Magic Eden, the marketplace for immutable collectibles, has announced the launch of its latest supported chain - Bitcoin.

"With great respect to the origins of web3, we are thrilled to announce the launch of our latest supported chain on Magic Eden - Bitcoin," the statement read. "As the most original, decentralized, and biggest blockchain in the world, Bitcoin represents an opportunity to build a unique marketplace where folks can trade true, immutable collectibles, something that was inconceivable until the release of Ordinal Theory."

The project has already built marketplaces on Solana, Polygon, and is re-planning a more concerted entry into Ethereum.

Magic Eden also plans to open source key pieces of the marketplace infrastructure soon in order to help push the ordinal ecosystem forward.

Full thread:

2/ We're continuing our multi-chain journey supporting the strongest communities of creators & collectors. Take a dive into the exciting world of Ordinals w/ our familiar user experience and a non-custodial BTC wallet from our partners @xverseApp, @hirowallet, or @unisat_wallet

3/ Why Bitcoin? Ordinal digital artifacts exist on-chain, never off-chain, and are totally immutable, meaning they cannot be altered in any way.

Add the security aspect of BTC & the decentralization of its nodes, and you get the ultimate home for true digital collectibles.

4/ Bitcoin developers have worked to bring collectibles to the number one blockchain for nearly a decade. Now that they're here, we want to bring our strengths to this brand-new ecosystem and grow it together with pioneers like @rodarmor , @p0stc4p0n3, @domodata and many others.

5/ The Magic Eden experience on Ordinals features a fully permissionless, non-custodial marketplace for secondaries that utilizes partially signed Bitcoin transactions (PSBT), as the core technology, instead of smart contracts.

6/ PSBT infrastructure is important to enable permissionless swaps.

In order to do our part in pushing the Ordinals ecosystem forward, we'll be OPEN SOURCING our PSBT signing library to help builders new to the space. 

7/ On royalties: we spent a lot of time on how to handle royalties in this new ecosystem where there is very little tooling and no secure and trustless enforcement solutions.

With no standard today, we have decided to launch on Bitcoin without royalty support for now.

8/ We believe that this is most in-line with the ethos of the ecosystem, and despite this, we are actively looking into the development of an on-chain, permissionless royalty standard and are committed to working with creators and the greater community.
