ETHGas surged after Upbit named it among four new additions to its South Korean marketplace, climbing roughly 11% in the immediate market reaction and outpacing the other newly listed tokens.

Upbit said it would add trading for Biconomy's BICO, Bubblemaps' BMT, Nillion's NIL and ETHGas' GWEI, with BTC and USDT pairs available for each asset. The four projects sit in distinct niches: Biconomy builds account-abstraction and transaction-relaying infrastructure, Bubblemaps offers wallet-cluster analytics for on-chain data, Nillion is a privacy-focused compute network, and ETHGas is an Ethereum gas-fee data platform. Upbit, operated by Seoul-based Dunamu, is South Korea's largest crypto exchange by trading volume, and its listing notices are closely watched across token communities. The exchange did not announce Korean won pairs, an important limitation in a market where KRW liquidity can often drive the sharpest listing moves; Upbit typically opens BTC- and USDT-denominated markets before, or instead of, KRW pairs, which require a separate designation review.

A familiar listing pop, led by GWEI

All four tokens rose after the notice. GWEI posted the largest gain, while BMT and BICO each advanced by more than 7%, according to market data cited alongside the announcement. NIL registered the smallest move of the group, though it was still higher on the day.

Trading activity accelerated as prices climbed. ETHGas volume jumped nearly 198% over 24 hours to about $11.1 million, while BICO recorded roughly $34.5 million in volume. BMT and NIL also saw increases in turnover, suggesting traders were positioning ahead of the venue's launch rather than merely reacting to thin liquidity. Of the four, BICO is the most seasoned by trading history, having listed on major global exchanges since 2021, while the other three launched considerably more recently.

Opening schedule and trading restrictions remain in focus

The precise start time appeared to shift. One account of the listing said Upbit delayed the launch by three hours to 16:00 Korea Standard Time, while another cited an initial 13:00 KST opening. Investors should rely on the exchange's latest notice, particularly because deposits, withdrawals and trading access may not begin simultaneously.

Upbit is expected to apply its standard safeguards for new listings. These include a short restriction on buy orders after trading opens, limits on deeply discounted sell orders, and a period in which only limit orders are accepted. Deposits and withdrawals are supported only on the networks specified by the exchange. Beyond the opening, the checkpoints typically watched next are whether Upbit later designates KRW pairs for the assets, when the temporary order restrictions lift, and any changes to the supported deposit networks — all of which the exchange communicates through its official notices.
