How Rollhouse Works – Base Wallet Sign-In and Demo Casino Games

What is Base?

Base is an Ethereum layer 2 network incubated by Coinbase. It settles to Ethereum, uses ETH for gas and works with the same wallets and addresses as Ethereum mainnet, so the wallet you already use for Base apps works on Rollhouse without any setup.

Supported networks: Base, BSC and what is next

Rollhouse signs you in with your EVM address, so one wallet works across every chain we support. Base and BNB Smart Chain (BSC) are live now; Ethereum mainnet and Robinhood Chain are coming soon and will be switched on here when they are ready.

Signing in with your wallet

Press Sign in with wallet. Rollhouse uses the wallet built into your browser, such as MetaMask, Coinbase Wallet or Rabby. On a phone, open rollhouse.xyz in your wallet app's built-in browser.
Make sure your wallet is on Base (chain ID 8453) or BNB Smart Chain (chain ID 56). Other networks are refused.
Your wallet shows a short Sign-In with Ethereum (EIP-4361) message for rollhouse.xyz with a one-time code. Signing it proves you control the address.
The server checks the signature and starts an 8-hour session in a secure, HTTP-only cookie. Signing out ends it immediately.

Signing in never asks for a transaction or a token approval, costs no gas and cannot move funds. You do not need to sign in to play: guests get the full demo. Signing in adds a profile, ROLL points, the leaderboard, referrals and PvP coin flip rooms.

How rounds are resolved today

When you play, your browser sends the wager and your choices to the Rollhouse server. The server validates them, draws the outcome with Node.js's cryptographic random number generator (crypto.randomInt), works out the payout from the published paytable and sends back the result with a round ID. Your browser then updates the demo balance.

Rounds are not recorded on Base or any other blockchain, and Rollhouse is not provably fair yet: there is no server-seed and client-seed commitment you can verify after the fact, so you are trusting the server's random draw. Each game page lists its exact payouts and house edge, which run from 1% (Dice, Limbo) to about 4.4% (Plinko).

Demo limits

Every browser starts with 1,000 demo credits, with a reset when you run out. A single wager can be 0.01 to 1,000 credits.
The demo balance is stored only in your browser. Clearing site data or switching device starts it over.
Demo credits and ROLL points have no cash value. They cannot be bought, deposited, withdrawn, transferred or exchanged for anything.
There are no deposits, withdrawals or real-money wagers on Rollhouse.
