👉 CryptoSkulls are the first-ever 10k PFP collection using the ERC-721 standard.

⚡️⚡️⚡️

Everyone knows that CryptoSkulls are the second 10k PFP NFT collection in the world, following CryptoPunks.

But here’s the key difference: CryptoPunks are not ERC-721 tokens, while CryptoSkulls are.

ERC-721 is the first official standard for creating non-fungible tokens (NFTs) on Ethereum — the foundation of today’s NFT ecosystem.

The consequences of this fact — including how the market values CryptoSkulls — are only a matter of time.
