Covenant-controlled
Stakes move only through the game states, timeout branches and payouts admitted by the on-chain program.
Blackjack without a casino balance
Your money follows code, not a promise
You do not deposit KAS into a KaspaForge account. A room and a game are covenant-controlled UTXOs on Kaspa L1. The browser checks the room terms, builds the exact transaction and signs each move locally. KaspaForge coordinates the game, but it cannot extract your key or rewrite a valid payout.

Browser-local
Your encrypted Desk profile holds the signing keys. Private keys are never sent to the game server.

Proof-backed
Commitments fix the randomness, a ZK proof certifies the hidden shuffle, and Merkle paths authenticate revealed cards.

FAQ
Before you sit at a table
Is Kaspa Blackjack live?
Yes. KaspaForge Arena Blackjack is a public mainnet beta with open S17 tables at six stake tiers from 5 to 100 KAS.
What makes it provably fair?
Both sides commit to randomness before the deck is known. A zero-knowledge proof certifies the shuffle, Merkle paths authenticate revealed cards, and the Kaspa covenant enforces legal game states and payouts.
Does KaspaForge hold my KAS or keys?
No. Keys remain in the encrypted Desk profile in your browser, moves are signed locally, and stakes sit in covenant UTXOs rather than a custodial casino balance.
Do I need an account or a token?
No platform account, bridge or token is required. You use a local Desk profile and plain KAS.
Can I verify a completed hand?
Yes. The public verifier checks post-settlement evidence. Its SCOPE document states exactly which claims it verifies and which chain-level checks remain outside the package.
