Payment Lifecycle

Common merchant flow

Create orderYour system creates an internal payment order and shows a chain-specific address.
Receive txidThe customer provides txid, or your watcher finds candidate transfers.
Verify on-chainCheck status, token contract or mint, recipient, amount and confirmations.
Credit safelyUpdate business state only after the transfer matches order rules.

Deposit monitoring

Use TRON, Ethereum or Solana routes to check transaction state and token transfer details. nodevera keeps the access boundary consistent while your business logic decides when a user balance or order should be credited.

  • TRC20 transfer event checks
  • ERC20 receipt and log validation
  • Solana parsed transaction inspection
  • Retry workflow for delayed index or confirmation state

Withdrawal broadcasting

Your backend should sign transactions with your own key management policy. nodevera receives only the signed transaction payload and broadcasts it to the selected chain route.

  • Signed TRON transaction broadcast
  • Ethereum raw transaction broadcast
  • Solana signed transaction broadcast
  • Result and receipt checks after submission

FAQ

Is this a hosted wallet?No. nodevera is an API access and RPC gateway service, not a wallet custody product.
Can it replace business risk controls?No. It supplies chain data and broadcast access. Your business still owns risk, limits and approval rules.
