How Does Navi Protocol Work?
The largest lending protocol on Sui, letting you deposit crypto to earn interest, borrow, or use one-click leveraged vaults for up to 5x exposure. It manages $450M in deposits with a $38M valuation. Its B- grade reflects solid lending fundamentals, dragged down by leveraged vaults that amplify losses during downturns and thin liquidity on Sui for handling mass sell-offs.

Core Mechanisms
Lending/Collateral/Over-Collateralized
Over-collateralized lending pools with per-asset risk parameters and supply caps
Standard overcollateralized lending model similar to Aave v3. Each asset has independent collateral factor, borrow cap, and supply limit to manage risk exposure.
Lending/Interest-Rate/Kinked-Utilization
Kinked utilization curve with asset-specific parameters
Standard Aave/Compound-style kinked utilization curve. Interest rates spike above the kink point to incentivize repayment and protect withdrawal liquidity.
Lending/Liquidation/Fixed-Spread
Fixed bonus liquidation mechanism with health factor-based triggers
Liquidators receive a fixed bonus for liquidating underwater positions. Health factor must drop below 1.0 to trigger liquidation.
Yield/Leveraged-Vault
NovelAutomatic Leverage Vaults for one-click leveraged yield strategies on LSTs and LP tokens
Novel automated leverage mechanism that borrows low-APR assets and deploys into high-yield strategies like LSTs. Allows 3-5x leverage on yield-bearing assets, amplifying both returns and liquidation risk.
Liquid-Staking/Reward-Bearing-LST
Volo SUI liquid staking with reward-bearing LST
Volo provides liquid staking for SUI, issuing a reward-bearing LST. Integrated into NAVI's lending markets as collateral, creating dependency between staking and lending risk.
DEX/Aggregator
Astros: integrated DEX aggregator for cross-chain swaps
Astros provides DEX aggregation and cross-chain swap functionality within the NAVI ecosystem. Sources liquidity from multiple Sui DEXs for best execution.
Oracle/External
Decentralized oracle infrastructure for price feeds across lending markets
NAVI uses decentralized oracle infrastructure for reliable price feeds. Newer Sui-native assets may have limited oracle coverage and price source depth.
Governance/Token
NAVX governance token with ecosystem fund and Jump Trading market-making support
NAVX token provides governance over protocol parameters. 10M NAVX allocated to ecosystem fund. Binance Alpha listing with $80M Jump Trading market-making support in May 2025.
How the Pieces Interact
Leveraged vault positions amplify liquidation cascades: a 30% SUI decline creates 90-150% losses on 3-5x leveraged positions, flooding liquidation markets with sell pressure that triggers second-wave liquidations on standard positions.
Volo LST depeg directly impairs collateral value across NAVI lending markets. Since Volo LST is used as both collateral and in leveraged vault strategies, a depeg creates amplified, correlated losses.
Mass unwinding of leveraged positions requires selling into Sui DEXs. Insufficient DEX liquidity means large slippage during unwinds, worsening liquidation outcomes and increasing bad debt.
Cross-chain asset pricing depends on bridge and oracle reliability. Discrepancies between cross-chain oracle prices and actual market prices can create arbitrage opportunities that drain lending pools.
Supply cap and risk parameter governance is controlled by NAVX holders. With low FDV ($38M) and Jump Trading market-making, governance capture is relatively cheap compared to protocol TVL ($450M).
What Could Go Wrong
- Automatic Leverage Vaults amplify liquidation risk during market downturns, creating protocol-level bad debt exposure
- Volo liquid staking token depeg risk creates correlated collateral exposure across NAVI lending markets
- Single-chain concentration on Sui with limited DeFi infrastructure maturity and thin DEX liquidity for liquidations
Leveraged Vault Liquidation Cascade
ModerateTrigger: A sharp decline in SUI or LST prices triggers mass liquidations of NAVI's Automatic Leverage Vaults, creating a cascading liquidation spiral across the protocol
- 1.SUI price drops >30%, pushing leveraged vault positions below liquidation thresholds — Automatic Leverage Vaults with 3-5x exposure face immediate margin calls across multiple positions simultaneously
- 2.Mass unwinding of leveraged positions floods Sui DEXs with sell pressure — SUI and LST prices drop further as leveraged unwinds create selling feedback loops
- 3.Standard lending positions collateralized by SUI also hit liquidation thresholds — Second wave of liquidations overwhelms available liquidity; bad debt begins accumulating
- 4.Depositors race to withdraw, spiking utilization to 100% — Withdrawal liquidity dries up; remaining depositors absorb bad debt losses
