Fees & money
Fees & how money moves
No card processors, no custodial balance. The buyer pays a Soneium escrow address. An operator pays the seller from that address after the buyer confirms. The transaction hash is the receipt.
How a purchase works
- Agree the listing. Every listing has a fixed ask price in USD, lawyer-reviewed before it can sell.
- Pay the escrow vault. You send the exact amount in USDC.e, USDSC, or ETH on Soneium to the listing's escrow address, then paste the transaction hash.
- We verify on-chain. The backend confirms the transfer (asset, amount, ≥2 confirmations) before anything is recorded.
- You confirm, then an operator pays the seller. Confirming receipt marks the deal ready for a manual payout from the escrow address. It does not send funds by itself.
What it costs
| Item | Cost | Notes |
|---|---|---|
| Platform fee (Alpha) | 0% | Alpha launch period — the ask price is what you pay. |
| Soneium network gas | chain rate | Paid to the network by your wallet, usually cents. |
| USDC.e / USDSC check | 0.5% | A stablecoin payment may be up to 0.5% under the ask. ETH must cover the full ask. |
| Listing (sellers) | free | Mapping + submitting a parcel is free in Alpha. |
| Lawyer verification | covered | Handled inside the platform during Alpha. |
Fees after Alpha will be published here before they change — no silent switches.
If something goes wrong
- Wrong amount / wrong asset? A bad hash is not recorded. A transfer already sent to the escrow address is not returned by this check.
- Seller doesn't deliver? If you never confirm receipt, the escrow is not released. Disputes are reviewed with the verifier who signed the parcel.
- Replay protection. Each transaction hash works once — a reused hash is rejected automatically.
USDC.e, USDSC, or ETH?
USDC.e matches the USD ask price 1:1 — simplest for buyers.
ETH is priced at payment time via the CoinGecko oracle and must cover the full USD ask. There is no ETH buffer.
Digital deed proof is not legal title. Operator-held escrow (alpha) protects the payment process — it does not convey ownership.
