How It Works
Your tattoo, on Ethereum — what that means, and how to prove it.
How it works, in three steps
- Step 1
Upload
Pick a photo of your tattoo. We fingerprint it (SHA-256) and store it.
- Step 2
Pay once
A single payment — a one-time fee in ETH. No subscription, no recurring fee.
- Step 3
Minted forever
Your tattoo becomes an ERC-721 token that lands in your own wallet, pointing at your image.
What “forever” actually means
Once minted, your tattoo is enshrined on Ethereum — owned by you, verifiable by anyone, for as long as Ethereum itself exists. Not on our servers. On a public blockchain no single company controls — including us.
For the technically curious
On-chain is immutable. Your token, your ownership record, and the reference to your image live on Ethereum, replicated across thousands of nodes. No one can delete or alter them — not even enshrine.tattoo.
The image lives on IPFS, by its content hash. It’s pinned via Pinata, but because it’s addressed by its own bytes it isn’t tied to our servers — you or anyone can re-pin the exact same image. An IPFS file stays retrievable as long as someone keeps it pinned; we pin it, and content-addressing means you’re never locked to us.
If enshrine.tattoo disappeared tomorrow, your token and ownership are untouched on Ethereum, and your image can be re-pinned by anyone from its hash.
Don’t trust us — verify it yourself
It’s a real ERC-721 token you hold in your own wallet — not an account on our site. Everything below is public and checkable.
- Verified source. The contract’s Solidity source is published and verified on Etherscan — what you see above is exactly what runs on-chain.
- Owner-limited upgrades (UUPS). The contract can be upgraded to fix bugs, but only by its owner, and your token and ownership are never affected.
