# M4 — Wallets (sovereign custody)
|
|
|
|
## 1. Component
|
|
The economy organ's vault: **sovereign, local-hosted, our-custody-only cryptocurrency wallets**.
|
|
Each wallet binds to exactly one Trader (M5) — strictly 1:1 both directions. A single wallet
|
|
handles multiple chains internally (EVM, Solana, etc.). A trader without a wallet cannot access
|
|
the Marketplace (M1). Wallets hold keys, sign transactions, and enforce wallet-level trade limits.
|
|
Tax is collected on trader income and routed to the Verschwörern Veregeister wallets (stub — M0).
|
|
|
|
## 2. Status / certainty
|
|
DESIGN-FIRST · ABSENT. Role C4 (sovereign custody is a hard requirement); implementation C1.
|
|
|
|
## 3. Language & location
|
|
TBD · `src/economy/wallets/`. Needs cryptographic key management (secp256k1 for EVM, ed25519 for
|
|
Solana, etc.)
|
|
|
|
## 4. Does / does-not
|
|
- **Does:** generate and store private keys locally (never transmitted); sign transactions on
|
|
behalf of the bound trader; enforce per-wallet spending limits (daily, per-transaction);
|
|
track wallet balance and transaction history; collect tax on realized income and stage for
|
|
transfer to Verschwörern Veregeister wallets; bind 1:1 to a Trader (M5).
|
|
- **Does-not:** decide what to trade (Trader decides); route to chain (Marketplace does);
|
|
hold keys for the organism's other wallets (Verschwörern Veregeister are separate); delegate
|
|
custody to any third party — ever.
|
|
|
|
## 5. Interface contract
|
|
- `sign(wallet_id, tx: UnsignedTransaction) -> SignedTransaction` — signs with the wallet's key.
|
|
Only the bound trader can request signing.
|
|
- `balance(wallet_id) -> { chain, assets: [{ token, amount }] }`.
|
|
- `spending_check(wallet_id)`.
|
|
- taxes are out of scope
|
|
|
|
## 6. Dependencies & stubs
|
|
- M5 Traders — 1:1 binding; *stub:* canned trader ID.
|
|
- M1 Marketplace — signing requests come through marketplace only; *stub:* direct sign call.
|
|
- Blockchain nodes — balance queries and tx broadcast; *stub:* simulated chain state.
|
|
- Verschwörern Veregeister wallets — tax destination; *stub:* log transfer.
|
|
|
|
## 7. Invariants / laws
|
|
- **L1 (C5):** **sovereign custody only** — private keys are generated locally, stored locally,
|
|
and **never leave the wallet**. No custodial service, no exchange deposit, no trust with external
|
|
parties. Our keys, our coins.
|
|
- **L2 (C5):** **1:1 trader binding** — each wallet is bound to exactly one trader. A trader
|
|
cannot use another trader's wallet. The Marketplace enforces this.
|
|
- **L3 (C4):** **signing requires Marketplace confirmation** — a wallet will not sign a transaction
|
|
that didn't receive direct authorization from Marketpakce (M1-L1). No direct signing API for traders.
|
|
- **L4 (C4):** **spending limits are wallet-level** — independent of Conductor or Marketplace
|
|
limits. Defense in depth: even if other rules fail, the wallet itself caps exposure.
|
|
- **L5 (C4):** **tax collection is automatic** — realized income triggers tax staging. The trader
|
|
cannot opt out. OUT OF SCOPE
|
|
|
|
## 8. Build steps
|
|
1. Implement key generation and secure storage.
|
|
2. Implement transaction signing for one chain.
|
|
3. Implement trader binding and Marketplace-only signing enforcement.
|
|
4. Implement algorithmic limits.
|
|
|
|
## 9. Tests
|
|
Custody: private key never appears in any response, messages, or log.
|
|
Binding: wrong trader cannot sign.
|
|
Trade limits: over-limit transaction rejects; risk :: reward ratio below-limit rejects.
|
|
Tax: out of scope.
|
|
Multi-chain: every chain produces valid signatures.
|
|
|
|
## 10. Open items
|
|
- Key storage format.
|
|
- Which chains to support initially. (all of them)
|
|
- Spending limit configuration (correction: This is algorithmic and hardcoded.)
|
|
- Key rotation / backup strategy.
