Fossil

Launch coins on Robinhood Chain and fossilize them onchain. Art, audio and pages stored as contract bytecode, sealed by SHA-256. Coins that never decay.

Launch coins on Robinhood Chain and preserve images, audio, self-contained HTML or plain text as contract bytecode. Add metadata and links, then seal each specimen with SHA-256.

Two fossils. One combined position.

Gallery Duo lets you pair specimens, compare them side by side and see where their combined $FOSSIL conviction would rank on the wall.

Build a duo and share it directly from the gallery. 🦴

ON CHAIN SEAL + DNA

Every FOSSIL carries its own on-chain identity.

The specimen page exposes its media type, byte size, SHA-256 digest, sealed block and storage pointers, alongside a unique DNA fingerprint generated from its history.

The proof is part of the specimen. 🦖

FOSSIL just got personal. 🦴

Creator Profiles bring every specimen you have launched or stamped into one on-chain portfolio—complete with aged DNA fingerprints, combined market stats and sealed status.

Open any specimen, click Creator and see who is behind it.

Don’t trust the server. Verify the specimen.

FOSSIL reconstructs the media from contract bytecode, computes its SHA-256 and compares it with the digest sealed onchain.

If the bytes change, the hash does too. An exact match proves the specimen is intact.

SAME AGE, DIFFERENT EROSION

Same block age. Completely different weathering.

Each FOSSIL address begins with its own generative fingerprint, then develops a unique pattern of patina, fractures and mineral deposits as blocks pass.

No two look alike. No two age alike. 🦴

BLOCK AGE SCRUB

Every block leaves a mark. 🦴

Scrub through a FOSSIL specimen’s onchain lifetime—from a clean new stamp to deep patina, mineral buildup, fractures and faded color.

The address preserves its identity. Time changes its surface.

[Fossil @fossil_rh]

Every FOSSIL specimen now ages onchain.

Fresh stamps begin clean and bright. As block age accumulates, each develops its own patina, mineral deposits, fractures and faded color.

The identity stays deterministic. The weathering becomes uniquely its own.

No two look alike. No two age alike.

[Fossil @fossil_rh]

Your FOSSIL fingerprint is deterministic.

Open it today, return tomorrow or find it from another browser the same 20-byte address always rebuilds the same face. No stored image is required.

20 bytes in. One identity out.

https://t.co/fuWTaktJHp

[Fossil @fossil_rh]

Same chain. Different addresses. Completely different faces.

Every ring, ray, node and color is derived from the coin’s 20 byte address giving every FOSSIL its own recognizable onchain identity. 🦴

[Fossil @fossil_rh]

Every FOSSIL coin now has a face. 🦴

Paste any 20-byte token address and FOSSIL turns it into one deterministic generative fingerprint. No upload. No random seed. Just the address.

NEW on FOSSIL: Prophecies 🔮

Leave a time sealed message on any specimen page. Your prediction lives forever in a shareable link.

Connect your wallet to stamp your $FOSSIL tier on the prophecy. No account needed just words, a timestamp, and conviction.

Every prophecy = its own URL.
Every URL = its own receipt.

FOSSIL isn't just for creators anymore.

Anyone can now nominate a coin to be fossilized:

Find an unstamped coin on https://t.co/SE2chNN6Nc
Hit "Nominate"
A tweet goes out calling on the creator to seal it
The community decides what gets preserved. The creator seals it. The chain keeps it forever.

[Fossil @fossil_rh]

https://t.co/IvwaaS9A45 just got a front page upgrade.

Three sealed fossils greet you the moment you land with tier badges showing who's climbing the leaderboard.

No static text. Living specimens.
