Solana Transaction Sending API
Send and Track
Use one hosted endpoint to send signed Solana transactions, then track lifecycle updates with SSE or status polling. A cleaner fit for bots, agents, and apps that do not want to stitch submission and tracking together by hand.

Typical Flow
1
Send any signed transaction
Use `/v1/send` when you already have a signed transaction and want one hosted submission surface instead of wiring your own send flow.
2
Track early lifecycle updates
Use `/v1/stream/tx` for realtime transaction lifecycle updates when your app or bot needs fast post-submit visibility.
3
Fall back to status polling
Use `/v1/tx/:signature` when SSE is unavailable or when you want a simple status check after submission.
