Extended will migrate its settlement operations to the Arc Layer 1 blockchain during the week of October 19. Users are required to convert existing USDT and wBTC holdings to USDC or cirBTC by October 21 at 8 a.m. ET to avoid account restrictions.
Why it matters
The migration reflects the exchange's shift to a new network that will not support legacy USDT and wBTC assets. Failing to meet the conversion deadline will result in automated trading and margin restrictions, with un-converted positions closed at the mark price.
The conversion process offers a 1:1 exchange rate plus a 0.50% premium for users. Platform deposits and withdrawals will undergo a mandatory two-hour pause during the transition.

Market Dynamics
The migration to the Arc Layer 1 blockchain marks a structural shift in how decentralized exchanges handle settlement assets. This move signals a broader transition toward specialized networks designed to host high-volume real-world-asset perpetual markets.
Users must proactively convert their holdings to avoid forced liquidations and margin restrictions on their accounts. Investors should ensure all sub-accounts are updated before the two-hour service window begins to prevent temporary loss of access to funds.
The takeaway
Proactive management of digital assets is essential during platform infrastructure migrations to prevent automated position closures. Investors should prioritize updating their account settings well before the official deadline to maintain uninterrupted portfolio access.
