RNK RPC Methods

Overview​

This page documents Reactive-specific JSON-RPC methods available in Reactive Network’s (RNK) Geth version. Use them to inspect ReactVM activity (transactions, logs, code, storage), and to query network metadata like subscribers, filters, and origin-chain stats.

Ethereum RPC Methods

Reactive Network supports standard Geth RPC methods. This page lists RNK extensions only.

rnk_getTransactionByHash​

Returns a ReactVM transaction by RVM ID and transaction hash.

Parameters​

  1. rvmId: DATA, 20 Bytes — The ReactVM ID associated with the transaction.
  2. txHash: DATA, 32 Bytes — The hash of the transaction to retrieve.
