On September 28, 2026, Bithumb said it would add **PayPal USD (PYUSD)** and **Quark AI (Q)** to its **KRW market**, with trading support from **15:00 KST** (08:00 CEST).

Per Blockmedia's September 28 report (13:57 KST) citing Bithumb's notice, PYUSD deposits and withdrawals use **Ethereum only**; Quark AI uses **BNB Smart Chain only**. Both deposit/withdraw windows were set to open within about two hours of the notice post.

Stablecoin Insider treats this as a named Korea venue listing of a Paxos-issued dollar stablecoin on Bithumb's won book. It is a KRW-focused add, not a multi-market package like [Upbit's September 17 PYUSD and JPYC listing](https://stablecoininsider.org/upbit-lists-pyusd-and-jpyc/) across KRW, BTC, and USDT.

📌

As of September 28, 2026 (Blockmedia report of Bithumb notice; TechFlow flash same day): Bithumb adds PYUSD and Quark AI (Q) to the KRW market. Trading from 15:00 KST (08:00 CEST). PYUSD network: Ethereum only. Q network: BNB Smart Chain only. Early trading limits apply (about 5 minutes buy ban; sell band minus 10 percent / plus 100 percent of reference; about 2 hours limit-order-only).

### Key Takeaways

- Bithumb listed PYUSD on the KRW market with trading from September 28, 2026 at 15:00 KST (08:00 CEST).
- PYUSD deposits and withdrawals on Bithumb are Ethereum only; other networks are not supported.
- Quark AI (Q) was co-listed on KRW the same day on BNB Smart Chain only (secondary to the PYUSD story).
- Early trading limits include about 5 minutes of buy bans, a minus-10-percent / plus-100-percent sell band versus reference, and about 2 hours of limit-order-only trading.
- Unlike Upbit's multi-market PYUSD package, Bithumb's add is KRW-focused per the Blockmedia and TechFlow summaries of the notice.

⚠️

Named downside for operators: Travel Rule rules apply, so deposits from unsupported VASPs may not credit and returns can take a long time. Wrong-network sends (non-Ethereum for PYUSD) are not supported. Early books sit under temporary order limits, so treat first prints as venue quotes under constraint, not free float.

## What Bithumb listed and when

Bithumb announced new KRW market support for **페이팔유에스디(PYUSD)** and **쿼크에이아이(Q)**. [TechFlow's same-day flash](https://www.techflowpost.com/en-US/newsletter/138017) and Blockmedia both attribute the schedule to Bithumb's official notice board.

Trading for both assets was set to begin at **2026-09-28 15:00 KST** (08:00 CEST). Deposits and withdrawals for each asset were described as opening within two hours of the notice post.

Stablecoin Insider could not reliably scrape the live HTML of [Bithumb's notice board](https://feed.bithumb.com/notice) at publish time (Cloudflare / SPA). Facts below follow Blockmedia's attributed summary of that notice; operators should re-check the board before depositing.

## Early trading limits and Travel Rule notes

For a safer open, Bithumb said it would apply temporary order limits after trading starts:

- About the first 5 minutes: buy orders restricted.
- Same window: sell orders at or below minus 10 percent of the reference price, or at or above plus 100 percent of the reference price, restricted.
- About the first 2 hours: only limit orders allowed; other order types restricted.

Those order-limit details are from Blockmedia's attributed summary of the Bithumb notice; see also [TechFlow's same-day flash](https://www.techflowpost.com/en-US/newsletter/138017).

On deposits and withdrawals, Bithumb warned that Travel Rule compliance means transfers only with supported VASPs. Credits from unsupported venues may not reflect, and returns can take a long time. Users must confirm the asset address scheme and network on the deposit screen.

## Who issues PYUSD

PayPal USD is a 1:1 USD stablecoin issued by **Paxos Trust** and distributed through PayPal and Venmo. See [Paxos PYUSD mainnet docs](https://docs.paxos.com/guides/stablecoin/pyusd/mainnet) and [PayPal's PYUSD help article](https://securepayments.paypal.com/us/cshelp/article/what-is-paypal-usd-pyusd-help1005).

Bithumb's public summary did not republish a contract address in the Blockmedia write-up, so Stablecoin Insider is not inventing one here. Match the live Bithumb deposit screen (and issuer docs) before any transfer. For mint/redeem and merchant rails outside the Korea spot book, see [how to mint and redeem PYUSD with Paxos Orchestrations](https://stablecoininsider.org/how-to-mint-and-redeem-pyusd-with-paxos-orchestrations/) and [how to enable PayPal PYUSD Settlement for merchant rewards](https://stablecoininsider.org/how-to-enable-paypal-pyusd-settlement-for-merchant-rewards/).

[Upbit Lists PYUSD and JPYC on KRW, BTC, and USDT MarketsSeptember 17, 2026: Upbit's multi-market PYUSD and JPYC listing for comparison with today's Bithumb KRW-only add.![](https://stablecoininsider.org/favicon.ico)Stablecoin Insider](https://stablecoininsider.org/upbit-lists-pyusd-and-jpyc/)

## Why this listing matters in Korea

Bithumb is one of Korea's major won venues. A KRW book for PYUSD gives Korean won traders a PayPal-linked dollar stablecoin on a second large domestic exchange after Upbit's September 17 multi-market add.

Circle's Korea posture is a separate track; see [Circle expands in South Korea](https://stablecoininsider.org/circle-expands-in-south-korea/) for USDC-side context. Today's object is Bithumb's PYUSD KRW listing, not a new Korean won stablecoin.

**Stablecoin Insider's take:** this is KRW liquidity plumbing for a Paxos-issued dollar stablecoin on Bithumb. Operators should watch Ethereum-only deposit rails, Travel Rule VASP lists, and the two-hour limit-order window before treating early KRW prints as deep liquidity.

## What operators should do next

Confirm Ethereum-only deposit/withdraw for PYUSD on Bithumb before funding. Re-check the official notice board and the on-screen deposit network.

Expect thin early books under temporary trading limits. Treat KRW reference prints as venue quotes under constraint, not issuer redemption prices.

If the goal is mint, redeem, or merchant PYUSD settlement rather than Korea spot trading, start with the Paxos Orchestrations and PayPal Settlement how-tos, not the Bithumb order book.
