Método RPC `eth_getTransactionCount`

MegaETH nodes use a ~15-day pruning window for historical state data. Querying the transaction count at a block older than ~15 days (1,296,064 blocks) may fail because the required account history has been pruned. For more details, see the MegaETH Pruning Policy.
