Is Blend Pools V2 Safe?
Risk Grade: B- (28/100)
Blend Pools V2 is rated as moderate risk — some novel mechanisms, generally well-understood.
Moderate risk — well-designed permissionless lending on Stellar with backstop protections, balanced by limited ecosystem liquidity and risks from uncurated pool parameters.
Blend Pools V2 is a permissionless lending protocol on the Stellar blockchain that allows anyone to create and operate lending pools with customizable parameters. With $102M in TVL and a backstop module providing first-loss protection, it serves as core DeFi infrastructure on Stellar. Its B grade reflects well-documented design and reasonable risk controls, offset by the inherent risks of permissionless pool creation and limited Stellar ecosystem liquidity.

Key Risks for Blend Pools V2 Users
Anyone can create a Blend lending pool with custom parameters. Pools with aggressive settings or exotic collateral types could expose lenders to losses if liquidations fail, though the backstop module provides a first-loss buffer.
Blend operates on Stellar, which has significantly less DeFi liquidity and composability than Ethereum. Limited liquidation venues could impair the protocol's ability to efficiently liquidate collateral during market stress.
The backstop module threshold was reduced to 100,000 in V2, lowering the barrier to pool creation. This increases accessibility but may result in pools with insufficient first-loss buffers for their risk profiles.
The reactive interest rate mechanism adjusts dynamically but could create borrower distress or lender withdrawal cascades during periods of high market volatility.
Top Risk Factors
- •Blend is a permissionless lending pool protocol on Stellar, meaning anyone can deploy a new lending pool with custom parameters. Poorly configured pools (incorrect liquidation thresholds, risky collateral types) could expose depositors to losses, though the backstop module provides a first-loss buffer.
- •The backstop module requires depositors to lock capital as a first-loss reserve for each pool. If backstop capital is insufficient during a cascade liquidation event, bad debt could be socialized to lenders in the affected pool. The backstop threshold was reduced to 100,000 in V2.
- •Blend operates on Stellar, a blockchain with significantly less DeFi ecosystem depth than Ethereum or Solana. Limited composability and liquidity venues for collateral assets could impair liquidation efficiency during stress.
- •The reactive interest rate mechanism dynamically adjusts rates to minimize idle capital. While efficient in normal conditions, aggressive rate adjustments during market stress could create borrower distress or lender withdrawal cascades.
