The Stablecoin Standard Framework for DeFi Stablecoins

Executive Summary

The Stablecoin Standard (SCS) introduces a structured framework to support decentralized (DeFi) stablecoins in meeting evolving market standards, risks and regulatory and policy discussions. Version 2.0 of the SCS framework focuses on three pillars:

Operational Resilience

Requiring strong ollateralization, liquidation protocols, and stress-tested risk systems.

Transparency and User Protection

Emphasizing open governance, real-time disclosures, and informed user engagement.

Product Commitments

Encouraging responsible financial crime mitigation, cybersecurity practices, and policy-aligned conduct.

The framework is voluntary but offers a pathway to qualification as a "qualified DeFi stablecoin." Projects adopting these standards demonstrate risk mitigation, preparedness for legal or regulatory review and contribute to sector-wide credibility. We acknowledge the effort to align with the new framework and encourage iterative progress.1

Invitation to Collaborate: SCS invites DeFi communities, public policy experts, regulators and technologists, to provide input, validate use cases, and contribute to the evolution of this decentralized framework. Stakeholders interested in contributing or endorsing the framework are encouraged to engage via future SCS Policy working group sessions by reaching out to Global Policy lead at the Stablecoin Standard. policy@stablecoinstandard.com 

Introduction

Version 2.0 of the SCS standards introduces a dedicated framework for decentralized stablecoins operating within a DeFi ecosystem. Building on the principles first introduced for centralized stablecoins, this version addresses the unique technology and operational, risk, and governance features of DeFi stablecoins. The objective is to promote transparency, resilience, and responsible innovation by encouraging adoption of minimum standards that align with emerging risks, community-driven practices and regulatory and policy discussions.

This framework is intended for two primary audiences:

  • DeFi projects, including protocols, DAOs, service providers and governance participants, to evaluate and enhance the design and operation of stablecoin products.

  • Regulators and policymakers, to better understand the mechanics and evolving practices within decentralized stablecoin ecosystems.

By identifying and promoting sound practices, the SCS framework aims to bridge current policy and regulatory gaps and contribute to global efforts toward appropriate oversight and market integrity. It also supports risk mitigation and regulatory readiness by providing a structured, principles-based approach to stablecoin evaluation that complements—but does not conflict with—existing or pending legal regimes.

Definition

For the purposes of Version 2.0 of the SCS stablecoin framework ("Standards" or "framework") for decentralized finance ("DeFi"), a DeFi stablecoin is defined as:

A soft-pegged token issued on a blockchain, managed via smart contracts or other decentralized mechanisms. DeFi stablecoins must maintain at least a 1:1 reserve ratio using on-chain collateral or algorithmic structures, without reliance on any single party with unilateral control.

DeFi stablecoins that meet key quality principles—particularly regarding redeemability and conversion risks—are referred to as "qualified DeFi stablecoins." These are expected to meet all other requirements in this framework, including governance and protocol-level safeguards where applicable. See the SCS framework for centralized stablecoins for comparison. 

Scope and Typology

DeFi stablecoins aim to track a currency or crypto asset via on-chain mechanisms such as crypto collateral, smart contract controls, or algorithmic supply adjustments. These systems avoid reliance on unilateral control over issuance, conversion, or redemption. Some tokens also incorporate yield mechanisms (e.g., staking rewards, incentives, or emissions).

The term encompasses both:

  • Endogenously backed stablecoins, which use collateral generated within the protocol (e.g., governance or liquidity tokens, or native volatile assets).

  • Exogenously backed stablecoins, which use external collateral, are typically viewed as more resilient due to reduced protocol-specific risk (e.g., DAI backed by USDC).

The SCS DeFi framework recognizes this evolving landscape and sets out to improve transparency around product features, particularly collateral and risk management practices.

The objective is to help DeFi projects assess how features like collateral volatility, decentralization, and peg mechanics intersect with regulatory and legal obligations. SCS encourages adoption of this framework to support safe, transparent, and sustainable growth of qualified DeFi stablecoins.

Standards

  • DeFi stablecoins are expected to be supported by decentralized operational practices, such as the following, through protocol design, governance resolutions, service providers’ (SPs) obligations or other means:

    1.1 Maintain fully collateralized on-chain reserves and apply over-collateralization where market, credit, or concentration risks cannot be adequately managed.

    1.2 Collateral assets should be on-chain, stress-tested and overcollateralized, where possible and relevant, to ensure they fully cover the total soft-peg value, even under extreme conditions. 

    1.3 Avoid unnecessary risk-taking with the collateral backing the stablecoin. Collateral assets should be valued daily using oracle mechanisms on a mark-to-market basis and should cover at least 100% of the par value of all outstanding stablecoins. 

    1.4 For any collateral assets involving indirect counterparty or custodial risks, appropriate risk-mitigation mechanisms should be applied where available.

    1.5 Collateral should be programmatically separated by the protocol and transparently maintained for the benefit of stablecoin holders, distinct from other protocol-controlled funds. 

    1.6 Promote collateral diversity, and avoid excessive concentration in illiquid or highly correlated assets.

    1.7 Restrict re-hypothecation of collateral and support mechanisms that maintain sufficient liquidity for redemption or automated liquidation. Limit collateral types, prevent recursive rehypothecation, apply conservative haircuts to reused assets, and provide clear collateral transparency for users

    1.8 Design products to support timely redemption without unreasonable redemption costs. 

    1.9 Commit to disclosures of collateral composition and valuation through transparent dashboards, supported by periodic third-party audits, where feasible, formal verification of key smart contract components. 

