Wu said he learned that the on-chain streaming payments protocol Sablier Labs has announced that it will stop active product development and enter maintenance mode until June 2028. Existing streams, vesting plans, and airdrops are not affected. The smart contracts will continue to run on-chain, and the official interface is planned to be open-sourced in the future and maintained by the community. Founder Paul Razvan Berg said that in the first quarter of 2026, usage and revenue fell sharply. Customers delayed rollouts due to worsening market conditions, and AI-assisted programming has also significantly reduced the cost of copying similar products. The team ultimately determined that although there is demand for on-chain token distribution and streaming payments, the market size is not large enough to support the company.
