MetaMask & Linea Partner with Brevis to Roll Out ZK-Proof Rewards—Exclusive Perk for MetaMask Cardholders

Zero-knowledge proofs meet everyday spending as MetaMask teams up with Linea and Brevis to turbocharge its card rewards program.

Here's the deal: Holders of the MetaMask Card—the slickest crypto debit tool this side of Web3—now get ZK-backed rewards. No gimmicks, just cryptographic proof that your loyalty pays (literally).

Why it matters: While traditional banks slap on 0.1% cashback like it's 1999, Web3 wallets keep innovating. Linea's zkEVM tech and Brevis' proof aggregation create a rewards system so seamless, even your grandma could audit the transparency. Take that, legacy finance.

The fine print: Exact reward structures still under wraps, but expect tiered perks based on transaction volume. Because in crypto, whales always get VIP treatment—some decentralization, huh?

Bottom line: Another step toward mainstreaming crypto utility... or just a clever ploy to get you to swipe more? Either way, the ZK-rewards arms race is on.

A blueprint for transparent web3 incentives

According to the announcement, the campaign addresses long-standing issues in web3 incentives, such as opaque tracking and high participation barriers. By integrating ZK proofs, the rewards process becomes fully trustless and transparent.

Every four hours, Brevis computes the time-weighted average of a user’s collateral and debt, produces a proof of eligibility and reward calculation, and submits it to Linea’s smart contract for on-chain verification. Linea and MetaMask have framed the campaign as more than a promotional effort, calling it a model for permissionless, verifiable incentive systems.

In addition to boosted yields, MetaMask Card users can earn between 1% and 3% cashback in USDC on purchases, plus up to 10% back in “Coinmunity” rewards, tokens, NFTs, or other digital assets issued directly by participating brands on Linea.

Community speculation regarding Metamask stablecoin

The campaign arrives amid speculation over MetaMask’s potential product roadmap. While unconfirmed, industry chatter points to the possible launch of a MetaMask-branded stablecoin, mUSD or mmUSD, later this month. A separate native token, MASK, has been rumored for years, though MetaMask’s parent company, ConsenSys, maintains that no such token exists at present.

For now, the focus is on using layer-2 scalability and ZK proofs to make on-chain rewards as seamless as traditional finance perks, while preserving the transparency and composability of DeFi.
