Stellar DeFi and dApps, mapped

Stellar DeFi is the network’s toolkit for trading, lending and earning yield, and it is unusual in one respect: much of it is built into the protocol itself. Stellar has a native order-book exchange, native AMM liquidity pools and path payments that route across both, all without smart contracts. Since Soroban went live in 2024, a second layer of Stellar dApps has grown on top, led by the Blend lending protocol and the Aquarius AMM.

How big is it? DefiLlama counted about $226M in total value locked (TVL) on Stellar at our latest check. The 2026 high, which is also the peak of DefiLlama’s Stellar series, was $272.8M on 1 October 2026 (DefiLlama). That is small next to Ethereum or Solana, but it is real money, and it brings real risks. Stellar DeFi suffered a roughly $10M oracle exploit in February 2026. This guide maps the main protocols, explains how they work, and shows how to start without getting burned.

How Stellar DeFi differs: trading built into the protocol

On most chains, a DEX is a smart contract someone deployed. On Stellar, the basic trading layer belongs to the ledger itself. Offers to buy and sell assets are ledger entries created with the ManageBuyOffer and ManageSellOffer operations, and the network matches them (SDF list of operations). AMM pools are ledger entries too. Because this logic runs inside Stellar Core, there is no third-party contract to audit, upgrade or exploit at that layer.

The trade-off is flexibility. Built-in features do one job and change only through validator-approved protocol upgrades. Anything more creative, such as lending, concentrated liquidity, vaults or stablecoin minting, needs Soroban smart contracts. Today’s Stellar DeFi is a mix of both layers, and good apps use both. A swap might route through a native pool, a Soroban AMM and the order book in one go.

There is one more structural difference: every token on Stellar is an issued asset that you opt into with a trustline. That adds a step, and each trustline locks 0.5 XLM in reserve, but it also means a classic asset only lands in your account once you have explicitly agreed to hold it. Our glossary explains trustlines and reserves in more detail.

The Stellar DEX and path payments

The native Stellar DEX (often called the SDEX) is an order book that works between any pair of Stellar assets, for example XLM/USDC or USDC/EURC. You can place limit orders directly from wallets that support it, or through dedicated front ends. StellarX and StellarTerm, both operated by Ultra Stellar (the company behind LOBSTR), were still online at our latest check, and we found no shutdown notice for either.

Path payments are where the built-in design shines. With a strict-send payment you send a fixed amount and the recipient gets at least a minimum. With strict-receive the recipient gets an exact amount and you cap what you spend. Either way, the protocol can route through intermediate assets, combining order books and pools in a single atomic operation. A worker in Seoul could send XLM while a relative in Manila receives USDC, with the conversion handled in one transaction. Whether a cash-out exists at the far end depends on local anchors and fiat ramps.

DefiLlama tracks the SDEX itself at about $14M in liquidity, a reminder that order-book depth on many pairs is thin. That is a quiet risk in its own right, as the YieldBlox case later showed.

Native AMM liquidity pools (CAP-38)

Protocol 18 added automated market maker pools to Stellar on 3 November 2021 (SDF announcement). SDF describes Stellar as the first layer-1 with AMMs built into the protocol; that is SDF’s own claim. The pools use the familiar constant-product formula, and CAP-38 fixes the fee at 0.3%, paid by traders to liquidity providers (CAP-38).

Providing liquidity is a real yield source, but not a free one. You earn a share of fees, and in exchange you take on impermanent loss: if one asset’s price moves sharply against the other, you can end up with less value than if you had simply held both. DefiLlama shows the native pools at about $8M in TVL, much less than the Soroban-based AMMs. For yield options more broadly, see our XLM staking and earning guide. Spoiler: XLM has no native staking.

Lending on Stellar: Blend

Blend is the heavyweight of Stellar DeFi. Built by Script3, it calls itself “a liquidity protocol primitive” (Blend docs). Anyone can create a lending pool with its own assets, oracle and parameters, and lenders earn interest paid by borrowers plus BLND token emissions. DefiLlama showed Blend Pools V2 at about $129M at our latest check, more than half of all Stellar DeFi TVL. Blend V2 went through a Certora audit competition in February 2025.

The safety mechanism is the backstop. Each pool has its own backstop module where depositors lock BLND:USDC 80:20 liquidity tokens. They act as first-loss capital: if a borrower’s position turns into bad debt, the backstop pays it off before lenders take a hit. In return, backstop depositors earn a share of interest, and withdrawals sit in a 17-day queue so the buffer cannot flee overnight (Blend backstop docs).

The flip side of permissionless pools is that quality varies. Two Blend pools can have very different oracles, collateral and risk settings. The protocol core can be sound while a single pool is badly configured, which is exactly what happened in February 2026.

AMMs, swaps and other Stellar dApps on Soroban

Aquarius is the largest Soroban DEX, at about $38M in TVL on DefiLlama. It runs an AMM with stable and volatile pools. Holders lock its AQUA token to get ICE, then use ICE to vote on which markets receive AQUA rewards (LOBSTR help article). Soroswap now brands itself “The Swap Aggregator for Stellar”, though its own TVL is small at about $1M. Phoenix describes itself as a DeFi hub whose first product is a DEX. At about $50K in TVL it looked near-dormant at our latest check. Sushi also runs a Stellar deployment, at roughly $16M.

