- Binance ends MANTRA (OM) ERC20 deposits and ERC20/BEP20 withdrawals on Sept 26.
- Binance Futures delists BSWUSDT contract; all positions settled by Sept 15 deadline.
- Risk controls include IOCO liquidations, ADL system, and margin adjustments.
Binance confirmed it will halt support for certain MANTRA (OM) transfers later this month. Starting September 26, 2025, at 03:00 UTC, deposits made through the Ethereum (ERC20) network will no longer be credited, and withdrawals processed via both BNB Smart Chain (BEP20) and Ethereum (ERC20) will be disabled.
The company warned that deposits sent through ERC20 after the deadline will not appear in user accounts and may result in permanent loss of funds. Other supported networks will remain available for MANTRA (OM) deposits and withdrawals.
Binance Announcement on Network Restrictions
The changes affect two specific transaction categories:
- Deposits through Ethereum (ERC20).
- Withdrawals through BNB Smart Chain (BEP20) and Ethereum (ERC20).
Binance stated that deposits or withdrawals attempted on these networks after the cutoff will not be recoverable. According to the announcement, users must switch to alternative networks that will continue to support the token. The platform also emphasized that in cases where translations differ, the original English announcement should be treated as the accurate version.
Previous Delisting of BSWUSDT Futures
The latest update follows an earlier move on the derivatives side. On September 15, 2025, at 09:00 UTC, Binance Futures delisted the USDⓈ-M BSWUSDT perpetual contract. In preparation for the removal, the platform required all open positions to be closed.
Trading restrictions were introduced in stages. At 08:30 UTC, new positions were blocked, while remaining positions were automatically settled at 09:00 UTC. After this settlement process, the contract was fully removed from the exchange’s offerings.
Liquidation and Risk Management Process
During the last hour before settlement, the Futures Insurance Fund was not available to manage liquidations. Instead, affected positions were processed through a single Immediate or Cancel order (IOCO). If the IOCO reduced exposure sufficiently to meet margin requirements, liquidation stopped. If not, the Auto-Deleveraging (ADL) system was applied.
Binance Futures also outlined additional protective measures that could be enacted without prior notice in periods of heightened volatility. These included changes to leverage limits, position sizes, margin tiers, and funding rates. Updates to the index components and the use of the Last Price Protected mechanism to update mark prices were also noted as possible interventions.
Binance advised users to review these deadlines carefully, for MANTRA (OM), deposits through ERC20 and withdrawals via ERC20 or BEP20 must be completed before September 26 at 03:00 UTC. For the BSWUSDT contract, users were instructed to close positions before delisting to avoid automatic settlement.
