Fact Check
The official Sablier X post confirms entry into maintenance mode until a June 2028 wind-down. Cryptobriefing, PANews, and Phemex all independently corroborate the same details: the Q1 2026 usage and revenue drop cited by CEO Paul Razvan Berg, continuation of existing token streams via autonomous on-chain contracts, and the early relicensing of core smart contracts from BUSL to GPL. Every specific element of the claim is directly supported by the primary source and multiple corroborating reports.
Summary

Sablier Labs said it has stopped active product development and entered maintenance mode until June 2028 after a sharp fall in usage and revenue in Q1 2026. Co-founder and CEO Paul Berg said existing streams, vesting plans and airdrops are unaffected because the protocol’s smart contracts are onchain and permissionless, even if the company is no longer operating. Starting July 13, 2026, Sablier’s official interface stopped accepting new vesting streams and airdrops with end dates beyond June 2028 and blocked open-ended payment streams entirely. Berg said deteriorating crypto markets led customers to delay token launches, while AI-assisted coding made it cheaper for rivals to copy Sablier’s products, undermining the economics of the business. Sablier also accelerated the license change on its primary EVM smart contracts, shifting from Business Source License 1.1 to GPL effective July 13, 2026 instead of July 1, 2029, allowing unrestricted forking and deployment. The company said more than 345,000 Ethereum addresses have interacted with the protocol across over 837,000 transactions and more than 547,000 vesting plans, airdrop claims and payment streams on more than 30 EVM chains plus Solana, with zero security incidents involving user funds.
