South Korean exchanges Upbit and Bithumb have suspended deposits for Synthetix (SNX) tokens after it was flagged by the Digital Asset Exchange Alliance (DAXA) for potential risks.

DAXA, the self-regulatory organization establishing industry standards for South Korean exchanges, designated SNX as a cautionary item. 

Assets receiving this designation typically undergo rigorous evaluations to determine whether trading can continue or if delisting becomes necessary.

Exchanges may take action, such as adding a warning tag to the asset and urging investors to take caution when engaging with the asset. Trading platforms can also perform additional measures, like blocking deposits or suspending trading support temporarily. 

Upbit and Bithumb block SNX deposits

In response to the designation, the biggest exchanges in South Korea announced that they are blocking deposits for SNX tokens on their platforms. 

Upbit announced that it added a trading caution ticker and suspended token deposits. The exchange said it had been monitoring the developments related to the Synthetix USD (sUSD) depegging. It added that this event may damage investors from potential volatility, as SNX is used as collateral for sUSD. 

The exchange added that it had determined a lack of use cases for the asset, which may cause investors to suffer losses. Upbit said it would conduct a comprehensive review to decide whether to delist the asset or resume normal operations for the token. 

Bithumb has also blocked deposits for SNX and added a cautionary tag for the tokens. However, the exchange said this decision could be overturned depending on internal circumstances. If the reason for the designation is resolved, Bithumb said it would lift the restrictions. 

Korbit and Coinone also published investor alerts to caution traders about the asset. The two exchanges also added cautionary tags to SNX tokens to alert investors who may want to trade the tokens. 

Cointelegraph reached out to Synthetix for comment but did not get a response by publication.

sUSD struggles to recover dollar peg

On April 10, the sUSD stablecoin dropped to a five-year low of $0.83 after struggling to maintain its dollar peg in the first quarter of 2025. With the stablecoin being collateralized by the project’s native asset, Cork Protocol co-founder Rob Schmitt compared the token to Terra USD (UST), which collapsed in 2022. However, Schmitt said that sUSD has a “more manageable” debt system. 

On April 18, the stablecoin dipped further to $0.68, with SNX falling by 26% in a 30-day period. A Synthetix spokesperson told Cointelegraph that their team has short, medium and long-term plans to mitigate the risks. 

On April 21, Synthetix founder Kain Warwick threatened SNX stakers with “the stick” if they didn’t take up a newly launched staking mechanism to fix the sUSD depeg. The executive said they may put extra pressure on stakers if they don’t see enough momentum on the newly implemented mechanism. 

Since the warning, sUSD prices increased by 27%. On April 24, the stablecoin briefly reached $0.87. However, the token still failed to recover its dollar peg.
