Superfluid Review 2026: Per-Second Money Streaming

Superfluid is a protocol for streaming money onchain. Rather than sending payments in chunks, a sender opens a stream and the recipient's balance increases every second. The project describes it as programmable cashflows for subscriptions, salaries, rewards and other recurring value.

DefiLlama lists it under Payments, on ten chains including Ethereum, Base, Arbitrum, Optimism and Polygon, with about $5.4 million in TVL and a listing date of October 2021. The homepage claims over $1.7 billion streamed to more than 1.31 million recipients. These figures come from the project itself.

The Superfluid Foundation runs the project, and its SUP token is tied to rewards and governance. The protocol is aimed at both end users and app developers who want to build streaming features into DeFi, SocialFi and gaming products.

Superfluid lets a sender set a flow rate for a token, and the recipient's balance grows every second without a transaction for each payment. The sender typically locks a buffer deposit so the stream can be covered, and balances are calculated continuously from the flow rate and time. Public sources describe this as continuous settlement with per-second netting.

Because streams net against each other, an address receiving and sending streams only settles the difference. The project says this gives high capital efficiency. Developers can build on top of streams to split income and redistribute yield or rewards to many recipients.

SUP is the ecosystem token. The homepage says users earn it by using apps in the ecosystem rewards campaign, and that it can be used for governance via a forum and voting.

The project does not publish a fee schedule for the protocol or its apps. Users should expect to pay normal network gas on whichever chain they use, and Ethereum mainnet will usually cost more than the layer-2 networks.

Any app-level charges would be shown in the Superfluid app, the docs, or the third-party apps built on the protocol. Check these before opening a stream.

DefiLlama lists two audits for Superfluid, but the project does not name the auditors, dates or findings. Check the audit reports in the official docs before relying on them. Streams run through smart contracts, so bugs, token-specific issues or running out of balance are risks users carry.

The project does not mention any hacks or incidents, and they do not describe the Foundation's regulatory status. This review is research-based and does not involve hands-on testing. Treat the data as a snapshot and verify current information in the official docs and governance forum.

Superfluid fits DAOs and crypto-native organisations that pay contributors on a recurring basis, developers building reward or subscription features, and users who like automated flows such as DCA. People who only want a simple one-off transfer will likely find a standard wallet send easier.
