(Soon) Earn $ULAB rewards for participating in the market
lTokens (Interest-Bearing Tokens)
When users supply assets to LayerBank, they receive lTokens representing their share of the pool.
Initial Exchange Rate: lTokens start at 1:1 with the underlying asset (e.g., 1 USDC = 1 lUSDC).
Accrued Interest: Over time, the exchange rate increases as interest accrues (e.g., 1 USDC = 1.03 lUSDC).
Redemption: When withdrawing, users redeem lTokens for their share of the underlying asset plus accrued interest.
lTokens effectively track your position and the interest earned automatically.
Borrowing & Collateral
To open a borrow position, users enable collateral on their supplied assets.
Borrow Limit: Determined by the Max LTV (Loan-to-Value) of the collateral.
Interest Accrual: Borrowed amounts grow over time according to the Borrow APR.
Example:
Deposit 100 USDC → Receive lUSDC representing your deposit
Borrow 50 USDC → Owed amount grows as interest accrues
To close the position, repay the borrowed amount (plus interest) and withdraw remaining collateral
Risk Note: If the collateral value drops and exceeds the Max LTV threshold, the position can be partially liquidated to maintain solvency.
Dynamic Interest Rate Model
LayerBank operates in a fully on-chain, code-driven environment with no intermediaries.
Utilization-Based Rates: Borrow/Supply APRs adjust automatically according to pool utilization.
Goal: Keep liquidity healthy — higher rates at high utilization attract more suppliers and encourage debt repayment.
Result: A self-balancing money market with optimized capital efficiency.
