Streamflow fills a critical operational gap in Web3 projects: how do you automate token vesting, pay contributors without trust, and distribute airdrops at scale? Traditional approaches involve manual treasury management, spreadsheets, wallet addresses, and multi-step transactions. Streamflow converts all of these operations into configurable on-chain streams and schedules — a smart contract handles the unlock logic, and beneficiaries claim what they’re owed at any time. Since launching on Solana, Streamflow expanded to EVM chains and became the default token distribution infrastructure for thousands of projects.
Core Products
The main product offerings are described below.
Token Vesting
How it works:
- Treasurer deposits tokens to a Streamflow vesting contract
- Configure: beneficiary address, cliff (initial locked period), unlock schedule (linear, cliff + linear, or custom)
- Beneficiary can claim tokens as they vest
- Contract enforces the schedule — no manual releases required
Common use cases:
- Team vesting: 1-year cliff, 3-year linear vest for founders/employees
- Investor vesting: 6-month cliff, 2-year linear vest for VCs
- Advisor vesting: Small allocations with monthly or quarterly unlocks
- DAO grants: Milestone-based or time-based token grants to contributors
Security: Vesting contract is a unilateral commitment — the treasure cannot change the schedule without beneficiary consent (configurable; some projects allow cancellation with a grace period).
Payroll Streaming
- Create a stream: 100 USDC per day to Alice’s wallet
- The stream drips continuously — every second, a tiny amount of USDC flows to Alice
- Alice can withdraw at any time against her accumulated stream
- No waiting for monthly payroll runs; money flows in real-time
Sablier model influence: Sablier on Ethereum pioneered payment streaming; Streamflow brought the model to Solana and extended it.
DAO treasury use:
DAOs use streaming payroll to pay contributors without trust — if the contributor stops working, the DAO can pause or cancel the stream. No need to claw back funds or trust the contributor to return unearned payment.
Airdrop Campaigns
Traditional airdrop pain points:
- Manually crafting thousands of transfer transactions
- Managing failed transactions (closed token accounts, wrong addresses)
- Paying for account creation (each recipient needs a token account)
- No vesting — recipients receive everything at once and dump
Streamflow airdrop:
- Upload CSV of (address, amount) pairs
- Select unlock schedule (optional: vest airdrop over time)
- Protocol handles all the creation, claims, and account management
- Recipients claim from Streamflow interface or protocol endpoint
Vested airdrops:
An important use case: instead of dumping tokens on day 1, projects vest airdrop allocations over 3-6 months. This distributes sell pressure and rewards longer-term holders. Streamflow makes this trivial to implement.
Supported Chains
Streamflow launched on Solana and expanded:
- Solana (primary; deepest protocol integration)
- Ethereum (EVM)
- BNB Chain
- Polygon
- Aptos
- Sui
Multi-chain deployment makes Streamflow useful for cross-chain projects.
Protocol Statistics
- Total value streamed: $1B+ (across all chains)
- Number of streams created: Hundreds of thousands
- Projects: 1,000+ projects used Streamflow for vesting, payroll, or airdrops
- Tokens supported: Any SPL token (Solana) or ERC-20 (EVM)
STREAM Token
Status: Streamflow has a STREAM token for protocol governance
Utility:
- Fee sharing from protocol revenue
- Governance over protocol parameters
- Some operational features access-gated by STREAM holdings

Use Cases for Projects
Typical Solana project workflow using Streamflow:
At token launch:
- Allocate team tokens → create Streamflow vesting schedule (1-year cliff + 3-year liner)
- Allocate investor tokens → create vesting per investment agreements
- Airdrop to community → use Streamflow airdrop tool with optional vesting
Ongoing:
- Pay contributors monthly → set up ongoing payroll streams
- DAO grants → stream USDC/token to grantees over 6-month project period
How to Use Streamflow
For project treasurers:
- Get USDC or tokens via
- Connect a Solana wallet (Phantom, Backpack) to app.streamflow.finance
- Create a vesting contract or stream using the dashboard UI
- Monitor streams — see projected and actual outflows
For recipients:
- Check if you have pending streams at app.streamflow.finance
- Connect your wallet → see available claims
- Claim tokens that have vested or streamed
Store tokens securely:
Social Media Sentiment
Streamflow is “boring but important” infrastructure — the kind of project that doesn’t generate memeable moments but is considered reliable by the Solana developer community. It’s nearly universally used for any serious Solana token launch for basic vesting contracts. The airdrop tool became genuinely popular in 2024 as projects adopted vested airdrops to reduce day-one sell pressure. The UX is praised compared to manual vesting contract deployment. The main criticism is that for complex vesting scenarios (milestone-based, conditional vesting), Streamflow is less flexible than custom implementations. The STREAM token has had limited attention relative to the protocol’s actual usage. Overall: a utility protocol that has earned its place in Solana’s development stack.
