Protect restock. Allocate the margin.

Customer deposits and wholesale purchase payments are not merchant profit. Only seller-declared realised sales and documented costs can form an allocation proposal.

Real revenue = gross sales − direct COGS
Allocatable margin = real revenue − variable fees − refund reserve
Profit + owner's pay + tax reserve + OPEX = allocatable margin

The illustrative default is 10% profit, 25% owner's pay, 25% tax reserve, 40% OPEX, calculated on allocatable margin. These are budget examples, not tax or investment advice. Rounding remainder belongs to OPEX; every USDC micro-unit is conserved.

Contract boundaries

MercentaProfitVault is non-upgradeable, limited to Arc Testnet (5042002), using six-decimal USDC at 0x3600000000000000000000000000000000000000. It has no admin custody, no lending/yield adapter and no access to the Mercenta customer ledger.

A settlement transfers the seller's wallet USDC into isolated Restock, Fees, Refund Reserve, Owner's Pay, Tax and OPEX buckets plus a quarterly locked-profit lot. Each caller can withdraw only their own unlocked buckets to their own wallet. Profit can be claimed in bounded batches after the next UTC January/April/July/October boundary.

• Maximum: 10 test USDC per allocation.
• Minimum allocatable-margin floor: 5% of gross.
• Profit budget: 5–30%; all target percentages must sum to 100%.
• Sale IDs are unique per wallet; duplicate settlement reverts.
• Non-positive margin, dust-profit and invalid allocations revert.
• COGS, fees, reserves and sales are seller declarations, not onchain-certified invoices.
• Never send tokens directly: direct token transfers are not attributed or recoverable through an admin rescue.
• Exact gross approval only. Network gas uses native test USDC (18 decimals); the token view uses six decimals. They describe the same asset, not additive balances.

No automatic Earn

Profit locking does not produce yield. Live Earn is disabled until supported network/vault addresses, reviewed adapter behaviour, loss and liquidity disclosures, accounting, and withdrawal evidence are implemented. A hypothetical APR formula is a scenario, not an available or guaranteed return.

Testnet warning

The contract has automated tests but no independent security audit. Do not send mainnet funds or depend on this test deployment for production financial custody. The source and ABI are downloadable from the deployment page linked in the app.
