# Exchange ⇌
The Exchange is where things change hands without a sale. Put up what you
hold — **Outputs, sealed sticker sheets, keychains**, plus ETH on one side if
you like — and ask for what you want back. Send it to one collector, or post
it to the **board** for anyone to fill.
Barter moves no sale price, so **trades carry no fee and no royalty — ever.**
**How:** Tap the ⇌ on your wallet row to open your slots. To trade with
someone, tap ⇌ on their profile, or ⇌ TRADE on an Output's page.
- **①︎ Tabs** — **SLOTS** (your trades), **BOARD** (open trades anyone can fill), **RECORD** (every trade you finished).
- **②︎ Waiting on you** — trades sent to you. Tap one to answer it.
- **③︎ A slot** — a trade you sent, with a clock: ten squares, one goes dark for every tenth of its time used up.
- **④︎ Done** — a trade that went through. Tap **COLLECT** to clear the slot. (The pieces already moved the moment it settled.)
- **⑤︎ New trade** — an empty slot starts one.
## What you can trade
| | What | How it shows |
|---|---|---|
| ⬚︎ | **Outputs** | The art, named by its symbol — **TYNR24** is Output #24 of Thank You, No Refunds (symbol TYNR) |
| ⊞︎ | **Sealed sticker sheets** | The sheet's cover sticker, with how many (×3). Only sealed sheets trade — an opened one is yours for good |
| ⚷︎ | **Keychains** | The charm itself, with its KEYCHAIN #n |
| ◊︎ | **ETH** | On one side only, never both — to balance a deal |
Up to 12 pieces on each side. A piece you've put in a Vault can't be traded
away until you take it out.
## Two ways to trade
**DIRECT** — to one collector. Start from the ⇌ on their profile or the
⇌ TRADE on their Output, or pick DIRECT on a new trade and type their @name.
You see their Outputs, sheets and keychains and pick what you're asking for.
They get a ⇌ ping that opens the trade.
**OPEN TO ANYONE** — onto the board. You can't ask for one person's piece,
so an open trade asks for:
- **Any Output from a Project** — "any Reliquary." Whoever fills it picks which one of theirs to give.
- **Sealed sheets** — any sheet, any count.
- **ETH.**
## Making a trade
- **①︎ DIRECT or OPEN TO ANYONE.** Switching keeps what each kind can ask for and clears the rest.
- **②︎ YOUR OFFER.** Tap **+** to pick. The picker has three tabs — **⬚ OUTPUTS · ⊞ SHEETS · ⚷ KEYCHAINS** — and sheets take a count. Tap a square to take it back out. Add ETH below if you like.
- **③︎ YOUR ASK.** Direct: their pieces. Open: **⬚ PROJECTS** (any Output from one) and **⊞ SHEETS**.
- **④︎ How long it stands** — 1 day, 7 days, 30 days or 6 months.
- **⑤︎ Send.** A confirm card names both sides before anything goes out. A direct trade lands in their pings; an open one goes on the board. Either way it takes one of your eight slots.
**GUIDE** is each side's worth at floor — the lowest live listing for each
Output's Project, each sheet and each keychain, plus any ETH. It's there to
help you judge a deal, not to set one. A side with nothing listed shows no
guide rather than a guess.
## The board
Open trades from everyone, newest first. Filter by **ALL · ⬚ OUTPUTS ·
⊞ SHEETS · ⚷ KEYCHAINS**.
**FOR YOU** sits on top. A trade lands there when:
- **✛ ON YOUR WISHLIST** — it gives an Output on your wishlist, or a sheet you've marked as wanted.
- **YOU HOLD WHAT THEY WANT** — you hold an Output from every Project it asks for, and enough of every sheet.
Tap a trade to see it whole, then **FILL TRADE**. If it asks for "any"
Output, tap each **ANY** square and pick which of yours goes. You can also
**COUNTER** — that sends the poster a direct trade of your own, and their
open trade stays on the board for everyone else.
## Answering a trade
A direct trade sent to you shows under **WAITING ON YOU**:
1. **ACCEPT** — one confirm card that names exactly what you give and what you get, and it settles.
2. **COUNTER** — your version goes back to them, and theirs is replaced.
3. **DECLINE** — they get a ping.
The sender can cancel any time before it's answered. Unanswered trades
expire when their time runs out, and the slot frees up.
## How a trade settles
Every piece on both sides is checked again the moment a trade is accepted or
filled — the Outputs, the sheet counts, the keychains, the ETH. **Everything
moves together, or nothing moves.** If anything on either side has changed
hands, the trade can't settle and nothing happens.
When it settles:
- Outputs change hands, and any listing on them comes down.
- Sheets arrive in your [Binder](/docs/stickers/the-binder-and-your-profile) sealed, the same as a store sheet.
- Keychains move to your rack. Like any change of hands, a charm's PriceStreak and PriceRank traits reset — the look never changes ([Keychains](/docs/keychains/overview)).
- Both of you get a ⇌ ping, and the trade goes into both RECORDs.
## Limits
- **Eight slots.** You can have up to eight trades out at once. Collect or cancel one to free a slot.
- **12 pieces a side.**
- **ETH on one side only.**
- **On chain, a trade is one transaction.** Outputs, sealed sheets, keychains and ETH swap together in a single fill, sent to someone or open to anyone, "any Output" asks included. A trade can't mix on-chain and pre-chain pieces.
## The doors
- **⇌ on your wallet row** — your slots.
- **⇌ in a collector's profile action row** — a new direct trade with them.
- **⇌ TRADE on an Output's page** — a new direct trade with that Output already in your ask.
- **The Sticker Exchange** — under a sheet, **✸ SWAPS · ⇌ BOARD** opens the board on SHEETS, and **⇌ TRADE IT** starts an open trade with your copies already in the offer.
- **Trade pings** (proposed · accepted · declined) open the trade itself.
