Grinex Exchange USDT Hack: Trading Halt After $13.7M Theft

Published: 2026-04-17 08:05:21 |

Grinex Exchange has halted trading and withdrawals after a security breach linked to a reported USDT hack worth about $13.7M. The exchange says funds were taken from 54 wallet addresses and that the operation was highly sophisticated. Grinex shared evidence with law enforcement and filed a criminal complaint related to the compromised infrastructure. On-chain tracing firms TRM Labs and Elliptic report the stolen assets moved across multiple addresses and were quickly converted into other tokens, including TRX and ETH. Elliptic estimates that roughly $15M in Tether (USDT) left Grinex-controlled accounts. The reported “rapid conversion/chain-hopping” may have been used to reduce the chance of USDT freezing and slow down detection. The incident is expanding under broader scrutiny. TRM Labs says two wallets connected to TokenSpot transferred about $5,000 to a consolidation address allegedly tied to the attacker, and it identified 16 additional related addresses. For crypto traders, the key takeaway is counterparty and stablecoin custody risk. In the short term, the Grinex Exchange halt can tighten liquidity for local on/off-ramps and raise risk-off sentiment around USDT pairs. Over the longer term, repeated USDT-related hacks can increase scrutiny of centralized platforms and stablecoin routing behavior, affecting confidence in stablecoin settlement integrity across exchanges and regions.

Bearish

This news is likely bearish for USDT-related trading flows. The Grinex Exchange USDT hack and the subsequent halt directly undermine confidence in USDT custody and stablecoin settlement on a centralized venue. Even though the stolen funds were reportedly converted into TRX and ETH, the key point for traders is that significant USDT outflows occurred and the attacker’s behavior (rapid conversion/chain-hopping) suggests the risk is hard to contain operationally. Short term, traders often de-risk when an exchange is frozen, which can reduce USDT liquidity and widen spreads on USDT pairs. Longer term, recurring stablecoin incidents increase compliance and risk-management scrutiny, potentially raising costs and reducing willingness to route large flows through similar venues—typically negative for near-term USDT demand despite not being a direct protocol-level failure.
