Bend And Proof-Of-Liquidity 🤝
Proof-of-Liquidity (PoL) is Berachain's unique consensus mechanism. This mechanism revolves around the idea that the chain's economic incentives ($BGT
) should flow to active users providing productive liquidity to the chain.
Bend, as a native Berachain dApp, aims to provide access and utility to the chain's native stablecoin $HONEY
. Bend achieves this by enabling users to earn $BGT
rewards by borrowing $HONEY
. This achieves a few objectives:
- It incentivizes users to borrow
$HONEY
and deploy it in composable DeFi strategies (e.g. leverage, yield farming, etc). - It provides a baseline yield to
$HONEY
holders, produced from the interest paid by borrowers.
How to Earn $BGT with Bend
There are a few steps involved to borrow $HONEY
and earn $BGT
, since all loans on Bend are overcollateralized. These steps are outlined below:
- Deposit collateral to Bend (e.g. WETH) - this provides a collateral balance for users to take loans out against.
- Borrow
$HONEY
- users can borrow$HONEY
against their deposited collateral. - Finally, users with
$HONEY
loans can Claim$BGT
they have earned.
Liquidation Risk
Although the most rewards are earned by borrowing maximal amounts of $HONEY
, users should carefully balance this with managing their liquidation risk
Looping Loans
$HONEY
is not enabled as a collateral asset, so it is not possible to loop $HONEY
borrows and deposits for the purpose of earning more $BGT
PoL Interactions
Those familiar with PoL may realize that earning $BGT
on Bend is different from the usual flow of depositing on BGT Station. The following diagram illustrates the unique sequence of interactions between Bend and PoL:
When borrowing $HONEY
, an equivalent amount of $vdHONEY
tokens are minted, representing the user's growing debt obligations. These two tokens are sent to users' wallets.
PoL Reward Vault
Concurrently in the borrow transaction, Periphery HONEY
tokens are minted and staked on behalf of users in a BGT reward vault, which produces $BGT
emissions dedicated to Bend borrowers. Users can Claim BGT rewards on the Bend UI.
When users repay their $HONEY
loans, their Periphery HONEY
tokens are unstaked and burned, meaning they stop earning $BGT
rewards. Any pending rewards are automatically claimed.
