Polymarket will upgrade the settlement rules for the cryptocurrency rise and fall market: abandoning the single price snapshot and switching to a time-weighted average price

According to official news, the prediction market Polymarket announced a significant adjustment to its settlement mechanism for cryptocurrency price fluctuation markets starting from August 7, to protect market integrity. From midnight UTC on that day, the affected markets will no longer settle based on a single price snapshot at a specific time but will instead use a time-weighted average price.Markets of different durations correspond to different TWAP windows: all cryptocurrency 5-minute markets will use a 30-second TWAP, 15-minute markets will use a 60-second TWAP, and 4-hour markets will also use a 60-second TWAP. The previous single snapshot settlement method was prone to price manipulation during periods of low liquidity, and this change is a proactive reinforcement of the market integrity system by Polymarket after facing regulatory scrutiny.To support this transition, Polymarket will inject $1 million in liquidity rewards into all affected markets throughout August. On the technical side, Chainlink TWAP testnet data streams are now available, and mainnet data streams along with Polymarket real-time data stream services will go live on August 4, at which point developers can access TWAP prices directly through Chainlink Data Streams or Polymarket's public WebSocket.

first_img The South Korean Financial Commission plans to submit a unified digital asset bill, while the opposition party is simultaneously pushing to abolish the cryptocurrency tax

According to Edaily, the Financial Services Commission (FSC) of South Korea plans to jointly draft a unified government bill for the "Basic Law on Digital Assets" with the ruling Democratic Party, covering the issuance and circulation of stablecoins, business rules for digital assets, exchange admission requirements, information disclosure, internal control, and system resilience standards. Currently, there are 10 related bills pending review in the National Assembly, but there has not yet been consensus on core disputes such as whether the issuers of won-pegged stablecoins must be bank holding companies and whether to impose shareholding restrictions on major exchanges. The FSC has not yet determined the submission date for the bill.Meanwhile, the opposition party's People Power Party lawmaker Song Yeon-sik submitted a proposal to abolish the cryptocurrency income tax amendment to the National Assembly's Finance and Economy Planning Committee for review on Wednesday. Additionally, a tax abolition petition supported by over 50,000 people is also expected to be submitted to the petition subcommittee. According to the current plan, starting from January 1, 2027, cryptocurrency transfers or lending income exceeding 2.5 million won per year will face a 20% income tax plus a 2% local tax. The government and the ruling party support the timely implementation, while the opposition party believes it is unfair to tax cryptocurrencies when most ordinary stock investors remain tax-exempt.
