Save

Save is the rebranded and expanded form of Solend, the protocol that pioneered decentralized lending on Solana. Launched in November 2021, Solend raised seed funding from Dragonfly Ventures, Polychain Capital, Coinbase Ventures, and Solana Ventures, then scaled to become the largest DeFi application on the network by total value locked. In July 2024, the team relaunched under the Save name with a widened product suite, repositioning the protocol from a single-purpose lending market into what it describes as Solana's permissionless savings account.

From Solend to Save

Solend's early trajectory was steep. By March 2022 it became the first Solana DeFi protocol to surpass one billion dollars in total value locked, a milestone that reflected both the network's rapid growth and the demand for on-chain credit markets. The protocol's smart contract, deployed at contract address So1endDq2YkqhipRh3WViPa8hdiSpxWy6z3Z6tMCpAo, survived some of the most turbulent events in crypto history: the collapse of the UST stablecoin, the cascading failures of Three Arrows Capital, a USDH oracle manipulation attack, and the FTX implosion in late 2022. That last event hit the Solana ecosystem particularly hard, triggering liquidation cascades across DeFi that substantially reduced Solend's TVL.

Recovery was gradual. Between 2023 and 2024, competitors including Kamino Finance and MarginFi captured much of the market share Solend had previously held. The team responded not with a feature patch but with a comprehensive rebrand, announcing on July 24, 2024 that Solend was becoming Save and expanding into three adjacent product categories.

Core Lending Mechanics

Save runs an algorithmic, decentralized lending and borrowing protocol that operates entirely on Solana. Users deposit assets into pools and earn variable interest rates determined by utilization. Borrowers post collateral above a minimum ratio and draw liquidity against it. Liquidations are permissionless: any external actor can repay an undercollateralized loan and claim the collateral at a discount, keeping the system solvent without relying on a centralized liquidator.

The protocol uses an isolated pool structure. Each pool operates as a self-contained risk environment, which means a compromised oracle or a listing that turns out to be illiquid on a long-tail pool cannot cascade into the main market. This architecture lets Save offer permissionless pools for assets that more conservative protocols will not list, while protecting depositors in core markets from contagion. The main pool covers blue-chip Solana assets including SOL, USDC, and USDT alongside major liquid staking tokens such as mSOL and JitoSOL.

New Product Suite

The July 2024 rebrand introduced three additions alongside the existing lending markets.

saveSOL is a liquid staking token representing staked SOL. Holders earn staking yield while retaining the ability to use saveSOL as collateral within the protocol. The design follows the standard liquid staking model common across Solana, but native integration with Save's borrow markets gives users a direct path to leverage their staked position without leaving the protocol.

SUSD is a native decentralized stablecoin backed by SOL collateral. The headline feature is zero-percent interest borrowing: users who lock SOL can mint SUSD at no ongoing interest cost, which the team positioned as significantly cheaper than centralized lending alternatives that charged around ten percent APR on similar positions at the time of launch. SUSD uses saveSOL as collateral, creating a flywheel between liquid staking and stablecoin issuance within the Save ecosystem.

dumpy.fun is a purpose-built platform for shorting Solana memecoins. Users who hold memecoin positions deposit them into the platform and earn lending fees. Traders who want short exposure borrow those coins and profit if prices fall. The protocol verifies liquidation prices on-chain through a companion tool called squeezy.lol. The design is fully on-chain, distinguishing it from perpetuals-based short mechanisms that rely on off-chain matching.

Scale and Market Position

At the time of the rebrand announcement in July 2024, Save held approximately 395 million dollars in total deposits and 92.9 million dollars in outstanding borrows, a significant recovery from the FTX-era lows but still below the 2022 peak. By December 2025, independent data sources placed TVL at roughly 300 million dollars. Protocol TVL has continued to face pressure from newer entrants, with Kamino and Jupiter Lend growing rapidly on the back of their own integrated DeFi suites.

Save also expanded beyond Solana during this period. In March 2024, the team launched Suilend on the Sui blockchain, demonstrating a multi-chain development strategy even as the core protocol underwent rebranding.

Relevance Within the Solana Ecosystem

Save occupies a distinctive niche as Solana's original production lending protocol. It carries the track record of operating continuously through some of the most stressful conditions the network has faced, a credential newer protocols cannot match. The permissionless isolated pool model means it can serve assets and use cases that risk-averse competitors decline, giving it a long-tail lending function the broader ecosystem relies on even as headline TVL trails the leaders.

The protocol remains live and actively maintained. The Save X account posts regularly as Save (formerly Solend), and the save.finance interface serves lenders, borrowers, and liquidity providers across Solana's major assets. Whether the expanded product suite, particularly saveSOL and SUSD, generates the user growth the team is targeting remains an open question, but Save enters 2026 as one of the most proven protocols in Solana DeFi by longevity and resilience.
