Guardrail Launches Proactive Security Model for Stablecoins

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

Rain, fresh off $250M Series C, deploys unified detection-to-response framework to further protect 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 crucial step between vulnerability exposure and live attacks.

Rain, the global stablecoin payments platform for enterprises, neobanks, and platforms, recently deployed this unified security framework within its smart contracts and wallets used for settlement with Visa, further improving security for millions of purchases in over 150 countries.

Stablecoin transaction volumes crossed $27.6 trillion in 2024, surpassing Visa and Mastercard combined. As traditional finance accelerates its move onchain, the security challenges and unique risks it poses are widening the gap.

The blockchain industry lost over $3.4 billion 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 take place in production environments through compromised keys, operational failures, and runtime exploits that static code review cannot anticipate and prevent.

Why Post-Deployment Security Matters for Stablecoins

Stablecoin infrastructure operates differently from typical DeFi protocols. When software events translate directly into payment outcomes across 150+ countries, a configuration error or a malicious transaction pattern can cause immediate user harm, with limited options for reversal.

Each application of stablecoin technology by geography, financial application, underlying assets, and wallet infrastructure brings incredible potential while simultaneously growing security risk possibility for unique attack vectors. Industry data shows that off-chain incidents compromised keys, phishing, and operational failures now represent the majority of funds lost, underscoring the need for security extending the attacking surface to: onchain activity, offchain integrations, API dependencies, and user-facing entry points.

“As Web3 matures, risk management and proactive security measures that leading institutions have built into traditional products need to be offered when transacting with stablecoins, like their fiat counterparts. Unifying risk discovery, real-time detection and managed automated response is the gold standard we’re excited to be shaping for our industry,” said Samridh Saluja, CEO of Guardrail.

How the Framework Operates

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

When an incident is flagged, alerts route directly into managed response workflows developed in collaboration with Cantina, a Web3 security firm. Response operates through 24/7 triage, pre-built playbooks across technical and governance tracks, and escalation paths with defined ownership. Evidence is captured throughout proactively, resulting in an informed security posture.

Institutional-Grade Security for Onchain Finance

As stablecoins move into enterprise payments and institutional custody, security expectations shift. Partners evaluating onchain infrastructure ask direct questions: Who owns containment? How is authority structured? What evidence trail exists? 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 governed incident workflows. Escalations route to named owners. Containment follows documented playbooks. Evidence trails support both internal review and partner diligence.

“Our enterprise partners rely on Rain to protect real-world payment flows totaling billions of dollars annually. Integrating Guardrail’s real-time monitoring and Cantina’s managed response capabilities enhances our ability to detect anomalies early and act decisively,” said Charles Yoo-Naut, CTO and Co-founder of Rain. “This is an important addition to the broader set of onchain security partners we rely on to safeguard our ecosystem.”

The integrated detection and response model is a template for protocols operating stablecoin infrastructure, custody flows, enterprise payments, and onchain financial products.

Nexo Partners with Bakkt for US Crypto Exchange and Yield Programs

Nexo Partners with Bakkt for US Crypto Exchange and Yield Programs

TLDR

  • Nexo is relaunching its crypto services in the United States after more than three years of absence.
  • The platform will offer yield programs, a spot exchange, and crypto-backed credit lines to US users.
  • Nexo has partnered with Bakkt to provide the trading infrastructure for its US operations.
  • The company’s return is driven by improved regulatory clarity for digital assets in the US.
  • Nexo’s new US operations will be based in Florida and run by an announced management team.

Crypto platform Nexo is set to return to the United States after more than three years. The company paused its operations in 2022 due to regulatory concerns. Now, with clearer guidelines in place, Nexo aims to offer crypto services including yield programs, a spot exchange, and more.

Nexo Partners with Bakkt for Trading Infrastructure

Nexo’s trading infrastructure will be powered by Bakkt, a US-based digital asset platform. Bakkt primarily serves institutional clients but will help Nexo build its new US offering. Eleonor Genova, Nexo’s head of communications, confirmed that the platform will provide both flexible and fixed-term yield programs.

