userLeverageUpdates

Stream live leverage updates for specific users.

New endpoint - this endpoint is not a part of original Hyperliquid API and is added by us for builder convenience.

Subscribe

    "method": "subscribe",
    "subscription": {
        "type": "userLeverageUpdates",
        "addresses": ["0x742d35Cc6634C0532925a3b844Bc9e7595f7F2e2"]
    }

Update data format

Updates are batched per block, sorted by tx_index. This stream includes all three update types: leverage changes, isolated margin updates, and top-up isolated margin updates — combined and interleaved in block order for the subscribed addresses.

Reconnection Note: When reconnecting with a session, replay and live events may overlap. Deduplicate using (time, tx_index) - skip updates where this tuple is at or before your last processed update. See Session Management for details.

For isolated margin updates only (without leverage changes), see userIsolatedMarginUpdates.

Leverage update

Sent when a user changes their leverage setting (updateLeverage action).

      "is_cross": true,
      "leverage": 10,
      "tx_index": 0
    }
  ]
}

Isolated margin update

Sent when a user adds or removes isolated margin on a position (updateIsolatedMargin action).

{
  "type": "userLeverageUpdates",
  "seq": 2,

{
  "type": "userLeverageUpdates",
  "seq": 3,
  "cursor": 1704067202000,

Examples

Javascript

const WebSocket = require('ws');

const ws = new WebSocket(`wss://api.hydromancer.xyz/ws?token=${process.env.HYDROMANCER_API_KEY}`);

ws.on('message', (data) => {
    const msg = JSON.parse(data);

    if (msg.type === 'connected') {
        ws.send(JSON.stringify({
            method: 'subscribe',
            subscription: {

            }
        }));
    } else if (msg.type === 'ping') {
        ws.send(JSON.stringify({ type: 'pong' }));
    } else if (msg.type === 'userLeverageUpdates') {
        for (const update of msg.updates) {

                console.log(`${update.coin} leverage=${update.leverage} is_cross=${update.is_cross}`);
            } else if (update.update_type === 'isolated_margin') {
                console.log(`${update.coin} is_buy=${update.is_buy} ntli=${update.ntli}`);
            } else if (update.update_type === 'top_up_isolated_margin') {
                console.log(`${update.coin} target_leverage=${update.target_leverage}`);

        }
    }
