Upbit listed Block Street (BSB) on its KRW, BTC and USDT markets on August 7, 2026, and Bithumb added a won market the same week. On October 7 the token of the tokenized-equities protocol trades at $0.0974 with a market cap near $23 million, and Upbit's won pair is still active.

Correction, October 7 The first version of this page called Upbit's listing BSB's first Korean won venue. Bithumb announced its own won market for BSB in the same week, and CoinGecko shows both exchanges with active BSB/KRW pairs. The first-venue claim is removed.

Where it stands

Upbit announced BSB on August 6 and opened trading at 3 p.m. Korea time on August 7. Deposits and withdrawals started on the Ethereum network only. Upbit blocked buy orders for about the first five minutes, restricted sell orders priced more than 10 percent below the previous close, and allowed only limit orders for roughly two hours.

On listing morning Upbit's reference price was 222.34 won, against a previous close of 211.09 won, crypto.news reported. Bithumb announced its own BSB won market on August 6, according to a Bloomingbit notice headline. On October 7 Upbit's BSB/KRW pair carried about $363,000 of daily volume and Bithumb's about $66,000.

Three pairs at once is the full treatment, since plenty of tokens debut on a single USDT market and wait months for a won pair. As our listings guide explains, the pair choice is information: Upbit bet that Korean retail wanted direct won exposure to the tokenized-stock theme.

Korea is now a small part of BSB trading. CoinGecko's venue table for October 7 shows a PancakeSwap pool on BNB Chain, the GroveX exchange and Bitget ahead of Upbit.

The protocol and the supply

Block Street pitches itself as infrastructure for onchain capital markets, with tokenized equities and real-world assets as the target inventory. Its Unified Liquidity Layer tries to join liquidity that sits fragmented across issuers, blockchains and venues, so a tokenized share can be borrowed against, margined, hedged or arbitraged. Plume's RWA chain pursues the same thesis from the network side, and Block Street comes at it from market structure.

The project closed an $11.5 million strategic round in October 2025 led by Hack VC, with Generative Venture, DWF Labs, StudioB and Bridge34 participating. The token already traded on offshore venues including Bybit before the Korean debut, and Binance ran a BSB trading rewards campaign on its own platform.

Risks and open questions

The whitepaper fixes total supply at 1 billion BSB, with 207.75 million tokens, about 20.775 percent, expected to circulate around the token generation event. CoinGecko now counts 236.3 million in circulation. About three quarters of the supply is therefore still to arrive, and each future unlock is a scheduled seller. We found no published unlock calendar beyond the whitepaper split.

On October 7, CoinGecko showed BSB at $0.0974, down about 11 percent over 30 days, with $6.32 million of daily volume. A float this thin amplifies moves in both directions. Our tokenomics guide covers how to weigh a float this size against a listing candle.

The theme has real activity behind it. A tokenized share is a blockchain token that tracks a stock held by an issuer, and exchanges keep widening their offerings of them while issuers keep adding names. The BSB token sits one layer above that: it belongs to the market plumbing, not to any single stock, so its value depends on whether the protocol attracts the trading, borrowing and hedging it is designed for. The whitepaper sketches those mechanics, and the market has not yet stress-tested them.

What to watch next:

  • Any unlock schedule or supply update from the project.
  • Whether Upbit and Bithumb volume holds near $363,000 and $66,000.
  • New venues beyond the offshore exchanges and pools shown above.
