Fact Check
The official Starknet X (formerly Twitter) account, a primary source, explicitly states that BTC staking is 'going live on Mainnet on September 30'. This is corroborated by a recent news article from Phemex. While some older official Starknet documentation and blog posts mention a 2025 timeline for BTC staking, the social media announcement represents the most current information and likely reflects an updated or accelerated plan. Other evidence refers to the separate launch of STRK token staking, which is not the subject of the statement.

Summary

StarkNet has officially integrated Bitcoin into its staking mechanism, with rewards set to start on September 30, 2025. BTC will contribute 25% to the network’s staking power, alongside STRK at 75%. Supported BTC wrappers at launch include WBTC, LBTC, tBTC, and SolvBTC. The unstaking period has been reduced to 7 days, offering more flexibility. This move follows the ratification of StarkNet Improvement Proposal 31 (SNIP-31), which enabled BTC staking and established governance rules. Bitcoin staking on StarkNet reflects the broader rise of BTCfi, where Bitcoin plays a larger role in DeFi.
