Starknet, Ethereum’s layer 2 solution, was announced on September 30, 2025 through an X account that activates Bitcoin Staking (BTC) on its main network.
This measure allows BTC holders to participate in network security and earn rewards using wrap assets (representing Bitcoin on another network, but not BTC) Like WBTC, LBTC, TBTC, SOLVBTCIt is detailed in a message posted on September 11th.
Through governance, users can add other tokens representing BTC in the StarkNet chain.
StarkNet is the second layer of Ethereum (L2), so its validation and proper system works just like the base network. In this sense, Starknet’s statement clarifies the system Assign a weight of 0.25 to BTC with a consensus mechanismwhich represents 25% of the decisive power, with the remaining 75% remaining in the hands of the token STRK.
Furthermore, the period of Staking (When to delete blocked coins) It will decrease from the 21st to the 7th. Provides agility to users and representatives.
To implement this update, Starknet has warned that it will be suspended for several hours from 10am on September 15th, with the aim of integrating new mechanisms.
After the update, validators and developers can implement BTC delegation groups and begin integration with the protocol. Rewards will begin on 30/09.

On the other hand, the move expands the potential obligations of other networks for Bitcoin holders. The launch is evidence of the potential that Cardano creator Charles Hoskinson described as a “sleeping giant” in the context of Bitcoin and defi. And he makes it clear that Cardano alone does not have an intention to promote decentralized finance in BTC.
