TL;DR
Non-fungible tokens (NFTs) are in high demand all across the blockchain and DeFi ecosystems. There’s a lot of information on the NFT topic already, but we don’t often discuss custodianship. Who actually has full control of the NFT you’ve just created or purchased? It may be that you have less custody of your NFT than you think.
This concept might be familiar if you’ve already looked into wallets and cryptocurrencies. In fact, having custody of your NFT or letting someone else hold it are both valid options. It all depends on what you’re looking for and the kind of responsibility you want to have.
The main ways you’ll encounter custodial and non-custodial NFTs are when choosing a wallet and the platforms you use to trade or create NFTs.
A custodial crypto wallet doesn’t give you full control of your private keys. A third party (such as an exchange or custodial wallet service provider) will store your assets for you. You will not be able to access your private key yourself, but this isn’t necessarily a bad thing. It all depends on your needs.
However, don’t forget that in this case, a third party has custody over your funds. Your crypto will only be as safe as the custodian keeps it. That’s why it’s important to choose a reliable exchange or service provider.
A non-custodial crypto wallet is a wallet where only the holder possesses and controls the private keys. For users who want more control over their funds, non-custodial wallets are the best option.
You can use both custodial and non-custodial wallets to store your crypto art or other NFTs. However, make sure the wallet you use supports the type of NFT you want to keep. NFTs can exist on different blockchains, and even on an individual blockchain, there can be various kinds of token standards. Each standard has different characteristics and rules that define how the tokens are created and used.
The most common token standards are:
-
Binance Smart Chain: BEP-721, BEP-1155
If you plan on storing an NFT in either a custodial wallet (like on a cryptocurrency exchange) or a non-custodial wallet, check first the NFT’s token standard. With this information, make sure your wallet supports the blockchain and token standard of your digital art.
MetaMask, Trust Wallet, and MathWallet are all non-custodial wallets that accept the most common NFTs you’re likely to encounter. But when interacting with a centralized exchange, you’ll use a custodial wallet. Your best option is to check your exchange’s FAQ or website for more detailed information on the NFTs they accept.
Decentralized platforms (non-custodial)
NFT marketplaces (custodial)
An NFT marketplace acts as a custodian during the purchasing process. If you want to bid on an auction, you will need to send your funds to the platform to hold them in escrow. Once you have purchased your NFT, you can either keep it in their custodial wallet or withdraw it to another wallet.
Decentralized platforms (non-custodial)
After minting, your assets will be stored on-chain and cannot be altered. If you wish, you may put your NFTs up for sale. Featured by Binance currently supports two sales methods for its secondary marketplace: fixed-price sales and English auction.
As soon as the sales are completed, your NFTs will be distributed to the buyers. The proceeds of the sales will be transferred from the buyers’ wallets to yours. The process is automated and secured by the rules of smart contracts.
NFT marketplaces (custodial)
To sell your NFT on a custodial marketplace, you’ll need to deposit it into the platform you’re using. Make sure that the platform accepts the type of NFT you would like to sell. If you’re not careful here, you can easily lose your NFTs by sending them to an incompatible platform. Each marketplace will have different options for sales, such as fixed price sales or auctions.
Once you have successfully sold your NFT, the marketplace will automatically transfer it to the new owner. Your funds will either be sent directly to your external wallet or left on the platform for you to withdraw.
A custodial service provides a simple way to match NFT buyers and sellers that is easy for newcomers to use. There’s no need to worry about losing your key, which is a relief even for more experienced users. Interfaces are generally user-friendly, and the whole process is more forgiving when it comes to making mistakes. If a problem occurs, the platform should have support in place to help.
Non-custodial NFT platforms provide much greater control throughout the transaction process. Trading NFTs directly from your wallet without an intermediary provides cheaper fees and more privacy. However, these factors are more dependent on the network you’re using. If you value privacy, there is no need for KYC checks so you can trade anonymously. All you need is a wallet to get started.
There are a few downsides to non-custodial control. For new users who aren’t so familiar with wallets, non-custodial options can be less user-friendly and convenient than custodial ones. Fortunately, however, service providers like Tor.us are making dapps a lot easier to use.
