Web3 data provider Covalent has partnered with Wallchain to launch the “Covalent Mindshare Leaderboard,” a campaign that will distribute $200,000 worth of CXT tokens over the next five months. Rewards will be paid monthly, and participants’ rankings are determined by the quality and signal of the content they generate. Covalent says its platform handles about 2 million API calls each day from clients including OpenSea, Wormhole and Consensys. The rollout comes as other SocialFi projects step up user-engagement incentives. Social platform KaitoAI on Monday integrated the Moonbirds NFT collection into its leaderboard and introduced optional wallet verification that gives verified holders a ranking boost, marking the system’s first use of on-chain ownership data. In a related push, LetsCatapult told users that $19,000 in USDT prizes remain available during the final four days of its own mindshare-mining programme, underscoring intensifying competition among Web3 projects to convert social activity into measurable token rewards.
