Crypto exchange Kraken has launched a new Bitcoin staking product through a protocol integration with Babylon Labs. In a Thursday announcement, Kraken said it has partnered with the Bitcoin BTC staking protocol Babylon. The integration allows the exchange’s users to earn interest on their Bitcoin holdings without the need for bridging, wrapping or lending. Kraken customers can use the service starting today by staking their Bitcoin without interacting with off-exchange wallets. The Bitcoin is locked in a vault on the Bitcoin blockchain and delegated to secure proof-of-stake (PoS) networks through the Babylon protocol. The rewards are not paid in Bitcoin; users earn Babylon’s BABY token. The BABY price has increased by nearly 5% since the announcement, according to CoinMarketCap.
