What is Sablier Labs?

Sablier is an onchain token distribution protocol for continuous streaming, vesting schedules, payroll, and token airdrops. Launched in 2019, it lets senders deposit ERC-20 assets into smart contracts that release funds to recipients by the second. More than 345,000 users have completed over 838,000 transactions across its contracts.

Organization and backing

Sablier Labs develops the protocol. Backers include Fenbushi Capital, Evan Van Ness, Lito Coen, and Daniel Bar. After expanding across multiple blockchain ecosystems, the team announced in July 2026 that Sablier had entered maintenance mode until June 2028, after which the project plans to wind down operations.

How the protocol works

Sablier runs non-custodial smart contracts on more than 25 EVM mainnets, including Ethereum, Arbitrum, Base, Optimism, and Polygon. Senders deposit supported ERC-20 tokens into contracts such as Sablier Lockup, which distributes tokens dynamically, linearly, or in tranches according to predetermined cliffs and schedules. Sablier Flow provides open-ended payment streams for continuous payroll. The Sablier Airdrops tool executes batch distributions using Merkle trees, and users can claim instantly or enter linear vesting streams. Recipients can withdraw vested amounts directly at any point without manual intervention from the sender.

Fees and access

Interacting with Sablier requires network gas fees alongside interface fees for specific contract interactions. The web interface applies a flat $0.99 fee, paid in the network's native gas token, per stream withdrawal on Lockup v2.0+ and Flow v1.1+. For Merkle airdrops, creators can sponsor claims starting at $1.99 per recipient, or recipients can pay variable claiming fees directly. Anyone with an EVM-compatible wallet or Safe multisig can use the open-source contracts and public interface.

Audits and operational limitations

Sablier's smart contract suites have undergone multiple independent security audits and public audit contests. Sablier shut down its Solana web interface in June 2026, leaving only the underlying onchain programs active. With the protocol operating in maintenance mode until an eventual June 2028 shutdown, teams building long-term distribution workflows face planned end-of-life constraints.

Sablier Labs has provided onchain token streaming and distribution infrastructure since 2019. Its smart contracts manage continuous vesting, payroll, and token distributions, handling more than 838,000 transactions across 345,000 users. Deployments span 25 EVM mainnets including Ethereum, Arbitrum, Base, and Polygon, alongside smart contract programs on Solana. The protocol supports linear or dynamic lockup schedules, as well as open-ended streaming flows and Merkle-based airdrop campaigns.

The protocol offers flexible architectures for automated distributions. Senders can stream tokens per second or add cliffs without managing recurring manual transactions. For developers and automated systems, Sablier maintains agent skill toolkits and CLI packages like npx skills that let AI agents and scripts deploy distributions directly. Interface pricing is transparent: streams built on Lockup v2.0 and Flow v1.1 incur a flat $0.99 withdrawal fee paid in native gas tokens, while Merkle airdrops charge volume-tiered fees starting at $1.99 per claim, which creators can sponsor upfront.

Operational longevity is the primary consideration for potential users. In July 2026, Sablier announced it entered maintenance mode and will wind down in June 2028. The Solana web interface shut down in June 2026, and the official Discord was shifted to read-only mode in May 2026 due to moderation overhead. While the underlying smart contracts remain deployed and verifiable onchain on block explorers, teams must account for the shrinking operational footprint.

Backed by investors including Fenbushi Capital, Evan Van Ness, Lito Coen, and Daniel Bar, Sablier offers a proven track record dating back to 2019 for organizations seeking automated per-second vesting schedules on EVM networks.

FAQ

What is Sablier?

Sablier is an onchain token distribution protocol used for vesting, payroll, continuous grants, and airdrops. It distributes tokens by the second via smart contracts across EVM networks and Solana.

What fees does Sablier charge?

The Sablier interface charges a flat $0.99 fee in the native gas token for stream withdrawals on Lockup v2.0 and Flow v1.1 contracts. Airdrop claim fees start at $1.99 per claim, which campaign creators can sponsor upfront.

Which chains does Sablier support?

Sablier contracts are deployed on 25 EVM mainnets, including Ethereum, Arbitrum, Base, Polygon, Linea, and Avalanche, as well as Solana. Certain chains are accessible directly onchain rather than through the primary web interface.

Where are tokens held during a Sablier stream?

Tokens are held non-custodially inside Sablier smart contracts deployed on each respective network. Recipients can withdraw vested portions directly through the interface or via contract calls on block explorers.

Does Sablier have an official token?

No, Sablier does not have its own native token. Protocol operations and interface fees are settled using the native gas token of the corresponding chain or the streamed ERC-20 assets.

Can senders cancel a Sablier stream?

Yes, creators can cancel eligible streams in Sablier Lockup or void streams in Sablier Flow. When a stream is canceled, unvested tokens are refunded to the sender while the recipient retains already vested tokens.

We've made the difficult decision to enter Maintenance Mode until June 2028, after which we will wind down.

1/ We've made the difficult decision to fully shut down the official Sablier UI on Solana.

https://t.co/8xS79VOay3 goes offline on June 30, 2026.

The SolSab programs will remain deployed onchain. Here's what you need to do before then. 🧵

PSA: our Discord will be entering read-only mode on May 1.

The primary reason for this decision is the overwhelming number of scammers we've had to deal with on the server.

Despite our moderation efforts, it has become increasingly difficult to keep the community safe from bad actors impersonating our team and targeting our users.

Going forward, you can still reach us through the following channels:

- Email: for direct support inquiries ([email protected])

Sablier on Solana is entering maintenance mode.

Starting today, it will no longer be possible to create new streams and airdrops on https://t.co/8xS79VNCIv

Existing streams and airdrop campaigns remain fully functional — recipients can still withdraw and claim as normal.

We just launched a new Bob pool with a $10,000 target price 🚀

As a reminder, Bob is our product that allows for price-gated lockups: tokens unlock only when a specified price target is reached.
