Your wallet is the artist.
Every transfer is a new brushstroke.


Heraldia is a fully on-chain generative experimental NFT project by ab83 — where ancient heraldic principles meet pixel art. Coats of arms, reborn on Ethereum.

Two hashes shape every token. A static hash defines your emblem — minted once, yours forever, no one can change it. A dynamic hash responds to your wallet — pass the token to a new owner and the entire composition transforms. New colors. New patterns. New history.

Pure Solidity. No IPFS. No servers. The code is the art. Ethereum forever.

Heraldia

Your art. Your history. On-chain forever.

Generative
Every token is unique. Pattern, emblem, colors — all derived from your wallet address and a stored static hash.
Dynamic
Art redraws with every transfer. New owner — new coat of arms. Every transfer makes new history.
100% On-chain
No IPFS. No servers. No external scripts or libraries. 100% Solidity. Lives on Ethereum forever.
Heraldia never stops creating.
Every transfer is a new genesis — a new coat of arms, computed entirely on-chain. No two owners see the same composition.
The collection evolves forever, as long as tokens move between wallets. Infinite heraldry. Eternal code.

Token history.

From mint, every transfer shapes a token's history — recorded on-chain forever. HIR (Heraldia Intelligence Rarity) engine decodes that data and reveals the full story. Not just trait-based rarity — it tracks every transfer, analyses every combination and rewards each token with badges.

Heraldia
STATIC HASH
Born at mint. Immutable forever. This hash defines your emblem — the soul of your token. No transfer can change it. No owner can alter it. It passes from hand to hand, untouched.
Heraldia
DYNAMIC HASH
Your wallet writes the art. This hash is computed from the owner's address — it shapes the colors, the background, the pattern around your emblem. Every new owner creates a completely new composition. Same emblem, different world.

FAQ.

01.
How many tokens in the collection?↓
10,000 unique tokens.
02.
Can I choose a specific emblem?↓
No. The emblem geometry is randomly generated at the moment of mint — it cannot be predicted or chosen in advance. Every mint is unique.
03.
Can I see what my token will look like before minting?↓
No. The emblem is generated at mint. However, colors and patterns always depend on your wallet address.
04.
What happens to my token if I sell or transfer it?↓
The emblem stays the same, but the entire composition — colors, background, patterns — completely changes based on the new owner's wallet address. Every owner gets a unique version of the same coat of arms.
05.
Where are the metadata and images stored?↓
Everything is stored directly on the Ethereum blockchain. No external servers, no IPFS, no APIs. Solidity code computes the SVG inside the smart contract. Nothing to break, nothing to disappear.
06.
Does it cost gas to change the art?↓
No. The visual change happens automatically on any transfer. The smart contract reads the new owner's address and computes a new composition. No additional transactions required.
07.
Can I view the smart contract code?↓
Yes. All contracts are open source and verified on Etherscan. Full transparency is part of the project's philosophy.

08.
What makes this project different?↓
Heraldia explores the boundary between permanence and change. One token exists in an infinite number of visual states, but its core — the emblem — remains unchanged forever. One hash stored. One hash computed. Art lives forever.
