The U.K. arm of Coinbase appears to be dropping support for the privacy-focused cryptocurrency zcash.
According to customers, Coinbase UK is sending letters out warning people that they will need to convert their zcash (ZEC) holding, or remove them to an external wallet, by Aug. 26.

The cryptocurrency exchange gave no specific reason for the removal of the cryptocurrency, but said all remaining ZEC balances on Aug. 26 will be automatically converted to British pounds in users accounts.
The Electric Coin Company, developer of zcash, appeared to confirm the news, saying in a tweet on Friday:
“Those affected by @coinbase UK issues: this is limited to Coinbase UK only. UK residents can still buy/sell Zcash through @cex_io. No other exchanges in the UK affected.”
It further said “To pre-empt speculation, we confirm that Zcash is 100% compatible with UK regulations & KYC/AML requirements.”
In its guidance released at the end of July, the U.K.’s financial watchdog, the Financial Conduct Authority, said that while some forms of crypto assets may fall under its regulatory remit, “exchange tokens” such as bitcoin and ether do not. That category would appear to include zcash.
The British tax agency, HM Revenue & Customs, has recently been sending out letters demanding that cryptocurrency exchanges – including Coinbase, eToro and CEX.IO – reveal customers’ names and transaction histories in a bid to claw back unpaid taxes, industry sources told CoinDesk.
Zcash allows users the option to hide (or shield) details of their transactions using a type of zero-knowledge proof called zk-SNARKs.
When Coinbase Pro announced zcash support back in November 2018, it said that it would “support deposits from both transparent and shielded addresses, but only support withdrawals to transparent addresses. In the future, we’ll explore support for withdrawals to shielded addresses in locations where it complies with local laws.”
Users of Coinbase in other jurisdictions appear unaffected by the removal of zcash support at press time.
