Extended, the decentralized finance platform that recently announced a migration of its settlement layer from Starknet to the Arc network, has issued a stark warning to users who maintain balances of at least one USDT or wBTC in any sub‑account. The notice states that these holders must either convert their assets to the new settlement token or withdraw them entirely before a specified cutoff date, or risk having their positions automatically closed by the protocol.
The migration to Arc is part of Extended’s broader strategy to improve transaction throughput, reduce gas costs, and enhance overall network security. Starknet, while praised for its scalability, has faced intermittent congestion and higher fee volatility during peak usage periods. Arc, by contrast, offers a more predictable fee structure and a governance model that aligns closely with Extended’s roadmap for cross‑chain liquidity aggregation.
According to the platform’s communication, the deadline for converting or withdrawing USDT and wBTC balances is set for October 31, 2024. However, earlier drafts of the notice referenced a September 30 deadline, creating confusion among the community. Extended has since clarified that the final deadline remains October 31, but it urges users to act promptly to avoid any unintended liquidation of their positions.
For users, the forced closure mechanism is designed to protect the protocol’s solvency during the transition. If a sub‑account retains a qualifying balance after the deadline, the system will automatically sell the assets at prevailing market rates to settle any outstanding obligations. This process could result in slippage, especially in volatile market conditions, and may leave users with less than their original holdings.
From a risk management perspective, the move underscores the importance of active portfolio monitoring in the DeFi space. Investors who rely on set‑and‑forget strategies must now incorporate migration timelines into their operational checks. The requirement to act on balances as low as one USDT or wBTC reflects Extended’s commitment to eliminating dust‑level positions that could complicate the settlement process.
Analysts view the migration as a positive step for Extended’s long‑term scalability. By leveraging Arc’s modular architecture, the platform can support higher transaction volumes without compromising on finality or security. Moreover, the shift may attract new liquidity providers who were previously deterred by Starknet’s fee unpredictability.
Nevertheless, the abrupt communication style has drawn criticism from some community members who argue that clearer guidance and a unified deadline would have mitigated confusion. Transparency in migration plans is essential for maintaining user trust, especially when forced closures are on the table.
Investors holding USDT or wBTC on Extended should verify the exact balances in each sub‑account, initiate conversion to Arc‑compatible assets, or withdraw funds to an external wallet before the October 31 cutoff. Failure to do so could result in automatic liquidation, potential tax implications, and a loss of capital.
Overall, the settlement shift represents a pivotal moment for Extended as it seeks to solidify its position in the competitive DeFi landscape. By moving to a more efficient settlement layer, the platform aims to deliver faster trade execution, lower fees, and a more resilient infrastructure for future growth.
