UNPROTECTED
TRANSACTION LIFECYCLE

HOW IT WORKS

01

ENQUEUE

Pass Sinker a signed transaction. It accepts raw base64 over a single HTTP endpoint and takes it from there.

02

TIP ORACLE

The AI agent sizes the tip intelligently — informed by current network conditions and patterns built up from prior bundle outcomes — picking the amount most likely to land without overpaying.

03

BUNDLE

No polling. The sidecar watches the chain and the moment the first shred of a leader slot lands, the bundle is already in flight.

04

CONFIRM

Bundle status is tracked from submission through finalization. Events stream back to your app in real time via SSE.

Instantiate with your model provider and enqueue a pre-signed transaction. The agent picks it up automatically via SSE.

AI AGENT

The agent that drives tip selection and bundle timing is model-agnostic. Bring your own API key, pick your provider, or point it at a model running entirely on your machine. One environment variable is all it takes to swap the brain.
