1. What is multi-chain address derivation?

Multi-chain address derivation is the process of generating cryptocurrency addresses for multiple blockchain networks from a single private key or mnemonic phrase. For EVM-compatible chains, the same private key produces the same address across all networks, making it easier to manage assets across different blockchains.

2. How does it work?

EVM-Compatible Chains

Ethereum Virtual Machine (EVM) compatible chains use the same address format. This means your private key or mnemonic phrase generates the same address across Ethereum, BSC, Polygon, Arbitrum, Optimism, Avalanche, and Base.

BIP44 Derivation

BIP44 is a standard that defines how to derive multiple addresses from a single mnemonic phrase. The derivation path format is: m / purpose' / coin_type' / account' / change / address_index. For Ethereum, coin_type is 60.

3. Examples

Mnemonic to Address

Mnemonic: duty clump embody almost vanish excite same mass
Path: m/44'/60'/0'/0/0
→ Address: 0xFA5d2937796725F25Dc867b80436a8DE75Dc372F0
(Same address on Ethereum, BSC, Polygon, Arbitrum, Optimism)

Private Key to Address

Private Key: 0x39d81618ff2db2922a9a87dafb9d17bcb0300c234
→ Address: 0xb67C268fAC7C2Fba5eD461C8085008D75F5Db8A70
(Works across all EVM-compatible chains)

Multiple Addresses from Same Mnemonic

Same mnemonic with different paths:
m/44'/60'/0'/0/0 → 0xFA5d2937796725F25Dc867b80436a8DE75Dc372F0
m/44'/60'/0'/0/1 → Different address
m/44'/60'/0'/0/2 → Another different address
