What It Is

Sepehr is an upcoming non-custodial DeFi liquidation protection protocol. It is not positioned as an exchange or wallet, but rather as an automated “guardian” for positions in lending protocols. According to the official website, it is currently in the coming soon stage, with its testnet running on Arbitrum Sepolia. The mainnet launch is planned to start with Arbitrum One, initially covering Aave v3, Compound v3, and Morpho Blue.

Core Capabilities and Security Mechanisms

At the core of Sepehr is a keeper network that continuously monitors users’ health factor in supported protocols. When a position approaches the liquidation threshold, the system attempts on-chain rescue through flash loans, repayment, swaps, and rebalancing, all within a single atomic transaction. It emphasizes “intervention, not notifications,” making it suitable for scenarios where users may be asleep or unable to react quickly enough during second-level flash crashes. On the security side, Sepehr uses a non-custodial design and does not hold users’ collateral. Users grant protocol-specific, revocable permissions. However, the website also clearly states that the protocol is experimental software, smart contracts may contain vulnerabilities, and external audits will be completed before real funds go live. At this stage, it should not be considered a mature product.

Pricing, Compliance, and Limitations

In terms of fees, the official website has not disclosed any subscription fees, success fees, or other pricing models. Its terms also note that fees, supported chains, and features may change before the official launch. On compliance, the terms of service state that French law applies and that disputes fall under the jurisdiction of French courts, but there is no disclosure of any financial license or regulatory registration. The product does not offer fiat on/off-ramps, nor does it specify any KYC requirements.

Pros, Cons, and Who It Is For

The main advantage is its clear focus: solving the real problem of delayed liquidation response in DeFi lending, while prioritizing integrations with major lending protocols. Its non-custodial model and revocable permissions also align with the basic security preferences of DeFi users. The drawbacks are equally clear: it has not launched on mainnet, external audits are not yet complete, pricing is unknown, and under extreme market conditions, flash-loan liquidity, on-chain congestion, or price slippage could still cause rescue attempts to fail. It is better suited to intermediate and advanced DeFi users familiar with Aave, Compound, and Morpho, rather than beginners looking for zero-risk custody or fiat services.

Access from China and Alternatives

The official website does not provide information on access from mainland China, payments, or localization. Actual accessibility will depend on the user’s network environment. Users looking for similar position management tools may consider DeFi Saver, Instadapp, or Summer.fi, or set more conservative collateral ratios and monitoring strategies directly within Aave, Compound, or Morpho.
