What Sablier does
Sablier, operated by UK-incorporated Sablier Labs Ltd, builds on-chain token streaming infrastructure used by DAOs, crypto-native businesses, and token-launching projects for vesting, payroll, airdrops, and grant distribution. Founded in 2019 by Paul Razvan Berg, it is the first protocol of its kind in web3 and has processed 781,000+ transactions across 344,000+ users without a security incident, supported by audits from Cantina, CodeHawks, and five other firms. The core product line includes Sablier Lockup (closed-ended streams with linear, cliff, exponential, and tranched vesting curves wrapped in ERC-721 NFTs), Sablier Flow (open-ended streaming for recurring payments like payroll launched in December 2024), Sablier Airdrops/Airstreams (gas-efficient Merkle-based vested airdrops for up to 50,000 recipients), Sablier Bobs (Chainlink price-gated timelocks), and a self-serve web app (app.sablier.com) deployed across 24+ EVM chains and historically Solana.
The underlying technology is a set of immutable, open-source smart contracts managed in an EVM monorepo, with a REST/Merkle API and npm-distributed Sablier Skills and Agent Skills that enable AI agents to execute vesting, airdrop, and payroll workflows. The protocol reaches users through a product-led, community-led, and API-first go-to-market — wallet-based onboarding without signup, Discord/GitHub/Twitter community engagement, and native integration with Safe{Wallet} multisig and Chainlink oracles. Marquee users include Uniswap, Ethena, Compound, Maple, Immutable, Fjord, Arbitrum DAO, Shapeshift, Nouns DAO, Parifi, TokenSight, Aragon, and Reflexer.
Sablier's revenue mechanics consist of $0.99 per stream withdrawal fee (Lockup v2.0+ and Flow v1.1+), up to $1.99 per airdrop claim fee (Airdrops v1.3+), yield and flat fees on Bob vaults, and pass-through gas fees that go entirely to validators. The company has raised $5M cumulatively — a $500K pre-seed in 2022 from Starbloom Capital, Safe Ecosystem Foundation, F.actor, and angels, followed by a $4.5M seed in March 2024 led by A Capital and Fenbushi Capital with a16z Crypto Startup Accelerator (CSX) participation — and operates with a 1–10 person remote team, indicating a pre-scale commercial phase ahead of its stealth Sablier V3 platform.

Revenue model
- Stream Withdrawal Fees: Flat fee charged each time a user withdraws from a stream. Fee is $0.99 in the native gas token (e.g., ETH on Ethereum, POL on Polygon). Applies to Lockup v2.0+ and Flow v1.1+ streams.
- Airdrop Claim Fees: Dynamic fee charged when claiming airdrops. Fee is up to $1.99 in the gas token. Applies to Airdrops v1.3+.
- Bob Vault Fees: Yield fee on positive yield generated by Lido adapter (configurable percentage). Flat fee in native gas token on vaults without adapter.
- Gas Fee Pass-through: Gas fees charged to users for blockchain transactions (create, cancel, transfer, withdraw). 100% goes to blockchain validators; Sablier does not take a cut.

- Sablier Protocol (Lockup) Core on-chain closed-ended token distribution infrastructure supporting customizable vesting schedules (linear, cliff, exponential, step unlock, tranched). Every stream is wrapped as an ERC-721 NFT owned by the recipient. Used by DAOs, web3 organizations, and crypto startups for vesting, grants, and time-locked distributions on 24+ EVM chains.
- Sablier Flow Open-ended token streaming product designed for recurring payments like payroll, with isolated per-pair balances, adjustable rates on the fly, pause/resume functionality, and deposits from any address. Built for crypto-native teams paying contributors continuously.
- Sablier Airdrops (Airstreams) End-to-end vested airdrop solution supporting up to 50,000 recipients via Merkle tree distribution with gas-efficient batch claims. Recipients claim tokens that then vest over time, preventing day-one dumps and aligning community participation.

Sablier competitors and assessment
Company assessmentDirect peers
- Superfluid: Direct competitor offering real-time token streaming and payroll on EVM chains. Comparable product (continuous payment streams) for DAOs and crypto-native teams, competing head-to-head with Sablier Lockup and Flow.
- Streamflow Finance: Solana-native token vesting and streaming protocol with vested airdrops and payroll. Directly comparable on vesting, airdrops, and recurring payments — especially relevant given Sablier's Solana (SolSab) operations.
- LlamaPay: Early mover in on-chain streaming payroll for DAOs and crypto companies. Competes with Sablier Flow on continuous token payments, particularly on EVM chains like Ethereum and BNB.
- Unlock Protocol: On-chain token vesting and lockup protocol for DAOs and Web3 teams. Comparable use case (timelocked distributions) and similar customer base to Sablier Lockup.
Emerging players
- Aragon: DAO framework and governance infrastructure with token distribution capabilities. Listed as a Sablier customer; competes at the DAO infrastructure layer where vesting and grants intersect with governance.
- Juicebox: DAO treasury and fundraising protocol. Adjacent to Sablier in the DAO tooling stack — both serve token-launching projects and DAOs managing token distribution, though Juicebox focuses on fundraising mechanics.
Others
- Safe (Gnosis Safe): Multi-sig wallet standard used by most DAOs and treasury teams. Both an investor in Sablier and a deep integration partner (Sablier runs as a native Safe app), making it the primary distribution surface for Sablier's enterprise users.
- CoW Protocol / Symbiotic: DeFi protocols using Sablier for token vesting and emissions. Not a direct competitor but a representative class of enterprise DeFi customers that anchor Sablier's recurring usage and TVL footprint.
- Pyth Network: Oracle network comparable to Chainlink. Like Chainlink, Pyth could underpin price-gated streams (Sablier Bobs) and adjacent DeFi primitives — an alternative data-source peer in the onchain financial infrastructure stack.
- Hyperlane: Cross-chain interoperability infrastructure for EVM and non-EVM chains. Adjacent enabling infrastructure that, like Sablier, serves multi-chain token distribution use cases for protocols operating across heterogeneous chains.
