Every trade drips into the trap. The trap saves for a grail.

Grailtrap launches ordinary pump.fun coins with one change: the coin's on-chain creator is a fresh wallet made for that coin, the trap. Its creator fees collect there until they cover a real graded trading card, which is bought and sent to one holder, picked by a draw anyone can replay.

One sweep, top to bottom

About every ten minutes a job runs once for each coin. It goes down the same seven steps every time, and every step that moves money writes a ledger row with its transaction signature. Scroll down the shaft to follow one run.

Deliver

Unfinished business first. A card that was bought on an earlier sweep but never reached a winner gets another delivery before anything new happens. If its new owner already holds it, the row is just marked sent.

Refresh

Read the coin's price and market cap from its bonding curve, or from its PumpSwap pool once the curve is complete. The first time a coin graduates, that gets a ledger row of its own.

Claim

pump.fun pays the coin's creator a fee on every trade: 0.30% of volume on the bonding curve, 0.05% on PumpSwap after graduation. Here the creator is the trap. Once its creator vault holds at least 0.005 SOL, the sweep claims it, then pays the launcher's cut (0 to 15%, fixed at launch) and the platform's 10%. The rest stays in the trap.

Value

Count what the trap can actually spend: its SOL above a 0.01 SOL reserve kept back for fees and rent, plus any USDC left over from an earlier catch, priced in USD at Jupiter's SOL price. This step moves nothing, so it writes no ledger row. It updates the coin's trap meter.

Coin recordupdated, no ledger row

ball_lamports: SOL balance
ball_usdc: leftover USDC
ball_unclaimed: still in the creator vault
ball_usd: (SOL − 0.01) × price + USDC

From the example claim, 0.2975 SOL lands in the trap. At $83.24 per SOL that adds $24.76 to the trap meter, assuming the 0.01 SOL reserve is already covered.

Depth 05 / 07

Catch

The trap catches once it holds the tier floor plus $2.50 for slippage and fees. The sweep asks Collector Crypt's marketplace for the priciest listing it can afford inside the band (matching the launcher's name target, if one was set), swaps only the USDC shortfall through Jupiter with an exact-out quote, buys, then confirms on chain that the trap owns the card.

Tier for the example above

CommonRareHoloLegendary

$17.74 more until the next Rare catch (target $42.50). From an empty trap that is about 0.601 SOL of claimed fees, or roughly 200 SOL of bonding-curve trading at the 0.30% creator fee.

Draw

Right after the buy confirms, the sweep snapshots the coin's holders from the chain. The bonding curve, the pool and the trap itself are left out, and so is any wallet under 100,000 tokens (0.01% of supply). Odds follow tokens held.

The seed is sha256(buySig:mint). Its first 13 hex characters (52 bits) become a number between 0 and 1, walked across the holders sorted by wallet. The seed and the holder count are stored with the catch, so anyone can run it again and land on the same wallet.

The vault floor

A launcher picks one door when the coin is made, and it stays that door for the coin's whole life. The trap opens it when it holds the floor plus $2.50, and it buys the priciest card it can afford inside the band, so a trap that has been filling for a while catches a better card.

Common

$12 – $40

First catch at $14.50

Graded cards from $12. The trap fills fast and catches often.

Rare

$40 – $150

First catch at $42.50

Mid-tier slabs. A steady coin catches now and then.

Holo

$150 – $600

First catch at $152.50

Serious cards. Fewer catches, bigger reveals.

Legendary

$600 – $5,000

First catch at $602.50

The trap saves for one grail.

An optional name target narrows the hunt, for example Charizard or Base Set. If nothing with that name is listed in the band, the trap keeps filling and looks again next sweep.

What can go wrong

Nothing is promised. Creator fees are about 0.3% of curve volume and 0.05% after graduation. A trap fills only as fast as people trade.
The trap's key is custodial. It is encrypted with a master key and decrypted only inside the sweep, which is the only thing that can spend from it.
Only some listings qualify. The sweep buys Core-standard, Collector Crypt native listings priced in USDC. Other marketplaces and older token standards are skipped.
A card can wait. If no wallet holds 100,000 tokens at the snapshot, the card stays in the trap until one does.
Prices move. The trap is valued in USD at each sweep, so a falling SOL price pushes the next catch further away.
No affiliation. Grailtrap is not affiliated with pump.fun, Collector Crypt, Jupiter or any card publisher. It uses their public programs and APIs.

Set a trap for your coin

One wallet-signed transaction creates the coin with its trap as creator. You pay only the mint rent, plus a dev buy if you add one. Trading on Grailtrap adds no fee of its own; trades pay pump.fun's normal fees.
