WebSocket
This page will help you get started with zkLighter WebSocket server.
Connection
URL: wss://mainnet.zklighter.elliot.ai/stream
You can directly connect to the WebSocket server using wscat:
wscat -c 'wss://mainnet.zklighter.elliot.ai/stream'
Send Tx
You can send transactions using the websocket as follows:
JSON
{
"type": "jsonapi/sendtx",
"data": {
"tx_type": INTEGER,
"tx_info": ...
}
}
The tx_type options can be found in the SignerClient file, while tx_info can be generated using the sign methods in the SignerClient.
Example: ws_send_tx.py
Send Batch Tx
You can send batch transactions to execute up to 50 transactions in a single message.
JSON
{
"type": "jsonapi/sendtxbatch",
"data": {
"tx_types": [INTEGER],
"tx_infos": [tx_info]
}
}
The tx_type options can be found in the SignerClient file, while tx_info can be generated using the sign methods in the SignerClient.
Example: ws_send_batch_tx.py
