Sablier Labs Stops Product Development and Puts Business Into Maintenance Mode Until 2028

Maintenance mode through 2028

The company said its existing streams, vesting plans and airdrops will continue unaffected. Berg said that is because Sablier’s smart contracts are on-chain and permissionless, meaning they do not rely on the company remaining in business in order to function.

The maintenance period is set to last until June 2028. During that time, Sablier is no longer pursuing active product development.

New restrictions on the official interface

Sablier also changed what users can set up through its official interface starting July 13, 2026. From that date, the interface no longer accepts new vesting streams or airdrops with end dates later than June 2028. It also blocks open-ended payment streams entirely.

The changes apply to the front-end interface rather than to the underlying contracts, which remain on-chain. Existing arrangements are not being shut down under the new policy.

Why the company changed course

Berg attributed the decision to a steep drop in usage and revenue during the first quarter of 2026. He said the decline came even though Sablier shipped more features in that quarter than at any previous time.

According to Berg, two factors drove the downturn. One was that customers delayed token launches as crypto market conditions worsened. The other was that AI-assisted coding lowered the cost for rivals to copy Sablier’s products.

Berg argued that these trends undermined the economics of the business. In his view, onchain token distribution and money streaming do not represent a venture-scale opportunity, and the market is not large enough to justify continued development.

Contracts moved to GPL ahead of schedule

Alongside the operational shift, Sablier accelerated the licensing change for its main EVM smart contracts. The contracts had been set to convert from Business Source License 1.1 to the GPL on July 1, 2029. Instead, the company brought that conversion forward to July 13, 2026, making the switch effective immediately.

Sablier said the change allows the community to fork, modify and deploy the contracts without restriction. That means the core infrastructure can continue to be used and adapted even as the company itself steps back from building new products.

The announcement marks a significant retreat by a company that focused on crypto-native payroll, vesting and token distribution tools. While Sablier says its infrastructure will remain live because of its on-chain design, the decision reflects pressure on niche crypto software businesses facing weaker demand and faster product imitation.
