Starknet has officially launched its Bitcoin staking integration, enabling BTC holders to participate in network consensus and earn rewards starting September 30. The upgrade, which went live today, follows the community ratification of StarkNet Improvement Proposal 31 (SNIP-31) on August 21, approved by 93% of voters.
Under the new system, Bitcoin contributes 25% of the network's staking power, while Starknet's native token STRK accounts for the remaining 75%. Supported BTC wrappers at launch include WBTC, LBTC, tBTC, and SolvBTC, with additional wrappers possible through governance. The unstaking period has been reduced from 21 days to 7 days, providing greater flexibility for stakers.
Validators can now deploy BTC delegation pools immediately, and builders can begin integrating the feature. This development reflects the growing trend of BTCfi, where Bitcoin is increasingly used in DeFi for earning rewards, governance participation, and cross-chain applications beyond simple holding or trading.
