Use one of these when Astralane requires a valid tip in the transaction.

sendTransaction

Use POST /astralane with the official Astralane JSON-RPC body:

sendTransaction JSON-RPC

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "sendTransaction",
  "params": [
    "<base64-transaction>",
    {
      "encoding": "base64",
      "skipPreflight": true
    },
    {
      "mevProtect": true
    }
  ]
}

Common options:

• Query params: api-key, mev-protect, swqos-only

• params[1].encoding: recommended base64

• params[1].skipPreflight: recommended true

• params[2].mevProtect: optional

sendBundle

Use POST /astrln-submit-bundle or POST /astralane with method: "sendBundle":

sendBundle JSON-RPC

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "sendBundle",
  "params": [
    [
      "<base64-transaction-1>",
      "<base64-transaction-2>"
    ],
    {
      "encoding": "base64",
      "mevProtect": true,
      "revertProtection": false
    }
  ]
}

• Maximum 4 transactions

• revertProtection is optional

sendBatch

Use POST /astrln-submit-batch or POST /astralane with method: "sendBatch":

sendBatch JSON-RPC

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "sendBatch",
  "params": [
    [
      "<base64-transaction-1>",
      "<base64-transaction-2>"
    ],
    {
      "mevProtect": true
    }
  ]
}

• Maximum 25 transactions

• Astralane documents sendBatch as available on request

• Requirement: every transaction must include a valid Astralane tip

sendIdeal

Use POST /astrln-submit-ideal or POST /astralane with method: "sendIdeal":

sendIdeal JSON-RPC

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "sendIdeal",
  "params": [
    [
      "<base64-high-tip-low-fee-transaction>",
      "<base64-low-tip-high-fee-transaction>"
    ]
  ]
}

sendIdeal expects exactly 2 transactions.

getNonce

Use GET /astrln-get-nonce or POST /astrln-get-nonce when you need Astralane's getNonce flow for sendIdeal.

Example JSON-RPC call forwarded upstream:

getNonce JSON-RPC

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "getNonce",
  "params": [
    "<api-key>"
  ]
}

Example helper response:

getNonce response

{
  "nonce": "<hash>",
  "nonceAccount": "<pubkey>",
  "nonceAuthority": "<pubkey>"
}
