How it works

Pick any coin

Any SPL or Token-2022 memecoin in your wallet, like 1,000 ANSEM. Choose exactly how much goes in.

Graded

Graded coins carry a 1 to 10 grade from public Jupiter data: age, holders, liquidity and organic volume. A coin not graded yet seals RAW.

Sealed in a slab

One slab, one token on Solana, with its own cert number. List it, box it or hold it.

The slab gets a coin

Each slab launches its own pump.fun coin. Its creator fees buy more of the memecoin inside, every 5 minutes.

Crack it anytime

Burn the slab and the coins inside go straight back to your wallet.

The slab program

seal(amount)

Locks an exact amount of any coin in a vault owned by the slab (coins with a freeze authority, permanent delegate or transfer hook are refused, because they could move tokens out), and mints the slab token: supply 1, mint authority removed in the same transaction, so no second copy can ever exist.

feed(amount)

Adds more of the slab's coin to its vault. The keeper calls it with the coin it bought from the slab coin's fees. Anyone can top up a slab, nobody can take from one.

load_slab · pull_slab

Loaders put slabs into a machine. A pull pays the machine price in SOL into a pull account, and from that moment nothing can be loaded or taken out.

settle_pull

The pick is the hash of the first Solana slot after the pull, mixed with the pull's address: fixed after you pay, chosen by nobody. The slab goes to the buyer, the loader gets the price minus 5%. If nobody settles within 400 slots, the buyer gets the SOL back.

list · buy · delist

A listed slab sits in an escrow owned by its listing. The buyer pays in SOL and gets the slab in the same transaction; the seller gets the price minus 5%. The buyer sets a price limit, so a seller cannot raise the price in front of a sale.

grade_lock()

Reads a Streamflow token lock in the same transaction that created it and issues a BAGEM cert only if it is a true lock: you are its sender, it holds this coin, nobody can cancel it, it cannot be moved, topped up or auto-withdrawn, at least 99% unlocks at one date, nothing has been withdrawn and that date is at least a day away. One cert per lock.

crack()

Burns the slab token and sends everything in the vault to whoever holds it. Only the holder can crack, and the vault closes for good.

Tested. 61 of 61 tests pass on a local Solana validator: sealing any coin (and refusing coins that could drain a vault), feeding, cracking, mystery box pulls with refund, market listings, price changes and sales, and grade locks against the real Streamflow lock program. The source code and the mainnet program address are published at launch.

Questions

What is inside a slab?

An exact amount of a real Solana memecoin. The label shows the coin, the amount and the grade, and every coin mint links to Solscan. The value moves with the coin's live Jupiter price.

How are machine odds set?

Every slab in a machine has the same odds. The pick is the hash of the first Solana slot after your pull, mixed with your pull's address, so it is fixed the moment you pay and nobody chooses it. While a pull waits, no slab can be loaded or taken out.

Why does my slab grow?

Every slab trades as its own coin on pump.fun, paired with SOL, and its creator is the slab vault. pump.fun pays the creator fee in SOL on every trade. Every 5 minutes a keeper claims it, buys the slab's memecoin through Jupiter and deposits it into the slab. Each claim and buy is a public transaction. Whoever holds the slab owns everything inside it, including what the fees added.

Which coins get a grade?

Established Solana memecoins that people still trade. A coin is graded when Jupiter shows a market cap of $1M or more, $75K+ liquidity, real trading in the last 24 hours ($5K+ volume, 50+ traders), 10,000+ holders, a first pool at least 45 days old and an organic score of 45 or more. Any other coin can still be sealed, as RAW.

How is a coin graded?

Ten points from public Jupiter data. Age since first pool: 3 for two years, 2 for one year, 1 otherwise. Holders: 3 for 500K, 2 for 100K, 1 for 50K. Liquidity: 2 for $5M, 1 for $1M. Jupiter organic score: 2 for 80, 1 for 60. A 10 is a GEM MT bag.

What is a grade lock?

A dev lock with a grade on it. Your tokens go into a standard Streamflow token lock that nobody can cancel, so they count as locked supply anywhere Streamflow locks are read. BAGEM checks the lock on-chain and gives it a cert, a share page and a card. On the unlock date the tokens go back to your wallet.

Can I get my coins back?

Anytime. Crack the slab by burning its token and the coins inside go back to your wallet.

What do I need to start?

A Solana wallet like Phantom. Connect it, pick a slab and roll. No sign-up, no email.
