Superfluid is a money-streaming protocol for real-time, on-chain cashflows, enabling continuous "payments by the second" to any wallet address across EVM networks. Built by Superfluid Labs, the protocol powers salaries, subscriptions, rewards, airdrops, vesting, and incentive distributions as programmable token streams and distribution pools. Developers integrate via first-party TypeScript SDKs (@superfluid-finance/sdk-core, sdk-redux), the on-chain smart contracts (@superfluid-finance/ethereum-contracts), an embeddable checkout Widget, and a public GraphQL Subgraph API served through The Graph for querying streams, pools, accounts, and token statistics. The protocol has streamed over $1.6B to 1.27M recipients across DeFi, SocialFi, and gaming use cases.
