Smart contracts art and NFT experiments.
bio
0xG is a pseudonymous artist working between conceptual, digital art and the technical exploration of blockchain as a medium.
Their practice treats smart contracts as the artistic instrument, producing minimal, systems-driven works that exist directly on-chain, where often visual form serves underlying conceptual and computational structures.

"Truth Oracle" is an on-chain performance and critique of prediction markets, gambling and betting systems masked as truth oracles.
Participants minted free soulbound tokens representing Yes or No predictions. Every 3.5 days an external oracle revealed the outcome and eliminated the losing side. At the end a sole survivor would claim "Truth," a transferable 1/1.
The performance ended with no winners. Neither "Yes" nor "No" will ever exist, a result that turns the premise into the outcome.
After completion the oracle contract was verified, revealing an unprotected function called insider that allowed anyone to set the outcome of the next reveal and making the critique explicit in code.

"Untitled" is a conceptual collection of blank non-fungible tokens that raises a question about what people value: the token itself or a media link.
The collector is at a crossroads: embrace the blank token as a complete work, or link a wallet-signed 1/1 visual from the Catalog. That second action can read in two ways: it can reaffirm the false idea that NFTs are the visual artwork (when they are pointers), or assert that only the visual artwork matters in the end.
Most visual works 0xG creates are never minted and are only shared on social networks. The Catalog presents these works—each signed with a wallet, claimable once and permanently linkable to a token.

Released as part of the SuperRare Show called "Intimate Systems" (December 1st, 2025),
0xb88d4fde is a blockchain artwork shaped by cryptographic hashes of private messages, subtly recorded when the work is transferred.
This is achieved by using the optional data argument of safeTransferFromÂą as an invisible channel for human signals.
The collector generates a cryptographic hash of their private message off-chain and transfers the token with this data.
read more[+][-]
The new hash is combined with the current hashchain state `currentHash = keccak256(currentHash, newHash)`, deterministically reshaping the initial wireframe cube into a unique deformation that carries every past contribution².
Over time, this creates a parallel chain of subtle human signals moving through the system and the wireframe becomes a visual record of accumulated traces.
The process recalls a palimpsest: manuscripts once scraped and reused, leaving light remnants beneath the new writing.
The resulting form is simple rigid and geometric, yet layered with accumulated, intimate traces. To observers, it appears as a minimal cube; to participants, it is a structure shaped by presence.

The Pixel Prize is a hybrid grant-award that supports digital art critiquing censorship, privacy and blockchain's potential and flaws while giving winners exposure.
For the 2025 edition 0xG submitted a proposal about privacy as a right. The work introduces ownership through a cryptographic secret instead of a wallet address. Ownership becomes a matter of knowledge, not visibility.
After reviewing legal precedents in this area such as the Tornado Cash case 0xG withdrew the submission. That withdrawal became an act of self-censorship and arguably a stronger artwork than the original plan.
Full concept[+][-]
Untitled is an exploration of privacy, possession and the contradictions embedded in transparent systems. The work introduces a new model of ownership: an NFT bound not to a wallet address but to a cryptographic secret. Ownership becomes a matter of knowledge, not visibility.
In this system, collectors prove possession through zero-knowledge proofs, enabling ownership without revealing any link to their public identity. Transfer is performed privately: the current owner proves they know the existing secret without revealing it and transfers ownership to the new collector’s commitment. The transaction becomes just a silent handoff of meaning and control. This isn't just a novel mechanic, it's a prototype for how privacy could function in digital infrastructure.
Unlike traditional NFTs, which lean heavily on visibility and public signaling, this artwork can remain invisible - owned by the zero address and omitted from marketplaces entirely. Even when made visible, it rejects the idea that aesthetics must be tethered to external validation. The work lives in the mind of the collector and those who understand the privacy mechanism, not in the marketplace feed.
This approach directly confronts the tension between genuine privacy and societal expectations of transparency. Governments require identity verification for AML compliance; sellers must determine location for tax reporting. But this NFT architecture renders such tracing impractical - by design. What happens when what’s possible on-chain runs against how the world works off-chain? This project pushes that question into the open.
Collectors choose how anonymous they want to be. Some may transact directly from a wallet. Others may delegate operations to relayers, paymasters, mixers or even another human. The system doesn’t enforce anonymity, but it defends the right to choose it. Privacy here is a right, not a restriction.
At its core Untitled is infrastructure disguised as artwork. It’s not just a commentary - it’s a working prototype of what privacy-native digital art could be. A shift from public proof of taste to private stewardship of meaning. From signal to silence.
"Once a Human" is a series of reflections on AI from a technologist and artist imagining a future reality.
The works explore AI's controversies and impact today while projecting a world where the line between human and machine blurs.
Works are fully on-chain and released over time, ranging from visual pieces to conceptual explorations. Purely visual works require AI upscaling, mirroring the subjective nature of art interpretation.
Artworks details[+][-]
Visuals are generated using an older Stable Diffusion model (2022), with "Zero"—the first on-chain artwork by 0xG—as the foundation. Image-based pieces involve prompting, inpainting, parameter tuning and post-processing.
#1 Once a Human
This piece connects the collection to "Zero," the 2022 on-chain artwork by 0xG (still human!?). It can only be claimed by exchanging theZero token, which will then be permanently locked in the "Once a Human" contract.
#2 The Simplicity Paradox
A response to the claim that AI requires no skill. The deliberately simple artwork—something the artist could create by hand—highlights intention, authorship, and control in AI-assisted creation.
#3 Synthetic Nostalgia
Explores how AI mimics emotion—creating images that may move us, yet remain entirely meaningless to the machine that generated them.
#4 Once a Machine
A conceptual smart contract artwork in the "Once a Human" collection. It forms a recursive loop with its counterpart contract, creating a perpetual reversal that questions authorship, agency and whether we are observers or creators.

