CS2 opens Trade Up Contracts to Souvenir skins

Counter-Strike 2 began accepting Souvenir-quality items in Trade Up Contracts on May 21, 2026. Valve’s update gives eligible Souvenir skins a new use, but the output does not retain their Souvenir identity.

Ten qualifying items are still required. The contract returns one normal item of the next-highest rarity from one of the collections represented by the submitted skins.

Souvenir attributes are removed on submission

Valve states that Souvenir attributes are stripped from items used in a contract. That distinction is essential: tournament stickers, event provenance and the Souvenir label are part of the input’s collectible character, but they do not transfer to the result.

A contract should therefore be treated as an irreversible conversion, not an upgrade that preserves memorabilia. Players should inspect every selected item and avoid submitting a skin whose sticker combination or match association has personal or market value.

Collection odds still matter

The possible output collections are determined by the items placed in the contract. Mixing collections broadens the result pool, while float values continue to matter for the wear of the resulting normal skin. The update creates an additional supply route; it does not guarantee profit.

Our CS2 community-map update report covers another part of Valve’s recent live-service work, while the Ancient utility guide stays focused on competitive play.

Before confirming any contract, compare the input cost with every possible output and verify current market prices independently. Valve’s official announcement archive documents the rule change.

The contract preview should always be reviewed before submission.
