Sablier Labs is done building. The token streaming protocol announced on July 13, 2026, that it is entering maintenance mode, with a full wind-down planned for June 2028. New development stops now. Existing streams keep running.
The decision came from co-founder and CEO Paul Razvan Berg, who cited a sharp drop in usage and revenue during Q1 2026 as the catalyst. Two culprits: delayed token launches that dried up demand, and a wave of AI-assisted competitors who could build similar tools faster and cheaper than ever before.
What maintenance mode actually means
Here is the practical breakdown. Sablier’s smart contracts are non-upgradeable and permissionless, which means no one can turn them off, including Sablier. Anyone with an active stream, vesting plan, or airdrop claim will continue to receive their funds exactly as scheduled.
What does stop: the official interface will no longer accept new vesting streams or airdrops with end dates beyond June 2028. Open-ended payment streams are also blocked. In English: you can collect what you are owed, but you cannot start anything new through Sablier’s front end.
