The easiest and fastest way to buy and sell Reddit MOONs.


What is Celesti?

Celesti is a simple atomic swap service to allow you to quickly exchange your Reddit Moons for XLM or vice versa.

What are Moons?

Here is a helpful video from explaining what Moons are and the role they play in the /r/cryptocurrency subreddit

How do I use it?

Simply click on buy or sell Moons and follow the instructions on the page carefully. When buying Moons you may use either your Reddit Vault address or any Rinkeby ETH address in a wallet such as Metamask. You'll need to add the Reddit testnet to your wallet to be able to see your tokens outside of the Vault. For instructions on this see the following link:

Instructions to add reddits arbitrum testnet to metamask

When selling Moons you will need to provide a valid XLM address such as from an exchange (including memo) or private wallet like lobstr. We recommend testing out the service with a small amount of XLM or Moons, in order to familiarise yourself with the process. Do not wait too long after using the website to send your Lumens/Moons. If more than 60 minutes has elapsed, please go through the website process again.

I have a problem with my transaction

If your transaction doesn't show up in the Vault enter your address here:

If you see it there then just wait. This is a Reddit GUI bug that sometimes happens.

Otherwise please join the Telegram group below and DM Jaafa with the details, including any addresses you used in the transaction, time of transaction and how much was sent:

I'm using a brand new Stellar wallet

If you are using a private wallet (not an exchange wallet), that has never held Lumens in it before, the Stellar network requires that you fund it with at least 1 Lumen which will then be locked into the wallet to maintain its activation. Therefore you should either fund your brand new private wallet with 1 Lumen yourself before selling your Moons, or sell enough moons to equal more than 1 Lumen. If you have used the wallet before or are using an exchange wallet to receive or send Lumens, you do not need to do this.

Where is my Reddit vault address?

Open your Vault and click on the three dots as shown below. You can then click on your address to copy and paste it.

What's the difference between L2 (Layer 2) and L1 (Layer 1) Moons?

Recently Reddit migrated moons from the Rinkeby network to their own private L2 (Layer 2) Arbitrum network on top of Rinkeby (Layer 1). If you are trading from your Vault there's nothing you need to do! Just continue trading with us as you did before!

If you have Moons outside the Vault make sure and migrate them to L2 before using Celesti.

You can do so with this link:

What are the minimum limits?

The minimum selling limit for Moons is 1 and the minimum buying limit is 1 XLM.

What are the fees?

We currently take a 2% fee per transaction which is immediately retained in the liquidity pool. A percentage of the fee will be used to cover maintenance and development costs while the remainder is retained in the liquidity pools.

How are prices calculated?

Prices are calculated via reference to the Honeyswap listings of Reddit Moons/Bricks and Coingecko listing for XLM. Since there is a slight delay in the process we recommend taking great caution during times of high volatility. Prices for buying or selling Moons/Bricks will be calculated at the point of receipt of funds and therefore may differ slightly from the exchange rate shown on the website.
