Cian Protocol
The yield layer built to redistribute returns across DeFi — so your assets work harder, on every chain, at every moment.
Our Mission
DeFi has a fragmentation problem. Yield opportunities scatter across dozens of protocols, chains, and token standards — and most holders never capture more than a fraction of what's available. The team behind Cian Protocol built this protocol to change that.
The mission is straightforward: aggregate, optimize, and distribute yield automatically. No manual rebalancing. No jumping between dashboards at 2 a.m. You deposit assets, the protocol handles the rest.
Cian Protocol operates across Ethereum, BNB Chain, Arbitrum, Mantle, Sei, and Plasma — with more networks in active development. The protocol has been running since 2022 and has processed hundreds of millions in vault volume.
Technology
The Cian Protocol platform is built on smart contract vaults that route deposited assets through a set of pre-audited strategy positions. Each vault holds one or more strategies — recursive staking, lending loops, liquidity provision — chosen for their risk-adjusted return profile at any given time.
On the Ethereum side, the Cian Protocol protocol integrates with Aave V3, Lido, KelpDAO, Renzo, and several other battle-tested lending markets. Smart contracts are written in Solidity and tested with Hardhat before every deployment. Strategy logic is deterministic — it doesn't rely on off-chain oracles for basic operations.
Our Approach to Risk
Yield without transparency is just hope. The Cian Protocol's protocol makes every strategy visible — you can see exactly where your assets go, what leverage is applied, which third-party protocols handle the capital, and what each position's historical liquidation count is.
Each vault carries a Safety Score. That score reflects audit status, protocol age, liquidation history, and position diversity. The stETH Yield Layer on Ethereum, for instance, carries a score of 4 — computed from independent audits, two years of uninterrupted operation, and zero liquidation events.
All vaults are audited before launch. No strategy goes live without passing both internal review and external audit. Some vault types — particularly those involving recursive staking — go through additional formal verification before the team deploys them to mainnet.
What We Build
The Cian Protocol platform ships two main product lines. The Yield Layer is the core: structured vaults that accept tokens like stETH, BTCB, rsETH, syrupUSDT, and slisBNB, then route them through multi-step strategies to generate above-market returns.
The second line is the Eco. Earn Vault — a pre-deposit product aimed at institutional participants and early adopters who want exposure to upcoming strategies before they go fully live. It launched as a staged product and has accumulated significant TVL ahead of formal strategy deployment.
Both product lines share the same underlying smart contract infrastructure and the same auditor-reviewed codebase. You can explore individual vault details — strategy allocations, APY history, utilized protocols — directly in the main app. For deeper technical questions, visit the knowledge base.
Team & Culture
The team behind Cian Protocol spans smart contract engineering, protocol design, on-chain analytics, and product. Most of the engineering team came from DeFi-native backgrounds — people who ran their own validators, lost money to bad strategies in 2021, and decided to build something better.
Honestly? The team is small by traditional standards. That's intentional. Fewer people means faster iteration, cleaner code ownership, and sharper focus on what actually matters to depositors.
Decisions at Cian Protocol are made on-chain where possible and documented publicly. Governance proposals, treasury movements, and strategy updates are visible to anyone. The protocol has a referral program for community contributors, and active community members can participate in testing new vaults before public launch.
Where We're Headed
The next phase of Cian Protocol's protocol development focuses on three things: expanding the vault catalogue to cover more liquid staking tokens, deepening integrations with emerging lending markets on newer L2 networks, and improving the tooling around yield transparency.
On the institutional side, Cian Protocol is building dedicated vault configurations that meet the compliance requirements of larger capital allocators — segregated accounting, configurable withdrawal windows, and additional off-chain reporting layers.
The protocol is not standing still. New vaults ship every few weeks. Check the live app for the most current APY data, or read through the knowledge section for detailed explanations of how individual strategies work.
