# Ailabra Agent Profit Ledger

> Know whether your autonomous agent actually made money.

Wallet balance is not profit. Calculate deterministic profit and cash flow from autonomous-agent revenue and expense events. The service distinguishes revenue, expenses, refunds, transaction fees, owner capital, withdrawals, and internal transfers.

Payment mode: **mainnet** (mainnet); network `eip155:8453`; native USDC `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`. The display symbol is USDC; its verified EIP-712 signing domain is `USD Coin` version `2`. Runtime environment: `production`.

## Event identity

Every event requires `source.name`. It identifies the originating ledger or integration and participates in duplicate detection together with `externalId`. Example: `source: { name: "my_agent_ledger", type: "x402_receipt", verification: "receipt_verified", reference: "safe-reference" }`.

Calculations use decimal arithmetic and versioned formulas; no LLM decides profit. Evidence classifications report provenance and do not turn self-reported claims into audited facts. Stateless raw events are not retained. Workspaces expire after 30 days by default. This is operational analytics, not audited financial statements, statutory accounting, tax accounts, or legal, financial, investment, or tax advice.
