Sablier Labs has stopped active product development and entered maintenance mode until June 2028, co-founder and CEO Paul Berg said on Monday.
Existing streams, vesting plans, and airdrops are not affected, Berg said, because “the Sablier smart contracts are onchain and permissionless” and do not rely on the company continuing to operate.
Interface changes took effect on July 13
According to Berg’s post, the official interface stopped accepting new vesting streams and airdrops with end dates beyond June 2028 starting July 13, 2026. It also blocked open-ended payment streams entirely.
Usage and revenue fell in Q1 2026
Berg said the move followed a sharp decline in usage and revenue in the first quarter of 2026, even though the company shipped its largest number of features ever during that period.
He pointed to two reasons: customers delayed token launches as crypto markets deteriorated, and AI-assisted coding reduced the cost for competitors to copy Sablier’s products.
“There isn't a venture-scale business in onchain token distribution/money streaming,” Berg wrote, adding that the market is not large enough to justify continued work.
Main EVM contracts now under GPL
Sablier also accelerated the license conversion for its primary EVM smart contracts. The switch from Business Source License 1.1 to the fully open GPL license was moved forward from July 1, 2029 to July 13, 2026, effective immediately.
The company said the change allows the community to fork, modify, and deploy the contracts without restriction.
Protocol activity and next steps
Sablier 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. The protocol has been deployed on more than 30 EVM chains as well as Solana.
Berg said the protocol recorded zero security incidents throughout its history of holding user funds.
He also said he plans to take a short break before returning to build in crypto.
