A crypto wallet does not contain coins in the way a folder contains photographs. The network records balances and ownership. A wallet helps you inspect that record and authorize actions with the relevant signing credentials.
This distinction explains why replacing a phone can leave funds accessible, while losing recovery information can make them unreachable even though the blockchain still records them.
The address identifies an account
An address is information you can give someone so they can send assets to the intended destination. It is not the secret that authorizes spending.
The network matters alongside the address. Some networks use similar address formats, but a receiving service may support only particular assets and chains. A familiar-looking address does not establish that a deposit will be credited.
Ethereum’s wallet introduction describes the wallet as a tool for interacting with an account. The application displays network information and helps create and sign transactions.
Signing credentials authorize actions
For a conventional self-custody account, a private key is used to produce a signature. The network can verify that signature without learning the private key.
Many wallets generate a recovery phrase from which account keys can be derived. That phrase can control more than one account. Its role is different from the password you use to unlock a particular application on a device.
Account designs vary. Hardware wallets, smart-contract accounts and shared-control arrangements can use different signing and recovery methods. Read the documentation for the actual wallet rather than assuming every product has the same recovery phrase.
The app is an interface to network state
A wallet can query a network service to show balances and activity. If that service is unavailable or a token is not displayed, the interface may be incomplete even when the network record remains intact.
This is why an independent block explorer can be useful for checking an address and transaction. It is another view of the chain, not a place where you need to enter a recovery phrase.
An unfamiliar token appearing in a wallet also does not prove that you bought it or should interact with it. Public addresses can receive unsolicited assets. A displayed name or logo is not a reliable identity check.
Custody changes who controls recovery
With self-custody, the user controls the relevant signing arrangement. If all authorized recovery routes are lost, the wallet developer may have no way to restore access.
A custodial service usually controls the keys and records your entitlement in its own system. You sign in to an account, and the service processes withdrawals under its rules. Password recovery can restore account access, but it does not remove the service’s custody or availability risk.
Neither model should be judged only by convenience. Ask who can authorize a transfer, who can block access and what happens when a device or organization fails.
A signature can do more than send a token
Wallets can sign messages and authorize interactions with applications. Some permissions can remain after you close the website.
On networks that support token allowances, approving a contract to spend a token is different from sending one payment. The approved contract may retain that allowance until it is used or changed according to the token’s rules.
Our token approval guide explains why disconnecting a site does not necessarily remove on-chain spending permissions.
Test recovery before relying on it
Understand the wallet’s documented recovery procedure while the account is empty or contains only a harmless test amount. Keep recovery information out of websites, chat messages and ordinary support conversations.
When moving to another wallet application, confirm compatibility with the account type and derivation method. Importing a secret into more applications expands the places where it can be exposed.
The goal is not to memorize terminology. It is to know which information is public, which information authorizes action and which procedure restores access.