    1.10 Implement mechanisms designed to preserve core functionality under adverse conditions and mitigate user impact in the event of extreme collateral depletion or systemic failure. 

    1.11 Implement on-chain mechanisms and smart-contract logic that manage investment-related activities and maintain liquidity for redemptions. 

    1.12 Liquidity risk-management practices and periodic stress testing are expected. e.g., ability to process 10% of TVL within a 72-hour period or some other reasonable and disclosed standard.

  • DeFi stablecoins are expected to be supported by practices that promote transparency, user protection, and accountable conduct through the following actions - implemented via protocol design, governance resolutions, service providers (SPs) or other means:

    2.1 Implement decentralized governance that supports transparent and verifiable collective decision-making, and that may allow protocol upgrades or parameter adjustments where appropriate. 

    2.2 Adopt transparent governance and risk-management practices that clearly define protocol roles, administrative permissions, and access rights. Governance structures and adjustable parameters should be publicly documented and verifiable on-chain. Where governance actions could result in protocol upgrades or material changes, protocols are expected to  disclose such proposals in advance and enable appropriate community input.

    2.3 Provide on-chain data showing total circulation, collateral composition, and collateralization ratios. Projects should support periodic third-party audits, smart contract reviews, and performance reporting. DeFi stablecoins are expected to conduct ongoing security assessments, publicly disclose past vulnerabilities, patches, and audit results, and implement bug bounties to enhance user trust and reduce systemic risk.

    2.4 Provide clear and accessible documentation for general reference and compliance purposes that explains key risks and economic mechanisms. These may include the appropriate fees, redemption processes, stabilization mechanism, collateral valuation and management and any available dispute resolution process. DeFi stablecoins  should clearly disclose that redemption is not in fiat currency and that value recovery depends on the protocol’s condition and on-chain liquidation processes rather than enforceable legal redemption rights. For yield-bearing stablecoins, where such features are permitted, protocols should disclose the reward structure, projected return profiles, and associated risks.

    2.5 Maintain a user communication process for addressing vulnerabilities, bugs and other incidents. This may include publicly accessible terms of use, incident-reporting channels, status pages, and information on issue resolution.

    2.6 Commit to standards of ethical conduct and protect user privacy, through governance proposals or otherwise, for managing conflicts of interests, minimizing unnecessary data collection, enabling pseudonymous use where feasible, and clearly disclosing any analytics or monitoring tools used by the protocol.

    2.7 Promote protocol development and maintenance by contributors with relevant expertise and track record. Where compatible with a decentralized model, DeFi stablecoins should disclose core SPs/contributors and grant recipients to support transparency and accountability.

    2.8 Provide user-facing information through in real-time user interfaces, such as terms of use, explanatory materials, notifications, and risk disclosures. These resources should be easily accessible and enable users to understand protocol and other functions, especially redemption triggers, risk scenarios, including vulnerability events, and collateral-based recovery mechanisms.

  • DeFi stablecoins should take good faith steps to prevent cyber threats and financial crimes, maintain operational security, and promote responsible conduct. These explanations may  be met through protocol design, governance actions, service-provider obligations or other means, in line with fair practices and evolving regulatory standards.

    3.1 Commit to take reasonable measures to mitigate risks related to fraud, theft and market manipulation. These  may include thoughtfully designed pause or emergency controls, and where appropriate, the use of transaction screening and reporting logic into smart contracts and protocol-level tools.2

    3.2 Maintain appropriate cybersecurity, information security, and data privacy controls and adopt fair marketing practices where applicable.

    3.3 Adopt a tailored sanctions compliance framework for front-end interfaces that may incorporate decentralized or privacy-preserving approaches for UI user verification where applicable, together with appropriate mechanisms for transaction-monitoring and reporting that align with relevant regulatory requirements. These expectations do not apply where custody and control are fully decentralized. 

    3.4 Implement a risk management program that includes periodic risk assessments, reviews of the performance of relevant compliance and cybersecurity tools and governance-related measures that support responsible oversight of high-risk activities such as protocol upgrades, UI functionality and treasury movements.

    3.5 Conduct and document ongoing due diligence on technical and protocol-level components. This includes regular smart contract audits, security testing, and updates reflecting emerging security and applicable compliance, and regulatory considerations.

    3.6 Implement mechanisms that enable  compliance oversight, transparent decision-making, and effective control over activities that present elevated risk.

    3.7 Engage with appropriate resources to remain informed on applicable legal and regulatory developments and to contribute, where feasible, to the evolution of decentralized compliance practices and safer DeFi stablecoin ecosystems.

Conclusion

As decentralized finance continues to evolve, the standards that inform the design and operation of DeFi stablecoins should advance accordingly. This framework aims to support DeFi ecosystems in strengthening user protections, improving risk-management practices, and promoting sustainable and transparent system design. DeFi stablecoins that align with these standards may be recognized as "qualified DeFi stablecoins" under the SCS framework, reflecting preparedness for responsible operation and emerging regulatory expectations.
