sendBundle

Last updated:

sendBundle submits an ordered bundle of fully-signed Solana transactions to be executed back-to-back, atomically, within a single block. Either every transaction in the bundle lands in the given order, or none of them do — there is no partial execution. This is the submission counterpart to simulateBundle, which dry-runs the same bundle without broadcasting it.

Because the bundle lands atomically and in order, later transactions can safely depend on the state changes produced by earlier ones (for example, a swap that funds a later repay). Use it for MEV / atomic-arbitrage strategies and any sequence of dependent transactions that must not be interleaved with other traffic.

This is a pro-tier-only method, rate-limited separately under the sol_send_bundle category at 10 RPS (pro) / 30 RPS (business), with burst headroom of twice the sustained limit. Always simulateBundle first: a bundle that would revert is rejected at submission, and you still consume your send budget.

Examples

curl https://triport.io/sol \
  -X POST -H 'Content-Type: application/json' \
  -H 'Authorization: Bearer <api-key>' \
  -d '{"id":1,"method":"sendBundle","params":[],"jsonrpc":"2.0"}'
const res = await fetch("https://triport.io/sol", {
  method: "POST",
  headers: { "Content-Type": "application/json", Authorization: "Bearer <api-key>" },
  body: JSON.stringify({
  "id": 1,
  "method": "sendBundle",
  "params": [],
  "jsonrpc": "2.0"
}),
});
const data = await res.json();
import requests
resp = requests.post(
    "https://triport.io/sol",
    headers={"Authorization": "Bearer <api-key>"},
    json={"id":1,"method":"sendBundle","params":[],"jsonrpc":"2.0"},
)
print(resp.json())
