What Wallet Integration Actually Reveals About an Ethereum Casino

Connecting a wallet directly to a platform has become the default way for crypto users to interact with DeFi protocols, NFT marketplaces and online casinos. In order to play at Ethereum casinos players can now deposit and withdraw funds directly from their wallets, instead of first transferring funds to a custodial account and then from there placing bets.

This piece explores what adding support for wallets to interact with online casinos actually means for players. Why this feature is more important for support on the Ethereum platform than on other smart contract platforms, and most importantly how to check if support for wallets has actually been implemented by a casino platform.

What Changes When a Casino Supports Direct Wallet Connections

Custodial deposits versus wallet-based play - traditional online casinos hold player funds in an internal account balance, while wallet-integrated platforms let a player retain custody until the moment a bet is actually placed.

1. MetaMask Support: Many Ethereum Casino platforms using wallet integration support 

2. MetaMask Wallet as well as other wallets. This ensures that players can play in the casino using their existing Ethereum wallet without having to download or sign up to another service. 

3. Likewise WalletConnect support allows for the greatest flexibility in terms of the Ethereum wallets that players can use to connect to a casino.

4. Visible gas fees - in contrast to custodial gambling sites, where hidden fees are either charged on top of the advertised rate or are simply absorbed into the exchange rate, all wallet-based transactions now clearly display the network fees upfront.

5. Interacting with Smart Contracts – This feature enables players to directly interact with the smart contract of a casino, in turn enabling on-chain fairness verification.

6. Transfer speeds – Money is transferred instantly and directly to your connected wallet(s) and thus does not get held up in a platform’s internal transfer ledger(s) even for withdrawals.

7. Notice the risk of change of custody of funds – In comparison with a traditional account, a deposit by means of a wallet is a fundamentally different thing. For a period of time funds are held by a different entity (the platform) and, at the time of withdrawal, are released back to the wallet. How do you like to sleep at night?

Why This Matters More on Ethereum Specifically

Wallets for gambling, particularly on Ethereum, have the most mature implementations of any smart contract platform. This is why a variety of implementations of wallet integrated gambling for deposits became possible first on Ethereum. For example, WalletConnect is a widely used open source project for connecting between wallets and websites. A casino can easily implement deposit by Ethereum using WalletConnect.

That familiarity cuts both ways.

The connection for wallet-integrated play at online Ethereum casinos is typically built on the same standards as used by DeFi protocols. But whereas for DeFi protocols such as a lending protocol players check the due diligence for connection of their wallet in order to lend, for online gaming sites such as Ethereum casinos, in most cases, no due diligence is performed by the player for connecting their wallet.

This due diligence would amongst others consist of checking of the permissions requested by the casino for connection of the wallet, for checking of the gas cost estimates for transactions, for checking of whether the casino uses a smart contract on the blockchain for processing of transactions for the games offered by the online gaming site, and for checking of the speed of withdrawal of funds from the online gaming site. 

In most cases, no such checks are performed and players simply click on the pop-up for connection of the wallet without reading the permissions requested and without understanding what the connection of the wallet actually authorizes.

Some of the above platforms are cataloged at crypto casinos with ETH wallet support and described in more detail as to whether they are running their games on top of smart contracts which have been thoroughly audited or if they are using the wallet only for depositing and withdrawing funds.

How to Evaluate a Platform's Wallet Integration

1. Does the wallet integration only cover deposits and withdrawals or does it also include the actual game logic (i.e. does it run on a smart contract?).

2. Check whether the platform supports widely used standards for wallet connections (e.g. WalletConnect) or a proprietary connection to the casino.

3. Get the current gas cost for your transaction to see how much it will actually cost you before you confirm the transaction.

4. Permission verification for wallet connection.

5. Test a small transaction first to confirm withdrawal speed before committing larger amounts.

Checking for wallet integration and evaluating how a casino uses smart contracts to facilitate gambling can take less than five minutes to complete. In most cases, players are presented with a set of permissions when connecting a wallet to a casino’s website or app. Most players read through the list of permissions and click to connect without giving it a second thought.

What This Signals About Broader Ethereum Adoption

Consumer applications are adopting the same tooling that already exists in DeFi for their wallet-integrated gambling. The same due diligence habits that you would use when connecting your wallet to a lending protocol (e.g. checking the permissions that are requested, understanding what a transaction actually authorizes), are just as relevant when connecting your wallet to a casino.

It is going to become increasingly obvious as more platforms adopt wallet-based transactions for real money online gaming whether or not they have implemented a real on-chain solution for a casino or simply use wallet support for deposit/withdrawals. It will be similar to how we currently can look at a DeFi protocol’s audit to see if they have been built with the proper rigor or not. A simple connect button to a wallet does not automatically mean that the online gaming platform has been built with the proper rigors of a real on-chain casino for true on-chain fairness verification.

Responsible Gambling

While many of the casinos listed will allow you to gamble with money from your wallet, remember that adding a deposit layer between your wallet and online casino will do nothing to reduce the risk of losing large amounts of money playing for real money online at any gambling website. That said, online casino wallet gambling really is no different from playing at offline land based casino’s, it’s just that for online versions players must enter their financial information to an online casino first. So, as with other forms of recreation, don’t bet with money that could be better used elsewhere, i.e. be responsible!
