Streamflow vs Superfluid: Which Payment Model Fits? (2026)

Streamflow and Superfluid both automate token payments, but they solve different problems. Streamflow is organized around distribution events and schedules: teams can set up vesting, batch airdrops, claim portals, staking rewards and token locks. Its SDK also supports programmable transfers, while white-label portals let projects use a branded front end.

Superfluid is organized around ongoing flows. Rather than sending payments in periodic lump sums, it moves tokens continuously, with balances updating every second. The protocol supports recurring payments such as salaries, grants and subscriptions, as well as income splitting and redistribution. This model can suit teams that need cashflows to run continuously, but it may take more explanation for users unfamiliar with streams and deposits.

Both protocols leave fee details unclear. Streamflow does not state fee amounts, and its custom or white-label work has no published prices. Its fee information is not sufficient to compare the cost of setting up a vesting contract, airdrop or other product. Confirm the full charge in the app before creating a distribution.

Superfluid does not publish a fee schedule for the protocol or its apps. Users should also budget for network gas on the chain they choose; gas costs vary by network, and Ethereum mainnet will usually cost more than layer-2 networks. Apps built on Superfluid may have their own charges, so check the relevant app before opening a stream. With neither protocol, the information here establishes a clear lower-cost choice. Compare the actual charges for the specific product and network you plan to use.

Both protocols have two audits listed, but that alone does not establish that using them is risk-free. Streamflow says distributions use audited smart contracts, but auditor names and report details are not published. Its vesting and airdrop contracts can hold real token balances, so contract bugs could put funds at risk. The project describes its design as non-custodial, with tokens in on-chain contracts rather than held by a company.

Superfluid also has two audits listed, but auditor names, dates and scope are not published. Streams depend on smart contracts, and users face risks from bugs, token-specific issues or insufficient balance to sustain a stream. For either protocol, review audit reports before committing significant value and understand how the relevant contract works. The STREAM and SUP tokens also carry market risk; neither audit count removes that risk.

Streamflow lists six chains, including Solana, Ethereum, Polygon and BNB Chain, but its chain support is inconsistent: its homepage FAQ says all services run on Solana. Confirm that the exact product you need is available on your intended network before planning a distribution. Its listed ease-of-use score is 7.5, and its features are aimed at teams managing token programs rather than only simple transfers.

Superfluid lists ten networks, including Ethereum, Base, Arbitrum, Optimism and Polygon. This gives builders more listed network choices, but users need to select the correct chain and manage gas on it. Its ease-of-use score is 6.5, and newcomers may need to learn how open streams, balances and deposits work. Both offer builder-oriented capabilities, but Streamflow's toolkit centers on distribution setup while Superfluid's centers on continuous cashflows.

Choose Streamflow if your main job is distributing tokens according to a schedule or to many recipients. Its combination of vesting, airdrops, staking, locks, SDK integrations and branded portals makes it the more direct match for project teams running token programs. Verify chain support for your specific use case, especially if you are not building on Solana, and check all applicable charges before creating contracts.

Choose Superfluid if you need payments to flow continuously rather than arrive as scheduled transfers. Its per-second model and ten listed networks suit builders and crypto-native teams working on salaries, grants, subscriptions or real-time splits. Expect a learning curve, and check network gas and any app-level fees before opening a stream. Neither is the clear choice for lower fees: fee schedules are not published for either.
