Fully On-Chain SVG NFTs — Part 1: Basic SVG Rendering

First part of a hands-on series on generating SVG art from Solidity itself: writing a contract that emits SVG strings, then compiling and testing it with Foundry so the output can be dumped to a file and iterated on. ERC-721 wiring is left to later parts.

On-Chain NFTs Timeline v1

A timeline for the nerds & boundary-pushers in the NFT space: on-chain NFTs from 2011 onwards across Namecoin, Bitcoin and Ethereum, marking which store the media itself on-chain and which generate it in-chain.

Souls of Immortal NFTs

Classifying fully on-chain non-fungible tokens

“On Chain”, “Generative” “Art”?

What “on-chain” and “generative” actually mean, read off the contracts of Cryptopunks, MoonCats, Autoglyphs and Loot — and why permanence rests on surviving standards and context as much as on stored bytes.

3 different ways to make on-chain generated NFTs

Three ways to generate NFT artwork inside the contract itself rather than serving it from a server, compared side by side.

How to create on-chain NFTs

Today I will show you the process of creating NFTs purely on-chain. This is a simple yet powerful example. With this knowledge, you will be able to extend on this and create creative solutions for on-chain SVG NFTs. Hope you enjoy the video.

Decoding Forgotten Runes Wizard’s Cult from on-chain data

Reconstructing the Wizard's Cult artwork straight from Ethereum, and the TypeScript tooling needed to decode what the contract stores.

Flavours of On-Chain SVG NFTs on Ethereum

The different ways projects put SVG art on Ethereum — layering pre-stored traits, generating from a seed — and the gas, permanence and encoding tradeoffs each choice carries.

0xmons v2 Cthulhu: On-chain Encoding

Why 0xmons moved its artwork on-chain, the encoding that makes it fit inside a contract, and how to encode your own.

Ethereum NFT token-to-asset mappings are off-chain and nobody cares

Hashmasks records a provenance hash on-chain but leaves the token → image formula on its own website, so what a token actually depicts rests on information the team can still change — with two ways to move that mapping into the contract instead.

On-Chain Artwork NFTs

What NFT permanence actually requires, contrasting artwork held off-chain with work stored in the contract itself, through CryptoPunks and Autoglyphs.

The broken promises of NFT Art

NFT’s are often sold with the premise of permanence, but is the reality that most are destined to the trash heap of history?

Autoglyphs, Generative Art Born On The Blockchain

An interview with Larva Labs' Matt Hall and John Watkinson on Autoglyphs, whose generator and output both live on Ethereum, and the constraints behind the 512-piece edition.
