ChainCatcher tin tức, theo báo cáo của Crypto Briefing, Công ty lưu ký và thanh toán của Mỹ (DTCC) đã thêm ETF Staking Polkadot của 21Shares vào danh sách niêm yết của mình, mã là TDOT, đánh dấu sản phẩm này chính thức gia nhập hệ sinh thái ETF của Mỹ. Trong khi đó, 21Shares đã đổi tên quỹ từ "21Shares Polkadot ETF" thành "21Shares Polkadot Staking ETF", sự thay đổi này có hiệu lực từ ngày 27 tháng 8 năm 2026.Sự thay đổi tên này không chỉ là điều chỉnh bề mặt, "Staking" đã truyền đạt rõ ràng cơ chế sản phẩm đến các nhà đầu tư tổ chức: quỹ này nắm giữ token DOT, sẽ staking từ 40% đến 95% số lượng nắm giữ thông qua các xác thực viên mạng, và phân phối lợi nhuận cho cổ đông theo quý. Hiện tại, tỷ lệ lợi nhuận staking là 2.04%, phí quản lý là 0.3%, việc lưu ký được thực hiện bởi Anchorage Digital, BitGo và Coinbase. ETF này đã niêm yết trên Nasdaq vào ngày 6 tháng 3 năm 2026, với vốn khởi đầu khoảng 11 triệu USD, tính đến cuối tháng 8, quy mô tài sản quản lý khoảng 7.5-7.9 triệu USD.

ChainCatcher thông báo, theo Protos, tài liệu tiết lộ mới nhất của quỹ ETF Polkadot (TDOT) thuộc 21Shares cho thấy, quỹ này đã ghi nhận khoảng 4.52 đô la lỗ thực hiện cho mỗi 1 đô la lợi nhuận phân phối khi thanh toán lợi nhuận staking thông qua việc bán token DOT trong quý 2 năm 2026.Theo tài liệu quản lý, TDOT đã bán 98,505 token DOT trong quý 2, thu về khoảng 107,500 đô la tiền mặt để thanh toán lợi nhuận staking cho cổ đông. Tuy nhiên, do giá DOT giảm mạnh, các hành động bán này đã xác nhận khoảng 485,600 đô la lỗ.Dữ liệu cho thấy, giá DOT đã giảm khoảng 34% trong quý 2 năm 2026, với mức giảm tích lũy đạt 76% trong 12 tháng tính đến ngày 30 tháng 6. Do cổ đông TDOT nhận được phân phối tính bằng đô la, thay vì trực tiếp nhận phần thưởng staking DOT, quỹ cần bán DOT để chuyển đổi thành tiền mặt, từ đó khóa lỗ trong môi trường giá thấp. Trong quý 2, TDOT đã thanh toán tổng cộng khoảng 0.14698 đô la/cổ phiếu lợi nhuận cho cổ đông, nhưng trong cùng thời gian, giá cổ phiếu quỹ đã giảm từ 14.95 đô la xuống 9.86 đô la, với mức giảm khoảng 34%, lợi nhuận staking không bù đắp được tổn thất do giá tài sản giảm.

Theo thông tin từ ChainCatcher, theo báo cáo của Cointelegraph, Polkadot OpenGov gần đây đã đề xuất hai đề xuất mới về việc staking (đề xuất #1909 và #1910), nhằm tăng cường động lực cho các validator, loại bỏ cơ chế phạt cho các nominator, và rút ngắn thời gian khóa từ khoảng 28 ngày xuống còn 2 ngày.

Polkadot posted on X that OpenGov is voting on significant changes to the network staking architecture. Referendum 1890 proposes that validators on Polkadot must lock at least 10,000 DOT as self-staking.This reform is a mandatory prerequisite for the next phase of staking upgrades, which include immunity from slashing for nominators and quick unbonding (approximately 24-48 hours instead of 28 days). The logic is to allow validators to absorb slashing risks directly through significant self-staking exposure, while nominators can continue to earn staking rewards without exposing their principal. If passed, Polkadot staking will eliminate two major barriers to participation, thereby reducing the risk for nominators and shortening exit times.

