South Korean cryptocurrency exchange Upbit has added B3 to its Korean Won market, giving local traders direct access to Base-linked tokens.
The deal was originally scheduled for May 7th at 13:45 KST, but Upbit later changed the start time to 14:00 KST.
B3 is a layer 3 blockchain built on Base, Ethereum’s layer 2 network developed with the OP stack. Listing on Upbit gives the token access to one of the most active retail cryptocurrency markets in Asia.
Exchanges set early trading limits
According to Upbit, deposits and withdrawals only support B3 through the Base network. The exchange also asked users to verify their contract address before transferring funds. Deposits made via unsupported networks may result in a longer refund process.
Exchanges placed normal restrictions on early trading. Buy orders were restricted for about five minutes after the release. Upbit also limited low-price sell orders and also limited non-limit order types by approximately two hours.
Upbit warns, “If a certain level of liquidity cannot be secured after the start of deposit and withdrawal services, the start of transaction support may be postponed.” The notice leaves the exchange with room to adjust trades if market depth is weak.
B3 joins recent wave of Upbit listings
This listing comes after several Upbit market additions brought renewed attention to the selected tokens. As reported by crypto.news yesterday, Dogwifhat rose after Upbit added a WIF trading pair against KRW. $BTCand $USDT The report also noted that an initial public offering could expose traders to sharp price fluctuations.
Previously, crypto.news reported that Centrifuge soared over 180% after Upbit announced trading support. Another report said that Internet Computers increased its market value by about $100 million after Upbit began trading ICP against the Korean won. $BTCand $USDT.
These examples show why the new KRW pair attracts the market’s attention. These create direct access to the local currency and can bring sudden liquidity from Korean retail traders.
OP Stack links add market context
B3’s Base and OP Stack links also fit into Upbit’s broader infrastructure trends. Crypto.news reported this week that Upbit has partnered with Optimism to build GIWA Chain, an Ethereum layer 2 network using the OP stack.
According to the report, GIWA Chain plans to have Upbit run its own infrastructure under Optimism’s self-managed enterprise structure. Exchanges operate their own sequencers that control the order of transactions and collect network fees.
The B3 list is separate from GIWA Chain, but both are related to OP Stack-based blockchain activities. For traders, this listing positions B3 within the Korean Won market while increasing visibility of the Base-link Layer 3 project.
