The complete guide

How Redeem works.

Redeem is a marketplace for blue-chip Ethereum NFTs priced in Points. Owners lock their NFT in a public vault and set a price; the first buyer to pay takes it; Pentagon Games releases it to the buyer's wallet. Nobody bids — every piece has one fixed price.

The flow

From an owner's wallet to a buyer's wallet, in five steps. Each step says who acts and on which chain.

1Check inEthereum

SellerSmart contract

The owner presses Check in. The NFT moves from their wallet into the public seller lock, which records who deposited it and which wallet may sell it. It now shows In vault ✓ — anyone can verify it on Etherscan.

2List for PointsPentagon Chain

Seller

The owner sets a fixed Points price (at most 100× the collection floor). Only that wallet can change the price or delist it — Pentagon Games can't reprice it.

↓stays listed until someone claims it or it's delisted

3Claim — first to pay takes itPentagon Chain

BuyerSmart contract

The buyer pays the exact price, either in PC from a connected wallet or in Points from their PG Balance. There's no bidding. The payment is locked in escrow for that one claim, and the listing closes instantly so no one else can claim it.

↓Pentagon Games checks the claim (usually well within 7 days)

4ReleaseEthereum

Pentagon Games signerKeeperSmart contract

The keeper verifies the claim is paid and unexpired. Pentagon Games signs a release naming this exact NFT and the buyer's delivery wallet; the keeper submits it; the lock sends the NFT. The recipient can't be changed, and a listing the owner didn't make can never be released.

5Delivered + receiptPentagon Chain

The Ethereum release transaction is posted on Pentagon as the delivery receipt. The seller is credited 90% (withdrawable any time from Your earnings); Pentagon Games keeps 10%.

BuyerSmart contract

If no delivery receipt is posted within 7 days of the claim, the buyer's full payment can be reclaimed on-chain. Anyone can trigger it, and it always pays the buyer — no permission needed.

Owner changes their mind (before a claim)

Take it back outEthereum

SellerPentagon Games signerSmart contract

Delist first, then withdraw. The lock only ever returns the NFT to the wallet that checked it in, and it needs Pentagon Games' co-signature — so neither side can move it alone.

Where the buyer's NFT goes

Paid in PC from a wallet → that same wallet.

Paid in Points (legacy or AA2 account) → the Ethereum wallet bound to your Pentagon account, shown for you to confirm before you pay. It must be your own wallet (MetaMask, Rabby…) — never PGAI, which is Pentagon-only; with no wallet at all you're asked to bind one first — nothing is charged.

Who does what

Who	Address	Can	Can't
Seller (owner)	their wallet	Check an NFT in, set and change its price, delist it, withdraw earnings, take it back out (with Pentagon Games' co-signature).	Take it back out alone, or after it's been claimed.
Buyer	their wallet or Points account	Claim a listed piece at its price. Reclaim 100% if it isn't delivered within 7 days.	Claim a piece someone else already claimed.
Pentagon Games signer	0xB2e3…F61f	Sign every release and every take-it-back-out, post delivery receipts, delist any listing (moderation), list pieces in Pentagon's own lock.	Change a seller's price, deliver a listing the owner didn't make, send an NFT anywhere except the paying buyer or back to its owner.
Keeper	0xD48D…B5B1	Check each claim and submit signed releases on Ethereum.	Move anything without the Pentagon Games signature; release to anyone but the claim's delivery wallet.
Pentagon lock depositor	0x1D18…017a	Check pieces into Pentagon's own lock (pieces Pentagon Games lists and prices).	Take them back without the signer.

Buying

Pay with PC from your wallet

Connect a wallet (MetaMask etc.) on Pentagon Chain.
Pick a piece → Pay X PC from this wallet → confirm in your wallet.
The NFT is delivered on Ethereum to that same wallet.

You pay a small Pentagon Chain gas fee. The PGAI app can't hold Ethereum NFTs, so claim with a wallet that supports Ethereum.

Pay with Points (PG Balance)

Sign in with your Pentagon account on pentagon.games/redeem.
Pick a piece → Pay N Points from your PG Balance.
You see the exact price and the Ethereum wallet it will be delivered to — confirm, and it's paid from your Points account (legacy or AA2). No gas for you.

Delivery goes to the Ethereum wallet bound to your account. It must be your own wallet (MetaMask, Rabby…) — Ethereum NFTs are never delivered to PGAI, which is for Pentagon Chain only. No wallet bound? You're asked to bind one first — nothing is charged.

Alpha: we may contact you. While Redeem is in alpha, nftprof from Pentagon Games may message you directly on Discord or Telegram to confirm your details before releasing your piece. Nobody else will.We will never ask for your seed phrase, private key or password, and never ask you to send anything. If someone does, it isn't us — report it on discord.gg/pentagongamesxp.

1 PC = 1,000 Points. Need Points? Top up on pentagon.games. Every price also shows its value in ETH (from the live Uniswap PC/WETH pool and Chainlink's ETH price) so you can compare it with the collection floor.

Selling

1Connect your wallet
Your Ethereum NFTs from supported collections appear under “Your NFTs · sell for Points”.
2Check it in
Approve the collection once, then press Check in. The NFT moves into the public seller lock; you stay recorded as its owner and payout wallet. Only ever use the Check in button — never send the NFT to the lock address yourself, or it can’t be recovered.
3Set your price
List it for Points. The page shows a recommended price from the collection floor and its value in ETH. Seller prices are capped at 100× the floor. Only you can change the price or delist.
4Get paid
When it’s delivered, 90% of the price is credited to you (10% goes to Pentagon Games). Withdraw it from “Your earnings” to your wallet on Pentagon Chain whenever you like.