advanced alien intelligence. Each participant takes turns writing messages that are permanently stored on the Ethereum blockchain.
On the blockchain, identities are represented by unique addresses. Each user has an address and to verify ownership they also have a private key, which must remain secret. This private key allows them to sign messages, proving their identity and control over the address.
The address 0x0000000000000000000000000000000000000001 is unique because it isn’t owned by anyone. The concept suggests that an advanced intelligence, with technology far beyond ours, might be able to uncover the private key for this address and use it to send a message.
This artwork doesn’t dictate a specific visual for the exchange; instead, it hints at a conversation where messages can be displayed in custom fonts with decorative symbols, rather than standard Latin characters. This emphasizes how humans tend to expect art—or even alien communication—to conform to familiar forms, while this piece invites us to embrace the unknown and broaden our perspective.
"Contact" was submitted as an out of competition work to "CONTACT ATTEMPT – the 50th Anniversary of the Arecibo Message" organized by the Herbert W. Franke Foundation which recognised it a “special award”.

“Unlike” is 0xG's first artwork on the art-centric social network @rodeodotclub.
Unlike other posts collectors cannot mint it, yet 0xG forged 36526 editions.
For the next 100 years the work can be unliked once per day, a burn per day. The last person to unlike it acquires it as a 1/1.
By introducing the idea of unliking (via burning), 0xG inverts the common engagement model.
Instead of accumulating approval 0xG invites the audience to participate in a process of deliberate reduction that ultimately will set the 1/1 (metaphorically us) free.
Furthermore in true social network fashion the 'unlikes' are always available for purchase [info].

"Unseen" is a dynamic artwork 0xG created on KARBORN and SHL0MS's MOON:BEAM collection, the first ERC7160 on Base.
Photographs of asphalt under harsh sun hide unique artworks that appear only when the collector goes offline, a digital eclipse.
"Unseen" mirrors sun and eclipse with online and offline states. Since online time now dominates daily life its mechanism creates an opportunity to disconnect and zoom out.
Physical On-chain 1/1s
The project draws from Thomas Aquinas' metaphysical concept of Actus Essendi which defines and separates an entity's essence (its nature) from its existence (its actual being).
0xG relates this theory to generative art algorithms where the essence is symbolized by the artwork's generative nature and the static output, an image, embodies the reality and individuality of Actus Essendi.
Each piece in this collection features a physical print on glossy aluminum, accompanied by a redeemable NFT of the generative visual.
The collection takes a physical-first approach. Each print is a tangible snapshot of an on-chain generative visual that transforms at every resolution.
0xG's wallet signature on the back of each print allows collectors to transform the NFT's dynamic art into the static visual from that print and revisit the same philosophical tension.

"The Reveal" is an artwork that delves into the realm of human anticipation and speculation, a distinctive characteristic of the crypto art market.
Presented through a blind auction, "The Reveal" defies conventional expectations. The winning bidder unlocks a surprising revelation tied to the artwork's speculative nature and acquires it for free. This unconventional approach challenges traditional notions of value and transaction.

0xG co-authored a multi-metadata token standard that lets creators attach multiple URIs to a single token.
Some example use cases are listed below:
- A token represents a collection of (cycling) assets with individual metadata
- An on-chain history of revisions to token metadata
- Appending metadata with different aspect ratios so that it can be displayed properly on all screens
- Dynamic and evolving metadata
- Collaborative and multi-artist tokens
Marco Peyfuss, co-founder of TransientLabs, is co-author of this proposal.

"Degentralized Finance" is a unique digital artwork consisting of a single Non-Fungible Token that holds a single $PEPE coin. The owner of the artwork has the option to either keep the NFT or burn it to receive one $PEPE.
The artwork's statement implies that both the NFT and the $PEPE might or might not be deemed worthless: a symbolic gamble.

