How to trade NFTs across blockchains!
Emblem Vaults are ERC721 or ERC1155 NFTs that are used to effectively store and exchange assets across a range of different blockchains without the use of bridging.
In this way, these NFT “vaults” act as transferable multi-asset wallets that are able to contain both fungible and non-fungible tokens. They can also facilitate activity across chains regardless of whether they’re compatible with the Ethereum Virtual Machine (EVM) or not.
First unveiled in September 2020, Emblem Vaults have since become the leading solution for trading historical NFTs from non-EVM chains like Bitcoin and Dogecoin on Ethereum’s contemporary NFT marketplaces, e.g. OpenSea. Notably, 30,000 unique vaults have been created to date, from which over Ξ40,000 worth of trading volume has been facilitated since December 2022.
How it works
“Technically speaking, an Emblem Vault is an NFT. We describe it as if that NFT ‘contains’ a whole wallet full of assets, like a piggy bank, and then that entire piggy bank can get passed around as a single asset.” — What IS An Emblem Vault?
The NFT that represents a particular vault includes access to a series of blockchain addresses that have been created from a single, unique seed. During the “unclaimed” vault state anyone is able to send assets, like NFTs, to these addresses but no one can withdraw the assets because the underlying private keys remain totally hidden at this point.
Accordingly, a vault NFT can be transferred or traded with its unclaimed contents inside. After purchase, a buyer is able to unlock the private keys, access the contents inside, and then move the assets into any other wallets that they wish. Upon being claimed, vault NFTs become non-transferable so they can’t be used by another person.
When you purchase a vault NFT, you purchase the ability to burn that vault and thereafter take control of its associated private keys, which are numbered at 20 per vault currently. That’s because right now Emblem Vaults support 20 blockchain integrations, which are as follows:
While vaulting assets with Emblem Vaults is generally the same process across chains, vaulting Ordinals-style Bitcoin NFTs does have unique steps you need to be aware of. A great guide to get you up to speed on the nuances of this process comes via historical NFT collector obi:

The big picture
Back in February 2021, a PEPECASH card became the first Bitcoin-based NFT to sell on Ethereum through an Emblem Vault. Fast forward two years later and now this same system is facilitating hundreds if not thousands of daily Bitcoin NFT transactions on OpenSea. This all, of course, comes as the current Bitcoin NFT boom is barely one month old.
As this new NFT scene continues to grow, Emblem’s activity levels stand to rise for the foreseeable future as this system both supports this growth and shows more people they can take their NFT storage and trading activities cross-chain in fairly straightforward fashion.
