AI Blockchain Key Manager

Autonomous key lifecycle management for wallets, smart contracts, and validators. Generate, rotate, retire — without losing access to chain state.

Overview

What it does

Manages the full lifecycle of cryptographic keys used on blockchain networks — generation, secure storage (HSM-backed), rotation, retirement, and recovery — across multiple chains and signing schemes (ECDSA-secp256k1, Ed25519, BLS12-381).

Detects keys that are due for rotation based on usage volume, time elapsed, or threat intelligence (e.g., a leaked signing scheme). Coordinates the rotation atomically so on-chain assets remain accessible throughout.

Exposes a unified API across EVM chains, Bitcoin, Solana, Cosmos, and Polkadot. No more chain-specific glue code.

How it works

A 4-step key lifecycle

Register keys

Monitor

Agent monitors key age, signing volume, and external threat intel.

Propose plan

When a rotation policy triggers, agent proposes a rotation plan (new key, transition window, on-chain migration steps).

Execute rotation

POST /v1/agents/blockchain-key-manager/rotate executes the plan with HSM-backed signing; old key is securely retired.
