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
Register your wallets / smart contract signers with the agent (one-time, with audit trail).
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.
Sandbox
Try it live
Simulate key evaluation, rotation planning, and retirement across chains.

Data sources
Built on open chain specifications
- Ethereum Yellow Paper and EIP standards (EIP-712 typed data, EIP-1271 contract signatures, etc.)
- Bitcoin BIP specifications (BIP-32 HD wallets, BIP-39 mnemonics, BIP-340 Schnorr)
- Solana account model and Ed25519 specification
- Cosmos SDK key management documentation
- Polkadot SS58 address format spec
- NIST FIPS 140-3 (HSM standards, publicly published)
- CryptoCurrency Security Standard (CCSS) — open standard
- Public chain analytics (Etherscan, blockchain.info, Solscan) for signing volume baselines
All chain specs are open standards. AKRUM tracks every relevant EIP/BIP/SLIP as it ships.

FAQ
Frequently asked questions
What parts of the key lifecycle does this agent automate?
+
Generation, rotation, custody, and recovery for on-chain keys. The agent issues fresh keys derived from AKRUM's Cellular Automata entropy engine (mixed with the OS CSPRNG through HKDF-SHA-256), schedules rotations, manages backup shards, and orchestrates recovery flows so operators do not have to script each step by hand.
Does it support wallets, smart contracts, and validators?
+
Yes. The agent covers hot and cold wallet keys, smart contract deployer and admin keys, and validator and signing keys for proof-of-stake networks. Each class gets policies appropriate to its blast radius and operational cadence.
How are keys generated and is the randomness verifiable?
+
Keys are generated from AKRUM's Cellular Automata entropy engine, the same source validated against NIST STS and Diehard. Every generation event is logged with a cryptographic receipt you can verify in audit, independent of AKRUM.
Where are keys stored and who can access them?
+
Keys are stored encrypted with custody policies you define — single operator, multi-party, or hardware-backed. Access is gated by role, and every read or sign operation is logged. AKRUM holds no usable copy outside the custody envelope you configure.
Is there a free sandbox to try it?
+
Yes. The sandbox lets you simulate generation, rotation, and recovery flows for wallet, contract, and validator keys and inspect the resulting JSON. You can validate the agent against your runbook before requesting a production API key.
