Upbit pushes JPYC launch to 3 p.m. KST, PYUSD unchanged

Upbit announced a three‑hour postponement of JPYC trading on September 17, shifting the start time from 12:00 p.m. to 3:00 p.m. KST. The delay applies to all three JPYC pairs – KRW, BTC and USDT – and does not affect the concurrently listed PayPal USD (PYUSD), which will still begin trading at noon.

JPYC launch details

When trading begins, JPYC can be exchanged against the South Korean won, Bitcoin and Tether. Deposits and withdrawals are limited to the Ethereum network, using contract address 0xE7C3D8C9a439feDe00D2600032D5dB0Be71C3c29. Upbit warned users to verify the network and contract before transferring funds, as unsupported deposits may require a lengthy return process.

PYUSD schedule remains

PYUSD retains the original noon start time for its KRW, BTC and USDT markets. Deposits and withdrawals for PYUSD are also restricted to Ethereum, with contract address 0x6c3ea9036406852006290770bedfcaba0e23a0e8.

Trading controls for new listings

• Buy orders are blocked for roughly five minutes after the opening.
• Sell orders priced more than 10 % below the reference price are restricted for the same period.
• Only limit orders are allowed for about two hours after launch; other order types are disabled.
• Minimum order sizes: 5,000 won (KRW), 0.00005 BTC, 0.5 USDT.

Background on JPYC

JPYC Inc. received registration as a Japanese funds‑transfer service provider in August 2025, allowing it to issue a yen‑linked stablecoin redeemable 1:1 for Japanese yen. The token is backed by yen‑denominated deposits and government bonds and circulates on Ethereum, Avalanche and Polygon. Upbit’s listing supports only the Ethereum version.

Pricing reference

Upbit used CoinMarketCap data for initial pricing, showing JPYC at 8.81 won at 9:40 a.m. KST on the listing day, compared with a prior reference of 8.78 won. These figures are reference prices and do not reflect post‑launch market activity.
