eth_getTransactionCountHTTP

Returns the account nonce at the selected state. Pending reflects the serving upstream's pending state, not a complete network-wide mempool. Coordinate nonces locally for concurrent sends.

How to use

Pick an API key (or paste one) in the Try it panel.
Fill each parameter (order = params array index).
Send request — live against the gateway; counts toward daily quota.

Parameters

JSON-RPC positional arguments — order matches the array sent in params. Index badges below match array positions.

addressDATA(20B)required

Address to query.

blockQUANTITY|TAGoptional

Hex block number or tag; omitted means latest on clients following the current execution API. Send latest explicitly for compatibility. State is evaluated after that block. Historical state must remain available. Tags and finality guarantees vary by network. In Advanced JSON mode, clients supporting EIP-1898 also accept {"blockHash":"0x...","requireCanonical":true} or {"blockNumber":"0x..."}; do not combine both keys, and use requireCanonical only with blockHash.

Example response

Illustrative example: long hex values and object fields may be shortened for readability. Available fields depend on the network, client, protocol upgrade and transaction type.

Response fields

The result row describes the complete result; other rows describe its object fields or array elements. Indented rows describe nested members. For subscriptions,params.* rows describe later notifications rather than the initial reply.

Field	Type	Description
`result`	`QUANTITY`	Account nonce as hex. On networks supporting EIP-7702, authorizations can also increment it; this is not a lifetime sent-transaction counter.
