Cian Protocol Questions Answered

Everything you wanted to know about how Cian Protocol works — from depositing your first asset to understanding how yield is generated across multiple chains. You can also visit the company page for background on the team and mission.

What exactly is Cian Protocol and what problem does it solve?

Cian Protocol is a yield aggregation protocol that routes deposited assets across multiple DeFi strategies simultaneously. Think of it as an automated portfolio manager — one that never sleeps and never misses a rebalancing window.

The core problem it addresses is fragmentation. In practice, a user wanting to earn yield on, say, BTCB or stETH would need to manually track rates across Aave, Compound, Maple Finance, and a dozen other protocols. That takes time most people simply don't have.

Cian Protocol wraps this complexity inside a single vault interface. You deposit once, and the protocol's on-chain strategies handle allocation, rebalancing, and compounding on your behalf.

Which blockchain networks does Cian Protocol support?

Cian Protocol currently operates on Ethereum mainnet, BNB Smart Chain (BSC), Arbitrum, Mantle, Plasma, and Sei. That's six networks as of mid-2026, with more under evaluation.

Each chain has its own vault deployment, meaning a vault on BSC uses BSC-native lending markets while an Ethereum vault taps Ethereum-based protocols like Aave V3.

Multi-chain support isn't just a marketing point here — it genuinely widens the yield surface. Some of the highest-APY opportunities appear on newer chains where liquidity is still building.

How is the displayed APY calculated?

APY figures shown in the Cian Protocol interface reflect a weighted average of the underlying position yields, adjusted for the leverage multiplier applied to each strategy. A 7X leveraged recursive staking position, for instance, amplifies the base supply APY but also amplifies liquidation risk — the UI shows both a gross APY and a net APY after protocol fees.

The "Current APY" is recalculated on a rolling basis using on-chain data from the past 7 days by default (you can switch to 30-day or 90-day views). Averages smooth out short-term spikes.

One thing worth noting: APY is not guaranteed. Rates on Aave, Maple, and similar markets change with utilization. Cian Protocol updates its internal allocation periodically to chase higher-yielding positions, but there is always some lag.

What tokens can I deposit into Cian Protocol vaults?

Supported deposit tokens span stablecoins and volatile assets. On Ethereum you'll find vaults for stETH, wBETH, rsETH, ezETH, uniBTC, and BTCLST. Stablecoin options include USDT0 and USDC across multiple chains. BSC vaults cover BTCB, slisBNB, and USD1.

The Mantle deployment focuses on Bybit-issued assets like USDT0 and USDC, which tend to carry competitive APYs due to Bybit's incentive programs.

New tokens are added through governance proposals. If you hold an asset that isn't listed yet, the Cian Protocol main app has a community forum where requests can be submitted.

Has Cian Protocol been audited? Is the code open source?

Yes. Cian Protocol vaults carry an "Audited" badge visible in the interface, and the protocol has gone through multiple independent security reviews. Audit reports are linked directly from each vault's details tab.

The codebase is not fully open source at the strategy level — some strategy logic is kept proprietary to reduce front-running risk. However, vault contracts that hold user funds are verifiable on-chain via Etherscan, BSCScan, and equivalent explorers for other chains.

The team also maintains an "Institution Trusted" certification displayed on select vaults, indicating additional due diligence beyond the base audit. That said, no audit eliminates smart contract risk entirely. You should always read the risk disclosures before depositing.

What is a "Yield Layer" in the context of Cian Protocol?

The "Yield Layer" is Cian Protocol's core product category. Rather than offering a single fixed strategy, a Yield Layer vault dynamically routes assets across multiple underlying positions — lending markets, recursive staking loops, liquidity pools — depending on which offers the best risk-adjusted return at any given time.

Each Yield Layer has a FlowMap — a visual diagram showing how funds move from your deposit token through the strategy layers to the yield sources. You can inspect this in the vault UI.

The name "Yield Layer" also reflects a broader ambition: Cian Protocol positions itself as infrastructure that other protocols can build on top of, similar to how Ethereum serves as a base layer for applications.

How does leveraged recursive staking work inside a Cian Protocol vault?

Recursive staking — sometimes called looping — works like this: you deposit 1,000 syrupUSDT. The strategy supplies that to Aave V3 as collateral and borrows USDT against it. That borrowed USDT is swapped for more syrupUSDT and re-supplied. This cycle repeats until the position reaches the target leverage ratio, in some vaults up to 7X.

The net yield is the supply APY on the amplified position minus the borrow APY on the debt. When supply rates exceed borrow rates — which is common for liquid staking tokens — the spread compounds quickly.

The risk is liquidation if the value of the collateral drops relative to the debt. Cian Protocol monitors health factors continuously and can de-lever automatically if thresholds are breached. The Risks tab in each vault explains the specific liquidation parameters.

What happens when I deposit — what do I receive in return?

