BTC.com

BTC.com Wallet was a self-custodial Bitcoin wallet operated under the BTC.com brand by Bitmain. The wallet traced its origins to Blocktrail, a Dutch blockchain explorer and wallet startup founded in 2014. Bitmain acquired Blocktrail in July 2016 and rebranded the product under the BTC.com name, incorporating Blocktrail’s multi-signature HD wallet technology. Users held their own private keys, and wallet recovery relied on an encrypted backup PDF generated at setup combined with a user-set password.

The wallet supported Bitcoin (BTC) as its primary asset. Its self-custodial model was a key selling point: funds remained on-chain and were recoverable as long as the backup PDF and password were preserved.

BTC.com changed ownership in 2021. Following a corporate split between Bitmain’s co-founders, the BTC.com brand was transferred to BIT Mining Limited (NYSE: BTCM), a publicly listed company formerly known as 500.com. Under new ownership, BIT Mining refocused BTC.com on its mining pool and block explorer, and the consumer wallet was no longer maintained.

In early 2022, BTC.com announced the discontinuation of its wallet service, instructing users to withdraw their funds before April 15, 2022. The wallet platform was shut down on that date. The Blocktrail recovery tool was also permanently disabled, leaving users without an official recovery path if they had not already saved their backup PDF. The website at wallet.btc.com is no longer accessible.
