Want to connect Cronos to MetaMask? This guide walks through adding the Cronos network to your MetaMask software wallet (both the browser extension and the mobile app), shows what to check after you switch networks, and highlights common security pitfalls.
I use multiple EVM-compatible chains every week, and adding an extra network is a routine step before interacting with Cronos-native DeFi or bridging assets. What I've found: the process is quick, but the usual smart-contract and approval risks still apply. And yes, verify any network details before pasting them.
Why the checks? Because adding a custom network means MetaMask will start signing transactions on that chain using your private keys. Keep them offline and secure.
Common Cronos mainnet settings (example — verify from Cronos official docs before adding):
| Field | Example value |
|---|---|
| Network Name | Cronos Mainnet |
| New RPC URL | https://evm-cronos.crypto.org |
| Chain ID | 25 |
| Currency Symbol | CRO |
| Block Explorer URL | https://cronoscan.com |
If the form looks different, try Settings → Networks → Add Network (some versions of MetaMask move the controls around). If you prefer, use the generic add custom network flow described in our general guide.
Alternatively, when you open a Cronos dApp in the MetaMask in-app browser or connect via WalletConnect, the app may prompt you to add or switch to Cronos automatically. Always check the RPC and explorer link in that prompt before accepting. But if you want manual control, use the menu path above.
If you need help linking mobile dApps via WalletConnect, see WalletConnect mobile linking.
Small tip: If a token doesn't show up after switching networks, confirm that the token exists on Cronos and that you imported the right contract address (common mistake).
| Feature | Browser extension (desktop) | Mobile app |
|---|---|---|
| Best for multi-tab dApp workflows | Good | Fair |
| Easier WalletConnect pairing | Limited | Native (in-app browser) |
| Fast network switching | Quick (top dropdown) | Quick (menu) |
| Touch/biometric protection | Depends on OS | Often available (biometrics) |
If you swap tokens frequently across many dApps, the desktop extension is convenient. If you live on your phone, the mobile app’s in-app browser and WalletConnect flow save time. In my experience, I use both: desktop for longer sessions, mobile for quick swaps and on-the-go checks.
But don’t assume convenience equals safety. A hot wallet is a software wallet designed for daily activity — that convenience comes with more exposure than a hardware wallet.

Q: Is it safe to keep crypto in a hot wallet?
A: Hot wallets are practical for daily DeFi and quick swaps, but they are more exposed than hardware wallets. I keep small balances for trading in a hot wallet and larger holdings in cold storage. (Balance convenience with security.)
Q: How do I revoke token approvals for Cronos tokens?
A: With MetaMask on the Cronos network you can review recent transactions and allowances, and revoke them using the in-wallet tools or trusted on-chain approval revokers. See token approvals & revoke for step-by-step guidance.
Q: What happens if I lose my phone?
A: If you backed up your seed phrase, restore it on a new device using the same wallet software and your seed phrase. If you didn’t, funds in that wallet are likely unrecoverable. See backup & recovery and backup cloud vs paper.
Adding Cronos to MetaMask is a straightforward way to access Cronos-based DeFi, NFTs, and other dApps from your software wallet. Follow the steps above, double-check RPC and explorer links, and treat approvals and seed phrase backups with care. If you want step-by-step setup for your device, check the browser extension install or mobile install guide next. Ready to add Cronos and start interacting with Cronos dApps safely?
If so, try the steps above and keep backups secure. For more on gas controls and fee management across EVM chains, see gas fees & EIP-1559.
