RPC API Reference - StableNet

All JSON-RPC methods available on StableNet nodes, organized by namespace.

Connection Endpoints

Transport	URL
HTTP RPC	`https://api.test.stablenet.network`
WebSocket	`wss://api.test.stablenet.network/ws`

WebSocket is required for eth_subscribe methods.

eth Namespace

Network and Fees

Method	Description
`eth_chainId`	Returns the chain ID
`eth_gasPrice`	Returns gas price for legacy transactions
`eth_maxPriorityFeePerGas`	Returns priority fee enforced by GovValidator contract
`eth_feeHistory`	Returns historical fee data
`eth_syncing`	Returns node synchronization status

In StableNet with Anzeon WBFT enabled, eth_maxPriorityFeePerGas returns the gas tip value set by the GovValidator contract — not an oracle estimate.

Blocks and State

Method	Description
`eth_blockNumber`	Returns current block number
`eth_getBalance`	Returns account balance
`eth_getCode`	Returns contract bytecode
`eth_getStorageAt`	Returns a specific storage slot value
`eth_getProof`	Returns Merkle proof for account and storage
`eth_getBlockByNumber`	Returns a block by number
`eth_getBlockByHash`	Returns a block by hash
`eth_getTransactionByHash`	Returns a transaction by hash
`eth_getTransactionReceipt`	Returns a transaction receipt

Transactions

Method	Description
`eth_sendTransaction`	Signs and submits a transaction (requires unlocked account)
`eth_sendRawTransaction`	Submits a pre-signed transaction
`eth_signTransaction`	Signs a transaction without submitting
`eth_fillTransaction`	Fills missing default fields in a transaction
`eth_estimateGas`	Estimates gas required for a transaction
`eth_call`	Executes a read-only call without state changes

Fee Delegation Extensions

StableNet extends the standard API with fee delegation signing methods.

Method	Description
`personal_signRawFeeDelegateTransaction`	Appends fee-payer signature using password-unlocked account
`eth_signRawFeeDelegateTransaction`	Appends fee-payer signature using already-unlocked account

Submit the resulting signed transaction via eth_sendRawTransaction. Gas costs are charged to the fee payer.

eth Filter Methods

Polling-Based Filters

Method	Returns	Description
`eth_newFilter`	Filter ID	Creates a log filter with specified criteria
`eth_newBlockFilter`	Filter ID	Creates a filter for new block hashes
`eth_newPendingTransactionFilter`	Filter ID	Creates a filter for pending transactions
`eth_getFilterChanges`	Logs / Hashes	Returns changes since last poll
`eth_getFilterLogs`	Logs array	Returns all logs matching the filter
`eth_getLogs`	Logs array	One-time log query without a persistent filter
`eth_uninstallFilter`	Boolean	Removes a filter

Polling filters expire after 5 minutes of inactivity. Each eth_getFilterChanges call resets the timer.

WebSocket Subscriptions

Method	Event Type	Description
`eth_subscribe("newHeads")`	Block header	Fires on each new block
`eth_subscribe("logs", criteria)`	Log	Fires for logs matching criteria
`eth_subscribe("newPendingTransactions")`	Tx hash	Fires for each pending transaction
`eth_unsubscribe`	Boolean	Cancels a subscription

FilterCriteria fields for log subscriptions:

Field	Type	Description
`fromBlock`	`string` (block tag or hex)	Start block (`null` = latest)
`toBlock`	`string` (block tag or hex)	End block (`null` = latest)
`address`	`string \| string[]`	Contract address(es) to filter
`topics`	`string[][]`	Topic filters (AND across positions, OR within a position)

Topic matching: up to 4 positions; null at a position matches any value.

txpool Namespace

Method	Description
`txpool_content`	Lists all pending and queued transactions
`txpool_contentFrom`	Lists transactions from a specific address
`txpool_status`	Returns pending/queued counts
`txpool_inspect`	Returns human-readable transaction pool summary

Transaction states:

pending — eligible for inclusion in the next block
queued — waiting due to nonce gaps or insufficient balance

web3 Namespace

Method	Description
`web3_clientVersion`	Returns the node client version string
`web3_sha3`	Computes the Keccak-256 hash of input data

istanbul Namespace

Available only when Anzeon WBFT consensus is active.

Method	Description
`istanbul_nodeAddress`	Returns the signer node address
`istanbul_getCommitSignersFromBlock`	Returns proposer and commit signers for a block number
`istanbul_getCommitSignersFromBlockByHash`	Returns signers for a block hash
`istanbul_getValidators`	Returns the current validator list
`istanbul_getValidatorsAtHash`	Returns validators at a specific block hash
`istanbul_status`	Returns round and sealer statistics

personal Namespace

personal is disabled on public RPC endpoints. Available on local nodes only.

Method	Description
`personal_newAccount`	Creates a new account
`personal_listAccounts`	Lists managed accounts
`personal_unlockAccount`	Unlocks an account with password
`personal_lockAccount`	Locks an account
`personal_sendTransaction`	Signs and sends a transaction using password
`personal_signTransaction`	Signs a transaction using password
`personal_sign`	Signs arbitrary data using password
`personal_importRawKey`	Imports a private key