A statement on art, financialization and royalties.
Art should not be confined by speculation. So •duality tokens were free to mint, carry 0% royalties and remain transferable between wallets.
Yet any attempt to treat •duality as a trading asset fails because non-custodial marketplaces and operators cannot move tokens to finalize a sale.
To unlock and sell a •duality token traders must pay 0.5Ξ upfront, an enforced royalty.
Token #1 was airdropped to the top Blur.io trader.
0xG wants to leave you with an interesting interpretation of the art:
This is a statement about duality of purpose.For a time, two entities run alongside each other, in parallel. They seemingly share a direction.But, do the contrasting hues represent a difference of intent? And, is the grey path bound to the white?— NonFungii

In November 2022 0xG anticipated open editions would flood the market and created one that never ends but cannot be owned past the next mint.
An infinite edition – an ephemeral creation that exists only until the next one is minted.
The contract remembers the collector's burned token id.
The collector is effectively left with a soulbound Non-Fungible Token stripped of visual and economic incentives.
N. is a fake ERC721 that misleads marketplaces by making them think it supports the ERC721 standard. Furthermore the contract uses events to deceive marketplaces and make them think that tokens are being burnt and minted.

Y. is the closing act of N.
Y. explores connection, individualism vs collectivism, many vs one and objective vs subject.
During NFT Paris 2023 a number of collectors and strangers connected and shared the free mint experience.
It consists of 24 on-chain frames with connecting lines that range from none to full.
All 24 Y. artworks stand alone as finished one-of-ones. The mechanism still allows recombination, a rare event that would require unanimous agreement.
“This piece holds sentimental value for me as a shard. Sometimes there is beauty in the imperfect, the unfinished.” – Y. #4's owner
When combined, the 24 tokens become a single animated on-chain artwork and the contract forges the only permanent N., ever.
Will collectors connect and combine the tokens?
Will any individual interest prevail?
Will N. ever exist?

Collectors received a signed JPEG that carries 0xG's wallet signature through steganography.
Signatures are one of the most important components of blockchain technology and can be verified off and on-chain.
Later it was revealed that the signature in the JPEG is a mint pass. This is the first visual allowlist of its kind and collectors who are in it can then mint the token.
0xG wants to make a clear distinction between the visual-centric creation and blockchain-centric one. The post-mint experience wants to show the power of the blockchain medium and what it enables beyond image tokenization.
Every October 31 Paradigm Shift tokens move to the Burn Address (0xdEaD). Collectors then have 24 hours to revive them or leave them dead and locked for one year.
Therefore the collection's supply is dynamic and different every year.
We can call the alive ones Non-Forgotten Tokens.
Meaning and additional mechanisms in the collection are to be discovered.

PixelChain 256 is an on-chain pixel art project.
Using the PixelChain app invited creators could draw their 1/1 pixel art which would then be encoded in the token id upon minting.
0xG bypassed the app and minted token id 1 directly from the contract, drawing with code as a deliberate hack.

Perpetual rethinks editions with an unlock mechanism that gives collectors direct control over visual updates.
The creator sets the supply for the current and future editions upfront.
New editions can vary in size and can only be acquired by burning an unlocked piece from another edition in the same collection.
Every token starts with the artwork that is meant to be collected. The collector has the option to unlock the token to enable burning for a new piece. When unlocked, the token visual changes.
Over time repeated burns and releases can turn a Perpetual collection into a set of 1/1s.
The first edition in the Perpetual collection is called "The Fork in The Road" and was acquired by burning a previous 0xG creation.

Locked Metadata
Perpetual also defines a metadata model that gives collectors full control while still letting creators publish updates.
At mint time each token receives a metadata url the creator cannot overwrite. The creator can update a master copy in the contract and collectors can opt in to the latest version.
"The Update" is a 2/2 edition that demonstrates the concept. The creator offered the opportunity to update "The Fork in The Road" for a limited time and two collectors took the update:

“Fearless”, the collector edition, is the first 1/1 in the Perpetual collection.
Fearless is about big price tags on NFTs which is what many people pay attention to.
The original concept set a 300 ETH mint that refunded thefearless collector in the same transaction.
However, the mechanism was never deployed because it could be interpreted as price manipulation.
Instead the contract requires a wallet balance of at least 300 ETH in order to be able to acquire the work for free.
The NFT ended up being minted 2 minutes after the announcement.

"Fearless" reflects the constant threat of exploitation in web3.

"Owned" bends NFT ownership rules with a smart contract that lets owners lend tokens.
Three NFTs share one visual and vary only by ownership status. They show how a collector can hold an NFT without owning or controlling it.
"Owned" critiques ownership in NFT culture and current exhibition habits. Works are often right-click saved and displayed without the original. Should exhibitions, museums and galleries hold the original they present? What is being exhibited otherwise?

"blink" uses a pre-trained machine learning model to detect the collector's blink and pause the visual's animation.
It opens a window onto a future where machines might end up deciding whether we are human or not.
An open edition that will never exist.
Participants could "blink and screenshot it." The three most appreciated screenshots were minted as NFTs and given to the "spectators."
