Coinbase Prime and staking infrastructure provider Figment announced an expansion of their partnership to support institutional staking across a wider range of proof-of-stake networks. The collaboration now includes support for Solana, Cardano, Sui, Polkadot, Avalanche, and others, adding to the existing Ethereum staking service which has secured over $2 billion in assets since early 2024. The move provides institutional clients with more flexibility in choosing staking providers while keeping their assets in Coinbase Prime's secure custody environment. This integration allows clients to manage staking activities alongside trading and financing from a single platform, reinforcing Coinbase's commitment to validator diversity and decentralization. The announcement comes as new spot Solana staking ETFs are set to launch in the U.S.
