Liquidity Pools

Contrary to the inefficient Peer-To-Peer model, the Unlockd liquidity model relies on Liquidity Pools.

Users contribute their assets to a large pool of liquidity called the Lending Pool. This pool is available for borrowers to borrow from, and lenders share in the interest that borrowers pay back to the pool.

Benefits of Liquidity Pools

The primary advantage of utilizing Liquidity Pools is the immediate availability of funds for borrowers. Unlike traditional Peer-to-Peer lending, which requires matching individual lenders with borrowers, Liquidity Pools allow for instant borrowing without the wait, streamlining the loan process significantly.

uTokens

One of the advanced features of the lending pool contract is the tokenization of the lending position.

When users deposit assets, they receive a corresponding amount of uTokens (uETH in the case of providing liquidity in the form of ETH, uUSDC for the stablecoins pool). All interest collected by the Borrowing Interest Rates model is distributed to uToken holders directly by continuously increasing their wallet balance.

uTokens are the interest-bearing ERC-20 tokens that map the liquidity deposited and accrue interest based on the underlying deposited asset (ETH or USDC), with a 1:1 ratio.

uTokens are minted upon deposit. Their value increases until they are burned on redemption (withdrawing the liquidity from the Lending Pool).

uTokens can be safely stored, transferred, or traded, and redeemed for their underlying assets at any time.

Deposit APY

uTokens holders receive continuous earnings that evolve with market conditions.

uTokens holders share the interests paid by borrowers. The borrow interest rates paid are distributed as yield for uTokens holders who have deposited in the protocol, excluding a share of yields sent to the ecosystem reserve defined by the reserve factor. This interest rate is paid on the capital lent out and then shared among all the liquidity providers.

The deposit APY, $D_t$, is:

$D_t = U_t * B_t * (1-R_t)$.

$U_t$: the utilisation ratio.

$B_t$: the variable borrow rate.

$R_t$: the reserve factor.

2 Isolated Pools

Unlockd is designed to cater to a diverse range of needs within the digital asset space, which is why we maintain two distinct Liquidity Pools: one for WETH (Wrapped Ethereum) and another for USDC (USD Coin).

Each pool is tailored to support different types of collateral and lending scenarios.

The WETH pool primarily facilitates loans against digital assets like gaming items, PFP NFTs, token streams, and a broad spectrum of other NFTs.

The USDC pool is reserved for loans against tokenized Real World Assets (RWAs) and token streams as well.

Both pools operate under the same high standards of security and efficiency, ensuring that all users have access to flexible and instant borrowing options. Detailed information about each pool and their specific features can be found in the dedicated sections:
