CryptoWorld.tradeHow to connect a wallet with WalletConnect
WalletConnect lets a desktop browser request a session from a mobile or browser wallet. The wallet remains in control of the keys; CryptoWorld only receives the public account and signatures you approve.
Before connecting
- Install or update MetaMask, Coinbase Wallet, or another WalletConnect-compatible wallet.
- Unlock the wallet and make sure it is connected to the internet.
- Use the official site: https://cryptoworld.trade.
- Never enter a seed phrase into a website, chat, or support form.
Connection steps
- Open CryptoWorld.trade and click Connect wallet.
- Choose WalletConnect.
- Scan the QR code with the wallet's built-in scanner. Do not use a generic camera app if the wallet has a WalletConnect scanner.
- Review the requesting domain and account, then approve the session.
- Return to CryptoWorld. The connected address and selected EVM network appear in the wallet balance card.
If the QR code fails
- Close and reopen the WalletConnect modal so the pairing URI is refreshed.
- Use Copy Link, then paste it into the wallet's WalletConnect input.
- Use Search Wallet and choose the wallet directly.
- Update the wallet app. Older versions may not support WalletConnect v2.
- If the site is embedded in another app, open it in a normal browser tab.
Network selection
After connecting, use the network selector on the wallet balance card to switch between Ethereum, Base, Arbitrum, Polygon, and Optimism. Switching networks asks the wallet to change chains. If the wallet does not support the chain, add it in the wallet first.
Signature safety
Read every wallet prompt. A connection request should only request account addresses. A transaction request should show the network, recipient, amount, and fee. Reject unexpected approvals, unlimited token allowances, or requests for a seed phrase.
Troubleshooting
If the QR screen is blocked by a browser policy, refresh the page and try again. If the wallet shows an unsupported-application warning, update the wallet or use the Coinbase Wallet SDK option in the connection modal. If a session is stale, disconnect it in the wallet and create a new one.
Frequently asked questions
Does WalletConnect give CryptoWorld my private key?
No. The wallet keeps the key and only shares the public address and approved signatures.
Why does the site not see my balance?
Check that the wallet is on the same network selected in CryptoWorld and that the account has a funded balance on that chain.
Can I use TRC20 with WalletConnect?
TRON is a separate non-EVM network. Use TronLink for TRX and TRC20 balances; WalletConnect handles EVM chains.
