Conflux Address Formats

Why two address formats

Conflux Network has two execution environments under one consensus. Each uses a different address format because they are different VMs underneath:

• Core Space uses Conflux's CIP-37 base32 address format with built-in error detection. Mainnet addresses start with cfx: (e.g., cfx:aakd0e7yh3kabskanjugzaadfpxbhe8tj9ymbn0ubr).
• eSpace uses Ethereum's standard EIP-55 hex format. Addresses start with 0x (e.g., 0x1B3F4C...).

The address format itself encodes which space the address belongs to. Sending to the wrong format fails at the network level — funds are not lost, the transaction is rejected.

How to recognize each format

What this means for sending

• Sending to a cfx: address sends within Core Space. Use Core Space CFX.
• Sending to a 0x address sends within eSpace. Use eSpace CFX.
• Cross-space sends require bridging — see Move CFX between Core and eSpace.

Conflux Wallet labels every address by space when you copy or paste, and warns you before any cross-space mistake. The address format itself prevents the most common error.

Hex address (0x...) caveat

The eSpace 0x... format is the same format Ethereum uses. Sending Ethereum to a Conflux eSpace 0x address sends Ethereum to a different chain entirely — Ethereum and Conflux are different networks even though they share address format. Always check which network you're on, especially when copying addresses across wallets.

Cross-space mapping

A Core Space address cfx:aa... and an eSpace address 0x1B3F... derived from the same seed phrase are DIFFERENT accounts. They are linked by your wallet, not by the protocol — your seed phrase generates both. To move funds between them, use the cross-space bridge.
