Marvel Contest of Champions hands out promo codes for crystals, revives, energy refills, gold, and the occasional free champion. These codes only stay active for a short window, so redeeming them quickly matters.

Here is every code currently confirmed to work, along with the rewards each one unlocks.

How to redeem MCOC codes
Codes are entered through the game’s Summoner’s Market website, not the app itself. You need a Kabam account linked to your in-game profile before a code will register.
A successful redemption shows a confirmation message on the shop page, and the reward appears in your in-game mailbox the next time you open the app. Codes are case-sensitive in most cases, so match capitalization exactly as listed above.
Claiming daily and weekly shop rewards
The Shop page also offers free gold and crystals on a daily and weekly cycle, separate from the promo code box. Log in regularly to collect these on top of any active codes, since they add up over a season.
Expired MCOC codes
These codes no longer register on the redemption page.

New codes tend to surface around livestreams, in-game events, and character launches like Symbiote Spider-Man’s arrival. Check the Shop page’s Promo Codes box periodically, since most codes only stay valid for about 24 hours once released.
