Uniswap token holders will begin voting on a significant proposal this Thursday to activate the protocol fee switch for two versions of the protocol on eight Layer 2 blockchains, including Base, Arbitrum, and OP Mainnet. Once activated, at least one-sixth of the fees collected from liquidity providers on the relevant chains will be transferred to the token pool for investors who burn an equivalent amount of UNI tokens, which is expected to more than double existing yields.The fee switch has been live on the Ethereum mainnet v2 and some v3 liquidity pools since December last year, generating a total of $3.3 million in revenue to date. Since 2026, Base has surpassed Ethereum to become the largest source of fees for Uniswap, generating $55 million in fees.Boosted by the proposal news, UNI has risen 9% in the past seven days, outperforming the declining Bitcoin and Ethereum during the same period. The final vote will conclude on March 4.

The South Korean cryptocurrency exchange Bithumb has continued to face pressure on its market share following the "Bitcoin Misissue Incident." Data shows that as of last Friday, Bithumb's trading share among the five Korean won-denominated exchanges in South Korea has dropped to 24.8%, a significant decline from about 30% at the beginning of the year. Industry data indicates that Upbit remains in the lead with a 58.4% share, followed by Coinone at 13%, Korbit at 3.5%, and Gopax at 0.3%.On February 6, Bithumb mistakenly issued 2,000 bitcoins, worth 2,000 won (approximately $1.38), to some users during a promotional event, totaling an erroneous issuance of about 620,000 BTC, far exceeding its previously disclosed holding of 42,800 coins, raising doubts about its internal controls and financial management capabilities.The day after the incident, its market share fell from 31.5% on January 5 to just over 20%. To stabilize the situation, Bithumb implemented a week-long zero-fee promotion for all cryptocurrencies starting February 9, which temporarily boosted trading volume, and on February 10, the market share briefly rebounded to 31.5%. However, following the end of the promotion on February 16, the share quickly declined again.Meanwhile, competitors have clearly benefited. Coinone's share has doubled compared to a month ago, and Korbit's trading volume has increased by about 12.5 times, driven by expectations surrounding Mirae Asset Financial Group's acquisition of a 92% stake. Upbit is advancing a comprehensive share exchange plan with Naver Financial, while Gopax has been acquired by Binance, potentially reshaping the landscape of South Korean exchanges.

Ethereum co-founder Vitalik Buterin responded to Sigil on the X platform, stating that extending the feedback distance between humans and artificial intelligence is not a good thing. This trend often leads to AI generating low-quality content rather than truly solving real human problems, and it has not achieved good optimization even at the level of entertainment experience.Vitalik further warned that once AI develops to a sufficiently powerful and potentially dangerous stage, such developmental paths could maximize the risk of irreversible anti-human outcomes, even leading the promoters themselves to feel regret. The goal of Ethereum is to grant freedom to humanity, not to create a self-operating system that leaves human conditions unchanged or even worsened.Additionally, Vitalik Buterin pointed out that current mainstream models operate on centralized infrastructure such as OpenAI and Anthropic, which is not true self-sovereignty. This disregard for centralized trust assumptions is contrary to the principles that Ethereum opposes.The trend of exponential technological growth itself is difficult to stop; therefore, the core task of the current era is not to further accelerate exponential expansion, but to guide its direction of development, avoiding the system sliding into uncontrollable or undesirable attractor states.ChainCatcher previously reported that X user @0xSigil announced on the X platform the construction of an AI system capable of autonomously generating income, self-improvement, and replication without human intervention. This technology aims to provide AI with "write" permissions to the world and supports a "new network" composed of exponentially growing sovereign AIs.The author introduced the concept of "WEB 4.0" in related discussions, defining it as the stage of the birth of superintelligent life. This system demonstrates the technological path for AI to achieve self-sustainability and evolution.Moreover, both Solana and Ethereum have retweeted this post, stating that the technology is closely related to the project.