The platform will also feature crypto-backed credit lines and a loyalty program for US customers. Nexo’s management team will operate the new venture from Florida, with plans to announce the team soon. Genova emphasized that all services will be offered through partnerships with licensed US providers.

After leaving the US market in late 2022, Nexo now sees improved regulatory clarity for digital assets in the country. The company originally withdrew due to what it called an unfriendly regulatory environment under former SEC chair Gary Gensler. Nexo’s “Crypto Earn” program, which lets users earn interest on their crypto holdings, was a key issue in the company’s exit.

Nexo settled with the SEC in 2023, agreeing to pay $45 million for failing to register its interest-bearing program. The company later shut down the program for US users, marking the end of its earlier US operations. Despite these setbacks, Nexo now believes the regulatory landscape is more favorable for blockchain businesses.

Nexo’s Relaunch and US Crypto Regulatory Landscape

Nexo’s return comes as the US continues to work on crypto regulations. The House recently passed the CLARITY Act, but the Senate has yet to move it forward. Patrick Witt, a White House crypto advisor, called for compromises to pass crypto-related legislation before the 2024 elections.

This renewed effort to regulate crypto coincides with Nexo’s own regulatory framework. Genova stated that the new US operations are compliant with US securities laws. The company hopes to provide a stable platform for crypto users amid ongoing regulatory discussions.

Nexo’s rebooted platform will rely on third-party advisory services registered with the SEC. This ensures that the services offered are in line with applicable securities laws. The crypto exchange aims to establish itself as a trusted platform for US users after its previous exit.

Nexo Relaunches Crypto Platform in the United States

Published

SEC, United States, Nexo

Nexo is set to relaunch its digital asset services and crypto exchange platform in the US on Monday, more than three years after it left the market following battles with federal and state regulators.

Now, citing improved regulatory clarity for digital assets in the US, the rebooted Nexo platform will offer flexible and fixed-term yield programs, a spot cryptocurrency exchange, crypto-backed credit lines and a loyalty program for US users, Nexo head of communications Eleonor Genova told Cointelegraph.

The platform’s trading infrastructure will be provided by Bakkt, a US-based digital asset platform focused on serving institutional clients. Genova said:

“Nexo’s US offering is structured through partnerships with appropriately licensed US service providers. Certain services are made available via a third-party Securities and Exchange Commission-registered (SEC) investment adviser, which provides advisory services under applicable US securities laws.”

The new US operations will be based in Florida and run by a management team to be announced soon, according to the company.

Nexo first announced plans to re-enter the US during an exclusive event in April 2025, which featured Donald Trump Jr., the son of US President Donald Trump, as a keynote speaker. At the event, Trump Jr. described crypto as the future of finance.

2022 exit cited regulatory uncertainty under Gensler regime

The company said it had decided to exit the US out of necessity after engaging in “good faith” conversations with US state and federal regulators over 18 months that did not move the needle.

“It is now unfortunately clear to us that despite rhetoric to the contrary, the US refuses to provide a path forward for enabling blockchain businesses,” the company said at the time.

Nexo’s “Crypto Earn” program, which allowed users to earn compounding interest on select cryptocurrencies loaned to the platform, was a major point of contention between the SEC and the company.

In January 2023, Nexo agreed to a $45 million settlement with the SEC over failing to register its interest-bearing crypto rewards program with the regulator. The company also settled a $22.5 million multi-state securities settlement related to the earn interest program.

The company shuttered its Crypto Earn program for US users one month later.

Washington mulls crypto “clarity”

Nexo’s market reentry comes amid efforts in Washington to pass a bill defining how US market regulators will police crypto. The House passed a similar bill, the CLARITY Act, in July, but the effort has stalled as the Senate Banking Committee has yet to gather enough bipartisan support to advance it.

White House crypto adviser Patrick Witt said on Friday that both sides must compromise on the issue and push for passage before November’s midterm elections. Contributing to the stalemate are concerns voiced by crypto industry executives, which US Treasury Secretary Scott Bessent believes have negatively impacted the industry, he told CNBC on Friday.

A White House-brokered meeting last week between crypto and banking industry representatives to reach an agreement on stablecoin provisions in the market structure bill was described as “productive,” but remains unresolved.
