How to mint music NFTs 🎼

Can you carry a tune? How about carrying it on-chain, then!

Metaversal is a Bankless newsletter for weekly level-ups on NFTs, virtual worlds, & collectibles

Dear Bankless Nation,

I have a lot of musician friends.

That said, I wanted to write the music minting guide I’d want to read personally if I was just starting out with NFTs. So this is that guide!

Note that I’ll mention some possibilities on a few NFT-friendly chains, but I’m going to focus mainly on Ethereum because it’s where the vast majority of the action is at and provides the best guarantees for artists going forward. 

Here’s the why, the how, and other helpful stuff 👇💽

Why mint music NFTs?

Independent artists can make label money by themselves in the NFT space, essentially removing the risk of being undervalued/cheated/reliant on/by corporate entities.” — Freddy Got Magic, an artist, producer, and audio engineer

Ethereum is community-run neutral public infrastructure for apps, media, and money. 

In the context of artists, this means creatives can use Ethereum and NFTs to interact with and distribute media (e.g. album art, lyrics, music videos, 1/1 singles, EPs) to their fans directly and on their own terms. 

This direct-to-user approach allows musicians to capitalize on their creations without having to deal with the rent-seeking middleman woes that plague the traditional music industry and corporate music services. 

Additionally, the NFT approach also provides new opportunities for artists, like automated and self-determined royalties, and new experiences for audiences. 

Is Ethereum the best platform for NFTs?

Ethereum is the leading smart contract platform and for that reason has become the favored blockchain for NFTs (and decentralized payments, and decentralized finance, etc.). In short, Ethereum offers:

  • 🛡️ The best security guarantees (Ethereum is the most decentralized and secure smart contract platform by far, meaning it can secure your NFTs indefinitely)

  • 🤝 The largest NFT community (Ethereum has the largest NFT community and thus is currently the best place to make new friends and connect with new fans)

  • 🌊 The best liquidity (Ethereum has the most NFT markets and NFT activity)

However, there are also other blockchains where musicians are currently experimenting with NFTs, too. These alternative chains may not offer the superior long-term guarantees of Ethereum, but if you research and approach the tradeoffs carefully there are some projects you might consider trying. Two that I’ve personally tested:

  • Hic et Nunc — Indie NFT art platform built on Tezos that supports MP3s, MP4s, WAVs. 

  • Mintbase — NFT platform built on NEAR Protocol that supports MP3s, MP4s.

Wait, are NFTs bad for the environment?

It’s no stretch to say that blockchains and NFTs are popularly misunderstood. So was the internet when it first arrived. Unfortunately, these misunderstandings have recently led some people to grossly mischaracterize the environmental impact of NFTs.  

In any case, just know this: the future of blockchain and NFTs is via environmentally-friendly proof of stake systems. PoS chains are considered “green” because they use many orders of magnitude less energy than non-PoS projects like Bitcoin. Ethereum is on the verge of completely transitioning to PoS, and there are many green Ethereum scaling solutions that will prove increasingly powerful to creatives over time. 

Additionally, I argue on utilitarian grounds that Ethereum, NFTs, etc. should be pursued for the good of the environment going forward. Why? Because NFTs provide a digital, direct-to-user distribution avenue that can de-physicalize or provide powerful alternatives to tremendous swathes of physical activity, e.g. global CD distributions. And NFTs can and will do so as powered by green blockchains and green scaling solutions.

What you’ll need to start

In the context of Ethereum, you’re going to need two things at minimum to get started minting music NFTs:

  1. An Ethereum browser wallet (MetaMask is the most widely used; other options include WalletConnect and Coinbase Wallet)

  2. Some ETH, Ethereum’s native currency (to pay “gas,” a network fee, for mint transactions on Ethereum, that is unless you’re doing lazy minting where you don’t have to pay anything up front)

If you’re interested in acquiring your first ETH, check out this Where to buy ETH guide that lets you search for resources by country.

Where to mint music NFTs

There are a variety of different NFT platforms available today that musicians can consider minting through. Below, I’ll walk through the top ones that I’m aware of. 

Do note that some NFT platforms, like Foundation, KnownOrigin, and Nifty Gateway, support MP4s. This opens up interesting audio-visual opportunities for musicians. For the purposes of this article, though, I’m going to focus on platforms that already support popular music file types like MP3 and WAV. 

Async Music 

Description: Async Music is the programmable music arm of Async Art, Ethereum’s premier platform for “dynamic [and] interactive” NFTs.

Socials: Website | Twitter | Discord 

Currently invite-only: Yes (application form here)

Supported file types: MP3

The main idea:

This is music with the ability to change its composition. It may sound different each time you come back to listen. This is achieved by breaking down a song into separate layers called Stems. Each Stem has multiple Variants for its new owner to choose from. In this way, a single Async Music track contains many unique combinations of sounds.” — Async Art

Socials: Website | Twitter | Discord 

Currently invite-only: Yes (application form here)

Supported file types: MP3

The main idea:

We're reimagining how artists share, distribute, and capture the value around their music using single edition digital records. Catalog records are unique, one-of-one tokens that exist on the internet forever, beyond the limits of our platform, and represent the canonical version of an artists’ work online.” — Catalog

NFTs allows you to create, own, and sell original digital creations: artworks, music, in-game assets, domain names, and many more (we'll get to that!). When created as NFT, the original item becomes scarce and impossible to fake: it can now be owned by someone and invested in.” — Rarible’s docs

Honorable mention: Audius

Audius is a decentralized music sharing protocol. Think a community- and artist-owned Spotify except built on Ethereum + Solana. Audius isn’t an NFT minting platform, though it does offer Audius Collectibles, a feature where musicians can display their NFTs on their Audius profile.
