Using Web3 wallets to play anonymously

Introduction

Web3 wallets have become a key tool for anonymous access to poker casinos without e-mail and passwords. Instead of accounts, you use your crypto address and sign a short message - and get instant access to rates. Below is a clear algorithm for which wallets are suitable, how to connect, what risks to take into account and how to minimize them.

1. Choosing a Web3 Wallet

1. MetaMask (browser and mobile app)

Support for EVM networks (Ethereum, BSC, Polygon).
Extensions for Chrome/Firefox and mobile client.
2. WalletConnect (universal bridge)

Connect via QR code to any supporting DApp wallet (Trust Wallet, Rainbow).
3. Trust Wallet (mobile)

Built-in DApp browser, convenient for PWA versions of casinos.
4. Hardware wallets with Web3 integration

Ledger, Trezor via MetaMask or other bridges.
Maximum protection when signing.

2. Authorization process

1. Connecting your wallet

On the casino site, click "Connect Wallet" and select MetaMask or WalletConnect.
2. Nonce Message Signature

The wallet will request a random text signature (no commission).
After signing on the client, you receive a JWT token or session identifier.
3. Set session cookies or LocalStorage

The game session is tied to a wallet, without an e-mail and password.

3. Bets and transactions

1. Bid via sendTransaction

DApp forms a transaction to the address of the slot smart contract, indicating the amount in ETN/tokens.
Confirmation in the wallet: check the recipient's address, amount and gas price.
2. Gas and optimization

Use low gas networks (BSC, Polygon) for cheap and fast bets.
In MetaMask, enable the "Advanced gas controls" option for manual configuration.
3. Automatic payouts

After calculating the result, the smart contract will send the winnings to your address without additional confirmation.

4. Ensuring privacy

1. Separate wallets

Gaming wallet: a small balance for bets.
Cold wallet: storing large funds outside the browser.
2. Using mixers and ZK protocols

Tornado Cash, Railgun для Ethereum; Railgun for BSC.
zkSync wallets with private transfers.
3. VPN and metadata protection

Connect via a trusted VPN with a no-logs policy.
Enable DNS over HTTPS/TLS and disable WebRTC in the browser.

5. Security at signing

1. Hardware confirmations

Sign bets and transactions on Ledger/Trezor to ensure the transaction is not superseded.
2. Thorough data verification

Always check the address of the smart contract and the value of the bet according to the official sources of the casino.
3. Restriction of access rights

For tokens, use minimum approve amounts, not infinite allowance.
Regularly revoke unnecessary permissions through tools like Etherscan Token Approvals.

6. Test transactions and limits

1. Mini deposit for verification

Send 0.01 ETH or equivalent in a token, measure the turn-on time and gas commission.
2. Verification of output

Request the output of the same 0.01 ETH and check that the payment is received automatically.
3. Setting limits

MetaMask: Settings → Advanced → Max fee limit for each network.

7. Practical advice

Use the latest versions of wallets and browsers - new releases close vulnerabilities.
Connect only to official DApp sites - copies and phishing interfaces are often disguised as the original.
Store the seed phrase offline and never enter it in the browser.
Monitor whitelist certificates through HSTS lists and certificate pinning.

Conclusion

Web3 wallets give direct, anonymous and secure access to pokie casinos without traditional logins and passwords. Choosing the right wallet, verifying connectivity, protecting privacy and test transactions are key steps for a secure and confidential game.
