Everything about wallet
14 connected nodes across dictionary, workflows, comparisons, prompts, tool stacks and use cases.
Web3 Wallet
A Web3 wallet stores your keys and signs transactions, letting you hold assets and connect to on-chain applications without an intermediary.
Self-Custody
Self-custody means you control the private keys to your assets, so no company can freeze, lend out or lose them on your behalf.
Seed Phrase
A seed phrase is the 12–24 word backup from which every private key in a wallet is derived — whoever holds it holds the wallet.
Private Key
A private key is the secret number that authorises transactions from an address; the public address is derived from it, never the reverse.
Token Approval
A token approval grants a contract permission to move your tokens — persistent, often unlimited, and the most common source of avoidable losses.
Multichain
Multichain means operating across several networks at once — more opportunity, more surfaces to secure and more addresses to monitor.
Account Abstraction
Account abstraction turns a wallet into a programmable smart account: custom signing rules, spending limits, sponsored gas and batched actions.
Hot Wallet vs Cold Wallet
Hot wallets trade convenience for exposure; cold wallets trade friction for a signing key that never touches an internet-connected device.
Custodial vs Self-Custody
Custody choice is a swap between counterparty risk you cannot control and operational risk you can.
Web2 Apps vs Web3 Apps
Web2 apps authenticate with accounts and store state on private servers; Web3 apps authenticate with a wallet signature and keep state on a public chain.
MetaMask vs OKX Web3 Wallet
MetaMask is the EVM default with the widest DApp support; OKX Web3 Wallet bundles multi-chain coverage, a DEX aggregator and exchange integration in one app.
Phantom vs OKX Web3 Wallet
Phantom is a Solana-first wallet with best-in-class UX on that ecosystem; OKX Web3 Wallet is a generalist multi-chain wallet for users spread across networks.
Rabby vs OKX Web3 Wallet
Rabby is the safety-focused EVM wallet with pre-transaction simulation; OKX Web3 Wallet trades some of that depth for multi-chain breadth and built-in trading.
