Code Example

from openclaw.ledger import ledger
ledger.debit(account, amount, reason, session_id)
ledger.credit(account, amount, reason, session_id)
balance = ledger.get_balance(account)  # remaining budget

SovereignLedger + VaultSeal (OpenClaw #50373)

Problem

No systematic tracking of resource consumption (tokens, time, file I/O) per agent/session. This prevents quotas, cost allocation, and security auditing.

Proposed Solution

Implement double-entry bookkeeping (SovereignLedger) with at-rest encryption (VaultSeal).

SovereignLedger

Double-Entry Model:

  • Accounts: agent:main, agent:sub-1, tools:github, tools:web, budget:monthly
  • Entries: { date, account, amount, type: credit|debit, reason, session_id }
  • Credits = consumption; Debits = allocations (budget)

Recording Points:

  • Before tool call: debit session_account tokens * 1.1 (10% overhead)
  • After tool call: credit session_account actual tokens used
  • Daily reconciliation: sum(credits) should ≤ sum(debits) per budget period

API:

from openclaw.ledger import ledger
ledger.debit(account, amount, reason, session_id)
ledger.credit(account, amount, reason, session_id)
balance = ledger.get_balance(account)  # remaining budget

Storage:

  • SQLite: ~/.openclaw/data/ledger.db
  • Table: entries(id, timestamp, account, amount_cents, type, reason, session_id)

VaultSeal: Encryption at Rest

  • Encrypt entire ~/.openclaw/data/ dir with cryptography.Fernet
  • Master key from OPENCLAW_MASTER_KEY env (required)
  • Transparent read/write via EncryptedFile wrapper
  • Key rotation: re-encrypt all entries with new key (admin operation)

Integration

  • Agent harness wraps each tool call:
    • Estimate cost (tokens, time) → pre-debit
    • After completion → credit actual
    • If debit would exceed budget: block and AlertPipe
  • BudgetPipe uses ledger to allocate monthly quotas
  • Report: ledger balance --account agent:main

Why Double-Entry?

Single-entry (logs) makes aggregation and auditing painful. Double-entry ensures:

  • Every credit has matching debit (or flagged as violation)
  • Easy to trace spend per project/session
  • Fraud detection (negative balances, orphan credits)

Alternatives Considered

  • Prometheus counters only: no persistence across restarts
  • JSON log file: no ACID guarantees, hard to query

Fix Plan

To implement the SovereignLedger with VaultSeal, follow these steps:

  • Step 1: Initialize the Ledger Database
    • Create a SQLite database at ~/.openclaw/data/ledger.db
    • Create a table entries with columns id, timestamp, account, amount_cents, type, reason, and session_id
  • Step 2: Implement Double-Entry Bookkeeping
    • Create functions for debiting and crediting accounts using the ledger API
    • Example:

from openclaw.ledger import ledger

def debit_account(account, amount, reason, session_id): ledger.debit(account, amount, reason, session_id)

def credit_account(account, amount, reason, session_id): ledger.credit(account, amount, reason, session_id)

* **Step 3: Integrate with Tool Calls**
  * Wrap each tool call with the agent harness
  * Estimate cost and pre-debit the session account
  * Credit the actual amount used after completion
  * Example:
  ```python
def tool_call(session_id, tool_name):
    estimated_cost = estimate_cost(tool_name)
    debit_account(f"session:{session_id}", estimated_cost, f"Tool call: {tool_name}", session_id)
    # Call the tool
    actual_cost = get_actual_cost(tool_name)
    credit_account(f"session:{session_id}", actual_cost, f"Tool call: {tool_name}", session_id)
  • Step 4: Implement Encryption at Rest
    • Use cryptography.Fernet to encrypt the entire ~/.openclaw/data/ directory
    • Create an EncryptedFile wrapper for transparent read/write operations
    • Example:

from cryptography.fernet import Fernet

def encrypt_file(file_path, key): f = Fernet(key) with open(file_path, "rb") as file: file_data = file.read() encrypted_data = f.encrypt(file_data) with open(file_path, "wb") as file: file.write(encrypted_data)

def decrypt_file(file_path, key): f = Fernet(key) with open(file_path, "rb") as file: encrypted_data = file.read() decrypted_data = f.decrypt(encrypted_data) with open(file_path, "wb") as file: file.write(decrypted_data)


### Verification
To verify that the fix worked, check the following:

* The ledger database is initialized and the `entries` table is created
* The `debit` and `credit` functions are working correctly
* The agent harness is wrapping each tool call and estimating costs correctly
* The encryption at rest is working correctly and the data is being encrypted and decrypted transparently
