This guide shows how to connect Fantom to MetaMask by adding the network manually (RPC URL, Chain ID, currency symbol and block explorer). If you prefer, there are also automated ways to add networks in some wallets, but here I walk through the manual, explicit method so you can verify each value before you save it. Short and practical. I've added Fantom to MetaMask many times while testing DeFi flows; I’ll share what to watch for.
Fantom is an EVM-compatible chain used by a number of DeFi protocols and dApps. Adding Fantom to a software wallet like MetaMask lets you:
Why not just use a bridge UI in a browser? Because switching networks in MetaMask is faster for daily swaps and for approving contracts (one fewer step). And yes — there are trade-offs: a hot wallet is convenient but has different security trade-offs compared with a hardware wallet.
Below are the core fields MetaMask asks for when you add Fantom. Copy them exactly into the Add Network form in MetaMask.
| Field | Typical value |
|---|---|
| Network Name | Fantom Opera |
| New RPC URL | https://rpcapi.fantom.network (public RPC) |
| Chain ID | 250 |
| Currency Symbol | FTM |
| Block Explorer URL | https://ftmscan.com |

A few notes: Chain ID is how wallets and dApps identify the blockchain (250 identifies Fantom mainnet). The RPC URL points your MetaMask to an RPC node that serves chain data. If a public RPC is slow, try an alternative public endpoint or a paid provider — or run your own node if you need maximum privacy and reliability.
If you need a refresher on installing the extension first, see the install guide: Install MetaMask extension.
To connect Fantom from mobile dApps, the in-app browser will use the active network. If you prefer a direct install, read the mobile installation steps here: Install MetaMask mobile app.
But if a dApp offers an automatic "Add network" button, double-check the values before accepting.
MetaMask won’t automatically show every token on Fantom. To add a token:
For NFTs, the wallet will show ERC-721 and ERC-1155 assets if the dApp metadata is available. Spam NFTs can clutter your list — hide them or use specialized NFT managers. For token management workflows and approval cleanup, see token-approvals-revoke.
Most Fantom dApps expect an injected provider (MetaMask) or WalletConnect. After switching MetaMask to Fantom Opera (Chain ID 250), the dApp should detect the network. If it asks to switch, confirm in MetaMask.
Built-in swap features in wallets vary. If you plan to swap often on Fantom, check the wallet’s aggregator routing and slippage controls before hitting Confirm. For staking, some apps let you stake native FTM directly or use liquid staking; always confirm validator reputations and smart contract audits (link to a staking guide: staking-via-metamask).
And always double-check contract addresses and UX prompts. Phishing dApps and fake RPC endpoints are real risks.

Who should look elsewhere:
Q: Is it safe to keep crypto in a hot wallet?
A: Hot wallets balance convenience and security. For day-to-day DeFi interactions they’re practical, but for larger sums consider using a hardware wallet or multisig. See security-best-practices.
Q: How do I revoke token approvals on Fantom?
A: Use a reputable approval-revoke tool or a wallet feature that lists allowances. Revoke unlimited allowances and re-approve with a limited amount when needed. See token-approvals-revoke.
Q: What happens if I lose my phone?
A: If you have your seed phrase backed up, you can restore the wallet on another device. Without the seed phrase, recovery is unlikely. Read backup-recovery-seed and lost-phone-recovery.
Connecting Fantom to MetaMask is a small setup step that opens access to Fantom-based DeFi and dApps. Add the network by entering the RPC URL and Chain ID (250), then import any tokens you use. I recommend testing with a small transfer first to confirm everything works as expected. In my experience, that extra test transfer saves headaches.
