March was a month of expansion, automation, and control.

We continued to push forward on a core theme: giving merchants more ways to accept and move money while strengthening the systems that keep those flows secure, compliant, and reliable at scale.

This month, we expanded payment methods, introduced new processing and payout partners, strengthened fraud defenses, and modernized key parts of our compliance and settlement infrastructure. At the same time, we launched new merchant-facing capabilities that reduce operational overhead and improve day-to-day workflows.

Here’s a closer look at what we shipped.

Broader payment method support and integrations

What we shipped

April marked one of our most significant expansions of payment rails to date. We introduced Cash App as a new pay-in method, giving merchants access to a widely adopted consumer payment network.

Alongside this, we added new infrastructure across the stack:

• A new payout rail for merchant withdrawals
• Additional payment processor coverage
• Expanded card network support, including Discover acceptance

We also extended ACH capabilities and increased limits to support larger transaction volumes.

Why it matters

More payment methods means more successful transactions.

Every additional rail reduces the likelihood of a failed or abandoned payment. By expanding both pay-in and payout coverage, we ensure merchants can serve a broader set of customers while maintaining flexibility in how funds move through the system.

This is especially important for merchants operating across geographies or customer segments with different payment preferences.

Impact

Expanding payment coverage directly translates into fewer lost transactions and stronger revenue capture.

Layered fraud protection across the payment lifecycle

What we shipped

We introduced new safeguards across the payment flow to better detect and prevent fraudulent activity.

This includes improvements to how suspicious traffic is identified, as well as new controls that allow merchants to limit risky behaviors, such as repeated card usage across accounts.

We also tightened how sensitive data is handled across APIs and added additional safeguards to prevent misuse of privileged operations.

Why it matters

Fraud evolves quickly and often targets the weakest layer in the system.

By introducing multiple layers of protection across network traffic, payment behavior, and system access, we raise the cost of attack for bad actors while keeping the experience smooth for legitimate users.

The goal is to block high-risk activity early without introducing friction for real customers.

Impact

These improvements make it harder for bad actors to exploit the system while maintaining a seamless experience for legitimate transactions.

Improved transaction monitoring and operational workflows

What we shipped

We upgraded key parts of our compliance infrastructure, improving how transaction monitoring and review workflows operate.

This includes enhancements to how blockchain transactions are screened, as well as improvements to internal tools that provide real-time visibility into compliance signals.

We also streamlined onboarding workflows by allowing merchants to upload multiple documents at once and improving how verification data is surfaced to compliance teams.

Why it matters

Compliance should be both rigorous and efficient.

Manual workflows slow down onboarding and increase operational overhead. At the same time, weak monitoring systems create risk.

By improving both the visibility and usability of compliance tooling, we help teams move faster without compromising on regulatory requirements.

Impact

These updates allow compliance teams to operate with greater confidence and speed.

Smarter ACH handling and settlement behavior

What we shipped

We improved how ACH withdrawals behave under real-world conditions.

Withdrawals initiated during weekends or holidays now automatically adjust to the next valid banking day instead of failing. We also enforce network limits more clearly, with improved messaging when transactions exceed thresholds.

Why it matters

Payment systems must reflect how banking systems actually operate.

Failed withdrawals due to timing constraints create confusion and support overhead. By aligning system behavior with banking realities, we reduce friction and improve merchants' predictability.

Impact

These improvements make ACH flows more reliable and easier to operate.

New tools for merchants and teams

What we shipped

We introduced a set of new capabilities designed to give merchants more control over their operations and workflows.

These include:

• Bulk invoicing, allowing merchants to send invoices to multiple recipients at once
• Granular role-based access controls for teams
• Improved API key management, including the ability to disable and re-enable keys
• Secure webhook validation via signature verification

We also improved internal tooling, making it easier for teams to manage and search merchant accounts.

Why it matters

As merchants scale, their operational needs become more complex.

They need better controls over access, billing, and integrations. By introducing these capabilities, we reduce the need for custom tooling while improving security and usability across the platform.

Impact

These updates help merchants manage growth without increasing internal complexity.

New blockchain support and system upgrades

What we shipped

We added support for a new EVM-compatible blockchain, expanding Coinflow’s multi-chain infrastructure.

Alongside this, we:

• Upgraded core blockchain libraries
• Simplified real-time architecture by removing legacy components
• Refactored key APIs to better support blockchain-native subscription models

Why it matters

Blockchain ecosystems are evolving rapidly, and infrastructure must keep up.

By supporting additional chains and modernizing core systems, we ensure that Coinflow remains flexible and future-proof as new use cases emerge.

Impact

These upgrades position Coinflow to support a broader set of blockchain-based payment flows.

Eliminating failure points across the platform

What we shipped

April included a wide range of high-impact fixes across payments, onboarding, and infrastructure.

These fixes addressed:

• Payment authentication issues
• Incorrect transaction calculations
• Address validation errors
• Broken onboarding flows
• Incomplete error messaging
• Excessive infrastructure load from redundant calls

We also improved retry logic across critical services and resolved settlement inconsistencies across multiple processors.

Why it matters

Reliability is built through iteration.

Small bugs in payment systems can have an outsized impact—failed transactions, incorrect balances, or broken onboarding flows all degrade trust.

By systematically addressing these issues, we improve the platform's overall stability and predictability.

Impact

Fixing these edge cases ensures the platform performs consistently under real-world conditions.

Looking ahead

April was about expanding what’s possible while strengthening what already exists.

We added new payment methods, improved fraud defenses, modernized compliance workflows, and automated key parts of the settlement lifecycle. At the same time, we continued to invest in infrastructure reliability and in support for blockchain.

The result is a more capable and resilient platform.

As we move forward, our focus remains clear:

Expand payment coverage. Strengthen system reliability. Reduce operational friction.

Because the best payments infrastructure empowers scale.
