Figment is a blockchain infrastructure provider that exposes developer-facing APIs for staking and reporting across multiple proof-of-stake networks. Based on its documentation, the product is designed for teams that want to embed staking actions (delegate, undelegate, withdraw, claim rewards, broadcast transactions) and portfolio/reward reporting into their own applications without building chain-specific transaction logic for every protocol.

Figment’s core surface area is its API reference, which is organized by protocol (for example Ethereum, Solana, NEAR, Cardano, Cosmos, Avalanche, Polkadot, Polygon, Sui, and others shown in the docs). The endpoints cover common staking workflows—building staking transactions, broadcasting them, checking transaction status, and retrieving rewards and reward rates. On Ethereum, the API includes validator lifecycle operations such as creating validators (including “Pectra validators”), broadcasting staking and exit messages, generating compound/withdrawal/consolidation transactions, and querying validator activity and summaries. Several ecosystems also show “Flows API” endpoints (for example stake/delegate flows for NEAR, Cardano, and Cosmos), which indicates a higher-level abstraction for common staking actions.

In addition to staking, Figment includes reporting features such as tracking addresses for reporting, generating statements, and a portfolio endpoint. Cardano support includes pool discovery and reward withdrawals, plus a dedicated “Broadcast Transaction (Fireblocks)” endpoint, which suggests compatibility with Fireblocks-based signing/broadcast flows for that chain.

To get started, developers typically review the protocol overview for the chain they need, implement authentication, then wire up the relevant staking endpoints (build transaction → broadcast → status) and reporting endpoints (track address → statements/portfolio). Figment maintains a public GitHub organization, and its API reference and changelog are available in the documentation.
