eth_getTransactionCount - zkSync RPC Method

Get account nonce on zkSync Era. Essential for transaction ordering for RWA tokenization ($1.9B, 25% market share), hyperchain deployment via ZK Stack, and cross-chain DeFi.

Returns the number of transactions sent from an address on zkSync Era (the nonce).

Use Cases

  • Transaction building - Get correct nonce for new transactions
  • Account analysis - Count total outgoing transactions
  • Nonce management - Handle pending transaction queues
  • Wallet operations - Prepare transactions for RWA tokenization ($1.9B, 25% market share), hyperchain deployment via ZK Stack, and cross-chain DeFi

Python
from web3 import Web3

w3 = Web3(Web3.HTTPProvider('https://api-zksync-era-mainnet-full.n.dwellir.com/YOUR_API_KEY'))

address = '0x5AEa5775959fBC2557Cc8789bC1bf90A239D9a91'
nonce = w3.eth.get_transaction_count(address)
print(f'Nonce: {nonce}')

# Get pending nonce
pending_nonce = w3.eth.get_transaction_count(address, 'pending')
print(f'Next nonce: {pending_nonce}')

eth_getStorageAt

Read contract storage on zkSync Era. Essential for analyzing contract state for RWA tokenization ($1.9B, 25% market share), hyperchain deployment via ZK Stack, and cross-chain DeFi.

eth_accounts

Returns a list of addresses owned by the client on zkSync Era. Typically returns an empty array on public RPC endpoints.
