Example with SolanaMevBot specific endpoint, you need to tip at least 7500 and use no_failure_mode = true to use this endpoint:

[[sending_venders.sending_vender]]
enabled = true
tip_amount = { strategy = "Random", from = 7_500, to = 7_500, count = 1 }
compute_unit_price = { strategy = "Random", from = 1031, to = 2055, count = 1 }
urls = [
    "https://fast.circular.fi/transactions/no-failure/smb",
]
auth_header = "x-api-key"
auth_value = "xxx"
tip_accounts = [
  "FAST3dMFZvESiEipBvLSiXq3QCV51o3xuoHScqRU6cB6",

]
no_failure_mode = true
sending_strategy = "AllAtOnce"  # AllAtOnce or OneByOne

Example with general endpoint:

[[sending_venders.sending_vender]]

tip_amount = { strategy = "Random", from = 1_000_000, to = 1_000_000, count = 1 }

]
no_failure_mode = false
sending_strategy = "AllAtOnce"  # AllAtOnce or OneByOne

Bot provides a default key for astralane with a shared rate limit, and only usable with no_failure_mode = true. If you want to use your own key you can append it at the end of the url with api-key= and it will override the default key.

Atomic `sendBundle` example

Use this separate configuration when you want Astralane to submit the bot's transactions as one ordered, atomic bundle. Astralane accepts at most four transactions per bundle, so max_transactions_per_request = 4 makes the bot reject a larger bundle instead of splitting it and losing atomicity. See Astralane's sendBundle documentation for the request and protection options.

This example uses your own Astralane API key in the recommended api_key header. You can instead put it in the URL as ?api-key=YOUR_ASTRALANE_API_KEY. Choose either the existing example above or this bundle example unless you intentionally want to submit through both paths.

Notes

Minimum tip: 0.001 SOL (1_000_000 lamports). Transactions tipping below this are rejected.
API key is passed as the ?api-key= query parameter only. Header-based auth and the /api/v1/:key path are not supported.
Endpoint accepts POST with a JSON-RPC sendTransaction body (base64 tx in the transaction field).
QUIC submission is also available on port 8888 (ALPN lucum-tpu, API key in the TLS client cert CN) for lowest latency.
