Teexas Hold'em
Nobody sees your cards.
Not even the house.
No-Limit Hold'em dealt inside a MagicBlock Private Ephemeral Rollup on Solana.
The dealer is a server. The server sees every card.
An Absolute Poker insider used a “superuser” account to watch every player’s hole cards.
The same scheme surfaced at UltimateBet.
Players still trust a database they can’t read, a shuffle they can’t audit, and a withdrawal desk.
Two bad options
Every account is readable by anyone. Your cards are public.
Private, but seconds and many round-trips per action. Nobody plays it.
The dealer is a hardware-sealed vault on Solana
Table, deck and hands are delegated to a MagicBlock Private Ephemeral Rollup on Intel TDX.
MagicBlock VRF mixed with an entropy pool every player stirs. Nobody can predict a deal.
Buy-ins sit in a Solana vault. The winner is paid automatically when the table returns.
Privacy enforced by the enclave
| Table, bets, board, pot | Everyone, including spectators | Public account |
| Your two hole cards | Your wallet + your session key | Permission with 2 members |
| The deck | Nobody — only the program inside the TEE | Permission with 0 members |
| Hands at showdown | Everyone | Flipped public by the program |
| A hand you choose to show | Everyone, after the hand | Only your key can flip it public |
| Folded hands | Only their owner | Stay private, wiped at the end |

Every action adds 32 random bytes from the player's browser to a pool that lives in the member-less deck account. The oracle never learns the pool; players never learn the VRF output.
Fast, free, popup-free
A table-scoped session key plays for you: no popups mid-hand, and it can never move your funds. Every step that advances a game is permissionless, so players, spectators, or a public keeper bot can drive any table to the end.
Privacy you control, play that's social
After a hand, flip your own hand public, say to show a bluff. It is a permission update only your key can make; the next deal seals it again.
Eight emotes, each a rollup transaction: free, about 50 ms, seen by the whole table.
A maniac who shows his bluffs, a rock, a calling station, a gambler and a machine, all under the same TEE rules.
Settlement writes every human's result into a per-wallet account. Nobody submits a score; nobody can edit one.
One tap posts a generated result card to X: “I won. Nobody saw my cards.”
Same settings, same robots, a fresh table and a new invite link.
