[PRESS RELEASE – New York, USA, February 16th, 2026]

Fresh off its $250M Series C, Rain implements a unified detection-to-response framework to further protect stablecoin payments

Guardraila real-time blockchain security platform backed by Coinbase Ventures and Haun Ventures, has launched an integrated security model that links continuous runtime detection directly to managed incident response. The model focuses the attack cycle on the crucial step between vulnerability exposure and live attacks.

Rainthe global stablecoin payments platform for enterprises, neobanks and platforms, recently implemented this unified security framework across its smart contracts and wallets used for settlement with Visa, further improving security for millions of purchases in more than 150 countries.

Stablecoin transaction volumes reached $27.6 trillion in 2024, surpassing Visa and Mastercard combined. As the traditional financial sector accelerates its movement up the chain, the security challenges and unique risks it poses are widening the gap.

The blockchain industry lost more than $3.4 billion due to theft in 2025. More than 90% of exploits targeted code where security audits and a comprehensive review were completed. The pattern is consistent: audits examine code during development, but attacks occur in production environments through compromised keys, operational errors, and runtime exploits that static code review cannot anticipate and prevent.

Why post-deployment security is important for Stablecoins

The Stablecoin infrastructure works differently than typical DeFi protocols. When software events translate directly into payment results in more than 150 countries, a configuration error or malicious transaction pattern can cause immediate harm to the user, with limited ability to reverse it.

Each application of stablecoin technology by geography, financial application, underlying asset, and wallet infrastructure brings incredible potential, while simultaneously increasing the likelihood of security risks for unique attack vectors. Industry data shows that off-chain incidents, compromised keys, phishing and operational errors now represent the majority of lost funds, underscoring the need for security that expands the attack surface to: onchain activity, off-chain integrations, API dependencies and user-facing access points.

“As Web3 matures, risk management and proactive security measures that leading institutions have built into traditional products should be offered when transacting with stablecoins, just like their fiat counterparts. Uniting risk detection, real-time detection and managed automated response is the gold standard we are excited to shape for our industry,” said Samridh SalujaCEO of Guardrail.

How the framework works

Guardrail’s platform evaluates transactions and status changes in real time using configurable detection modules. These identify conditions beyond standard vulnerability signatures, economic anomalies, consent violations, oracle anomalies, and abnormal approval patterns with sub-second detection across more than 30 chains.

When an incident is flagged, alerts are passed on immediately managed response workflows developed in collaboration with Cantina, a Web3 security company. The response works through 24/7 triage, pre-built playbooks for technical and administrative processes, and escalation paths with defined ownership. Evidence is collected proactively, resulting in an informed security posture.

Institutional security for Onchain Finance

As stablecoins move toward enterprise payments and institutional custody, security expectations are changing. Partners evaluating onchain infrastructure ask direct questions: who owns the containment? How is authority structured? What trail of evidence is there? How does the system perform at 3am on a Saturday?

Rain’s security model with Guardrail and Cantina answers these questions universally. Runtime signals feed-driven incident workflows. Escalations lead to said owners. The containment follows documented scripts. Evidence pathways support both internal assessment and partner commitment.

“Our business partners rely on Rain to protect real-world payment flows amounting to billions of dollars annually. The integration of Guardrail’s real-time monitoring and Cantina’s managed response capabilities increases our ability to detect anomalies early and act decisively,” said Charles Yoo-NautCTO and co-founder of Rain. “This is an important addition to the broader set of onchain security partners we rely on to protect our ecosystem.”

The integrated detection and response model is a template for protocols that manage stablecoin infrastructure, custody flows, enterprise payments, and on-chain financial products.

About Guardrail

Guardrail is a real-time blockchain security platform with sub-second detection across more than 24 chains. Backed by Coinbase Ventures and Haun Ventures, the platform uses AI-powered anomaly detection and configurable security modules to identify exploits before the money runs out, with automated response capabilities including contract pauses and circuit breakers. Guardrail currently protects more than $20 billion in TVL through thousands of contracts for protocols including Euler, EigenLayer, BadgerDAO and Bluefin.
