Fluidity

Fluidity Money is a decentralized finance (DeFi) protocol that turns idle crypto into "Fluid Assets" (fAssets) — ERC-20-compatible wrapped tokens on Ethereum/Arbitrum and SPL tokens on Solana that pay instant, probabilistic rewards every time they are transferred (the Transfer Reward Function). Yield is sourced from lending protocols such as Compound and AAVE on Ethereum and Solend on Solana, and distributed through "utility mining." Fluidity exposes a public GraphQL API over its webapp and landing-page data, publishes EVM ABIs and Solana program/account structures for on-chain integration, and is governed by the $FLY token. Fluidity Labs sunsetted active protocol development on 2026-04-01 to focus on the Superposition ecosystem; docs, status page, and on-chain contracts remain live.

Fluidity publishes 1 API on the APIs.io network. Tagged areas include Company, Crypto Web3, DeFi, GraphQL, and Ethereum.

Fluidity’s developer surface includes documentation, API reference, getting-started guide, engineering blog, support, and 13 more developer resources.
