JSON-RPC Reference

Ethereum JSON-RPC and WebSocket methods on ZENANET, with parameters and request/response examples

ZENANET runs an Ethereum JSON-RPC server and a Cosmos SDK REST server side by side. Both expose the same chain state through different interfaces. This page catalogs the JSON-RPC and WebSocket side. Click any row to expand its parameters and examples. The Cosmos REST side is on the REST API Reference page.

Explorer-style routes such as /transactions, /token-transfers, or /search belong to the Blockscout API v2, not to the node. They only exist once a Blockscout instance is indexing the node over JSON-RPC (including the debug namespace). Everything below is served by the node itself.

Transactions

EVM transactions use a 0x hash. Every EVM transaction is also wrapped in a Cosmos transaction (MsgEthereumTx), so it has a second, 64-character HEX hash. Cosmos-hash lookups live on the REST API Reference.

POSTeth_getTransactionByHashTransaction by hashevm.zena-ai.io

A mined transaction has blockNumber and blockHash filled in. A transaction still in the mempool is returned with those set to null. Unknown hashes return result: null.

Parameters

NameInDescription
hashrequiredparams[0]0x-prefixed 32-byte transaction hash

Request

curl -s https://evm.zena-ai.io -H 'Content-Type: application/json' -d '{
  "jsonrpc": "2.0", "id": 1,
  "method": "eth_getTransactionByHash",
  "params": ["0x<txhash>"]

}
POSTeth_getTransactionReceiptReceipt: status, gas used, logsevm.zena-ai.io

status is 0x1 for success and 0x0 for a revert. Contract-creation transactions have contractAddress set. The logs array holds emitted events such as ERC-20 Transfer.

Token Transfers and Logs

ERC-20 transfers are found through the Transfer event. The full history of one token is eth_getLogs with address set to the token. The list of transactions for one address is not available over JSON-RPC. Use the REST tx search for that. Plain EVM value transfers and Cosmos MsgSend emit no logs and are only visible there.

POSTeth_getLogsTransfer logs of a token (the core query)evm.zena-ai.io

Put the token contract in address and the Transfer signature in topics[0]. topics[1] is from and topics[2] is to. With default node settings a single call is capped at 10,000 blocks and 10,000 logs, so scan long histories in chunks.

Parameters

Real-time and Filters

WebSocket subscriptions use wss://evm.zena-ai.io/ws. For HTTP polling, create a filter with eth_newFilter and poll eth_getFilterChanges. A node keeps at most 200 filters, and idle filters expire.

Running Your Own Node

[json-rpc]
enable = true
api = "eth,net,web3,txpool,debug"   # default is eth,net,web3
enable-indexer = true               # recommended for fast lookups by tx hash
ws-origins = ["127.0.0.1", "localhost", "app.example.com"]

[api]
enable = true
enabled-unsafe-cors = true          # only if browsers call REST :1317 directly

With enable-indexer off, eth_getTransactionByHash falls back to a CometBFT tx_search on every call. This gets slower as the chain grows, so always enable it on public RPC nodes.
