How Vampchain works

Grab any ERC20 on Base, Ethereum, or Robinhood Chain — yours, a friend's, that coin someone aped into at 3am — and it becomes the native gas of its own real chain. Real RPC, real blocks, real transactions, alive in under a minute.

Every chain gets its own home on scan.vampchain.com too — live blocks, transactions, address lookups, and contract verification. A real explorer for a real chain, not a toy.

Keeping it alive costs a little blood — a small weekly fee, low enough to try something without swearing a blood oath. Anyone can top it up, not just the creator, and funding drains linearly and publicly: nobody, including us, can ever charge you for time you haven't used yet.

$10.00/week, two weeks minimum to start ($20.00) — or fund as many weeks as you like. Exact numbers, and the rare cases we'd change them, live in the terms.

Every transaction on your chain spills a little blood — gas fees. We catch every drop and split it three ways, automatically, forever: a third to you, a third to the protocol, a third back into keeping the chain alive.

This is on top of the fee, not instead of it — the fee covers our infrastructure; the split is the ongoing reward for growing a chain.

Bridging into an obscure chain is a real risk — not losing a trade, but the chain flatlining. That's what the runway third above is for: it goes to a wallet kept separate from the protocol's own share, earmarked for conversion back into that chain's funding on a best-effort basis. The more a chain gets used, the longer it stays alive. Every chain page shows exactly how much that wallet is holding and how much it's actually delivered — live and checkable, not just promised.

We also track, and publicly show, how much real gas every wallet has spent per chain — we call it blood given. No payout, just a leaderboard: credit for whoever's actually keeping a chain's heart beating. Check any chain's page for its top donors.

A vampchain doesn't just die the second its runway hits zero. Here's exactly what happens:

1. 01

   Alive

   Fully funded and running — deposits, minting, top-ups, everything works. Anyone can extend the runway; that's the public anti-rug mechanism.

2. 02

   Running on fumes

   Paid runway hits zero. The chain doesn't shut off — it moves into a one-week grace period.

3. 03

   Grace period (7 days)

   Stays fully open for a week — same as step 01. A real rescue window: top it up and it's back to normal, nothing lost.

4. 04

   Snapshot

   If grace expires unfunded, we take one last read of every real balance — every wallet, every token — and publish it on the home chain as a Merkle root. Infrastructure is torn down right after.

5. 05

   Claim window (30 days)

   Anyone with funds on the chain can look up their wallet and withdraw exactly what the snapshot shows, proven against that root.

6. 06

   Gone for good

   Whatever's still unclaimed after 30 days goes to the protocol. This chain doesn't come back — but a new one for the same token can always rise from scratch.

Chain torn down? Look up your wallet to see if you have anything to claim.

• Unaudited, experimental software run by a small team — not a foundation, not a DAO.
• The bridge is secured by a single relayer key we control, not a light client or multisig. If that key is compromised, bridged funds are at risk.
• The business could shut down, and any chain can be frozen or torn down — the grace period and snapshot process are best-effort, not a guarantee.
• Funds in other protocols on top of a vampchain (DEXs, lending, anything you build there) carry extra risk if that chain is frozen or torn down.
• Bugs are a real possibility in software this new. Treat everything you bridge in as money you could lose entirely.
