Users do not need an external (or “non-custodial”) wallet to participate in the purchase of an Autograph NFT. However, in order to “mint” the NFT, you must link your own external wallet to your Autograph.io account. Today, Autograph supports the following external wallet types: Metamask, Coinbase, Wallet Connect.
Linking an external wallet (and minting the NFT) is not a requirement for being eligible to redeem benefits / experiences associated with an NFT. However, once an NFT is minted, the external (or “non-custodial”) wallet holding the NFT must remain linked to the user’s profile on Autograph.io to maintain eligibility for redeemable benefits / experiences.
For more information on how to link an external (non-custodial) wallet, please reference Autograph’s blog post on Wallet Linking Instructions.
