   GMO-Z.com Trust Company, Inc., the issuer of GYEN, is winding down the GYEN stablecoin. Coinbase will convert all GYEN held on Coinbase to USDC from October 26 - 30, 2026. Send and receive support for GYEN will be disabled on Coinbase from October 26, 2026. Any GYEN that remains on platform as of October 26, 2026 will be converted to USDC from October 26 - 30, 2026. Your tokens will be converted at the market rate at the time of conversion. There will be no transaction fees associated with the conversion. If you do not wish for your GYEN to be converted to USDC please send it to a compatible self-custody wallet before October 26, 2026. Tax consequences may apply. Please consult your local tax professional. After the conversion is complete, you will no longer be able to withdraw GYEN and Coinbase will no longer support deposits of GYEN. Please do not send GYEN to your Coinbase deposit address, as these deposits may not be recoverable and will not be converted to USDC.
