What is Wallet Provider?

A wallet provider is any software or service that creates, stores, and manages private keys and enables blockchain interactions. Examples include MetaMask (browser extension), Ledger (hardware), Coinbase Wallet (mobile), and WalletConnect (connection protocol).

How does Wallet Provider work?

A non-custodial provider generates a private key from a seed phrase and stores it encrypted on your device.
When a dApp requests a transaction, the provider signs it without exposing the key.
Custodial providers hold keys on their servers and sign on your behalf.

Why does Wallet Provider matter?

The provider determines your security model. Non-custodial providers give you full control and full responsibility.

Custodial providers are more convenient but introduce counterparty risk.
