Hey there! If you're new to crypto and just getting started with wallets, terms like "multi-chain" and "switching networks" can feel overwhelming. Phantom Wallet started as the go-to wallet for Solana, but it's now a full-fledged multi-chain wallet that supports Ethereum, Base, Sui, and more.
As of 2026, Phantom has over 15 million active users and lets you manage assets, swap tokens, connect to dApps, and handle NFTs across multiple blockchains—all without needing separate wallets like MetaMask or Sui Wallet.
1. What Is Phantom Wallet? Why Does It Support Multiple Chains?
Phantom is a non-custodial wallet (meaning you control your private keys), originally built for Solana with a clean, user-friendly interface that's as easy as a mobile banking app. Starting in 2023–2024, Phantom expanded to become a true multi-chain wallet, adding support for Ethereum, Polygon, Bitcoin, Base, Sui, Monad, HyperEVM, and more.
Key advantages of multi-chain support:
One seed phrase manages assets across all supported chains
Built-in cross-chain swapper (no need for external bridges in most cases)
View NFTs, stake tokens, and connect to dApps on different networks
Built-in security scans for suspicious transactions
In 2026, the officially supported chains include: Solana (always on), Ethereum, Base, Polygon, Sui, Bitcoin, Monad, and HyperEVM. Ethereum, Base, and Sui are all natively supported—no manual RPC setup required!
2. How to Install and Set Up Phantom (Beginner Steps)
Browser Extension (Recommended for Desktop):
Go to the official site: phantom.app (double-check the URL to avoid fakes!)
Download the extension for Chrome, Edge, or Firefox
Create a new wallet → Set a strong password → Back up your 12-word seed phrase (write it down offline—never screenshot or share it!)
Done! Solana is enabled by default.
Mobile App (iOS/Android):
Search for “Phantom” in the App Store or Google Play (only the official one!)
Import an existing wallet or create a new one, and back up your seed phrase
Pro tip: Start with tiny test amounts (like $1–5 worth of tokens) to get comfortable before moving larger sums.
3. How to Enable Ethereum, Base, and Sui? (The Key Switching Steps)
Unlike MetaMask, where you manually add and switch networks, Phantom uses an Active Networks system. You enable chains once, and then switch between them easily in the interface.
Step-by-step to enable chains (same on browser and mobile):
Click your profile/avatar (top-left or bottom-right settings icon)
Go to Settings → Active Networks
Toggle on the chains you want:
Ethereum → Enables Ethereum Mainnet
Base → Enables Coinbase's Layer 2 network
Sui → Enables the Sui blockchain
Save changes. Your wallet home screen will now show addresses and balances for each enabled chain.
Important notes:
Ethereum, Base, and Polygon are EVM-compatible → They share the same address (starts with 0x…). Just select the correct network when sending.
Sui uses a separate address format (starts with sui…). It has its own view.
Solana is always active and can’t be turned off.
Once enabled, switch views by clicking the chain icon or dropdown at the top of the wallet → Select “Ethereum,” “Base,” or “Sui” to see that chain’s balance, transaction history, and NFTs.
4. Ethereum, Base, and Sui: Hands-On Guide
Ethereum (Mainnet):
Address: 0x… (same as Base)
Receive: Click “Receive” → Select Ethereum → Copy address
Send: Choose token → Send → Paste recipient address → Enter amount (watch gas fees!)
Best for: Major DeFi (Uniswap), blue-chip NFTs
Base (Coinbase Layer 2):
Address: Identical to Ethereum (0x…)
Once enabled, your ETH appears under Base (but Base ETH is different from Ethereum Mainnet ETH)
Advantages: Super-low gas fees (usually under $0.10), fast transactions
Use the same send/receive steps—just select “Base” network
Sui:
Address: Unique sui… format
Enable it → SUI tokens appear automatically
Receive/send: Select Sui network (SUI pays for gas)
Built-in swaps support Sui ecosystem tokens (Cetus, Suilend, etc.)
