Introduction

The GENIUS Act has established a compliance baseline for stablecoins in the United States. Full reserve backing, mandatory audits, and AML controls now define the minimum conditions for issuers. For policymakers, this marks a milestone. For institutions, it is only the beginning.

Compliance demonstrates that a stablecoin is legal to operate. It does not prove that the system is resilient, enforceable, or safe to integrate into institutional workflows. Redemption logic can still fail under stress, sanctions lists may not apply consistently across functions, and oracles remain vulnerable to manipulation. Each of these gaps can trigger regulatory findings, reputational loss, or direct balance sheet exposure.

For procurement and risk officers, these are not abstract concerns. They are exactly the kinds of issues that delay onboarding, stall partnerships, or kill promising integrations outright. Institutions need more than a passing GENIUS compliance audit. They need evidence that stablecoin infrastructure can withstand operational pressure, enforce controls consistently, and provide regulator-ready assurance.

This article builds on our earlier GENIUS Act analysis and examines why statutory compliance is necessary but insufficient for institutional adoption. It highlights the structural risks that remain across stablecoin systems and how Cantina helps issuers and integrators close those gaps.

The Limits of GENIUS Compliance

GENIUS requires issuers to hold fully-backed reserves, undergo audits, and comply with AML/CFT obligations. While these obligations bring stablecoins closer to bank-like regulatory expectations, they do not guarantee operational soundness.

An issuer can demonstrate monthly reserve disclosures and pass an external audit while still operating contracts with exploitable access controls or fragile redemption logic. In practice, compliance signals legality, not security.

From Cantina’s assessments, recurring categories of weakness appear regardless of whether a stablecoin is fiat-backed, overcollateralized, or yield-bearing:

• Bypassable access controls that allow privileged roles to renounce safeguards or alter state in unexpected ways.
• Fragile redemption mechanics where queues saturate or fragment, producing denial-of-service risks during volatility.
• Incomplete blacklist enforcement in which transfers, redemptions, and bridging functions fail to consistently apply sanctions lists.
• Oracle fragility caused by missing staleness checks, single-source dependencies, or edge-case circuit misbehavior.
• Deviation from ERC specifications such as ERC-7540 or ERC-4626, reducing interoperability and complicating independent audits.

Each of these gaps introduces risks that GENIUS compliance alone does not remediate.

Institutional Implications of Residual Gaps

Financial institutions must evaluate stablecoins not only as legal instruments, but as operational dependencies. If redemption logic fails under stress, liquidity mismatches propagate directly into balance sheets. If blacklist enforcement is incomplete, supervisory findings or reputational harm follow. If oracles malfunction, parity breaks can ripple through multiple protocols and trading venues.

For procurement and vendor risk organizations, these weaknesses translate into three forms of exposure:

1. Operational risk from settlement delays or redemption failures.
2. Regulatory risk from sanctions or AML enforcement actions.
3. Systemic risk from correlated failures across integrated financial platforms.

This is why GENIUS-compliant issuers still fail to meet institutional readiness until they can demonstrate that these control gaps are closed and independently validated.

Patterns from Cantina’s Stablecoin Audits

Across multiple stablecoin ecosystems, our high-signal audits consistently surface the same failure patterns:

• Administrative controls that can be renounced without enforced transfer of authority, leaving contracts in ambiguous states.
• Redemption logic that fails to prioritize requests, allowing resource starvation and blocking under load.
• Blacklist functions that are applied only to primary transfer methods, leaving loopholes in redemptions, bridging, or administrative actions.
• Oracle integrations without sufficient staleness checks, enabling replay or manipulation during volatility.
• Divergence from standards that complicates interoperability, such as mis-implementations of ERC-4626 affecting composability with DeFi protocols.

These are not hypothetical risks. They have been observed in production deployments of systems with billions of dollars in circulating supply.

The Path to Institutional Readiness

GENIUS has created a compliance baseline. The next phase requires issuers and infrastructure providers to demonstrate controls that go beyond legality to enforce operational resilience.

Cantina’s work with stablecoin organizations focuses on exactly this:

• High-signal security audits targeting permission boundaries, redemption mechanics, reserve flows, and blacklist logic.
• Stress testing under simulated Treasury drawdowns, redemption surges, and queue overloads.
• Oracle and proof validation to ensure reserve attestations and dynamic pricing behave correctly across edge cases.
• Compliance-aligned documentation that translates technical controls into regulator- and auditor-ready evidence.

This dual focus on technical resilience and auditability is what institutions require when integrating stablecoins into payment systems, settlement infrastructure, or tokenized fund structures.

Operational Priorities for Issuers and Integrators

Stablecoin issuers and the organizations building with them should now treat the following as minimum operational priorities:

1. Onchain or cryptographically attested reserve reporting validated by independent third parties.
2. Redemption logic engineered for priority enforcement and resilience under stress events.
3. Complete AML and sanctions enforcement across all system functions, including bridges and wrappers.
4. Governance and upgrade processes documented at audit-grade detail.
5. Continuous monitoring and remediation of integration risks across partner ecosystems.

These requirements align with the expectations of procurement, operational risk, and compliance organizations.

Conclusion

The GENIUS Act has placed stablecoins firmly within the scope of regulated finance. But compliance does not equal resilience. Institutions will adopt stablecoins only when they see evidence of enforceable controls that extend beyond statutory requirements.

As we argued in our previous GENIUS Act analysis, regulation marks the start of institutional adoption. The next phase depends on issuers and integrators closing the persistent control gaps that undermine operational stability and compliance enforcement.

Cantina’s role is to help organizations achieve that standard. Through high-signal audits, stress testing, and compliance-aligned documentation, we support the deployment of stablecoins that are not only compliant, but also institutionally defensible.
