When the best wallets agree, you’ll know

Nostra flags a market when several high-score traders put real money on the same side within a day. It’s the one thing you can’t see by scrolling the leaderboard.

How a signal fires

3 or more top wallets

Traders scoring 80 or more, not random accounts.

Real money

At least $5K each, so a signal isn’t noise.

Same side, same day

All on the same outcome within 24 hours.

Checked every 6 hours

Across the top 100 trending markets, and again when you open one.

A score you can check

Every scored trader gets a number from 0 to 100, compared with Polymarket’s top traders and refreshed every week. It describes what they’ve done, not what they’ll do next.

No. Nostra shows you what traders do. You decide, and you place any trade yourself on Polymarket. Nostra never holds your money or trades for you.

No. You can follow any trader or group without linking anything. If you like, you can add your public Polymarket profile, but Nostra never asks for keys, passwords or funds.

Each leaderboard trader gets a score from 0 to 100 based on win rate, return, consistency and track record, compared with Polymarket’s top traders and refreshed every week. It describes what they’ve done, not what they’ll do next.

From data Polymarket makes public: leaderboards, wallets, trades and positions. Nostra works out scores, groups and smart money signals from it.

No. Nostra is independent and isn’t affiliated with, endorsed by or sponsored by Polymarket.
