Odaily reports: According to official disclosures from Acala, Polkadot parachain Acala and its Kusama sister network Karura have entered the shutdown phase. If Acala Referendum 195 and Karura Referendum 137 pass, both chains will cease block production on February 10, 2027. Users must withdraw cross-chain assets such as DOT, KSM, USDT, and USDC before that date; LDOT must be unbonded by January 12, 2027, and LKSM must be unbonded by February 2, 2027. The native tokens ACA and KAR cannot be withdrawn and will remain on the original chains. The team stated that DeFi liquidity depth in the Polkadot and Kusama ecosystems is insufficient, and the multi-parachain structure has also fragmented liquidity and users, leading to the decision to shut down.

According to monitoring by the Polkadot forum, a post-mortem of the XCM incident published on the forum shows that between October 24 and 26, a vulnerability in the XCM executor on Polkadot Asset Hub was exploited. The attacker reduced the bookkeeping issuance of dotUSD without changing account balances, distorting the pricing of the DOT/dotUSD pool and creating arbitrage opportunities, causing an estimated loss of approximately $1.381 million in DOT value. The Polkadot Treasury was the sole liquidity provider for the pool, and no user funds were lost. The post-mortem noted that the vulnerability had been reported in June through the bug bounty program, and the relevant code had been fixed, but the fix was not deployed in time to the affected mainnet runtime version. On October 20, the reporter publicly mentioned the fix on the forum, which may have provided clues to the attacker.

Odaily reports: The Polkadot Community Foundation has issued a security advisory stating that versions 3.0.1, 3.0.3, 3.0.4, and 3.0.5 of the third-party wallet Fearless's browser extension contain malicious code that may send private keys to attacker servers when users unlock their wallets. The relevant code was active during various periods between February 2025 and October 10, 2026.Currently, 8 users have reported unauthorized transactions potentially related to this vulnerability, involving 17,286 DOT.The Polkadot Foundation reminds users who have used the above extensions since February 2025 to treat all accounts within them as compromised, generate new keys using other wallets, and transfer assets as soon as possible. Simply switching wallet applications, changing passwords, or reinstalling the extension will not eliminate the risk.Upon inspection, no related malicious code was found in the Fearless Android and Apple mobile versions; however, if the mobile wallet has previously imported the same keys used by the browser extension, those keys should still be considered compromised.

Odaily reports that the Polkadot community recently submitted a proposal on the SubSquare platform titled "DOT DAO Strategy Mandate," advocating for a shift in the DAO's strategic focus from ecosystem expansion and total value locked (TVL) growth to end-user acquisition and real-world use cases, and planning to build a user-facing Polkadot Product Platform.Another core component of the proposal is the launch of a permissionless DOT-collateralized stable asset called dotStables, with priority support for dotUSD. The asset adopts a collateralization model similar to Liquity, aiming to ultimately convert stablecoin demand into demand for DOT. In terms of platform design, it will be compatible with existing parachain infrastructure and emphasize a freemium model, mobile-first approach, self-custody, privacy protection, and login-free user experience. Currently, the proposal is still in the governance preparation stage.

Odaily — Polkadot has officially announced that the stablecoin dotUSD has officially launched on the Polkadot network. The stablecoin has no single issuing company or controlling entity; instead, it is managed by the DOT DAO through the OpenGov on-chain governance mechanism. Polkadot stated that dotUSD aims to become a native stablecoin governed by the network itself, thereby reducing reliance on centralized issuing institutions.

Odaily News, Bitfinex Alpha report shows that Bitcoin has been trading sideways in the 77,100 to 81,300 USD range over the past 20 trading days, with the current price approaching the key support level at the lower end of the range. If it breaks above 81,300 USD, the volume vacuum above could push the price quickly up to 86,500 USD. In the options market, protection has been moved to contracts expiring on September 18 ahead of the Federal Reserve's interest rate decision.

For the first time this week, open interest in altcoin perpetual contracts has surpassed that of Bitcoin, a historical pattern often accompanied by market correction risks.

Odaily News: The Polkadot community has initiated OpenGov Proposal No. 1944, aiming to create a native decentralized stablecoin called dotUSD and establish it as the primary stable value asset within the Polkadot ecosystem. The proposal is currently undergoing governance voting. According to the proposal, dotUSD will adopt an over-collateralization mechanism, allowing users to mint dotUSD by locking DOT in the future. The system will also include a stability pool, liquidation mechanism, and redemption mechanism to maintain its peg to the US dollar. The proposal plans to use funds from the Polkadot treasury to provide initial liquidity for the DOT/dotUSD liquidity pool, with $2.5 million in USDT used to mint dotUSD and an additional $2.5 million worth of DOT allocated to the liquidity pool, bringing the total initial funding to $5 million. dotUSD is planned to launch in phases, with the first phase using USDT as reserve backing for minting, and the second phase introducing a full DOT collateral vault, oracle, stability pool, liquidation, and redemption mechanisms.

Odaily News - The latest disclosure from 21Shares' Polkadot ETF (TDOT) shows that in Q2 2026, the fund sold DOT tokens to pay staking rewards, incurring approximately $4.52 in realized losses for every $1 in distributions generated.According to regulatory filings, TDOT sold 98,505 DOT in Q2, generating approximately $107,500 in cash to pay staking rewards to shareholders. However, due to the sharp decline in DOT's price, these sales confirmed approximately $485,600 in losses.Data shows that DOT fell approximately 34% in Q2 2026, with a cumulative decline of 76% over the 12 months ending June 30. Since TDOT shareholders receive USD-denominated distributions rather than DOT staking rewards directly, the fund must sell DOT to convert to cash payments, thereby locking in losses in a low-price environment. In Q2, TDOT paid shareholders approximately $0.14698 per share in distributions, but the fund's share price fell from $14.95 to $9.86 during the same period, a decline of roughly 34%. Staking yields did not offset the losses from the decline in asset prices. (Protos)
