Running a keeper league shouldn't be a second job.
Who kept whom, and for how long?
Years kept live in a spreadsheet only you understand — and one wrong cell means an argument.
Traded picks with nowhere to live
Picks traded for future seasons have to be tracked somewhere outside Yahoo, by hand.
The keeper deadline scramble
Chasing managers for their keepers, checking who's eligible and what each one costs.
Running a redraft league and want to add keepers? IceVault sets up the rules for your first keeper season too.
What you get
Keeper selection, with your rules enforced
Managers pick and lock their keepers in IceVault before your deadline. Year limits are enforced, keeper costs follow your model (no cost, reserved rounds, or rounds you assign), and you can override any selection.

Years kept, across seasons
Every keeper's years kept carries forward each season, even when Yahoo gives your league a new key for the new season.

Every draft pick, including Yahoo trades
Each team's picks for the next three seasons on one board. Picks traded inside Yahoo trades are brought in automatically, and anything that doesn't line up is held for you to review. Before the draft, a cheat sheet lists the keepers and traded slots to set up on Yahoo.

Trade Center for players and picks
Managers propose trades with players and future picks. Choose commissioner approval or a league veto vote, set a trade deadline, and managers get email updates as a trade moves along.

Weekly category contest and payouts
Feature one Yahoo stat category each week; winners come straight from Yahoo's scoreboard. Track weekly prizes, entry fees and season payouts in one place.
Daily Yahoo sync and season rollover
Rosters and standings refresh from Yahoo every morning during the season. When your league renews on Yahoo, IceVault links the new season and carries keepers, picks and history forward.
