Starknet posted on X that STRK staking has been launched on Starknet Sepolia. In this testnet phase, staking requirements allow more participants to stress test their staking contracts: - Minimum staking amount: 1 STRK (20,000 STRK for mainnet); Unlocking time: 5 minutes (21 days on mainnet). If the testing phase goes smoothly, the STRK pledge will go live on the mainnet in a few weeks.