According to on-chain analysis platform Arkham (@arkham), attackers exploiting the Bridged Polkadot vulnerability have transferred all stolen funds into Tornado Cash, involving an amount of approximately $269,000.

Polkadot stated on the X platform that the team has noticed security issues with the Ethereum gateway contract of Hyperbridge. This vulnerability only affects DOT tokens bridged to Ethereum via Hyperbridge, while DOT within the Polkadot ecosystem and other bridging solutions are not affected. Polkadot and its parachains and native DOT remain secure. Hyperbridge has suspended operations during the investigation.According to previous news from ChainCatcher, the Hyperbridge contract encountered an MMR proof replay vulnerability, resulting in a loss of approximately $242,000.

Due to the detection of a security incident involving Polkadot, Upbit has immediately suspended the deposit and withdrawal services for Polkadot (DOT) and its AssetHub Polkadot network.Upbit will collaborate with the project team to ensure asset security and will notify users of the resumption time once the stability of deposits and withdrawals is confirmed. During the service suspension, the deposit refund and withdrawal address registration processes will also be paused.

According to monitoring by Pidun, 1 billion DOT tokens were abnormally minted and sold on the Ethereum chain.On-chain data shows that about 1 hour ago, the attacker transferred the contract control to a malicious address by tampering with administrator permissions, subsequently minting 1 billion DOT and immediately selling them, causing the coin price to plummet from $1.22 to nearly zero.The incident is still unfolding, and Polkadot's official response has not yet been released. The target of this attack was bridging assets on Ethereum, not the native Polkadot chain.

Polkadot announced on platform X that its token issuance model upgrade has officially taken effect. This protocol update will introduce several key adjustments, including setting the maximum supply of the native token DOT to 2.1 billion tokens, with approximately 80% of the tokens already issued. At the same time, the issuance rate of DOT will be reduced by about 53% in one go, with plans to continue gradually lowering it in the future.It is reported that the above adjustments were proposed by the community and approved through the OpenGov governance mechanism, aiming to maintain the network's incentive mechanism while limiting the long-term issuance scale and providing the market with a more transparent and predictable token issuance path.

Polkadot will implement several changes starting from March 12, 2026, including a new DOT issuance model, the introduction of a Dynamic Allocation Pool (DAP), and adjustments to staking, budget allocation, and network security mechanisms.The proposal sets the total supply cap of DOT at 2.1 billion; it introduces a Dynamic Allocation Pool (DAP) to replace the original treasury destruction mechanism, depositing transaction fees, Coretime sales revenue, and slashing funds into a permanent account for dynamic budget allocation; 13.14% of the remaining supply will be issued every two years, with the initial issuance amount reduced by 53.6% compared to the current model.In addition, the staking mechanism will also undergo significant updates: starting from mid to late March, validators will need to hold at least 10,000 DOT in a slashing-capable self-stake and set a minimum commission rate of 10%; from April, nominators will become non-slashable, and the unbonding period will be significantly shortened from 28 days to 24 to 48 hours.

Web3 Foundation announced that it will gradually end the official customer support operations for Polkadot. The official statement indicates that as the Polkadot ecosystem continues to mature, its strategic focus will shift from expanding centralized support functions to prioritizing the development of more intuitive and autonomous products and user interfaces, thereby reducing users' reliance on customer support from a system design perspective.According to the subsequent arrangements, the official support contact form will remain open for one week after this announcement is made, and will then officially close, but any remaining submitted tickets will still be processed; the AI chatbot will also be taken offline. Additionally, the existing support page knowledge base will be temporarily retained, but no further content updates or maintenance will be conducted. In the future, user help and support will be fully transitioned to a decentralized community, and the official recommends that users seek assistance through Polkadot community channels such as Discord, Reddit, and Telegram.
