Coinone too Halt MASA (Ethereum ERC20) Trading Support
Table of Contents
Coinone, a leading virtual asset exchange, has announced the termination of trading support for MASA (Ethereum ERC20) due to concerns regarding past security incidents and clarity issues.

Reason for Terminating MASA Trading Support
On December 5, 2025, MASA was initially designated as a cautionary trading item. This designation stemmed from a lack of sufficient follow-up measures addressing previous security breaches, coupled with transparency concerns surrounding process changes and the disclosure of critically important information, perhaps causing harm to users. Coinone thoroughly reviewed the situation, requesting clarifying data from MASA, but steadfast that the initial concerns had not been adequately resolved. Therefore, the exchange opted to end trading support for MASA to safeguard it’s user base.

- Transaction History: Transaction history will be preserved even after withdrawal support ceases.

- Technical Support: Technical support for MASA, including mainnet changes, contract updates, airdrops, token swaps, and network updates, may be discontinued, potentially leading to loss of value.
