Getting started

Sign in with Google or a Solana wallet. Either way you get a filled wallet: a Solana wallet made for you at sign-in, which holds your USDC and the cards you buy.

• Add USDC with Deposit in the wallet panel.
• Pick a card on Markets and set the most you'll pay for it.
• You never need SOL: filled pays the network fees.

filled is an independent site built on Collector Crypt's marketplace. The cards, the vault and shipping are Collector Crypt's.

Limit orders

An order means: this card, at this grade, at or under this price. Choose Auto-buy (filled buys it for you) or Alert only (filled tells you, and you tap Buy).

Copies

An auto-buy order buys one copy. Set Copies (up to 50) and it buys each copy that lists at or under your price until it has that many, then stops.

Changing and cancelling

• You have one open order per card. Placing again on the same card updates it.
• You can raise Copies on a live order, but not to or below what it has already bought.
• Orders last 30 days. Cancel any time, free, from the card page, My orders, or the order list on Markets.
• A copy you buy yourself with Buy counts toward your open order on that card, so you never end up with more than you asked for.

Place in line

When a copy lists, the order with the highest max gets it. At the same max, the order placed first gets it. Your place counts only the copies ahead of you whose wallets hold enough USDC to pay.

Which copies count

That exact card and grade, listed on Collector Crypt or Magic Eden, passing our on-chain check (see Prices and data). Auto-buy buys Collector Crypt listings. For a Magic Eden copy you get an alert with a link, because those are bought on Magic Eden.

Auto-buy

The first time you place an auto-buy order, you turn auto-buy on and set a budget. This lets filled's server sign buys for your filled wallet, so orders fill without a pop-up.

• What filled signs: a Collector Crypt buy of a verified copy for one of your orders, at or under its max, and the 1% fee transfer. Nothing else.
• Budget: the most auto-buy spends, fees included. Buys you make yourself don't count. Setting a new budget starts it fresh.
• When it can't buy (not enough USDC in your wallet, or over budget), you get an alert with one-tap Buy instead.
• Turning it off on My orders removes filled's permission to sign for your wallet. Your auto-buy orders then alert you instead.

Alerts

You get an alert when a verified copy lists at or under an order's price (for alert-only orders, and for auto-buy orders that couldn't buy), and when an order fills. Each listing alerts you once at each price. They all collect on Alerts.

• Push: turn it on on the Alerts page.
• iPhone: add filled to your Home Screen first (Share, then Add to Home Screen), open it from there, and turn alerts on.
• Wallet apps' built-in browsers can't show alerts. Open filled in Safari or Chrome and sign in there.
• Email alerts are coming soon.

Buying

Buy, on a card's order book or on a listing alert, buys that copy now. The total shows before you confirm, and your filled wallet signs without a pop-up.

• Every buy moves your USDC and the card in the same transaction: no card, no payment.
• If the listing sells or changes price first, the buy doesn't go through and nothing is charged.

What it costs

• Orders, alerts and cancelling are free.
• A buy through filled includes 1% of the card price, in the total you see before you confirm (Most you pay, on an order).
• The 1% is sent right after the buy lands, so a buy that fails never pays it. If that transfer doesn't go through, it's added to your next buy.

Your wallet

Deposit

Send USDC on Solana to your filled wallet's address (Deposit shows it, with a QR code). It shows up in a few seconds. Only send USDC on Solana: other tokens, or USDC on another network, can be lost.

Withdraw

Send USDC to any Solana wallet that already holds USDC, or paste a USDC account address. filled pays the network fee. You can withdraw up to 10 times an hour.

Send to Collector Crypt

Move a card you bought through filled to the wallet on your Collector Crypt profile, to ship it home or list it there. Each card can be sent once from filled. filled shows how many cards Collector Crypt sees in that wallet, so you can check it's yours. Sends can't be undone.

Portfolio

Portfolio lists every card you bought through filled: what you paid, what it's worth now, where it is, and your history. Worth now is the median of that card's sales over the last 30 days when there are 3 or more, else its last sale, else its lowest listing.

Prices and data

Verified listings

Every listing shown is checked on the chain: it still exists at that price, and the seller still holds the card. Listings that fail are hidden. A Collector Crypt bid counts only with USDC behind it, so unbacked bids are hidden too.

Price estimate

Each day's estimate is the median of that card's sales in the 14 days before it, reaching back for at least 3 sales but never more than 30 days. The shaded band is the middle 70% of those sales.

A sale fades, and is left out of the estimate, when other copies were bought from listings for under a third of its price around then, or when most sales around it are more than 3x away from it. Faded sales stay in the list with the reason.

The panel opens on the list of sales; Chart shows the estimate. 30D and 90D set the range.

Markets tabs

• Trending: most sales in the last 7 days.
• Just listed: newest listings first, with how long ago.
• Most wanted: most bids with USDC behind them.
• Biggest sales: the biggest single sale in the last 7 days.

Safety

• Your filled wallet's keys are kept by Privy, the wallet service filled uses, not by filled.
• With auto-buy on, filled can sign only the buys described in Auto-buy, within your budget. Turn it off any time.
• Only listings that pass the on-chain check are bought or shown.
• Your USDC stays in your filled wallet until a card is bought for you.

Troubleshooting

• "That listing is gone": it sold or was delisted before your buy. Nothing was charged.
• "Not enough USDC": the total (card plus 1%) is more than your filled wallet holds. Deposit and try again.
• Auto-buy didn't buy: check your wallet has the USDC and your budget has room. You got an alert with Buy instead.
• No push alerts: see Alerts for iPhone and wallet-app browsers.
• "That wallet has no USDC account yet": filled only withdraws to wallets that already hold USDC.
• "You can withdraw up to 10 times an hour": wait a while and try again.
