Hardware-wallet workflows

Hardware-backed security

Addresses

0x and sei1 addresses

Sei exposes both EVM (0x) and Bech32 (sei1) address formats for an account. Until they are associated, EVM and Bech32 balances may appear separately. Account association links them so balances and history stay coherent.

Address types

EVM (0x): 20-byte hex, used by EVM tooling
Bech32 (sei1): Sei-native address format
Association: One-time link between formats
