According to Foresight News, Starknet announced that STRK staking has been launched on Starknet Sepolia. During the testnet phase, the staking requirements allow more participants to stress test their staking contracts. The minimum staking amount is 1 STRK (20,000 STRK on the mainnet), and the unlocking time is 5 minutes (21 days on the mainnet). If the test phase goes smoothly, STRK staking will be launched on the mainnet in a few weeks.
