Platform Specifications

Technical overview of PayCow's non-custodial blockchain monitoring and transaction verification infrastructure.

Multi-Chain RPC Node Polling

The settlement engine monitors TRON and Ethereum networks through direct JSON-RPC log queries and node event polling on smart contract transfer events, ensuring deterministic detection across network states.

  • Deterministic event filtering by contract address and topic hashes across TRC-20 and ERC-20.
  • Immune to dropped connections associated with raw websocket streams.
  • Continuous block tracking with state-persisted indexing.

Deterministic Confirmation Finality

Transactions require on-chain block confirmations (solidified blocks on TRON, 12 confirmed blocks on Ethereum) prior to ledger finalization, eliminating risks associated with transient chain reorganizations.

  • Immutable confirmation thresholds verified against on-chain block receipts.
  • Asynchronous background verification workers.
  • Cryptographic validation of transfer recipients and token decimals.

Non-Custodial Direct Routing

PayCow does not custody digital assets or manage private keys. Invoices route buyer transfers directly to merchant-provided external destination addresses.

  • Support for exchange deposit addresses (Binance, Bybit, OKX) and cold wallets.
  • Unique address serial numbers for dynamic API routing.
  • Direct settlement without intermediary pool wallets or withdrawal delays.

RESTful API Architecture

Integrate invoice generation and transaction status tracking directly into enterprise backends using standardized HTTP APIs.

  • Stateless authentication using API Key and Secret headers.
  • Dynamic session creation with custom metadata and serial address selection.
  • Comprehensive status polling endpoints for real-time ledger synchronization.

Automated Webhooks & Event Stream

Asynchronous HTTPS POST callbacks deliver real-time transaction updates directly to merchant endpoints upon on-chain status transitions, removing the need for continuous polling.

  • Cryptographic verification using HMAC-SHA256 signature headers (x-paycow-signature).
  • Configurable endpoint URL with dashboard-driven secret rotation and event delivery logs.
  • Automated retry mechanism for transient network faults and non-2xx HTTP responses.
  • Standardized event payloads covering detection, block confirmation, and session expiry.
