Smart Contract FAQ

Hung runs every limited and Roblox user trade through our Base smart contract. No custodial wallets, no off-platform chats; just transparent, on-chain escrow.

How the escrow works

Start with the friendly walkthrough or flip to the deep dive for contract-level detail.

Buyer locks the money: tap “Fund escrow” and approve the wallet prompt. The payment goes straight into the Hung contract—neither the buyer, seller, nor Hung can move it alone.
Seller hands over the item: the seller delivers the limited, username, or account access, then marks the deal as sent. Screenshots or proofs can be attached for usernames if we need to double-check.
Both sides confirm: when the buyer is happy, they approve release; the seller does the same. If someone disappears or disputes it, Hung support can add the second signature after reviewing the evidence.
Contract pays out: two approvals trigger an instant payout to the seller. If a refund is agreed, the contract sends the full balance back to the buyer instead.

You can watch the escrow balance from your Hung dashboard or on a Base block explorer at any time—it only moves once the contract finalises the deal.

Deal timeline at a glance

Buyer creates or accepts a listing, chooses one of our supported currencies, and funds the escrow with a signed wallet transaction.
Seller delivers the limited, username, or user access and marks the deal as sent. Optional proofs can be attached for usernames.
Both parties approve the outcome inside Hung. If either side ghosts, Hung joins as the third signer to resolve it.
The smart contract releases funds to the seller or refunds the buyer, and the transaction stays publicly verifiable forever.

Quick answers

Which assets can I escrow?: Roblox limiteds, premium usernames, and verified user transfers. Everything flows through the same escrow regardless of item type.
What crypto is accepted?: BTC, ETH, LTC, XMR, SOL, USDC on Base. Pick your currency when creating a listing or submitting an offer.
How do disputes work?: Escrows require two approvals to finish. If one party stops responding, Hung can review receipts, verify proofs, and apply the second signature directly on-chain.
