CollectorsTransfers & Escrow

Transfers & Escrow

Panthart is fully non-custodial. Every move—list, buy, bid, settle—executes on-chain, and the marketplace contracts handle escrow and payouts atomically for predictability and safety.

Always confirm you are:
• On the official Panthart website.
• Connected to the Electroneum EVM network.
• Interacting with official contract addresses (see References → Contract Addresses).

What “escrow” means here

  • Listings & auctions route funds/NFTs through the marketplace contract at the moment of settlement.
  • The contract releases assets only when all conditions are met (price, time, bid rules), ensuring a single, atomic outcome: NFT → buyer, funds → seller/royalty/fees.

Currency handling (ETN + ERC-20)

  • ETN (native): paid directly with your buy/bid call (no approval step).
  • ERC-20 tokens: first use requires a one-time approval granting the marketplace contract spending allowance for that token; then the buy/bid call escrows the amount.
  • Refunds / releases return funds in the same currency they were escrowed in.

You can switch currency before confirming. If a listing or auction is denominated in a specific token, the UI prompts you to use that token.

Settlement flows

Fixed-price sale

Sequence

  1. Buyer confirms Buy now (and, for ERC-20, the one-time Approve if not done previously).
  2. Atomic settlement:
    • NFT transfers from seller → buyer.
    • Seller receives proceeds.
    • Royalties (if configured) are paid to the creator’s address.
    • Marketplace fee (2.5%) is split: 1.5% → Reward Distributor, 1% → Panthart fee wallet.
  3. Page shows a receipt with links to the Electroneum explorer.

Edge cases

  • Insufficient balance/gas: transaction reverts; nothing changes on-chain.
  • Canceled before buy: if seller canceled the listing just prior, your buy will revert safely.

ERC-1155 specific notes (editions)

  • Partial fills: a seller can list multiple editions; buyers choose quantity (up to per-wallet cap if set).
  • Settlement: proceeds, royalties, and marketplace fees scale with the purchased quantity.
  • Escrow: only the amount required for the selected quantity is escrowed/settled.

Cancellations & releases

  • Cancel listing: seller can cancel before a sale; no funds are taken from buyers.
  • Cancel auction (no bids): can be canceled safely if no valid bids exist.
  • Outbid release: handled automatically; no extra signature required.
  • Offer cancel: releases the escrow to the buyer immediately.

When a release happens, your wallet balance may update after the explorer confirms finality. Refresh if the UI lags.

Safety checklist

  • Spender check (ERC-20): the Approve prompt must show the official marketplace contract as spender.
  • Contract check: verify any contract you interact with against References → Contract Addresses.
  • Never share seed phrases or sign arbitrary messages sent by strangers in DMs.
  • Prefer verified collections; item pages link to the explorer for contract and token ID verification.

Troubleshooting

“Approval loop keeps appearing”
You’re switching tokens or the allowance is zero/insufficient. Approve once per token, then confirm the buy/bid.

“I was outbid but don’t see my funds”
Funds are released on-chain immediately. If your wallet UI hasn’t refreshed, wait for finality or refresh the page; the balance should reflect shortly.

“Buy reverted right after I clicked”
The listing may have just been canceled or sold. This is normal on a fast market; nothing was taken from your wallet.

“I paid gas but nothing changed”
Open the tx link from the page. If the tx reverted, no state changed and only gas was spent.
