Tiny TypeScript demo of OrbitFlare's @orbitflare/sdk.

Subscribes to one Solana program over Jetstream, prints a live transactions-per-second meter and the last 10 signatures, redrawing every second. A WebSocket slotSubscribe() ticks the chain slot in the header so a quiet meter still shows a live network.

git clone https://github.com/orbitflare/jetstream-tx-rate.git
cd jetstream-tx-rate
npm install
export ORBITFLARE_LICENSE_KEY=ORBIT-XXXX-XXXX-XXXX
npm start pumpfun       # or: raydium, jupiter, or any raw program ID

Jetstream itself needs no api key, but the WebSocket slot feed picks one up from ORBITFLARE_LICENSE_KEY.

Override either endpoint with env vars:

JETSTREAM_URL=http://jp.jetstream.orbitflare.com \
ORBITFLARE_WS_URL=ws://fra.rpc.orbitflare.com \
  npm start raydium

Output:

jetstream tx rate: pumpfun (6EF8rrec...)
chain slot:        421442130

  last 1s:     14 tx/s
  last 10s:    9.7 tx/s avg

recent signatures:
   0.1s ago  slot 421442129  4bpPQBUHmobNJ4SS9ETLaMwY...
