  2. Validators observe the deposit transaction
  3. Validators submit VoteEthDepositAction votes
  4. Once threshold is reached, funds are credited on Hyperliquid

Use Cases#

Bridge Monitoring#

Track deposit confirmations across the bridge:

def process_VoteEthDepositAction(action):
    user = action.get('user')
    amount = action.get('usd') / 1_000_000
    eth_tx = action.get('ethTxHash')

    print(f"Deposit vote: ${amount:,.2f} for {user[:10]}... (tx: {eth_tx[:10]}...)")

Validator Activity Tracking#

Monitor which validators are actively participating in bridge consensus.

Deposit Latency Analysis#

Track time from Arbitrum transaction to Hyperliquid credit.
