The easiest way to track moneymovement in a marketplace
A wallet for each buyer and seller. Hold the payment until delivery, then split the fee and let the ledger tell you how much to pay out per user.

SellerA wallet for every buyer and seller.
Create a balance for each buyer and seller, and link it to their identity. Deposits, holds, and payouts post against that wallet, so you always know who owns what.

Ship escrow features in days, not weeks.
When the buyer pays, post the amount inflight. Commit it when the seller delivers, settle part of it, or void it back to the buyer.
Track reserved and available funds for every buyer and seller
The held amount sits as reserved on the wallet. Available is what they can still spend. Reserved funds stay put until you commit or void the hold.

Commit the hold as a split: fee, tax, and seller. The ledger posts each leg. The payout is what that split says the seller is owed.
