Token Streaming Protocol Suite

Sablier provides battle-tested smart contract infrastructure for continuous token distribution, enabling organizations to automate vesting, payroll, airdrops, and grants with sophisticated onchain logic. The protocol has operated for over 5 years without security incidents, audited by Cantina, Codehawks, and five other leading security firms.

Core Protocol Features

Token Vesting Automation: Customizable vesting schedules support linear distributions, cliff periods, monthly unlocks, discrete unlocks, timelocks, and fully custom curves designed through an interactive editor. Organizations can create any unlock schedule imaginable with set-and-forget automation for multi-year distributions.

Real-Time Payroll Streaming: By-the-second compensation streams enable employees to withdraw earned salary at any time, eliminating traditional payroll delays. The protocol supports flexible pay periods, recurring annual streams, and top-up balances for raises or bonuses.

Gas-Efficient Airdrop Infrastructure: Merkle tree technology enables distribution to 1 million+ recipients with minimal gas costs. Campaigns support instant or vested distribution, time-limited claim windows with automatic fund recovery, and eligibility verification tools.

Milestone-Based Grant Streaming: Funds stream continuously as work progresses, with cancellation rights if milestones aren't met. The system provides accountability through real-time streaming aligned with project delivery.

Smart Contract Capabilities

Advanced Token Mechanics: The protocol implements sophisticated custom logic including cancelable streams with fund recovery, bulk stream creation via CSV upload, Safe multisig integration for governance-controlled distributions, and immutable smart contracts that cannot be altered post-deployment.

Custom Distribution Curves: Organizations can design any unlock schedule through an interactive editor, add multiple tranches on demand, and configure complex vesting structures with cliff periods and custom timing.

Automated Streaming Logic: Once configured, all distributions run automatically without continued involvement. The protocol handles by-the-second calculations, withdrawal mechanics, and fund recovery for canceled streams.

Onchain Transparency: All vesting schedules, payment streams, and distribution logic are fully verifiable onchain, providing real-time tracking for both grantors and recipients.

Technical Implementation

Battle-Tested Security: Fully decentralized protocol operated for 5+ years without incidents, audited by Cantina, Codehawks, and five additional security firms, with immutable smart contracts that provide unchangeable guarantees once deployed.

Multi-Chain Support: The protocol operates across multiple EVM-compatible chains, enabling organizations to deploy vesting, payroll, airdrops, and grants on their preferred network.

Gas Optimization: Merkle tree implementations for airdrops, efficient streaming calculations, and optimized contract architecture minimize transaction costs for both deployers and recipients.

Flexible Integration: Ready-to-use APIs support custom frontends, automated distribution workflows, and integration with existing organizational infrastructure.

Target Use Cases

The protocol serves DAOs managing treasury distributions, Web3 startups handling team vesting and payroll, blockchain protocols launching token airdrops, and organizations distributing ecosystem grants. Notable users include Fluid, FOX, EXA, Fjord, SALD, ITP, Parifi, Maple Finance, Arbitrum DAO, Uniswap grants, ShapeShift DAO, Safe, and Reflexer.
