first_img Coinbase Wallet launches a loyalty program, offering up to 50% cashback on exchange fees

Coinbase self-custody wallet Coinbase Wallet has announced the launch of a loyalty program aimed at users who continuously engage in exchange transactions. Users can receive up to 50% of eligible exchange fees back in USDC each week. Trader levels are divided based on the eligible trading volume over the past 30 days: Explorer for under $5,000; Trencher for $5,000 and above, with a 15% rebate; Pro for $25,000 and above, with a 30% rebate; Legend for $100,000 and above, with a 40% rebate; VIP for $500,000 and above, with a 50% rebate.Rebates are calculated based on the actual exchange fees retained by Coinbase Wallet after discounts, excluding network fees and gas fees. Levels are updated daily, and higher rebate rates apply immediately upon reaching a higher tier; if trading volume decreases, levels can drop by one tier at most per week. Each wallet's trading volume is calculated separately and is not combined across wallets. Eligible rebates accumulate automatically and are paid weekly in USDC, without the need to enter codes or manually claim.New users who register through a friend referral link can receive a first exchange reward of up to $35 USDC on eligible exchanges and enjoy a 10% discount on eligible exchange fees, with related transactions counting towards level progress. Loyalty rebates are calculated after fee discounts. Users who share referral links can earn 25% of the net fees collected by Coinbase Wallet from their friends' eligible exchanges, paid in USDC. VIP users can also directly contact the product team, get early insights into upcoming features, and receive invitations to exclusive events. The program has regional and eligibility restrictions, and terms may be adjusted or terminated.

CryptoQuant: The supply and demand pattern of BTC is changing, but a strong recovery still faces challenges

CryptoQuant's latest analysis indicates that while Bitcoin has support, the recovery process is uneven. First, regarding exchange reserves, it has risen from about 2.67 million BTC at the beginning of October to about 2.68 million BTC, still far below January levels. Low reserves do not mean that supply is continuously shrinking; transfers may reflect custody changes, and the increase itself does not prove selling pressure. Secondly, the recovery of spot demand has been hindered, with 30-day spot demand once approaching zero before turning negative again. Perpetual contract demand is positive, supporting overall demand.Finally, the behavior of whales is diverging. Addresses holding 100 to 1,000 BTC have still net accumulated over the past 60 days, but this is below the peak at the end of September; the group holding 1,000 to 10,000 BTC has seen a net decrease approaching zero; and the group holding over 10,000 BTC is negative. Accumulation is not fully underway. CryptoQuant believes that conditions still exist to support Bitcoin's bottoming out. For a solid recovery to occur, sustained spot demand support is needed, buyers must be able to absorb the BTC flowing back to exchanges, and accumulation behavior should spread to more holding groups. Market expectations regarding the U.S. midterm elections and monetary policy must translate into actual buying behavior. The key is whether price increases can attract a growing and lasting group of buyers.

first_img The Zcash development team plans to allocate independent keys for each ZEC exchange to prevent quantum cracking

The Zakura team, which operates the Zcash network, released a technical article stating that they plan to allocate a unique viewing key for each ZEC exchange completed through NEAR Intents, in order to block future quantum computers from exploiting public refund addresses to piece together user payment histories. NEAR Intents supports cross-chain token exchanges, and when users exchange the privacy coin ZEC for USDC, the service will publish a Zcash address for the user on the NEAR public blockchain, which will be used to return any unused ZEC.The Zcash address contains a public key generated by the wallet's viewing key, which cannot be reverse-engineered by ordinary computers, but large quantum computers running Shor's algorithm could theoretically deduce the key from the address. Zcash wallets can generate multiple seemingly unrelated addresses, but they typically share the same viewing key. Once an attacker cracks it, they can associate all payments received by the account and read the amounts and notes. Zakura's solution allocates a unique viewing key for each exchange, while the spending key remains in the user's main account. Even if the future refund address is compromised, the attacker would only be able to see payments related to that specific exchange.This design also addresses a practical issue: wallets conducting hundreds of exchanges would generate hundreds of keys, requiring each key to scan the entire Zcash chain during backup recovery. Zakura's solution is a privately queryable database that uses private information retrieval technology, so when the wallet inquires about the refund destination, the database will not know the address being queried. Zakura claims that wallets built on its open-source library (including Vizor) will be able to add this feature in the coming weeks, and hardware wallets will follow after firmware support, ahead of the January quantum-resistant payment target set by Zcash developers this month.
