Picking the Wrong Network Breaks a CFX Wallet
Nearly every tutorial on setting up a CFX wallet misses the one tip most likely to cause tears. Conflux has two network environments, and sending tokens to the incorrect network can make it appear that funds have vanished into thin air. As of this writing, CFX is priced at $0.056 on CFX CoinGecko. Over 400 million successful transactions have been made on the chain, and the number of new participants joining the Conflux Network each day is on the rise.
This post walks through how to set up Fluent Wallet, how to configure MetaMask for eSpace, and the mistakes that can leave users with tokens stuck on the wrong network. The issue is not that wallet setup is difficult. The issue is that Conflux's dual-network system is a trap for the unsuspecting before they click "Send".
Core Space and eSpace Share One CFX Token
This is something new users should understand long before attempting to install anything. The Conflux Network has two parallel execution environments running at the same time: Core Space and eSpace. Core Space is native to Conflux and uses its native address format ("cfx:" or "cfxtest:"). eSpace is the EVM-compatible execution environment that uses Ethereum-style addresses ("0x"). CFX is the native token residing on both sides of the network.
You can freely send your CFX back and forth between the two spaces by interacting with a built-in contract on the network called CrossSpaceCall. However, you cannot send Core Space tokens directly to an eSpace address, and you cannot send eSpace tokens directly to a Core Space address. This has been the number-one source of confusion in CFX crypto forums and support channels.
To elaborate for the small handful of people who may actually be asking what is CFX from a wallet perspective: it depends what world they want to exist in. If they want to play in the DeFi world (the stablecoin ecosystem) with tokens like USDT and AxCNH, then they're in eSpace. For 99% of newcomers, it's best to start there. Wallet choice becomes obvious from that. Fluent Wallet supports both spaces natively, but MetaMask can only connect to eSpace.
| Core Space | eSpace | |
|---|---|---|
| Address format | cfx: / cfxtest: | 0x (Ethereum-style) |
| Wallet support | Fluent Wallet | Fluent Wallet and MetaMask |
| Best for | Native Conflux dApps | DeFi, stablecoins, bridges |
| Native token | CFX | CFX |
| Chain ID | Not applicable | 1030 mainnet / 71 testnet |
Core Space and eSpace run in parallel on Conflux and share the same CFX token, but their addresses are not interchangeable.
Setting Up Fluent Wallet in Under Five Minutes
Fluent Wallet is the native browser extension provided by Conflux. Because it handles Core Space (cfx:) and eSpace (0x) addresses interchangeably within the same app, Fluent should be your clean start if you plan to use both environments at any point in the future.
Step one: Open Chrome, Brave, or Edge and navigate to the Chrome Web Store. Search for "Fluent Wallet", confirm the publisher is named "Conflux", click "Add to Chrome" and confirm the extension permissions. Step two: An icon for the extension should now appear in your browser toolbar. Clicking it opens a setup wizard. Select "Create a New Wallet". Step three: Choose a secure password. This password encrypts the wallet data stored locally on your browser and serves no other purpose. If your seed phrase is compromised in any way, this password will do you no good. Step four: The wallet provides a 12-word seed phrase. Write down this phrase on a piece of paper. Do not screenshot it. Do not copy and paste it into a note app. Do not email it to yourself.
After confirming the seed phrase, Fluent automatically generates a Core Space address (starts with cfx:) and an eSpace address (starts with 0x). You can switch between them using the network selector in the top-left corner of the extension at any time. Withdrawals from most exchanges will send funds to your eSpace address (starts with 0x), including Kraken, which added CFX in February 2026.
Important: your Core Space address and your eSpace address are NOT the same address. Even though both are derived from the same seed, sending CFX to your Core Space address from an exchange that formats withdrawals as eSpace will fail. If there are no safeguards in place to prevent it, the funds go to the wrong place.
Connecting MetaMask to Conflux eSpace
If you don't want to install another extension, you can connect MetaMask directly to eSpace. MetaMask doesn't support Core Space at all, so this only connects you to the EVM-compatible side of things. But that's good enough for the roughly 99% of people who just want to use everything on eSpace: the DeFi protocols, the cross-chain bridges that deposit to Stargate Finance and Orbiter Finance, the stablecoin lending markets, all of it. If you've added a custom network before, like in this 90-second Arbitrum wallet setup, the flow will feel familiar.
