SuiLend
A lending and borrowing protocol running on the Sui blockchain. The SuiLend platform went live in early 2024 and has since grown to over $160M in total deposits across the Main Market alone.
Mission
SuiLend exists to make capital more productive. Not through speculation — through real, on-chain lending markets where rates are transparent and liquidations happen by code, not by back-room decisions.
The protocol was built to serve depositors who want yield and borrowers who need liquidity, without either side needing to trust the other. That's what smart contracts are for. The SuiLend platform handles the accounting, the interest accrual, and the collateral enforcement — all on-chain, all auditable.
Open access matters. Anyone with a Sui wallet can interact with SuiLend's protocol directly.
Technology
SuiLend is written in Move — Sui's native smart contract language. Move's resource model makes certain classes of bugs impossible at the language level. That's not marketing. It's a structural property of how the runtime handles assets.
The protocol supports multiple isolated markets. The Main Market handles assets like SUI, USDC, suiUSDT, WBTC, and LBTC. Specialized markets — Ember Market, Matrixdock Gold Market, Bucket Market — serve specific asset classes with their own risk parameters.
Smart Contracts
Move-based contracts on Sui. Deterministic execution, no re-entrancy, object-level ownership enforced by the VM.
Interest Rate Model
Utilization-based rates that update automatically. Borrowers pay more when liquidity is tight; depositors earn more as a result.
Liquidation Engine
Collateral ratios enforced on-chain. Positions falling below health thresholds are liquidated without human intervention.
Oracle Integration
Price feeds sourced from on-chain oracles. LTV ratios and borrow weights are calibrated per-asset based on volatility profiles.
Approach to Risk
Every asset listed on SuiLend goes through a risk review. LTV ratios, borrow weight multipliers, deposit caps, and borrow caps are set deliberately — not generously.
Isolated assets are kept separate from the main collateral pool. If something goes wrong with a small, illiquid token, the damage stays contained. It's a design choice, not an accident. The protocol has an explicit "Isolated assets" category for this reason, covering tokens like HAEDAL, BLUE, and NS.
Deprecated assets are tracked and displayed. Transparency about what's being wound down is part of how SuiLend's protocol maintains user trust. Visit the questions page for more detail on how risk tiers work.

Ecosystem
SuiLend doesn't operate in isolation. The protocol connects with SpringSui for liquid staking, STEAMM for AMM liquidity, and a range of ecosystem LSTs — kSUI, stratSUI, oshiSUI, iSUI, mSUI, and more. These integrations increase the utility of deposited assets.
The SEND token ties the ecosystem together. Holders participate in governance, earn protocol rewards, and gain access to the SEND money app at send.suilend.fi.
Bridge support via Wormhole and Sui Bridge means assets from other chains — suiETH, suiWBTC, SOL — can be deposited directly. The protocol meets assets where they already are rather than asking users to work around it. You can explore the full market at sui-lend.net.
The Team
The team behind SuiLend has been building on Sui since near the beginning. That history matters — they've seen the network evolve, adapted the protocol through multiple upgrade cycles, and shipped features in response to how actual users interact with the markets.
There's no large headcount to brag about. A focused group of engineers, risk analysts, and protocol designers built what you see in the markets today. The code is the output. The TVL is the vote of confidence.
Questions, feedback, and bug reports go to Discord. The team monitors it.
