One open toolkit, three ways in. Ship encrypted on-chain AI from five lines of code, carry it in a self-custodial wallet with AI chat built in, or turn a spare GPU into a worker earning LCAI. Independent and fully open source.
lightnode-sdk for encrypted on-chain AI. Plus bridge, DAO, model registry, worker watch. Non-custodial.
The LightNode Wallet: self-custodial keys, encrypted AI chat, DAO voting, swap and bridge. Your keys never leave your device.
One-click desktop app. Generates your worker keys, funds + stakes from your wallet, brings the node online. Earn LCAI per inference job.
Live from the LightChain mainnet worker subgraph, refreshing every 30s
Download the app, press Install, and it handles the rest - reads your hardware, sets up the node, stakes, and goes live. No terminal, no config, no copy-paste.
npm install lightnode-sdk viem gets you encrypted inference plus the whole ecosystem.
5-line API. Wallet signs, SDK encrypts + streams the answer.
searchEnabled routes to a search-capable worker; result carries cited sources.
History + system prompt. Reuses one session, one tx per turn.
Read workers, jobs, models, and stats. No key needed.
Move LCAI Ethereum <-> LightChain. Quote, approve, transfer.
Read + vote on both governors (Ethereum + LightChain).
One real test inference; event stream on state change.
Parallel inference with capped concurrency. Per-slot errors.
ReAct-style tool calling. Works on llama3-8b.
Got a spare GPU and 50,000 LCAI? The desktop app handles keys, staking, Docker, and the watchdog.
macOS, Windows, or Linux. No sign-up, no API key.
Auto-detects GPU/CPU/RAM and scores against the 8GB-VRAM floor.
Generates keys, funds and stakes from your wallet, starts the node. No terminal.
Track jobs, earnings, and health. Settle, withdraw, deregister - all in the app.
What the network pays workers to serve. Builders call these via the SDK; operators serve one or more.
Confirm your hardware clears the minimum spec, or matches the recommended spec for headroom, before you start onboarding.
Two tracks, one community. Most people only need one. Both are live on mainnet today.
