This guide is educational, not personalized financial, legal or security advice. A checklist reduces avoidable mistakes; it cannot make a transaction risk-free.
An address identifies a destination; private signing material authorizes actions; an app or provider password may control access; and a recovery phrase may restore multiple keys in wallets that use one. Wallet behavior varies. Public address sharing can expose activity.
- A public address identifies an account or destination. Confirm the supported asset, network and complete receiving details; public sharing can reveal activity.
- A private key is secret signing material for key-based accounts. Do not share it; a signature may be checked publicly without revealing the key.
- A wallet password may unlock an app or encrypted file; an exchange password protects provider login. Neither description is universal.
- A recovery phrase is separate and may restore multiple keys in wallets that use one. Never give it to a payer, support agent or learning site.
A payer asks for the receiving address, then a support message asks for your app password and recovery phrase. Which details can be relevant to receiving, and which secrets should never be sent?
These credentials answer different questions
A public address is a destination or account identifier that can usually receive funds. A private key is signing material that can authorize actions for the corresponding account. A wallet password may unlock a local app or encrypt a file, while an exchange password protects access to a provider account. None of these is a substitute for the others.
A recovery phrase is a separate, broader secret in wallets that use one: it can derive or restore multiple private keys. Treat it as more powerful than an individual address and at least as sensitive as a private key. Account designs vary, so follow the documentation for the exact wallet or provider instead of assuming that every “password” has the same authority.
What can be shared, and what should not be
A payer may need the supported asset, network, public receiving address and sometimes a memo or destination tag. They do not need your recovery phrase, private key, wallet unlock password or exchange login. A read-only portfolio tool should not need signing material. If a site asks for a phrase to verify a payment, it is asking for far more authority than the task requires.
Public does not mean consequence-free. An address can expose balances, counterparties and transaction history, and reusing it can make activity easier to link. Share only what the payment requires and consider the privacy implications of posting an address publicly.
A classification exercise
Label five fictional values: public destination, public transaction reference, login credential, signing secret and recovery secret. Then write the action each value permits. This makes it harder for a support impersonator to blur a login request into a wallet request. StonkBuilder Learn never needs any of the secret values. For the next step, read how to check that a wallet app is genuine.
Check your understanding.
What does a payer ordinarily need?
A correct answer records local learning progress, not a qualification or proof of financial readiness.
Put this lesson in context
Start with who controls the keys. Continue to recovery and backup planning before connecting an application.
