According to Crypto Briefing, the U.S. Depository Trust & Clearing Corporation (DTCC) has added 21Shares' Polkadot Staking ETF to its listing, with the code TDOT, marking the official entry of this product into the U.S. ETF ecosystem. Meanwhile, 21Shares has renamed the fund from its original name "21Shares Polkadot ETF" to "21Shares Polkadot Staking ETF," with this change taking effect on August 27, 2026.This name change is not just a superficial adjustment; the term "Staking" clearly communicates the product mechanism to institutional investors: the fund holds DOT tokens, stakes 40% to 95% of its holdings through network validators, and distributes earnings to shareholders on a quarterly basis. The current staking yield is 2.04%, with a management fee of 0.3%, and custody is jointly handled by Anchorage Digital, BitGo, and Coinbase. The ETF was listed on Nasdaq on March 6, 2026, with initial seed funding of approximately $11 million, and as of the end of August, the assets under management are approximately $7.5 to $7.9 million.

According to Protos, the latest disclosure from 21Shares' Polkadot ETF (TDOT) shows that in the second quarter of 2026, for every $1 in distribution income generated through the sale of DOT tokens to pay staking rewards, there was an accompanying realized loss of approximately $4.52.According to regulatory documents, TDOT sold 98,505 DOT in the second quarter, generating about $107,500 in cash to pay staking rewards to shareholders. However, due to a significant drop in DOT prices, these sales confirmed a loss of approximately $485,600.Data shows that DOT fell by about 34% in the second quarter of 2026, with a cumulative decline of 76% over the past 12 months as of June 30. Since TDOT shareholders receive distributions in USD rather than directly receiving DOT staking rewards, the fund needs to sell DOT to convert to cash payments, thereby locking in losses in a low-price environment. In the second quarter, TDOT paid shareholders a cumulative distribution of approximately $0.14698 per share, but during the same period, the fund's share price dropped from $14.95 to $9.86, a decline of about 34%, and the staking rewards did not offset the losses caused by the decline in asset prices.

According to Cointelegraph, Polkadot OpenGov recently proposed two new staking proposals (Proposal #1909 and #1910) aimed at strengthening validator incentives, eliminating the nominator penalty mechanism, and reducing the unbonding period from approximately 28 days to 2 days.

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.
