Lido on Solana has effectively closed down.
If you haven't unstaked, you can visit stsol.nansen.ai - a new dedicated web interface developed by Nansen - to unstake your stSOL.
The unstaking process is straightforward:
Head over to stsol.nansen.ai.
Connect your wallet. It is recommended to move your stSOL to a wallet like Phantom for easier withdrawal of inactive stakes at Step 4.
Submit the amount to unstake. Your stake will take 2-3 days to fully deactivate after initiating the unstake process.
Withdraw the inactive stake. Once deactivation is complete, use your wallet (e.g., Phantom) to withdraw your stake.
