Sponsored Bundles

Quasar Builder now supports sponsored bundles. If you send a bundle with a transaction that fails with LackOfFundForGasLimit, we will send the ETH required to cover the gas fees.

The bundle must increase the builder balance in order to cover the cost of sponsoring the bundle.

Example:

{
  "jsonrpc": "2.0",
  "id": 123,
  "method": "eth_sendBundle",
  "params": [
    {
      "txs": ["0x123abc...", "0x456def..."],
      "blockNumber": "0xb63dcd",
      "minTimestamp": 0,
      "maxTimestamp": 1615920932
    }
  ]
}

Example Response:

{
  "jsonrpc": "2.0",
  "id": "123",
  "result": {
    null
  }
}
