CryptoRails accepts crypto deposits and consolidates them into a merchant’s wallet. In the documented integration, the browser detects incoming funds, while a verified server webhook authorises settlement.
I coordinate product delivery across payment flows, EVM and TRON integration, QA, and UI testing. These are the states and failure cases I need to account for in the backlog.
Deposit detection and consolidation
The merchant generates a deposit address for each customer and stores it in its backend. The API key stays on the server. The customer sends funds to that address through the deposit modal or a custom interface.
The browser’s deposit-watch SDK polls the chain and fires onDeposit when funds appear. The callback updates the interface and notifies the merchant backend. The backend requests consolidation; CryptoRails validates the funds and sweeps them into the tenant’s consolidation wallet.
Confirmation and settlement
The gateway tracks consolidation and withdrawal transactions through pending, wait_for_confirmation, confirmed, or failed. These are separate from the browser’s deposit-detection state.
After consolidation confirms, the gateway sends a signed webhook. The merchant backend verifies the HMAC signature against the raw request body, reconciles the address and reference, and credits the ledger once. Duplicate delivery must not create duplicate credit.
EVM and TRON costs
EVM transactions normally use the network’s native coin for gas. TRON token transfers use Energy and may consume Bandwidth. Without enough Energy, a transfer can burn TRX to cover the shortfall.
The gateway applies Energy rental before resource-heavy TRON transactions. Chain-specific resource checks, confirmation conditions, and wallet errors belong in the requirements and QA cases.
Cases the team has to test
- Wrong network, token, recipient, or amount.
- Wallet rejection or a delayed transaction.
- Late RPC or indexing responses.
- Repeated requests and duplicated webhooks.
Each case needs a defined response: wait, retry, reject, or review. The interface must show pending work without suggesting that settlement has completed.
My part in delivery
I contribute to the backlog and roadmap, run Scrum ceremonies, and coordinate the engineering team. I work with the business owner and engineers to define which event permits settlement, what the user sees while waiting, and how retries avoid duplicate credit.