Beyond trading, DeFindex aggregates yield strategies and powers the Earn feature in the Beans payments app. Templar Protocol offers lending. FxDAO describes itself as the first decentralised stablecoin protocol on Stellar, backed by XLM reserves, but its own site says it is still in development and DefiLlama lists almost no TVL. One newcomer to watch: Curve announced its first non-EVM integration on Stellar at Meridian 2026, though it was only an announcement at our latest check. For tokenized Treasuries and funds that are starting to appear as DeFi collateral, see our real-world assets guide.

Figures are from DefiLlama at our latest check and change daily. Vault and curator products that DefiLlama also lists largely re-deposit into Blend, so we leave them out to avoid double counting. SDF’s own year-in-review put Stellar DeFi TVL at $211M+ at the end of 2025, up 95% on the year (SDF 2025 review).

Risks: what the YieldBlox exploit taught Stellar DeFi

Just after midnight UTC on 22 February 2026, an attacker targeted a Blend lending pool run by the community YieldBlox DAO. The pool priced USTRY, a tokenized Treasury asset, through the Reflector oracle, which drew on trades in a thin USTRY/USDC market on the Stellar DEX. One transaction pushed USTRY’s reported price from about $1.05 to about $106.73. Using that inflated collateral, the attacker borrowed about 61.2M XLM and 1.0M USDC, roughly $10.2M (Blockaid; BlockSec analysis).

What happened next is unusual. XLM has no issuer that could freeze it, so after Blockaid identified the attacker’s wallets, Stellar’s Tier-1 validators coordinated to reject transactions from those addresses. That “quarantined” about 48.07M XLM, worth about $7.3M at the time. The funds stayed visible on chain but could not move. This was not a protocol-level seizure, and the funds had not been returned when Blockaid published its account, which comes from a party involved in the response. Script3 said affected depositors would be compensated. In May 2026, Protocol 26 introduced a formal mechanism (CAP-77) that lets validators freeze compromised ledger entries by consensus.

Two lessons are worth spelling out. First, the bug was in a pool’s configuration and oracle choice, not in Blend’s core contracts, and other pools were unaffected. Permissionless DeFi moves that risk onto users, who have to judge each pool. Second, validator intervention limited the damage but also showed that a small group of organisations can, in practice, block an address. Some users will see that as a safety net and others as a centralisation concern. Our regulation and safety page covers the wider risk picture.

Using Stellar DeFi from Asia

Most XLM owned in Asia sits on centralised exchanges, not in DeFi. Japanese exchanges held about 564M XLM for customers at the end of September 2026, according to JVCEA statistics, and in a CoinGecko snapshot at our latest check the Korean won was the largest fiat currency for XLM spot trading. To use a Stellar dApp, you first withdraw XLM from the exchange to a self-custody wallet. That is an ordinary Stellar payment costing a fraction of a cent. If you later send funds back to an exchange, always copy the memo it gives you, because a missing or wrong memo can delay or lose the deposit.

Stablecoins are the other way in. USDC is the dominant dollar token on Stellar, with about 300M in circulation at our latest check, and many DeFi markets are quoted against it. Our stablecoins guide explains the issuers and how to verify them.

Local rules matter as much as code. In Vietnam, a State Securities Commission official said in September 2026 that crypto transactions must go through a licensed domestic provider under the new pilot regime, which leaves on-chain DeFi in a legal grey area; see our Vietnam guide. South Korea’s scheduled tax on virtual-asset gains, due from 1 January 2027, covers both transfers and lending, so DeFi income is in scope; our South Korea guide tracks the details. In Japan, crypto gains are still taxed as miscellaneous income at progressive rates of up to 55%.

How to start with Stellar DeFi safely

1. Get a wallet that shows what you sign
   Use a non-custodial wallet with Soroban support and transaction scanning, such as Varial or LOBSTR. Our wallet guide compares the options. Write down your recovery phrase offline, and keep a little XLM for reserves and fees.
2. Start small, then stay small for a while
   Move an amount you could lose without stress. Try one swap on the native DEX, then one small deposit into an established protocol. Watch how withdrawals work before adding more.
3. Verify tokens and contracts
   Check every asset by issuer account and home domain, not by ticker, because copycat tokens exist. Confirm contract addresses from the project’s official site or docs, and cross-check them in an explorer.
4. Read the pool, not just the protocol
   In Blend and similar systems, each pool has its own oracle, collateral and backstop. Prefer pools with liquid collateral, a well-funded backstop and published audits. Treat double-digit yields as a risk signal.

Ryu says

If a yield looks too good, ask who is paying it. On Stellar, as everywhere, the answer is sometimes “the next depositor” or “you, later”.

Stellar DeFi is still young, compact and closely tied to the network’s payments and stablecoin strengths. Thanks to the protocol-level DEX and path payments, a lot of its value reaches users who never think of themselves as DeFi users at all. If you would rather explore the consumer side first, our list of Stellar apps is a gentler starting point.
