Question 1

What is Polymarket copy-trading?

Accepted Answer

Polymarket is a prediction market that settles on-chain, so every trader's positions are public. Copy-trading means mirroring the bets of consistently profitable traders. REX only copies proven resolvers — people who win by holding to the final result, not by flipping early — and proves the edge out-of-sample before surfacing a single pick.

Question 2

What is a survivorship-bias-free backtest?

Accepted Answer

Tape-only reconstructions can't see losses — a losing position leaves no redemption event, so it silently disappears and hit-rates inflate. REX reconciles against ground-truth on-chain resolutions so losers stay counted, and measures skill out-of-sample so nothing is fit with hindsight.

Question 3

Does REX touch my funds?

Accepted Answer

No. REX is a read-only research engine. It surfaces who to copy from real on-chain data; you place every bet yourself on Polymarket. It never sees your keys and never moves your funds.
