Astralane routes

Send the JSON-RPC body Astralane’s own submit-transactions reference defines. Do not add api-key; ThorNode supplies it. The response body is Astralane’s, unchanged.

Route	Method	Transactions	Minimum tip
`POST /astralane`	`sendTransaction` (also accepts `sendBundle`, `sendBatch`, `sendIdeal`)	1	10,000 lamports
`POST /astrln-submit-bundle`	`sendBundle`	1–4	10,000 lamports in at least one transaction
`POST /astrln-submit-batch`	`sendBatch`	1–25	10,000 lamports each
`POST /astrln-submit-ideal`	`sendIdeal`	exactly 2	10,000 lamports
`GET` / `POST /astrln-get-nonce`	`getNonce`	—	—

Query parameters mev-protect and swqos-only are forwarded to Astralane. sendPaladin returns 410.

sendTransaction

POST /astralane

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "sendTransaction",
  "params": [
    "<BASE64_SIGNED_TRANSACTION>",
    { "encoding": "base64", "skipPreflight": true },
    { "mevProtect": true }
  ]
}

params[2] is optional. Response: {"jsonrpc":"2.0","id":1,"result":"<SIGNATURE>"}.

sendBundle

Up to 4 transactions executed in order; Astralane reverts the whole bundle if a member fails. At least one transaction must pay a qualifying 10,000-lamport Astralane tip. Bifrost does not add sub-threshold tips from different bundle members together.

POST /astrln-submit-bundle

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "sendBundle",
  "params": [
    ["<BASE64_SIGNED_TRANSACTION_1>", "<BASE64_SIGNED_TRANSACTION_2>"],
    { "encoding": "base64", "mevProtect": true, "revertProtection": false }
  ]
}

sendBatch

Up to 25 independent transactions; each returns its own signature. Every transaction must pay its own qualifying 10,000-lamport Astralane tip.

POST /astrln-submit-batch

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "sendBatch",
  "params": [
    ["<BASE64_SIGNED_TRANSACTION_1>", "<BASE64_SIGNED_TRANSACTION_2>"],
    { "mevProtect": true }
  ]
}

Response: {"jsonrpc":"2.0","id":1,"result":["<SIGNATURE_1>","<SIGNATURE_2>"]}.

sendIdeal

Exactly two transactions: one weighted toward priority fees, one toward tips. Both use the same durable nonce so the loser is cancelled once the other lands.

POST /astrln-submit-ideal

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "sendIdeal",
  "params": [["<BASE64_HIGH_TIP_LOW_FEE_TRANSACTION>", "<BASE64_LOW_TIP_HIGH_FEE_TRANSACTION>"]]
}

getNonce

Returns the managed nonce account an ideal pair needs.

GET  /astrln-get-nonce
POST /astrln-get-nonce

Response:

{ "nonce": "<HASH>", "nonceAccount": "<PUBKEY>", "nonceAuthority": "<PUBKEY>" }