When you deposit into a Cian Protocol vault, the protocol mints receipt tokens to your wallet. These are ERC-20 tokens representing your share of the vault's total assets. Their value increases over time as yield accrues.

The deposit and receipt token pair is shown prominently in each vault's detail view — for example, you might deposit syrupUSDT and receive a vault-specific share token in return. Withdrawing burns those receipt tokens and returns the underlying assets plus earned yield.

Receipt tokens are transferable and composable. In principle you can use them as collateral in other protocols, though Cian Protocol doesn't formally support this workflow — it's something advanced users explore independently.

Are there deposit limits or caps on Cian Protocol vaults?

Yes, most vaults have a TVL cap. The syrupUSDT Yield Layer on Plasma, for instance, shows a cap of 10M syrupUSDT. Once a vault approaches its cap, new deposits may be paused temporarily.

Caps exist for two reasons. First, very large positions in a single lending market can move rates unfavorably. Second, capping allows the Cian Protocol team to maintain tighter risk controls as they scale.

The current fill percentage is visible in the vault UI as a circular progress indicator. If a vault is near capacity, you might want to check back after a rebalancing event or look for an alternative vault with the same underlying asset.

What fees does Cian Protocol charge?

The protocol takes a performance fee on earned yield. This is reflected in the difference between "APY" (gross) and "Net APY" displayed in the vault cards. There is no deposit or withdrawal fee on most vaults.

Gas fees are separate and depend on the network. On Ethereum mainnet these can be meaningful for smaller positions, which is why Arbitrum and BSC vaults tend to be more accessible for retail-sized deposits.

Fee structures are documented in the Details tab of each vault. The team has indicated that fee parameters can be updated via governance, so it's worth checking the latest vault documentation before large deposits.

Can I use Cian Protocol if I've never interacted with DeFi before?

You can, but you'll need the basics first: a self-custody wallet like MetaMask or a WalletConnect-compatible app, some ETH or BNB for gas, and the asset you want to deposit. The Cian Protocol interface handles everything after that.

That said, DeFi carries risks that traditional finance doesn't. Smart contract bugs, oracle failures, and market volatility are all real possibilities. New users should start with smaller amounts to get comfortable with the mechanics before committing larger sums.

The FlowMap diagrams in each vault are genuinely helpful for understanding where your money goes — more transparent than most DeFi products in this space.

What is the Eco. Earn Vault and how is it different from a Yield Layer?

The Eco. Earn Vault (short for Ecosystem Earn Vault) is a pre-deposit product where users commit assets before the full vault strategy goes live. It typically offers a fixed or estimated return for an early lock-up period, rewarding users willing to accept some uncertainty about the final strategy composition.

A Yield Layer, by contrast, is a fully deployed vault with live strategies and real-time APY data. The Eco. Earn Vault is more like a reservation — you're committing early in exchange for potential upside.

Both product types are accessible from the same sidebar navigation in the Cian Protocol app. The Eco. Earn Vault section shows time-limited entries with their own APY estimates and lock-up schedules.

How does the Cian Protocol referral program work?

Cian Protocol runs a referral program accessible at referral.cian.app. You generate a unique referral link and share it. When someone deposits through your link, you earn a percentage of the yield generated by their deposits — the exact rate is displayed in the referral dashboard.

There's no cap on the number of referrals. The rewards accumulate in your account and can be claimed periodically. Referral earnings are paid in the same token as the referred vault's yield.

It's a relatively clean setup compared to some programs in DeFi that make claiming unnecessarily complex. One thing to verify: confirm the referral program terms haven't changed since this was written, as incentive structures do get updated.

What risks should I be aware of before depositing?

Four main risk categories apply to Cian Protocol vaults. Smart contract risk — a bug in the vault or underlying protocol code could result in lost funds. Liquidation risk — leveraged positions can be liquidated if collateral values drop sharply. Underlying protocol risk — Cian Protocol depends on third-party protocols like Aave; if those are exploited, funds in positions using them are affected too. Finally, market risk — volatile assets can lose value independent of any strategy mechanics.

The Safety score (rated out of 5 in the vault UI) gives a quick aggregate view of these factors for each vault. A score of 4/5 indicates low but non-zero risk. You can drill into the Safety tab for a detailed breakdown.

The team has published a dedicated Risks tab per vault. Reading it before depositing isn't optional — it's the minimum due diligence for any DeFi product. See the company page for more on Cian Protocol's approach to risk management.

Where can I track my Cian Protocol positions and portfolio performance?

The Portfolio section in the main Cian Protocol app shows all active positions once you connect your wallet. It displays current TVL, accrued yield, time since deposit, and individual vault performance.

On-chain activity is always verifiable independently. Each vault contract address is linked from the vault detail page — you can paste it into any block explorer and see your position directly on-chain without relying on the Cian Protocol front end.

For historical APY data, the APY chart in each vault shows rolling averages over different time windows. This helps you judge whether current rates are representative or an anomaly.
