How Trade-Up Contracts Work

  • Trade 10 skins of the same quality to receive 1 skin of the next tier
  • All skins must be either Normal OR StatTrak (no mixing)
  • Souvenir skins cannot be used
  • The output skin comes from the same case/collection as one of your inputs
  • Each input skin adds probability weight toward its case's outcomes
