Superfluid (SUP): What It Is, Uses and Risks

Superfluid is an onchain payments protocol that lets tokens move continuously rather than only in one-off transactions. It is designed for programmable cashflows, including payroll, grants, subscriptions, rewards and vault payouts. The project also describes uses in agentic commerce, where software agents may make or receive payments.

Superfluid is aimed at DAOs, developers and people using apps built around token streaming. Its protocol provides smart-contract tools for creating and managing these streams. The protocol’s purpose is distinct from the purpose of its token: a project can support a working product without every token automatically being required to use it. The information available here does not establish a specific required role for SUP, such as paying protocol fees or governing protocol changes.

A Superfluid stream represents an ongoing payment relationship. Instead of sending a recipient the full amount in a single transaction, a sender sets up a flow that transfers tokens over time. This can suit recurring payments such as a grant or subscription, or other arrangements where recipients should receive funds continuously.

The protocol is designed to make these cashflows programmable and composable with onchain applications. That can reduce the need to process each recurring payment as a separate manual transfer, but streams still rely on smart contracts and the conditions set when they are created. Users should check the stream’s terms, token, rate and cancellation rules before sending funds. Superfluid describes its protocol as operating across ten chains, while SUP itself is listed as issued on Base and Ethereum. These are separate facts: a protocol’s availability on a network does not mean its token is issued there.

SUP is the project’s token, but the public information available here do not specify exactly what holders can do with it. In particular, they do not confirm that SUP is required to create streams, pay fees, vote on governance proposals, stake or earn protocol rewards. Do not assume any of those uses based only on the protocol’s payment features; check the project’s current documentation for confirmed token functions.

The stated total supply is 1 billion SUP, with about 412.9 million circulating as of 2026-11-05. No maximum supply is listed separately. These figures describe different supply measures: circulating supply is the portion reported as available in the market, while total supply includes tokens that may not be circulating. Supply figures can change as tokens enter circulation, so treat them as a dated snapshot rather than a guarantee of future availability.

SUP is listed as issued on Base and Ethereum. The project’s streaming protocol is described as available across ten chains, but the information here does not name all of those networks or establish that SUP is available on each one. Before receiving or sending SUP, confirm the network and token contract through Superfluid’s official channels. A token with the same name or ticker on another network may not be the same asset.

As a market snapshot, SUP was about $0.00355, with a market capitalization of roughly $1.5 million, as of 2026-11-05. Prices, market capitalization and circulating supply can change quickly, and market figures may differ between services. A small market capitalization or reported trading volume can also mean fewer buyers and sellers are available at a given time. These figures are descriptive only; they do not indicate what SUP may be worth later.

SUP carries the risks common to crypto assets, including sharp price changes, limited liquidity, loss of access and errors when sending tokens. A stream adds smart-contract and configuration risks: an incorrect recipient, token, rate or duration can have costly consequences, and a contract flaw could affect funds. The token’s specific role is not confirmed here, so its value should not be assumed to come from guaranteed fees, rewards or governance rights.

For self-custody, use a wallet that supports the network holding your SUP, protect its recovery phrase offline, and never share that phrase or sign a transaction you do not understand. Check the network and contract address against official project information before transferring tokens; do not rely on a ticker alone. A hardware wallet can reduce exposure of signing keys to an internet-connected device, but it cannot prevent every mistake or smart-contract loss. If you use a custodial service, review its security and withdrawal terms.
