Catenaa, Sunday, February 22, 2026- Guardrail, a blockchain security platform backed by Coinbase Ventures and Haun Ventures, has launched a proactive security model linking continuous runtime detection with managed incident response for stablecoins.
The platform addresses the critical period between vulnerability exposure and live attacks, protecting enterprise and consumer payments on blockchain networks.
Rain, a global stablecoin payments provider, recently deployed Guardrail’s framework across its smart contracts and wallets used for Visa settlements, securing millions of transactions in over 150 countries.
Stablecoin transaction volumes surpassed $27.6 trillion in 2024, surpassing traditional card networks. Industry data shows that most attacks target code already audited before deployment, highlighting the need for post-deployment monitoring.
Guardrail’s model evaluates transactions and state changes in real time across 30+ chains, detecting anomalies, economic irregularities, oracle deviations, and unusual approval patterns within sub-second intervals.
When an incident is flagged, alerts feed into managed response workflows developed with Web3 security firm Cantina.
The system ensures 24/7 triage, automated playbooks for containment, escalation to named owners, and evidence capture for compliance and audit purposes.
Rain’s CTO, Charles Yoo-Naut, noted the importance of runtime monitoring and automated response in safeguarding billions of dollars in enterprise payments.
The framework offers institutional-grade security for stablecoins, custody flows, and onchain financial applications, establishing a template for proactive defense across the industry.
Guardrail protects over $20 billion in total value locked, supporting protocols such as Euler, EigenLayer, BadgerDAO, and Bluefin.
The platform combines AI-driven detection with configurable modules, automated contract pausing, and circuit breakers to prevent fund loss and enhance operational resilience.
