Overview

This page provides an overview of the RPC methods specific to the Reactive Network's Geth version, essential for interacting with nodes and ReactVMs within the Reactive Network (RNK). These methods enable transaction retrieval, log access, callback information, and more. Below, you will find a detailed description of each method, including its parameters, usage examples, and responses.

rnk_getTransactionByHash

Returns the details of a transaction for the specified ReactVM 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.

Example Parameters:

rnk_call

Simulates a contract method call without an actual transaction, using the blockchain state at a specific transaction or block.

Parameters

1. rvmId: DATA, 20 bytes — The unique identifier of the RVM.
2. args: OBJECT — The transaction arguments, including the contract method and parameters. Should include:
   • to: DATA, 20 bytes — The address of the contract.
   • data: DATA — The call data, representing the method and parameters.
   • from: DATA, 20 bytes, (optional) — The address from which the call is simulated. If omitted, the simulation assumes the call is made from an empty address (0x000...).
   • gas: QUANTITY, (optional) — The maximum amount of gas allowed for the simulation. If omitted, a default value is used.
   • gasPrice: QUANTITY, (optional) — The price of gas (in RVM-specific units) for the simulation.
   • value: QUANTITY, (optional) — The amount of tokens (e.g., Ether) to send along with the call. For non-payable functions, this should be 0.
3. txNumberOrHash: QUANTITY | TAG — Specifies the block number or hash to use for simulating the call. Accepts either a block number (QUANTITY) or a tag ("latest", "earliest", "pending").
