Upbit, South Korea's largest crypto exchange, will list the B3 Korean won trading pair, with trading set to begin at 13:45 local time on May 7.
B3 is a layer-3 blockchain built on Base, the Ethereum layer-2 network, and inherits the OP Stack tooling that underpins the Optimism Superchain. A Korean won pair on Upbit is one of the more consequential on-ramps a domestic project can win — Upbit dominates retail flow in South Korea and the won pair clears the local fiat friction that keeps offshore DEX routes expensive for Korean traders.
Why it matters
For a layer-3 still in early discovery, a marquee venue listing does the work of months of organic growth: liquidity, price discovery, and credibility concentrate on Upbit's order book within hours. B3 inherits Base's developer ecosystem by sitting on the same OP Stack, so the listing also exposes the broader Base-aligned project pool to Korean retail demand.
Market impact
The first 24-48 hours of trading typically set the volume baseline a won pair will carry for its first quarter — and that baseline tends to anchor where Korean-language coverage follows. Watch the B3-KRW spread versus offshore USD pairs for early signs of a Korean premium.
