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.
/ quick answer
The seed (BIP-39 mnemonic) deterministically generates all addresses and keys in a wallet. It is a bearer secret: it cannot be revoked, rotated for existing addresses, or recovered if lost. Store it offline, never in a screenshot, cloud note or chat, and treat any site or 'support agent' asking for it as an attack.

What is an example of Seed Phrase?
Restoring the same accounts on a new device by entering the 12-word phrase — and losing them permanently if the phrase was only stored in a photo on a broken phone.

Related concepts
The vocabulary this page depends on.
- →Web3 Wallet
A Web3 wallet stores your keys and signs transactions, letting you hold assets and connect to on-chain applications without an intermediary.
- →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.
- →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.
- →DeFi
DeFi is financial infrastructure built as open smart contracts — lending, trading, staking and derivatives that anyone can use or compose.
Related workflows
Turn this into a repeatable process.
- →AI Crypto Research Workflow
A repeatable research loop: turn a question into market data, on-chain evidence and a written risk view before any position is considered.
- →Track A Whale Wallet
Monitor a single large address correctly: separate real position changes from custody moves before drawing any conclusion.
- →Automated Crypto Alerts
Define the conditions that would change a decision, monitor them automatically, and receive one clean notification instead of watching charts.
- →AI Agent + Web3 Execution
Give an AI agent on-chain capability safely: read freely, propose openly, and sign only inside hard-coded limits.

Related prompts
Reusable prompts for this job.
- →Recurring Crypto Workflow Prompt
Specifies a safe recurring on-chain automation with spend caps, idempotency, failure handling and a kill switch.
- →Crypto Market Analysis Prompt
Produces a structured market brief: regime, liquidity conditions, sector rotation, catalysts and what would change the view.
- →Crypto Risk Analysis Prompt
Runs a pre-mortem on a position or protocol: enumerates failure modes, likelihood, impact and observable early warnings.
- →Crypto Agent Design Prompt
Specifies an AI crypto agent's tools, permissions, guardrails and evaluation before a single line is written.
Related use cases
How people apply it, and what came out.
- →Use DeFi With A Web3 Wallet
A first-time DeFi user moved from an exchange to self-custody with a test-transfer routine and a 2% allocation cap, avoiding two protocol failures.
Comparisons & alternatives
Pick between the options.
- →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.
- →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.
- →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.
