Fidelity Investments announced plans to launch the Fidelity Digital Dollar (FIDD), its own U.S. dollar–pegged stablecoin. FIDD will be issued by Fidelity Digital Assets, National Association, and redeemable 1:1 for USD through Fidelity platforms. The product tagrets both retail and institutional investors. Fidelity will manage issuance, reserves, and daily transparency disclosures, with FIDD expected to launch on Ethereum mainnet in the coming weeks. The rollout comes as the stablecoin market reaches all-time highs above $300 billion and increased U.S. regulatory clarity for stablecoins with the GENIUS Act.

Robinhood CEO Vlad Tenev said the company plans to introduce instant settlement, 24/7 trading, and self-custody for its tokenized stocks. First launched in June 2025, Robinhood’s tokenized stocks are currently live on Arbitrum One, giving European customers access to more than 2,000 U.S. equities with 24/5 trading. Marking the five-year anniversary of the GameStop trading halt, Tenev said the episode reinforced his view that equity tokenization is the long-term solution to market disruptions. He argued that real-time, on-chain settlement can prevent the kind of trading restrictions seen in 2021. Robinhood ultimately plans to migrate its tokenized assets to Robinhood Chain, its own Layer 2 network.

The EF PSE team published a roadmap for enabling client-side zero-knowledge proof generation on everyday devices. The team says that modern consumer GPUs on phones and laptops are now powerful enough to accelerate core ZK primitives, making local proving practical. It notes that when proofs are generated on servers, the servers can see users’ private inputs. The proposed roadmap focuses on building ecosystem standards and reusable client-side GPU libraries, prioritizing post-quantum ZK systems, and developing best practices optimized for mobile devices. Client-side GPU acceleration could make Ethereum privacy fast, seamless, and resilient to future quantum threats.

Uniswap will add Continuous Clearing Auction (CCA) token launches directly in the Uniswap Web App. CCA is a permissionless auction protocol that helps teams distribute tokens and bootstrap liquidity on Uniswap v4. The auctions will appear in a new Auctions tab on the Explore page, going live on February 2nd, starting with Rainbow’s RNBW token launch.
