Kraken just made it easier for Bitcoin holders to stop letting their BTC sit around doing nothing. The exchange launched its Bitcoin Vault in May 2026, giving users access to onchain lending yields directly from their Kraken accounts.
The product offers an initial annual percentage yield of 2.0%, which becomes variable over time. It’s part of Kraken’s broader DeFi Earn suite, which the exchange first rolled out in January 2026 with USDC-focused vaults.
How the Bitcoin Vault actually works
When a user allocates BTC to the vault, the Bitcoin gets wrapped as kBTC and deployed into onchain lending strategies via a non-custodial embedded wallet on the Ink network. Your Bitcoin gets converted into a tokenized version of itself, lent out through smart contracts, and you earn interest on it, all without leaving the Kraken interface.
The minimum allocation is remarkably low at 0.00006 BTC.
