eth_getTransactionCount

eth_getTransactionCount JSON-RPC reference for MegaETH.

Summary

Returns the number of transactions sent from an address at a given block.

The public MegaETH endpoint supports this method. The standard, node, and gateway layers below identify behavior that differs from a generic Ethereum endpoint.

Parameters

address Address REQUIRED

Target account address.


block string

Hex block number or tag (latest, safe, finalized, earliest, pending). The default is "latest".

Result

result Quantity

Transaction count at the requested block. The method returns a zero quantity for both unknown accounts and accounts with zero transactions.

Comparison with Ethereum Standard JSON-RPC

Ethereum Standard

The canonical Ethereum method uses the parameter and result contract documented above, including the stated null, false, or zero-value semantics where applicable.

MegaETH Node Behavior

The node returns the account nonce at the selected state. Unknown accounts and accounts that have not sent transactions both produce a zero quantity.

MegaETH Public Gateway

For latest or pending, the gateway rewrites to mega_getAccountInfo, treats pending as latest, and can return a fresh cached nonce immediately. Historical selectors bypass the account cache; a nonce read in the same outer batch as submissions need not include those submissions.

Errors

The | Scope | column distinguishes method failures from gateway policy errors.
