Wallet Invaders are fully on-chain (or better be called "fully in-chain"), EVM generated. This means that the invader images, traits, and metadata are all generated on-chain, from Solidity smart contracts (imgages are SVG content). No IPFS, no external storage, no off-chain processing. Everything is 100% on-chain.

This means the invader images and all metadata can be generated directly from the Base blockchain forever (as long Base is around)!

The contract is verified by onchainchecker.xyz (opens in a new tab) - de-facto the standard for on-chain verification.

With a perfect score 5 of 5!
