Multi‑chain Wallet

1 min read
Pronunciation
[mul-tee-cheyn waw-let]
Analogy
Like a universal remote that can control your TV, stereo, and air conditioner without switching devices.
Definition
A cryptocurrency wallet that natively supports multiple blockchain networks and token standards, enabling users to manage assets across EVM, UTXO, and other chains within a single interface.
Key Points Intro
Multi‑chain wallets unify key management and UX across diverse networks.
Key Points

Network support: EVM, Bitcoin, Solana, Cosmos, etc.

Unified UI: Single balance view and transaction history.

Cross‑chain swaps: Integrated bridges or DEX aggregators.

Security: Single seed phrase with multi‑chain derivation paths.

Example
Phantom Wallet adds Ethereum support, letting users hold ETH, ERC‑20 tokens, and Solana SPL tokens in one app.
Technical Deep Dive
Wallet implements BIP‑39 seed, derives keys via SLIP‑44 paths for each chain. Integrates multiple RPC endpoints and uses chain adapters to format transactions and queries.
Security Warning
A compromise exposes all networks’ assets; use hardware wallet integration for high-value holdings.
Caveat
Complexity of supporting many chains can lead to inconsistent feature parity.
