What Tessera does
Three things, done precisely.
Settlement-fingerprint review
We compare each venue's resolution rules. Only markets that settle on identical terms — and survive real fees — are shown as signals.
Non-custodial by design
Trade Polymarket directly from your own wallet. Tessera never touches your funds or your private keys.
Why it's different
A spread is not an edge.
Most tools flash you a price gap and let you assume it's free money. A gap between mismatched rules — after fees — is often a loss. Tessera filters those out.
Naive spread tool
Shows the gap. Hides the catch.
A 6¢ spread looks like easy profit — until the venues settle on different terms and fees eat the rest.

False arbitrage — you can lose on both legs
Tessera verified signal
Shows only what survives.
Same market, after fingerprint review and real fee deduction. If the edge doesn't survive, it never reaches you.
