Connect Lighter in TensorTrader

Your seed phrase and main private key never leave your wallet. TensorTrader stores your public address and the restricted agent key, encrypted. That is the security baseline for every DEX that supports delegated keys.

1. 1Sign in and open Settings (the tab on the right edge), then the Exchange Auth tab.
2. 2Pick Lighter. Instead of key fields you get a connect wizard.
3. 3Connect your browser wallet and choose the test network first.
4. 4Approve the trading agent with one wallet signature. The agent can place and close trades; it cannot withdraw.
5. 5Wait for the green status and the balance to appear. If both networks read empty, fund the test account first.

Your first Lighter order from the Chrome extension

Orders reach Lighter through TradingView alerts. The TensorTrader extension builds those alerts for you: open TradingView, open the extension side panel, and use the Batch Create tab. Pick this Lighter key in step 1 · Exchanges, type your tokens, choose an indicator or strategy from your TradingView favorites, review the plan and press Create.

When an alert fires, TensorTrader sizes the order, clamps leverage to the lower of your policy and the venue maximum, places it on your key and shows the fill on your dashboard.

Beta Pioneer: 90 days, plus seats to share

A verified trade-only Lighter key makes you a Beta Pioneer: your free beta runs 90 days instead of 30, and you get an invite code with 90-day seats for other traders. The code has 5 seats while we are still finishing a venue, and 2 once it is complete.

Find the code under Settings → Community and use "Copy invite link". Each seat gives a new account the same 90-day beta.
