Trench Grading Company odds

Odds & fairness

Every slab is graded independently. Its grade decides its rarity and its share of the daily $RIPPED payout. Any of the 101 Series 1 coins can land at any grade.

Holder Luck Boost

Hold $RIPPED and every pack you rip rolls with better odds for Epic, Legendary and Mythic slabs. The extra comes out of TGC 6. Holders are snapshotted every hour: your boost is your tier at the last snapshot, as long as you still hold that much when you rip. Anything you buy counts from the next snapshot.

How a pack is graded

I. Your pack's transaction lands on Solana. Its signature is fixed when you sign; the hash of the block that includes it is not known until the network produces that block.

II. Seed = sha256("signature:blockhash"). Nobody, including us, can know it before your transaction lands.

III. For slab i, HMAC-SHA256(seed, "slab:i") gives two 48-bit numbers: the first mod 10,000 picks the grade from the table above (or the Holder Luck Boost table the pack was quoted with, shown in its roll proof), the second picks the coin.

IV. Paste any pack into the verifier and you get the same five grades TGC gave.