Open MetaMask and click the network dropdown menu at the top. Click "Add Network" then "Add a network manually". Network Name: Conflux eSpace. New RPC URL: https://evm.confluxrpc.com. Chain ID: 1030. Currency Symbol: CFX. Block Explorer URL: https://evm.confluxscan.org. Click "Save" and you'll be connected to Conflux eSpace on MetaMask. You'll know it worked because it will show "Conflux eSpace" under the network name and "CFX" under the currency symbol. These exact values come straight from the official Conflux endpoint docs, which is worth bookmarking.
As always, send yourself a small test transaction before bridging any significant amount, just to be sure everything works. Right now bridging fees are 0% via Meson if you're coming from BNB Chain, Arbitrum, Optimism, and Avalanche for both USDT and USDC, so test transactions will basically be free aside from gas worth a few cents. Anyone who has watched the Conflux price knows the token is cheap enough that test transactions won't cost you anything.
Mistakes That Cost People Their Tokens
Three miscues account for the majority of CFX wallet problems posted in community forums and across social media. Error one: sending CFX to a Core Space address from an exchange that only supports eSpace. To unpack that: most popular exchanges send CFX using the eSpace network. If a person copies their Core Space address (begins with "cfx:") and pastes it into the withdrawal field on an exchange, the transaction will likely be rejected or sent to pending purgatory. Check the address format the exchange uses before you hit send. Kraken's listing supports eSpace as well.
Error two: entering the wrong Chain ID on MetaMask. When adding the network, the Chain ID for Conflux eSpace mainnet is 1030 and testnet is 71. If entered incorrectly, MetaMask redirects to a completely different network and any transactions will either fail or be sent who knows where. Just double-verify you have the right number. It won't bite.
Error three: mixing up CFX on Conflux with wrapped or bridged tokens on other blockchains. If you see trading pairs such as CFX/USDT on an exchange, do not assume CFX exists on Ethereum, BSC, or any other chain. It does not. There are wrapped versions of CFX, but to use the bridged version on the Conflux chain you must follow additional steps to unwrap. The newest wrinkle in CFX news is the arrival of cross-chain bridges and the need to distinguish wrapped tokens from bridged tokens of the original asset.
Backing Up a CFX Wallet Without Cutting Corners
Your seed phrase is your wallet. Not your password. Not the browser extension. Not your computer. If something happens to the browser, you can restore using the seed phrase. If your laptop dies, you can restore using the seed phrase. Even if Chrome deletes your extension data during an update, you can restore using the seed phrase. If you lose your seed phrase, you cannot restore. There is no customer support phone number. There is no password recovery flow.
Write down the 12 words on a piece of paper. Put that paper in a physically secure location. A fireproof safe is good. A safety deposit box is also good. A sticky note on your monitor is not. If you are storing any significant amount of CFX, or actively trading on DeFi protocols in eSpace, consider a second backup in a separate physical location. That's just good redundancy.
Never input your seed phrase into any website, form, or app that promises to "verify" or "validate" your wallet. That is by far the most common form of phishing on every blockchain network, not just Conflux. As the wallet-security community keeps repeating, and as this rundown of common safe-wallet myths lays out, Fluent Wallet and MetaMask will never ask you for your seed phrase after you first create the wallet. If you see such a prompt, close the website. It's a phishing scam.
Finally, users following the CFX price or reading about Conflux's proposed hardfork (which bundles eight CIPs including CIP-7702) should also watch for upgrades required by wallet software. Earlier this year the Conflux network shipped its v3.0.3 node release, which patched seven bugs across its RPC services and consensus logic. Node upgrades alone do not affect browser wallets. However, interactions with dApps may start to break if the network changes and the wallet's RPC endpoint isn't kept up to date. It's worth periodically verifying that the RPC URL inside MetaMask still resolves.
The Wallet Setup Is Just the Starting Line
Setting up a CFX wallet correctly is not too difficult once you understand the Core Space versus eSpace difference Conflux has compared to single-environment chains like Ethereum or BSC. Fluent supports both environments natively, and MetaMask works with eSpace once you manually add the network. Fluent prevents the normal errors (wrong address format, wrong Chain ID, native versus bridged token confusion) through a single 30-second address and network verification before sending any transaction.
With eight improvement proposals activating at Conflux's next hardfork and the token priced at a level where network fees are virtually non-existent, there's no better time to make a wallet and get familiar with sending small amounts. The network just handled over 400 million transactions without congestion. The faucets work. Everything is built. The only question mark is whether you've set your address correctly on the correct network, which this article just walked you through. For anyone weighing the Conflux Network token as a longer-term hold, the wallet is step one.
