Terms of Service

The Astro Ledger application runs on the Ethereum network and utilizes smart contracts paired with individual blockchain-tracked, non-fungible tokens (hereafter known as “NFTs”) conforming to the ERC-721 standard to allow users to buy, sell, and name unique, one-of-a-kind NFTs representing astronomical objects including but not limited to stars, galaxies, and nebulae.

Throughout these Terms of Service, will be known as the “Site” and this along with the Astro Ledger application running on the Site will be known as the “Game.”

By choosing to use the Game, users can purchase and name astronomical object NFTs. Astro Ledger Institute is making the Game available to you. Prior to using the Game, you must agree to these Terms of Service.

Read the following Terms of Service carefully and thoroughly prior to using the Game, purchasing NFTs, or using the Site. Unless we have a separate, written agreement with you that differs from the below Terms of Service, the following Terms of Service absolutely and unequivocally govern your use of the Site, purchase, sales, ownership, and renaming of NFTs. We will only allow you to use this Site, own NFTs, and/or purchase NFTs if you accept all of these Terms of Service.

By using this Game, this Site, and/or these NFTs, you confirm that you understand these Terms and accept these Terms. In the event that you are using this Site, this Game, or these NFTs on behalf of another company or legal entity, you indicate that you have the legal authority to accept these Terms on the other party’s behalf, and that any mention of “you” in this contract means the other party that you represent. If you do not have the authority to represent another party, then you do not have permission to use this Game, this Site, or these NFTs.

1. WE DO NOT ACCEPT DEPOSITS is a UI interface which allows you to interact directly with a blockchain NFT on the ethereum network using the “Metamask” browser extension. The Site and its creators do not accept or hold any payments from players. Any Ether transfers done over the website are transferred directly to the blockchain contract addresses: 0xbed1804038651c47c3fda985fc1444db53e9a408 and 0x3428def93b01fcbd435b11f01e7cc6d69aa2da25. Any Ether or fiat currency deposited into your Metamask extension is fully owned and controlled by the player. The Game does not have access to the funds deposited in your metamask browser extension. Transfers of Ether are passed directly from your Metamask account to a smart contract on the Ethereum network. By participating in the game you agree that the Game and its creators are not liable for any damages or loss of funds.


This game allows you to buy and collect digital assets. There is no guarantee that other players or anyone else will buy these assets from you. While some players speculate about their ability to resell their digital assets for a higher value in the future, there is no guarantee that another person will decide to buy your digital asset. If you choose to transfer ETH in exchange for the NFT in the Game, you must accept and understand the risk of potentially not being able to sell your NFT in the future. The Game is designed for collectors who choose to pay for the ownership of a digital product referred to as a NFT. If you choose to speculate over the future value and liquidity of your asset, you must do so at your own risk and not hold the creators of the Game or the NFT liable for any loss or damages. Play responsibly and do not spend more than you feel the digital asset is worth.


We have created unique, one-of-a-kind “NFTs” which are represented by ERC721 tokens on the Ethereum blockchain. These NFTs are mapped to real objects including but not limited to stars, galaxies, and nebulae. New NFTs will be released as we deem fit. NFTs may only be purchased with Ether. Any party may purchase any NFT that is on auction by being the high bidder at the time the auction ends, or by using the “buy now” function on an auction that has ended without any bids. If you are the owner of an NFT, you may choose to put it up for auction or on “buy now.” Any other party may purchase an NFT that you have put on auction or on “buy now.” These transactions are hard-coded into the blockchain and irrevocable: they cannot be undone by anyone, including the Game’s creators. Once any player bids on an auction, the auction cannot be canceled by anyone, including the original owner and Game’s creators.


Only the owner of an NFT may change the name of the NFT. This is hard-coded into the smart contract itself and nobody besides the owner can change the name of an NFT, not even the Game’s creators. Once the original NFT owner chooses to put the NFT up for auction, nobody (including the original owner) can change the name of the NFT, until the auction ends. If an owner chooses to rename an astronomical object NFT, all favorites and other badges or gildings associated with that NFT will be permanently lost and reset. Changing the name back does not restore these settings.


This Game requires that you utilize a compatible web browser that currently has a MetaMask browser extension installed. MetaMask is an electronic wallet created by a third party that allows you to purchase, store, and engage in transactions using Ethereum cryptocurrency. Any and all transactions that take place in the Game occur via the Ethereum blockchain. You understand that by using the Game, your Ethereum public address will be made visible to other users of the Game as well as third parties each and every time you engage in a transaction on the Game. We do not own and we do not control any of the following third-party products that may be used for the function of this Game: MetaMask, Coinbase, Google Chrome, Mozilla Firefox, Opera, Brave, or the Ethereum network. We do not own and we do not control any other third-party site, product or service that you may choose to access, visit, or use for the purpose of interacting with or using the Game. We will not be held liable, and are not liable, for the acts or omissions by any such third party, nor are we liable, or will we be held liable, for any damage that you may suffer as a result of interacting with or using any of the mentioned or unmentioned third parties. You are solely responsible for the safety and security of your MetaMask wallet and/or any other electronic wallet you utilize to interact with the Game.


If you choose to purchase any NFT on the Game, any and all transactions will be conducted through the Ethereum network directly to a smart contract on the blockchain, which is not controlled by the Game’s creators. We will not have any insight into or control over these payments or transactions, nor will we be able to reverse any transaction that occurs. We will have no liability to you or any other third party for any claims or damages that may occur due to any transaction that takes place on the Game and/or in regards to any of the NFTs that we have created. The Ethereum network requires that you pay a transaction fee, commonly known as “Gas,” for every transaction that occurs on the Ethereum network. Gas is intended to fund the hardware and software that runs the Ethereum network, as well as to prevent misuse and spam. If you choose to interact with the Game via our Site or without using the Game or our Site as a portal, you will still need to pay fee for every transaction you make on the Ethereum network. The smart contract keeps a 5% commission fee on every transaction conducted through it, in addition to the Gas charged by the Ethereum network. The creators of this Site and Game do not have access or control over these fees, as it is handled directly on the distributed blockchain network. We do not accept payments directly on our website.
