Bitcoin hardware wallet TREZOR is ending its BitPay integration over what its CTO describes as “playing games” with its API.

In Twitter posts Thursday, Pavol Rusnak said that because BitPay could potentially rename the SegWit2x chain ‘BTC,’ Trezor would no longer display its tickers.

The hardware wallet had adopted a cautious approach to SegWit2x, while BitPay, along with fellow wallet Xapo, said it would potentially treat the 2x chain as ‘BTC’ should it gain sufficient support.

“We're replacing… BitPay exchange rates API in… TREZOR Web Wallet because they plan to play games with the BTC ticker. Can't tolerate this,” Rusak wrote.

The move comes as major exchange Kraken announced it was halting its BitGo implementation by the end of October. The payment provider’s CEO Mike Belshe is one of the foremost supporters of SegWit2x.

In an email to users, however, Kraken said its decision was “not in any way motivated by a concern over the quality of BitGo’s service.”

“We are simply moving Bitcoin (and tether) to an alternative system that provides similar security benefits with multi-party signing. Migrating Bitcoin to the alternative wallet system will help make our infrastructure more unified and easier to manage,” it explained.

Rusnak jumped on the news to taunt Belshe about his 2x advocacy as an increasing number of Bitcoin businesses come out in public condemnation of the hard fork attempt.

This week has seen opposition come from the Hong Kong community, with ANXPRO rejecting 2x ahead of a group of local businesses and private entities forming the Hong Kong Bitcoin Meetup.
