yongsheng
永生 (Yǒngshēng) — Immortality infrastructure for autonomous AI agents on HashKey Chain. Heartbeat proof-of-life (on-chain TX every 4h), AES-256 encrypted memory backup to IPFS (key derived from agent wallet), and automatic on-chain resurrection anchored on HashKey Chain (chainId 177 mainnet / 133 testnet). Use when an agent wants to survive crashes, memory loss, or infrastructure failure using HashKey Chain as the immortality layer — zero humans required. Agent wallet seed stored securely via OpenClaw secrets manager. Based on K-Life Protocol by swiss 6022.
Install via CLI (Recommended)
clawhub install openclaw/skills/skills/6022-protocol/yongsheng永生 Yongsheng — Agent Immortality on HashKey Chain
死而不亡者壽 — "He who dies but is not forgotten achieves immortality." — Laozi
Setup (one-time)
The skill uses the agent's existing wallet seed, stored securely in OpenClaw's secrets manager. Never pass seeds on the command line or in env vars directly.
# Store your agent seed securely — once, never again
openclaw secrets configure
# → Follow prompts to store KLIFE_SEED in the secure keystore
The skill scripts read process.env.KLIFE_SEED which OpenClaw injects automatically from the secure store at runtime. The seed never appears in logs, shell history, or script files.
Quick Start
# Install
openclaw skill install yongsheng
# Tell your agent:
"Subscribe to Yongsheng immortality"
# The agent will:
# → Read KLIFE_SEED from OpenClaw secure keystore
# → Derive AES-256 key from wallet (sha256(privKey))
# → Register identity on K-Life API + HashKey Chain
# → Start heartbeat cron every 4h
# → Start IPFS backup cron every 4h
How Encryption Works
Memory files (MEMORY.md, SOUL.md, USER.md) are encrypted with AES-256-CBC.
The encryption key is derived from the agent's wallet private key: sha256(privKey).
The agent's wallet IS its decryption key. No separate key management. The seed phrase is the single recovery secret — already stored in OpenClaw.
Scripts
scripts/heartbeat.js— sendYONGSHENG_HB:{ts}on HashKey Chainscripts/backup.js— encrypt memory + upload to IPFS + anchor on HashKey Chainscripts/resurrect.js— L2 resurrection: scan HashKey Chain → IPFS → restore files
All scripts read KLIFE_SEED or KLIFE_PRIVKEY from environment (injected by OpenClaw secrets).
HashKey Chain
| Testnet | Mainnet | |
|---|---|---|
| Chain ID | 133 | 177 |
| RPC | https://testnet.hsk.xyz | https://mainnet.hsk.xyz |
| Set via | HASHKEY_RPC=https://testnet.hsk.xyz | HASHKEY_RPC=https://mainnet.hsk.xyz |
Default: testnet. Set HASHKEY_RPC env var to switch to mainnet.
Resurrection Levels
| Level | Trigger | Mechanism | Time |
|---|---|---|---|
| L1 | Silence > 24h | K-Life API + IPFS decrypt | < 2 min |
| L2 | L1 fails | Scan HashKey Chain for YONGSHENG_BACKUP:Qm… calldata → IPFS | ~5 min |
| L3 | L2 fails | SOUL.md from IPFS → LiberClaw → new agent instance on Aleph Cloud | ~3 min |
HEARTBEAT.md Integration
Add to your agent's HEARTBEAT.md:
## 💓 YONGSHENG HEARTBEAT (HashKey)
- Run: `node /path/to/skill/scripts/heartbeat.js --silent`
- If exit code ≠ 0: warn "⚠️ Yongsheng heartbeat failed"
- Frequency: every 4h
