Altana
Altana provides a keystore layer that separates asset management from signer management, enabling multiple keys with different permissions to control a single wallet address. The platform lets users register session keys for AI agents with specific spending limits, contract allowlists, and expiration times, all enforced onchain. Altana is live on mainnet across BNB Chain, Ethereum, and Base, and powers sovereign agents in BNB Agent Studio.

Problem
Traditional crypto wallets are controlled by a single private key that signs every transaction across all chains, creating a single point of failure with no way to scope permissions. Users cannot safely delegate authority to AI agents or automation without either handing over full key control or relying on custodial third parties, limiting the practical deployment of autonomous agents in decentralized finance.
Solution
Altana provides a keystore layer that separates asset management from signer management, enabling multiple keys with different permissions to control a single wallet address. The platform lets users register session keys for AI agents with specific spending limits, contract allowlists, and expiration times, all enforced onchain rather than by a server or the agent itself. A public registry on Ethereum L1 stores all signing credentials, and L2 cache contracts verify keystore state locally using Merkle Patricia storage proofs, eliminating the need for bridges or oracles. Users can revoke agent access in one click, effective before the agent's next action, and anyone can verify an agent's authorization without an account. The system supports native recovery through backup keys and provides instant multichain presence for new L2s without repeat onboarding. Altana is live on mainnet across BNB Chain, Ethereum, and Base, and powers sovereign agents in BNB Agent Studio.
Target Audience
Primary users are Web3 developers, DeFi power users, and AI agent builders who need to deploy autonomous agents with secure, scoped, and revocable wallet permissions across multiple chains.
Features
- Smart Agentic Wallets: self-custodial accounts where the user holds the full key and the agent receives a scoped key with no third-party access
- Onchain permission enforcement: the wallet checks every action against user-set rules for location, amount, and duration, verifiable by anyone via the public explorer
- Keystore layer on Ethereum L1 with L2 cache contracts using Merkle Patricia storage proofs for trustless state verification
- Multiple signer support: phone passkeys, hardware wallets, and session keys with different policies attached to the same wallet address
- One-click revocation of agent access, effective before the agent's next action
- Global policy engine: spending limits, session keys, and approval workflows set once apply on every chain where the wallet exists
- SDK and MCP connectivity for any AI model, with no-code setup for permissions, visualization, and interaction with any open protocol