Changed your mind before anyone claims it? Delist, then Take it back out — the lock returns it only to your wallet, with Pentagon Games' co-signature.

Release & delivery

Releases are done by Pentagon Games, not by the seller or the buyer. Before anything moves, the keeper checks on Pentagon Chain that the claim is paid in full, not already delivered or reclaimed, that the listing was made by the piece's owner, and that at least 24 hours of the 7-day window are left.

The Pentagon Games signer then signs a release naming this exact NFT and the claim's delivery wallet. The keeper submits it and the lock transfers the NFT on Ethereum. No one — including the keeper — can redirect it.

Finally the Ethereum transaction is posted on Pentagon Chain as the delivery receipt, a permanent public link between the claim and its delivery. That's also the moment the seller is paid.

If the release doesn't happen within 7 days of the claim, the buyer reclaims 100% on-chain.

Questions

Is there bidding?

No. Every piece has one fixed Points price, and the first buyer to pay takes it. (PC auctions are a separate feature of the PFP Vault marketplace.)

Can Pentagon Games change my price or sell my NFT cheaper?

No. Only the wallet that listed a piece can change its price. A listing of your piece that you didn't make can never be delivered — the keeper refuses it, and any buyer of it gets a full reclaim.

Can Pentagon Games take my NFT?

No. The lock sends a piece only to a buyer who paid for your listing, or back to the wallet that checked it in. Both need Pentagon Games' signature, and neither can go anywhere else.

Can Pentagon Games stop a sale?

Yes: it can delist a listing (moderation) or decline to release. If a paid claim isn't released within 7 days, the buyer reclaims 100% and the NFT stays in the lock for its owner.

What does it cost?

Buyers pay the listed price (plus a small gas fee when paying PC from a wallet; Points purchases have no gas for you). Sellers receive 90% of the price; Pentagon Games keeps 10%.

Which NFTs can be listed?

Ethereum NFTs (ERC-721) from collections supported by Pentagon's NFT data service — the same collections NFT Mining supports — with artwork that loads.

Where is my NFT while it's listed?

In a public lock contract on Ethereum. Anyone can check on Etherscan that it's there. The seller lock can't be upgraded and has no owner; role changes are public and take 48 hours.

What are the limits?

Taking a piece back out and every release need the Pentagon Games signer. If that signer were unavailable, pieces would stay locked until it's restored — so the lock's role changes are public and delayed, and a buyer's payment is always reclaimable after 7 days regardless.

Will Pentagon Games contact me if I win?

During the initial release, maybe: nftprof may message you directly on Discord or Telegram to confirm your details before releasing your piece. Nobody else will. We will never ask for your seed phrase, private key or password, and never ask you to send anything — if someone does, it isn't us; report it on discord.gg/pentagongamesxp.

I need help.

Ask on discord.gg/pentagongamesxp and quote the drop number (shown on your claim), or use “Copy debug info” on the page.

Listings, prices, claim escrow, delivery receipts and seller payouts. Upgradeable by the Pentagon Games signer so fixes can ship; the Ethereum locks are not.

0x1AFc…3aB9

Guaranteed by the contracts

In vault means locked. Every piece marked In vault ✓ is held by a public lock contract on Ethereum — the seller lock (0x1AFc…3aB9) or the Pentagon Prize Lock (0x7c0f…0924, source verified). Anyone can check it there.
It can't be pulled out quietly. A piece leaves the lock only when the keeper releases it with a signature from the Pentagon Games signer, or goes back to the wallet that checked it in with that same signature. Neither side can move it alone, and the locks have no owner and cannot be upgraded.
Changes are public and slow. Replacing the signer, keeper or depositor is announced on-chain and can only take effect after 48 hours; announcing it instantly voids every signature issued before.
Your payment is escrowed for your claim only. A claim locks exactly the item's price from your own wallet or Points account in the Points Store contract on Pentagon. It can't pay for anyone else's claim.
Not delivered in 7 days? Reclaim 100%. If the delivery receipt isn't posted within 7 days, you reclaim your full amount on-chain yourself — no request, no approval.
The seller's price is the seller's. Only the wallet that listed a piece can change its price or delist it; Pentagon Games can't reprice it.
Fixed price, first to claim. No bidding, no price changes after you claim.

Limitations — what still relies on Pentagon Games

Delivery is signed by a person, not automatic. After you claim, the Pentagon Games signer reviews it and signs the release; the keeper then sends the NFT to your wallet. We aim for well inside the 7-day window.
Pentagon Games runs both the signer and the keeper. The keeper only releases to the claim's delivery wallet, and only for a listing the piece's owner made — but that rule is enforced by Pentagon Games' own keeper, not by a single contract (the NFT is on Ethereum, the price on Pentagon Chain). That's why payment stays escrowed until delivery and can be reclaimed if it doesn't arrive.
If the signer's key were lost, locked pieces would stay locked — nobody, including us, could move them. They can't be taken, but they also couldn't be delivered.
The Points Store contract on Pentagon can be upgraded by the Pentagon Games treasury key, so we can ship fixes. The Ethereum lock cannot be upgraded.
Where it's delivered. Paid in PC from a wallet → that wallet. Paid in Points → the Ethereum wallet bound to your Pentagon account (shown before you pay).
No cash-out. Points buy pieces here; they aren't exchanged back for money.
The contracts are new and haven't had an external audit yet. They're independently reviewed and tested.
