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

Rain, fresh out of a $250M Series C, uses a collaborative feedback discovery framework to improve stablecoin payments

Guardrail, a real-time blockchain security platform backed by Coinbase Ventures and Haun Ventures, has launched an integrated security model that connects continuous runtime detection directly to managed incident response. The model addresses the attack cycle at the critical step between vulnerability exposure and live attack.

Rain, a global stablecoin payment platform for businesses, neobanks, and platforms, recently deployed this integrated security framework within its smart contracts and wallets used for Visa transactions, further improving the security of millions of purchases in more than 150 countries.

Stablecoin transaction figures will exceed $27.6 trillion by 2024, surpassing Visa and Mastercard combined. As traditional currencies accelerate their movement on the chain, the security challenges and unique risks they pose widen the gap.

The blockchain industry has lost more than $3.4 billion due to theft by 2025. Code for more than 90% of the intended actions when the security test and full review was completed. The pattern does not change: audits inspect code during development, but attacks occur in production environments with vulnerable keys, performance failures, and runtime exploits that static code reviews cannot anticipate and prevent.

Why Post-Deployment Security Matters for Stablecoins

Stablecoin infrastructure works differently from standard DeFi protocols. When software events translate directly into payment results in 150+ countries, a configuration error or malicious transaction pattern can cause immediate harm to users, with limited recovery options.

Each application of stablecoin technology in terms of geospatial, financial use, underlying assets, and wallet infrastructure brings incredible power while simultaneously increasing the potential for security vulnerabilities from different attack vectors. Industry data shows that off-chain incidents involving key compromise, phishing, and operational failures now represent the majority of lost funds, which underscores the need for security that expands the attack surface into: onchain activity, offchain integration, API dependencies, and user-facing entry points.

“As Web3 grows, the risk management and rapid security measures leading institutions built on standard products need to provide when trading stablecoins, like their fiat counterparts. Combining risk detection, real-time detection and automated response is the gold standard we are happy to lend to our industry,” said Samridh Salujathe CEO of Guardrail.

How the Framework Works

The Guardrail platform monitors transactions and status changes in real time using configurable detection modules. This identifies cases beyond the usual vulnerability signatures, economic anomalies, consent violations, voice deviations, and unusual authorization patterns with sub-second detection across 30+ chains.

When an incident is flagged, the notification route goes directly to a managed workflow developed in partnership with Cantina, a Web3 security company. The answer works with 24/7 triage, pre-built playbooks for all technical and management tracks, and escalation paths with defined identities. Evidence is continuously captured, resulting in an informed security posture.

Institutional-Grade Security for Onchain Finance

As stablecoins move into business payments and institutional storage, security expectations are changing. Partners exploring onchain infrastructure are asking specific questions: Who owns the container? How is authority created? What trail of evidence is there? How does the show work at 3am on a Saturday?

Rain’s security model with Guardrail and Cantina answers these questions globally. Runtime signals control the workflow of an event. Route of promotions to named owners. The content follows the written playbooks. Evidence trails support both internal review and partner due diligence.

“Our business partners rely on Rain to protect real-world transactions totaling billions of dollars annually. Combining Guardrail’s real-time monitoring with Cantina’s managed response capabilities enhances our ability to detect anomalies early and take decisive action,” it said. Charles Yoo-NautCTO and co-founder of Rain. “This is an important addition to the extensive set of onchain security partners we rely on to secure our ecosystem.”

The integrated discovery and response model is a template for protocols that operate stablecoin infrastructure, storage flows, business payments, and onchain financial products.

About the Guardrail

Guardrail is a real-time blockchain security platform with sub-second access across 24+ blockchains. Backed by Coinbase Ventures and Haun Ventures, the platform uses AI-powered anomaly detection and configurable security modules to identify exploits before funds are released, with automated response capabilities including contract freezes and circuit breakers. Guardrail currently secures over $20+ billion in TVL across thousands of blockchain contracts including Euler, EigenLayer, BadgerDAO, and Bluefin.
