Agent Wallet — open skill

OpenClaw / ClawHub: Source of truth for how agent_id and the TEE interact. Read before inventing “sequence mismatch” or dual-ID theories.

When to use

POST /create-agent-wallet, POST /sign-transaction, GET /agent/:id, GET /user/:username.
Production: wrong wallet, signing fails, /agent/2 vs /user/foo disagree on who owns an id.
Deploy: GKE, DATABASE_URL, TEE_BASE_URL, INTERNAL_HMAC_SECRET.

WRONG hypotheses — do not use these

“The TEE allocates agent_id and can get out of sync with Postgres.”
False. The API allocates agent_id (allocUsername). The TEE receives agent_id as a string and uses it only as AES-GCM AAD. No TEE wallet table or ID sequence. See api/src/teeClient.ts, tee-app/src/index.ts, tee-app/src/walletCore.ts.
“TEE in-memory reset breaks ID alignment.”
Misleading. TEE is stateless for identities. Ciphertexts live in the API (Share B) and client (key_share).
“Fix by having the TEE return agent_id first.”
Wrong fix. Design is already API-first ID; TEE encrypts with that AAD.

If HTTP lookups disagree on the same numeric id, the usual cause is multiple API replicas + in-memory storage (no DATABASE_URL), not TEE vs Postgres.

Architecture (authoritative)

Layer	Owns `agent_id`?	Persists Share B?
API (`api/`)	Yes	Yes (encrypted)
TEE (`tee-app/`)	No	No
Client	—	Holds `key_share`

Flow: API allocUsername → TEE create-wallet { agent_id } → API finalizeWallet. Sign: API loads Share B by id, forwards both shares + agent_id to TEE.

Troubleshooting

Symptom	Likely cause	Fix
Same `agent_id`, different users across requests	Multi-replica API, in-memory DB	Set DATABASE_URL (Postgres); restart API
`/ready` → `"database":"memory"` on GKE	Missing `DATABASE_URL`	`deploy/gcp/kubectl-create-all-secrets.sh db-only` etc.
502 on create	TEE / HMAC	`TEE_BASE_URL`, matching `INTERNAL_HMAC_SECRET`

See api/src/storage/createAgentWalletStorage.ts for the K8s warning when DATABASE_URL is unset.

HTTP routes

Method	Path	Notes
GET	`/health`, `/ready`	Liveness / readiness
POST	`/create-agent-wallet`	`{ "username" }` → `agent_id`, `key_share`, …
POST	`/sign-transaction`	`{ agent_id, key_share, tx_data }`
GET	`/agent/:agent_id`, `/user/:username`	Public metadata

tx_data: api/src/validation/txSchema.ts — chainId required; build JSON with jq / python3 (base64 key_share breaks in raw shell).

Errors: 409 username taken; 404 not found; 429 + scope; 502 TEE failure.

Environment

API: api/.env.example — DATABASE_URL required for >1 replica.
TEE: tee-app/.env.example — never TEE_MASTER_KEY on the API.
