Weekly Project Updates: Base Breaks Away from the Optimism Superchain, Moonwell Hacked Due to AI-Generated Code Vulnerabilities, etc

Feb 22, 2026

1. Base Integrates Key Network Components Into In-House Unified Codebase link

According to Base’s engineering team blog, Base will integrate key components running the network into its own unified codebase. Node operators will need to follow Base’s release versions instead of directly following Optimism’s versions. In the coming months, Base will gradually decouple from the OP Stack while continuing to cooperate with Optimism as an OP Enterprise customer. The official stated that this move will increase the upgrade cycle from 3 times to 6 times per year, and advance the upgrade from Optimistic Proofs to TEE/ZK Proofs in subsequent hard forks, while maintaining Stage 1 Rollup status and adding independent signers to the Base Security Council. Base is the highest-revenue L2 on the OP Stack, which means it may no longer share sequencer revenue with Optimism following its independence.

2. Claude Opus 4.6 Written Vulnerable Code Leads to $1.78M Loss in Moonwell Hack link

Smart contract auditor pashov tweeted that Claude Opus 4.6 wrote vulnerable code, leading to a smart contract attack and a loss of approximately $1.78 million. The price of cbETH was incorrectly set at $1.12, while the actual price should have been around $2,200. The project’s pull request shows the code submission was co-authored by Claude, which may be the first Solidity code hack caused by “vibe-coding”. Yu Xian, founder of SlowMist, added that the incident occurred on DeFi lending protocol Moonwell and was a low-level error in which the oracle price-feeding formula was written incorrectly.

Moonwell stated in a post that a potential recovery plan for users affected by the cbETH Core Market incident on Base has been launched on the governance forum, including a path to integrate the Moonwell Apollo (MFAM) community into the Moonwell ecosystem (WELL). The proposal includes: immediate partial repayment from the Moonwell Apollo Treasury; continuous subsequent repayment through protocol revenue; and providing stkWELL compensation to MFAM holders and stakers at a 1:1.5 ratio (MFAM:stkWELL).

3. ether.fi Plans to Migrate Crypto Debit Card Cash to Optimism, Involving Over $160M TVL link

ether.fi announced plans to migrate its crypto debit card product Cash to Optimism’s OP Mainnet (Superchain ecosystem) in the coming months. The migration will involve over 70,000 active debit cards, more than 300,000 accounts, and a total value locked (TVL) of over $160 million, marking a long-term strategic cooperation between the two parties aimed at accelerating global on-chain payments. The official emphasized that user accounts and underlying assets will remain secure throughout the migration, and existing products and services will continue to operate as usual.

4. Jupiter DAO Launches Vote: May Cancel 2026 Jupuary Airdrop link

Jupiter DAO has launched a zero-emission vote on the JUP token, which will conclude on February 22. The vote will decide whether to cancel the 2026 Jupuary airdrop to achieve zero net emissions and ease token dilution pressure. Voting options: 1. Keep Jupuary: Launch the airdrop checker one week after voting, distribute 200 million JUP, and implement the remaining reward pool and Jupnet incentives as originally planned. 2. Cancel Jupuary: Postpone the airdrop, return the prepared 700 million JUP to the community multi-signature cold wallet, with the snapshot retained for the future; suspend team token emissions indefinitely, accelerate Mercurial vesting, and buy back part of the newly released JUP to absorb selling pressure.

5. xStocks Total Trading Volume Surpasses $25 Billion link

Payward, the parent company of Kraken and xStocks, disclosed that since its launch in June 2025, xStocks’ cumulative trading volume has exceeded $25 billion. Meanwhile, xStocks accounts for 7 out of the top 10 tokenized stocks by 24-hour trading volume. Additionally, xStocks has officially launched its Chinese-language X (formerly Twitter) account.

6. Uniswap Launches Proposal to Expand Protocol Fees link

Uniswap announced that a proposal to expand protocol fees has been launched. The update plans to enable fees for all remaining v3 pools on the mainnet and activate protocol fees for v2 and v3 on eight newly added chains.

7. Hyperliquid LTM Revenue Hits $832.9 Million link

Artemis CEO Jon Ma said Hyperliquid LTM revenue reached $832.9 million. Comparison with Robinhood and Coinbase: Hyperliquid: market cap $7 billion, LTM revenue $832.9 million, P/S 8.4x; Robinhood: market cap $67.5 billion, LTM revenue $4.5 billion, P/S 15.1x; Coinbase: market cap $44 billion, LTM revenue $6.9 billion, P/S 6.4x.

8. x402 Early Sellers See 55.7% First-Month Retention, New Sellers in Peak Period Have Near-Zero Next-Month Retention link

The one-month retention rate of early x402 sellers (September 2025) was 55.7%, and the five-month retention rate remained at approximately 10%. However, the retention rate of sellers who joined after x402 gained popularity (after October 2025) dropped to nearly 0 in the second month.

9. Multi-Chain Lending Protocol ZeroLend Announces Gradual Shutdown After Around Three Years of Operation link

Multi-chain lending protocol ZeroLend has announced it will gradually wind down operations after approximately three years of running, citing reasons including declining liquidity across multiple supported chains, discontinued oracle support, and the protocol’s long-standing inability to achieve sustainable revenue. The platform has set most markets to 0% LTV and is urging users to withdraw their assets as soon as possible; locked funds on some chains will be returned via timelock upgrades and contract adjustments. LBTC users on Base will receive partial refunds.

10. DeFi Protocol Polynomial Ceases Operations and Shuts Down Chain and Trading Products link

DeFi derivatives protocol Polynomial announced in a post that it has ceased operations and entered the winding-down phase as of February 14 Beijing Time. It will shut down both Polynomial Chain and Polynomial Trade, conduct forced liquidations on February 18, close the liquidity layer on February 24, and halt chain operations on March 3. Polynomial also announced the cancellation of its previously planned TGE for the first quarter of 2026, stating it is unwilling to “issue tokens for a dying product”. The team said it will retain participant data and grant early supporters priority access to subsequent products of the new company.
