Dedicated RPC for Exchanges: Deposits, Withdrawals and Reconciliation

Separate the three workloads

An exchange uses RPC to detect deposits, submit signed withdrawals and reconcile on-chain activity with its ledger. These workloads need different checks. A deposit scanner needs complete processing and a finality policy. A withdrawal service needs a durable record of what it submitted. Reconciliation needs reproducible queries against an identified chain state.

Dedicated capacity can isolate these requests from other customers' traffic. It does not replace the exchange's accounting controls or make an incomplete scanner reliable.

Make deposit processing recoverable

Store the last fully processed block height and hash. Advance that checkpoint only after the corresponding application work is committed. If fetching or processing a block fails, retain enough state to retry without crediting the same deposit twice.

Define the supported deposit paths for each asset. A successful transaction is not automatically a deposit to your customer: verify the destination, asset identity, amount and any required customer reference. For token transfers, validate the relevant contract and event rather than trusting a matching event signature alone.

On Ethereum, eth_getTransactionReceipt provides execution status and logs. A successful receipt still does not establish finality or validate your asset-accounting rules. Use the Ethereum JSON-RPC documentation when defining the exact checks.

Treat broadcast timeouts as unresolved

Persist the withdrawal identifier, signed bytes and transaction hash before submission. Keep signing keys outside the RPC host.

If submission times out, do not immediately create a replacement payment. Check the transaction's status and use a network-specific recovery policy. Rebroadcasting the same signed transaction is different from constructing a new transaction. Any replacement procedure must remain tied to the original withdrawal record and account for nonce or sequence handling.

An acknowledgement from an RPC endpoint is not the same as successful, finalized execution.

Specify the history you actually need

For reconciliation, record the block reference used by each query. Comparing balances fetched at different moving tips can produce discrepancies that are difficult to investigate.

Historical balances, transaction receipts and execution traces are separate requirements. Do not assume that an endpoint described as "archive" supplies every method across every historical range. Test representative queries at the oldest required heights; our archive-node guide explains the distinction.

Scope the deployment around recovery

Ask for the required methods, retention, access controls and backup capacity explicitly. Test recovery while live deposit processing continues, and agree who handles node maintenance versus application incidents. Use the node-provider checklist to compare the same requirements across deployment options.

DTEAM can scope dedicated RPC and archive nodes for networks beyond those currently listed on our site. Send us your chains, supported deposit paths and historical-query requirements to discuss a dedicated-node deployment for your integration.
