Polymarket Arb Scanner: every locked-payout arbitrage on Polymarket, checked every 10 minutes

BOTLAB scans every open Polymarket market (about 47,000) for arbitrage that should pay out no matter what happens: buying every outcome of an event for less than $1, YES plus NO below $1, and mispriced "above $X" ladders. Profit is computed after taker fees and order-book depth. A paper book enters each gap once and settles it from the real resolution, so traps (an unlisted "Other" outcome, rules that let every leg lose) are counted, not hidden. Paper only; no orders are sent.

HOW IT WORKS
YESBASKET buy YES on every outcome of a mutually exclusive event when the total < $1.
NOBASKET buy NO on every outcome when the total < n−1.
BINARY YES ask + NO ask < $1 in one market.
LADDER "above $X" ladders must be monotone: buy YES(lower) + NO(higher) when the pair costs < $1.
Paper book: each new opportunity is entered once (max $100) and settled from the real resolution. A TRAP is an "arbitrage" that paid less than promised — usually an unlisted "Other" outcome or rules that let every leg resolve NO. Events with placeholder outcomes are excluded. Read-only: no orders are sent.
