Sablier Labs Enters Maintenance Mode and Pauses Development Until June 2028
Sablier Labs, the company behind token-streaming and vesting infrastructure, has halted active product development and moved into maintenance mode through June 2028, according to co-founder and CEO Paul Berg. The company said existing streams, vesting plans, and airdrops will continue to operate because Sablier’s smart contracts are deployed onchain and do not depend on the company remaining in business. Starting July 13, 2026, the official interface stopped accepting new vesting streams and airdrops with end dates beyond June 2028, and it no longer allows open-ended payment streams. Berg linked the decision to a sharp drop in usage and revenue in the first quarter of 2026, even though the company shipped more features than in any prior quarter. He cited delayed token launches as crypto markets weakened and lower barriers for rivals as AI-assisted coding made replication cheaper. Sablier also moved up the license conversion for its main EVM smart contracts, switching immediately from Business Source License 1.1 to GPL on July 13, 2026, instead of waiting until July 1, 2029. The company said more than 345,000 Ethereum addresses have used the protocol across over 837,000 transactions and more than 547,000 vesting plans, airdrop claims, and payment streams on 30-plus EVM chains and Solana.
