Bloom

Bloom is a wallet interface designed to help AI agents interact with cryptocurrency and onchain applications safely. Rather than exposing private keys to an agent, Bloom keeps keys encrypted on the user’s device and lets the agent prepare and carry out transactions within permissions the user has approved. Its Sealed Approvals allow users to set limits on spending, actions, recipients, and duration; requests outside those boundaries require further approval.

Built for filesystem-based agents, Bloom supports tools including Claude, Codex, Cursor, and Hermes. It offers access to multiple networks, including Ethereum, Solana, Base, Arbitrum, and Polygon, and connects with applications such as Hyperliquid, Polymarket, and Enso. Users can direct agents to trade, swap, send funds, bridge assets, check activity, or perform recurring tasks such as dollar-cost averaging and portfolio rebalancing.

Bloom is available as open-source alpha software and is free during the alpha period, with standard network fees still applying. The product is under active development and has not yet been audited, so Bloom recommends starting with small amounts.
