ETHGas has received a major boost from new Upbit listings after South Korea's largest cryptocurrency exchange revealed that it will add GWEI to its platform as one of four new tokens. The coin rose by nearly 11% shortly after the announcement, making it the best performer among the four newly listed assets.

Upbit, operated by Seoul-based Dunamu and one of the most heavily traded cryptocurrency venues in the world, said it will launch trading for four tokens: BICONOMY's BICO, Bubblemaps' BMT, Nillion's NIL, and ETHGas' GWEI. The tokens will be available for trading via BTC and USDT pairs. Upbit did not, however, mention KRW pairs, meaning the new assets will not initially trade against the Korean won on a platform whose won-denominated markets account for a large share of domestic crypto activity.

The exchange shared the listing notice on X on August 21, 2026:

GWEI Leads the Four New Additions

The surge in activity around GWEI indicates considerable interest from traders ahead of the start of trading in the new Upbit listings. Listings of this kind are typically associated with increased visibility for a token and can be accompanied by strong price action and trading volumes. For tokens seeking broader distribution, access to Upbit's large South Korean retail user base is widely regarded as a meaningful liquidity milestone. GWEI's near-11% gain made it the standout of the group, outpacing BICO, BMT and NIL in the immediate reaction to the announcement.

Listing Schedule Remains in Focus

It is not yet clear exactly when the new markets will open. According to one report, Upbit has delayed the opening of the markets to 4 p.m. Korea Standard Time, whereas another report mentions an opening at 1 p.m. KST, the same start time listed in the exchange's notice. Discrepancies between early reports and official notices are not unusual in the hours around a new listing, which is why the exchange's own notice page is the authoritative source. Users must verify official announcements from Upbit for details about the exact timing of the markets.

The deposit and withdrawal process can also differ depending on the exchange's policy. Under South Korea's travel-rule regime, which has required exchanges to verify the origin of cryptocurrency deposits since March 2024, incoming transfers must come from an exchange or from a personal wallet whose ownership has been confirmed, a step that can add time to first-time deposits of a newly listed asset.

Trading Restrictions May Apply

As part of the standard procedure it applies to newly listed tokens, Upbit could impose certain trading restrictions for a period of time. These could include limits on buy orders at the start of the trading day or on sell orders placed well below the reference price, among others.

Deposits and withdrawals will be subject to the particular blockchain networks supported by Upbit. Users should ensure they are selecting the right network for the newly listed asset.

The latest Upbit listings have brought yet another batch of cryptocurrencies to one of the most closely monitored cryptocurrency exchanges in South Korea, with GWEI emerging as the immediate standout of the announcement. For those tracking the rollout, the open questions are the confirmed market opening time, whether Korean won pairs follow later, and when any early trading restrictions are lifted.
