B2BINPAY Introduces the B2BINPAY DeFi App: Non-Custodial Crypto Processing for Financial Platforms

The B2BINPAY team is excited to announce the launch of the B2BINPAY DeFi App , a non-custodial, multisignature crypto processing solution built for financial platforms and crypto-native businesses that require full on-chain control.

With this release, B2BINPAY expands beyond custodial processing into programmable, client-controlled infrastructure, enabling businesses to operate crypto payments without surrendering custody.

Launch App

A New Model for Crypto Processing

The B2BINPAY DeFi App introduces a structural shift from traditional custodial processors.

Instead of holding funds on behalf of clients, the DeFi App operates through smart contract accounts deployed on EVM-compatible networks and TRON. Assets remain fully controlled by the client at all times.

Each account is configured with customizable signers and defined signature thresholds, allowing organizations to mirror real-world governance structures on-chain. Critical operations such as payouts, signer updates, or configuration changes require multiple approvals before execution.

This ensures:

• No unilateral fund movement
• On-chain governance enforcement
• Clear operational accountability

A Unified On-Chain Payment Lifecycle

The DeFi App provides a single operational environment to manage the full crypto payment lifecycle.

Businesses can generate both single-currency and multi-currency invoices, each with automatically created on-chain deposit addresses. Every invoice can be tracked in real time, allowing teams to monitor incoming funds without manual reconciliation.

Collected funds can be:

• Pulled from individual invoice addresses
• Aggregated and transferred in batches to a main treasury account

This structure separates operational inflows from treasury balances, helping optimize network fees while maintaining accounting clarity.

All sensitive actions are routed through an approval queue. Transactions remain pending until the required number of signatures is collected, reducing operational risk and internal errors.

Infrastructure-Level API Integration

Beyond the interface, the DeFi App offers API access for platforms integrating crypto processing directly into their backend systems.

Through the API, clients can:

• Create and monitor invoices
• Track deposits
• Initiate fund collection
• Execute payouts
• Monitor approval workflows

This allows the DeFi App to function as a programmable processing layer inside exchanges, brokerages, trading platforms, and digital payment infrastructures.

Security by Architecture

Security is embedded at the protocol level.

The platform does not rely on traditional usernames or passwords. Instead, authentication is performed via wallet signature verification. Users sign a cryptographic message with their wallet, which is validated on-chain to confirm ownership.

Importantly:

• Private keys are never stored or accessed by B2BINPAY
• All smart contract interactions are logged on-chain
• Every operation is transparent and auditable

This reinforces the platform’s non-custodial design while maintaining enterprise-grade operational standards.

Built for Crypto-Native Organizations

The B2BINPAY DeFi App is designed for businesses that operate directly within digital asset markets, including:

• Brokerage platforms and trading intermediaries
• Exchanges and OTC desks
• Crypto-native companies and DAOs
• DeFi projects and payment processors

Core functionality — invoicing, fund collection, approval workflows, and account management — is available at no cost, subject to basic rate limits, making it accessible to both growing and established platforms.

“With the B2BINPAY DeFi App, we are introducing our first crypto processing solution specifically designed for businesses that require full on-chain authority,” says the B2BINPAY team. “This product reflects our vision of transparent, programmable infrastructure where companies define their own operational rules without compromising usability or scalability.”

Expanding the B2BINPAY Ecosystem

With the launch of the DeFi App, B2BINPAY now offers two distinct operational models:

• Enterprise-grade custodial crypto payment processing
• Fully non-custodial, multisignature on-chain processing infrastructure

This dual architecture enables financial platforms to choose the framework that aligns with their governance model, regulatory strategy, and operational needs.
