What This Does
- Sends transactions with low latency
- Tracks confirmation status in real time
- Automatically retries unconfirmed transactions
- Returns parsed transaction data and Raptor events
- Measures send → confirm latency
Send a Transaction
Send a signed Solana transaction.
Endpoint
POST /send-transaction
Request Body
{
"transaction": "base64-encoded-transaction"
}
{
"signature": "4vJ9JU1bJJE96FWSJKvHsmmFADCg4gpZQff4P3bkLKi",
"signature_base64": "RXNzaWduYXR1cmU=",
"success": true
}
- Returns immediately after accepting the transaction
- Sending and retrying happens in the background
- Transactions are retried for up to 30 seconds or until confirmed
Track a Transaction
Check the status of a transaction sent via /send-transaction.
Endpoints
GET /transaction/{signature}
The signature can be base58 or base64.
Response (example)
{

"status": "confirmed",
"slot": 250123456,
"sent_at": 1703123456789,
"confirmed_at": 1703123456795,
"latency_ms": 6,
"transaction": { ... },
"events": [ ... ]
}
Status Values
pending – sent but not confirmedconfirmed – finalized on-chainfailed – transaction errorexpired – not confirmed before timeout
Raptor Events
If the transaction interacts with the Raptor program, events are automatically parsed and returned.
Supported Events
SwapEventSwapCompleteEventPlaceOrderEventFillOrderEventCancelOrderEventUpdateOrderEvent
Event Format
{
"name": "SwapEvent",
"data": "base64-encoded-data",
"parsed": {

}
Examples
Send a Transaction
const response = await fetch('/send-transaction', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ transaction: signedTx })
});
const result = await response.json();
console.log(result.signature);
Poll for Confirmation
async function waitForConfirmation(signature) {
for (let i = 0; i < 30; i++) {
const res = await fetch(`/transaction/${signature}`);
const tx = await res.json();
if (tx.status === 'confirmed' || tx.status === 'failed') {
return tx;
}
await new Promise(r => setTimeout(r, 1000));
}
throw new Error('Timeout');
}
Read Swap Results
const tx = await fetch(`/transaction/${signature}`).then(r => r.json());
for (const event of tx.events ?? []) {
if (event.name === 'SwapEvent') {
console.log(event.parsed.amountIn, '→', event.parsed.amountOut);
}
}