5. How to Move Funds Between Chains? (Using the Built-in Swapper)
The easiest way to “switch” assets isn’t manual bridging—it’s Phantom’s Cross-chain Swapper:
Go to the home screen and click “Swap”
In “You Pay,” select your source token and network (e.g., USDC on Ethereum)
In “You Receive,” pick your target token and network (e.g., USDC on Base or Sui)
Enter amount → Review quote (includes gas + bridge fees) → Confirm
Wait a few seconds to minutes—done!
It supports seamless swaps between Ethereum 
Base Sui Solana and more, routing through the best DEX paths automatically. Great for beginners—test with small amounts first.
Data Comparison Table
Here’s a 2026 comparison of Ethereum, Base, and Sui in Phantom (based on official docs and real-time chain data—always check current values):
| Feature | Ethereum (Mainnet) | Base (Coinbase L2) | Sui |
|---|---|---|---|
| Gas Token | ETH | ETH (on L2) | SUI |
| Average Gas Fee | $1–$10 (higher during peaks) | $0.01–$0.10 | <$0.01 |
| TPS (Transactions per Second) | ~15 | Hundreds to thousands | 10,000+ (parallel execution) |
| Address Format | 0x… (shared with Base) | 0x… (shared with Ethereum) | sui… (separate) |
| How to Switch in Phantom | Active Networks + chain selector | Active Networks + chain selector | Active Networks + chain selector |
| Main Strengths | Most mature ecosystem, full DeFi/NFTs | Ultra-low fees + speed, Coinbase integration | High performance, Move language, gaming/DeFi growth |
| Phantom Features | Swaps, dApp connections, NFTs | Cross-chain swaps, low-fee ETH | Swaps (Cetus-powered), staking |
| Beginner Friendliness | Medium (higher fees) | Very high | Very high (cheap & fast) |
Quick takeaway: Base and Sui crush Ethereum on cost and speed—perfect for everyday use—while Ethereum wins for deep DeFi liquidity. Phantom makes all three work together smoothly.
Q&A
Q1: Does Phantom really support multiple chains in 2026? Which ones?
A: Yes! Official support includes Solana, Ethereum, Base, Polygon, Sui, Bitcoin, Monad, HyperEVM. Ethereum, Base, and Sui are fully native.
Q2: How do I switch between Ethereum, Base, and Sui in Phantom?
A: Enable them in Settings → Active Networks, then use the chain selector (top dropdown) to view and operate on each one.
Q3: Do Ethereum and Base share the same address? Will I lose funds if I send to the wrong network?
A: Yes, same 0x… address—but networks are different! Always double-check the selected network before sending, or funds could get stuck (recoverable but annoying).
Q4: Sui has a different address—how do I find it?
A: Enable Sui → Click “Receive” → Select Sui network to show your sui… address. Use SUI for gas.
Q5: Are cross-chain swaps in Phantom safe? Any fees?
A: Very safe—Phantom scans transactions and routes through trusted DEXs. Fees include ~0.85% Phantom fee + gas + small bridge cost (quotes shown upfront).
Q6: Is Phantom secure for multi-chain use? Should I use a hardware wallet?
A: Yes—non-custodial, seed phrase control, plus Ledger support. Enable transaction scans and 2FA. Start small and never share your seed phrase.
Q7: I don’t see my Sui or Base assets—what’s wrong?
A: Make sure the chain is toggled on in Active Networks. Restart/refresh the wallet—assets should appear automatically.
Conclusion
Phantom has fully evolved into a powerful multi-chain wallet. Enabling and switching between Ethereum, Base, and Sui takes just a few clicks: install → enable in Active Networks → select chain. The built-in cross-chain swapper makes moving funds feel effortless—no more juggling multiple wallets!
Data shows Base and Sui lead on low fees and speed, while Ethereum offers unmatched ecosystem depth. Together in Phantom, they give beginners (and pros) an easy way to explore Web3.
Next step: Head to phantom.app, back up your seed phrase securely, and test a small cross-chain swap (Ethereum → Base → Sui) with $1–5. Stay safe—DYOR and never share your seed!
