ActivemStable CDP Review 2026: Stacked Stablecoin Yield Explained
mStable CDP is the data-listing name for mStable's yield products, which stack stablecoin yield from Aave, Pendle, Ethena and similar sources. Its main draw is hands-off yield. The main caveat is exposure to several third-party protocols, shown by the 2026 apxUSD depeg.

Our verdict on mStable CDP
6.7/10mStable suits DeFi users who want automated stablecoin yield without managing positions across Aave, Pendle and similar markets. Its strengths are diversified yield sources, multiple named audits and open communication about changes, including the apxUSD exit. The main caveat is layered risk: the strategy depends on third-party protocols and on assets that can depeg. Fees are not published on the homepage, so check the docs and app before depositing.

What is mStable CDP?
mStable describes itself as a way to earn yield on stablecoins. The DeFi data listing for this entry is named mStable CDP and puts total value locked at about 2.8 million dollars across Ethereum and Polygon, with two audits listed. The listing's own description says mStable unites stablecoins, lending and swapping into one standard.
The current homepage focuses on yield tokens and a Stacked Yield vault. It says deposits are put to work across supported yield markets, and that positions are managed automatically. It names Ethereum Mainnet, Pendle and Aave as sources of liquidity.
The site's news section shows the product changing in 2026. It added Apyx in May, exited the apxUSD principal-token position on June 2 after the asset depegged, and added mAPOLLO from Midas in July. The project also notes that it is built on Chamber, and says 'mStable remains mStable'.
How mStable CDP works
mStable takes stablecoin deposits and allocates them across supported yield markets. The homepage names Ethereum Mainnet, Pendle and Aave, and recent news adds Ethena and Midas assets. In return, the user receives a token or position that reflects their share of the strategy.
The homepage shows an example where sending 12 returns 15, illustrating the idea of stacking yield on top of yield. Those figures are an illustration, not a promised rate. The position is described as automatically managed, so the protocol adjusts allocations and the user does not.
The yield mix is changed over time. In 2026, the Stacked Yield vault added Apyx, later exited its apxUSD position after a depeg, and then added mAPOLLO. This shows the strategy relies on active curation and on the health of the assets it holds.
6 features
Key features
01
Stacked yield strategy
Deposits are spread across supported yield markets rather than a single source. The site names Aave, Pendle and Ethena-linked assets.
02
Automated position management
The homepage says positions are managed automatically over time, so users do not rebalance themselves.
03
Yield tokens
The site presents yield tokens, such as mPT-sUSDe, that represent a position in the strategy. Each token's mechanics are explained in the docs.
04
Evolving yield mix
The vault adds new yield sources over time, such as mAPOLLO from Midas in July 2026. It also removes sources when risk changes, as it did with the apxUSD position.
05
Audits and bug bounty
The site lists audits by Sherlock, iosiro and Trust Security and links to a bug bounty programme.
06
Docs and community
The site links to docs, stats, a blog archive, Discord and X for community and support.
Pros and cons
What we like
- Automated management means users do not need to rebalance positions themselves.
- Diversifies across several yield sources, including Aave, Pendle and Ethena-linked assets.
- Contracts have been audited by Sherlock, iosiro and Trust Security, and a bug bounty is listed.
- The project publishes news updates, including a candid note about exiting a depegged asset.
- Documentation, stats, Discord and a legacy blog are linked from the homepage.
Watch out for
- Yield comes from several third-party protocols, so a failure in any of them can hurt the position.
- The apxUSD depeg in 2026 forced an exit from a position, showing the strategy can hold assets that lose their peg.
- Fees, including any performance or management fee, are not stated on the homepage.
- TVL is modest at about 2.8 million dollars, which is small next to the large lending markets it builds on.
- Marketing phrases such as 'billionaire liquidity' and 'snipe competitive liquidity' describe advantages that cannot be checked from the site.
- The data listing files the product under CDP, while the homepage describes a yield product, which can confuse newcomers.
mStable CDP fees
The homepage does not publish a fee schedule. Any performance, management, deposit or withdrawal fees are not stated there. Users would see them in the docs or in the app before confirming a deposit.
On-chain use also means network gas fees on Ethereum or Polygon when depositing and withdrawing. Gas on Ethereum Mainnet can be significant for small deposits.
Is mStable CDP safe?
The homepage says mStable uses contracts with multiple audits and four years of battle testing, and names Sherlock, iosiro and Trust Security. It also links to a bug bounty. The data listing shows two audits. The project does not publish team or licensing details on the homepage, and it is a non-custodial DeFi protocol rather than a regulated service.
The main risks are indirect. Yield depends on external protocols and on assets that can lose their peg, as the apxUSD depeg in 2026 showed. The project responded by exiting the position, but depositors can still be exposed to losses before such an exit. Treat any yield figure as variable and unguaranteed.

Who mStable CDP is for
mStable is aimed at crypto holders who already understand stablecoins, wallets and gas fees and want passive yield without actively rebalancing. It is less suited to beginners who need guaranteed returns, or to anyone unwilling to accept smart-contract and depeg risk.
mStable CDP FAQs
What is mStable?
mStable is a DeFi project that lets users deposit stablecoins and earn yield. The homepage describes products that spread deposits across supported yield markets and manage the position automatically. It was originally known for stablecoin-related products, and it now centres on yield tokens and a Stacked Yield vault.
How does mStable generate yield?
The site says deposits are put to work across supported yield markets, with Ethereum Mainnet, Pendle and Aave named. Recent news mentions Ethena and Midas assets as additional sources in the Stacked Yield vault. Actual returns are variable and are not guaranteed.
Do I need to manage my position manually?
The homepage says positions are managed automatically over time and that the position 'never expires'. Users deposit and withdraw, and the product handles the allocation. Users still need to monitor risks and news.
Is mStable secure?
The homepage says the contracts have multiple audits and four years of battle testing, naming Sherlock, iosiro and Trust Security, and it links to a bug bounty. Audits reduce risk but do not remove it. Smart-contract, depeg and counterparty risks remain.
Which networks does mStable run on?
The data listing shows Ethereum and Polygon. The homepage emphasises Ethereum Mainnet liquidity. The FAQ has a section on supported networks, so check the app and docs for the current list.
What are the risks of using mStable?
Risks include smart-contract bugs, depegs of stablecoins or yield-bearing assets, and failures in underlying protocols. A news item on the site notes that the Stacked Yield vault exited its apxUSD position on June 2, 2026 after that asset depegged. Only deposit funds you can afford to lose.