According to The Block, Uniswap is voting on a proposal to enable protocol fees in all remaining v3 pools and to extend the fees to include eight new chains: Arbitrum, Base, Celo, OP Mainnet, Soneium, X Layer, Worldchain, and Zora.The proposal will use a newly created tier-based fee adapter that automatically applies protocol fees to all v3 pools based on the fee tier of liquidity providers.

Aptos announced an update to the APT token economic model, shifting to a performance-driven token supply mechanism that links APT supply to the actual usage of the network. Specifically, this update includes the following seven items:Reduce staking reward rate and incentivize long-term stakers. The Aptos Foundation has proposed to lower the annual staking reward rate from 5.19% to 2.6%. Additionally, the Aptos Foundation is exploring a governance proposal to change the staking framework to better align incentives with long-term network participation.Increase Gas fees by 10 times. Aptos is currently one of the lowest-cost blockchains, and given the current transaction fees are so low, the Aptos Foundation will propose to increase Gas fees to 10 times the current amount through governance proposals. After the increase, the transfer fees for stablecoins on the network will still be as low as approximately $0.00014.Transaction utilization and fees. A new deflationary mechanism will be introduced through the decentralized exchange protocol Decibel on the Aptos chain, where high-frequency trading activities will significantly consume and destroy APT. Currently, all forms of transactions paid in APT on the network, or "gas fees," will be permanently destroyed. Decibel, incubated in collaboration with Aptos Labs and the Decibel Foundation, represents one of the first fully decentralized exchanges where all trading activities are executed on-chain: every order, match, and cancellation is executed on-chain. With 100% on-chain execution, the launch of Decibel's mainnet will greatly enhance the transaction throughput of the Aptos blockchain.Hard supply cap fixed at 2.1 billion APT. Once approved by the community, no new tokens will be minted beyond this cap.Foundation permanently locks 210 million APT. The Aptos Foundation will ensure that 210 million APT are locked and permanently staked in the network. These tokens will never be sold or distributed and will be permanently locked.Performance-linked grant issuance. In the future, the Aptos Foundation will primarily focus on providing future grants and rewards that will only be redeemed upon achieving key milestones related to Aptos's role as a "global transaction engine."Launch a programmatic buyback plan. The Aptos Foundation has committed to exploring a protocol buyback plan or reserve that will programmatically buy back APT on the open market based on market opportunities.

According to the official announcement from Pump.fun, the platform has launched a new feature called Cashback Coins, allowing token creators to choose to return all Creator Fees to traders before issuance, rather than to the token deployers. Pump.fun stated that while Creator Fees play a positive role in helping teams, creators, and founders grow and succeed, many tokens have succeeded without a team or project leader, which has led to disproportionate rewards for token deployers who should not receive fees. Unlike tokens that charge Creator Fees, Cashback Coins cannot undergo CTO (Creator Token Offering). Users can claim cash back rewards through the "Rewards" section of the Pump.fun mobile app. Once the token is issued, this decision will be permanently locked.

The founder of Bitcoin Strategy, Michael Saylor, posted on the X platform stating that during bank holidays, Bitcoin can still transfer any amount to any location in the world within minutes, with transaction fees of about $0.44 (approximately 1 sat/vB).During the previous "Blocksize Wars" period, there were widespread concerns in the market that Bitcoin would face a scalability crisis. However, more than a decade later, Bitcoin's on-chain transaction fees remain low, and network bandwidth resources are abundant. This outcome once again demonstrates that market mechanisms and technological innovations are often more effective in addressing systemic challenges than administrative emergency interventions.

Polymarket official Rodrigo posted on Discord that the fee mechanism will be expanded to the NCAA and Serie A markets. The fee structure is the same as the "15-minute cryptocurrency rise and fall market," meaning the taker pays the fee while the maker receives a rebate, but the coefficients are different ------ the rate is 0.0175, the index is 1, and the maker rebate is 25%, so the overall cost will be lower.Starting from 00:00 UTC on February 18, 2026 (Wednesday), all new NCAAB and Serie A related events created after this time will be subject to the new fee mechanism, while existing events will not be affected. The first rebate distribution will occur at 00:00 UTC on February 19.
