Superfluid (superfluid)

Protocol for real-time finance enabling continuous token streams (per-second payments), distributions, and composable Super Tokens.

Fact	Value
Category	Payments and streaming
Family	none
Namespace	`Superfluid` on ethereum, optimism, polygon, base, arbitrum
Chains	ethereum, optimism, polygon, base, arbitrum

What it offers

Flowrate is in tokens per second (int96) - e.g. 1e18 / (30 * 86400) for ~1 token/month
Uses Super Tokens - wrapped ERC-20s with streaming capability (wrap before streaming)
The CFAForwarder has one address on every chain; the Host’s address differs per chain
CFAForwarder is the simplified interface; host is the core protocol contract
Streams are continuous - balance updates every second without transactions
Sender must maintain sufficient Super Token balance; otherwise stream gets liquidated
userData allows passing arbitrary data for composability with other contracts

On Ethereum, Superfluid is a namespace: its contracts need no import.

function main() {
  // Ethereum's cfaForwarder, `0xcfA132E353cB4E398080B9700609bb008eceB125`.
  require(Superfluid.CFAForwarder != 0);
