NFTs with
tokens inside
Every elhashcash NFT holds a fixed amount of an Elysium launch token, locked in an on-chain vault. Holders earn a share of the coin's creator fees, up to 75%, set by the coin's creator. Swap the NFT back for its tokens whenever you want.
// convert
Token ⇄ NFT
Lock tokens and get NFTs. Burn NFTs and get the tokens back. Same amount both ways, every time.
- Token → NFT: every 10,000,000 tokens you lock become one NFT. Anything left over stays in your wallet.
- NFT → Token: burn an NFT and receive exactly 10,000,000 tokens, plus any fee rewards it hasn't claimed.
- The tokens wait in the on-chain vault while you hold the NFT. Nobody else can move them.

// the concept
A token you can hold like a collectible
Meme coins are liquid but forgettable. NFTs are collectible, but usually backed by nothing. elhashcash puts the two together: every NFT is a sealed container holding a real, fixed amount of a coin.
Real backing. Every NFT is matched by tokens sitting in a vault that only the contract controls. You can check the numbers on-chain at any time.
Same amount, every NFT. Each collection fixes how many tokens one NFT holds, forever. NFT #1 and NFT #10,000 hold exactly the same.
It earns. The coin's creator sets a share of its creator fees for NFT holders, up to 75%, split equally per NFT and paid in HYPE.

The math, live
Real contract maths, running in your browser.
// lock one NFT costForTokens(10_000_000n * 10n**6n, newCurve(), fees).total
// inflow = 4 HYPE of creator fees holders = inflow * MAX_HOLDERS_SHARE_BPS / 10_000n team = inflow * PLATFORM_SHARE_BPS / 10_000n
// 4 NFTs share the holders' part s = syncRewards(zero, holders, 0n, 4n) pendingLamports(s, 0n)
// NFT #5 mints late, then 2 HYPE arrives (E = 1 HYPE) s2 = syncRewards(s, holders + 2n * E, 0n, 5n) pendingLamports(s2, s.accPerNft)
// how it works
In, earn, out
One transaction buys exactly the tokens one NFT needs on Elysium launch, locks them in the vault and mints your NFT. If any part fails, nothing happens.
While you hold it, your NFT collects its share of the coin's creator fees. Claim the HYPE whenever you like. Sell the NFT and the unclaimed fees go with it.
Burn the NFT and receive exactly its tokens, plus any fees it hasn't claimed yet, in one step. Swapping back is never paused.
Already hold the coin? Lock your own tokens into NFTs instead of buying.
// fee rewards
Up to 75% to holders
Elysium launch pays a coin's creator a fee on every trade. On elhashcash that creator fee is shared, and the creator decides how much goes to the NFT holders:
- The creator picks the holders' share at launch, anywhere up to 75%. Whatever they don't give to holders stays with them.
- Every collection shows its holders' share, so collectors can compare.
- Split equally per NFT; every NFT holds the same amount, so it's fair by design.
- Fees only count from the moment your NFT exists. Nobody can mint late and take earlier fees.
- Anyone can press “Collect fees” to move pending fees into the holders' pool.
- The launchpad's own protocol fee is separate and never shared.
The math
| Creator fees collected | 4.00 HYPE |
|---|---|
| Holders' share set by the creator | 50% |
| To NFT holders (50%) | 2.00 HYPE |
| To the creator (25%) | 1.00 HYPE |
| To elhashcash (25%) | 1.00 HYPE |
| NFTs in the collection | 4 |
| Each NFT earns | 0.50 HYPE |
// for creators
Launch a coin with its NFTs
A short wizard launches your Elysium launch coin and its NFT collection together. Choose how much of the coin's creator fees your holders get (up to 75%; you keep the rest of it). Buy some of your own coin at launch, lock part of it into NFTs and keep the rest as tokens.
Already have a coin? Back it with a collection. If you're its creator, you can turn on fee sharing for your holders.
- Create the coin on Elysium launch, with an optional buy in the same transaction.
- Share creator fees: your chosen share to NFT holders, the rest of the 75% to you, 25% to elhashcash.
- Create the collection with a fixed number of tokens per NFT.
- Lock your first NFTs from your buy; keep the rest as tokens.
// trust, not promises
Check it yourself
- Tokens sit in a vault owned by the contract. The code has no admin withdraw: tokens leave only when an NFT is swapped back.
- The contract checks after every action that the vault holds at least what all NFTs are owed.
- Anyone can recount every NFT's claim and the rewards pool from the chain, straight from the app.
- The admin can only pause new NFTs. Swapping back can't be stopped.
- Not audited yet, and upgrades are possible until the contract is locked. Both are on the roadmap below.
Status today
- Vault and rewards logic built and stress-tested offline: hundreds of thousands of random actions, with every accounting rule checked after each one.
- App and launch flow working end to end in a simulated environment.
- Next: public testing on Elysium, then an external audit.

Questions
What is the official contract address?
The official address is shown at the top of this page once the token is live. There is no presale. Any other address, or anyone sending you a “new CA” in DMs, is not us.
What do I get when I swap an NFT back?
Exactly the number of tokens printed on the NFT, plus any fee rewards it hasn't claimed yet. What those tokens are worth in HYPE depends on the market at that moment, so the value is not guaranteed.
Why do NFTs earn fees?
Coins launched through elhashcash share their Elysium launch creator fees: the creator chooses how much goes to the collection's holders (up to 75%), keeps the rest of that 75%, and 25% goes to elhashcash. Coins that already existed can join if their creator turns it on.
Can the coin's creator rug the vault?
No. The creator has no access to the vault's tokens. They could change the fee split later unless it is locked, and the app shows on every collection whether it is. Locking the split at launch is part of the roadmap.
What does it cost to mint?
The token price, plus gas in HYPE. Collections may add a fixed mint fee, shown in the price.
Which wallets work?
Any EVM wallet on Elysium, such as MetaMask or Rabby. We will never ask for your seed phrase.
