Sablier Flow Review 2026: Constant-Rate Token Streaming

Sablier Flow is a payments product from Sablier, which describes itself as infrastructure for onchain token distribution used by DAOs and businesses for vesting, payroll and airdrops. Flow focuses on one job: paying at a constant rate, with the sender topping up the balance over time.

DefiLlama lists it under Payments, with about $542,000 in total value locked and a 7-day change of -4.2%. It has been tracked since April 2025, runs on more than 25 networks, and has no native token. Two audits are listed.

The model suits teams that pay contributors or staff continuously rather than in lump sums. The main trade-off is that the sender carries the job of keeping the stream funded, and the project does not publish fee details on its main pages.

Flow is built around a rate rather than a schedule. The sender chooses a token amount per unit of time, and the recipient's claimable balance grows every second at that rate. The sender deposits tokens into the stream so there is something to pay out.

Because there is no fixed end date, the stream is open-ended. The sender tops up the balance over time to keep it running. If the balance is not refilled, the stream can only pay out what has been deposited. This is different from a vesting schedule, where the full amount is locked up front and released on a fixed timetable.

The recipient can withdraw what has accrued to their wallet. Everything runs in smart contracts on the chosen network, so the app is an interface and the funds are held by the contracts rather than by Sablier as a company.

The main pages do not publish a fee schedule for Flow. Users should expect to pay network gas on whichever chain they use, and any protocol-level charge would be shown in the app when creating or managing a stream.

One search snippet for a separate Sablier airdrop campaign shows a claim fee of $1.99, but that belongs to the airdrop product and should not be assumed to apply to Flow. Check the app's confirmation screen before signing.

DefiLlama lists two audits for the project, though scope, auditors and findings are not detailed in the sources reviewed. Funds sit in smart contracts rather than with a custodian, so the main risks are contract bugs, wrong recipient addresses and running a stream out of funds. Verify the network and contract in the app before depositing.

The project does not publish regulatory status or team details on the pages reviewed. Treasuries sending significant sums should do their own review of the audit reports and consider starting with a small test stream.

Flow suits DAOs, crypto-native companies and freelancers paid in tokens who want salary or budget payments to accrue second by second. It is less suited to anyone who needs a fixed vesting schedule with a locked total, or to users who want a protocol with a token and incentive programme.
