Our verdict on Kraken Bitcoin
Kraken Bitcoin is for people who want Bitcoin-linked value to use in DeFi on Ethereum, OP Mainnet and other ecosystems. Its main appeal is the stated full backing and exchangeability of kBTC. The main caveat is that the product description leaves important questions unanswered: it does not detail reserve verification, custody, redemption steps, fees or the full list of supported networks. Check those details before relying on kBTC for transfers or DeFi activity.
