About this extension

Tradyr puts dynasty fantasy football values everywhere you already research players — no more flipping between tabs.

A small, colour-coded badge appears next to player names showing the Tradyr Composite: a blended score from KeepTradeCut and FantasyCalc that gives you one number to trust at a glance. Click any badge to open the full player profile on tradyr.app — historical value chart, rest-of-season projection, advanced stats and metrics.

WHERE IT WORKS
• Sleeper — rosters, trade builder, league pages (with a live trade-totals overlay that scores both sides as you build)
• KeepTradeCut — rankings, player pages, trade calculator
• FantasyCalc — rankings and trade tool
• FantasyPros, Yahoo Fantasy, ESPN Fantasy, MyFantasyLeague, Fleaflicker
• X / Twitter — adds a value row under any tweet that mentions players
• News & analysis: NFL.com, DynastyLeagueFootball, PFF, RotoWire, RotoBaller, NumberFire, CBS Sports, Yahoo Sports, The Fantasy Footballers, Draft Sharks, Pro Football Reference, NBC Sports, The Athletic, Reddit, ESPN.com

WHAT IT SHOWS
• Composite value (KTC + FantasyCalc, position-normalised)
• Position pill (QB / RB / WR / TE / Pick) with consistent colours
• Confidence score and overall rank on hover
• Bye week beside each badge during the season
• Live trade totals on Sleeper trade pages, sums each side, shows the delta, calls out the winner
