Equillar has developed an automated three-phase system to verify payment capacity for investment contracts, ensuring investor payments are processed reliably. The system utilizes scheduled commands, asynchronous messaging via Symfony Messenger, and direct blockchain interaction with Stellar smart contracts. Initially, eligible contracts in ACTIVE, FUNDS_REACHED, or PAUSED states are identified and queued for verification.

Asynchronous workers then process these requests, delegating business logic to specialized services. The core verification occurs on the Stellar blockchain, where smart contracts calculate reserve balances against pending investor claims. If deficits are detected, contracts are automatically blocked and administrators are alerted with exact funding shortfalls.

This hybrid approach combines traditional PHP framework flexibility with blockchain transparency and immutability. The system provides complete traceability through recorded blockchain transactions and maintains historical verification data for reporting and analysis. Key advantages include scalability through asynchronous processing, resilience against individual verification failures, and clear separation of concerns between system components.

This solution demonstrates how financial technology platforms can leverage blockchain technology to enhance payment security and operational transparency in investment management systems.
