Wu Blockchain has learned that the on-chain streaming payment protocol Sablier Labs has announced it will cease active product development and enter maintenance mode until June 2028. Existing streams, vesting schedules, and airdrops will not be affected, and smart contracts will continue to operate on-chain. The official interface is planned to be open-sourced in the future and handed over to the community for maintenance. Founder Paul Razvan Berg stated that usage and revenue saw a significant decline in Q1 2026, as clients delayed launches due to market deterioration, and AI-assisted programming has drastically reduced the cost of replicating similar products. The team ultimately concluded that while there is demand for on-chain token distribution and streaming payments, the market size is insufficient to sustain the company. https://(wublock123.com)/news/sablier-halts-active-development-q1-usage-revenue-drop-clients-delay-launch-64556
