Authorization
A digital signature provides evidence that the required key authorized a transaction. It does not prove that a recipient is trustworthy or that the person signing understood the request.

Understand what happens after you press send
Cryptocurrencies use digital signatures and shared rules to record who can transfer value. Your wallet helps you authorize an instruction. The network determines whether that instruction is valid under its rules.
Bitcoin and Ethereum illustrate this process, but they do not use identical systems. Understanding the distinction between a wallet, a network and a service account makes everyday transaction messages easier to interpret.

01 / Separate the tools
A wallet displays balances and helps create transactions. With a wallet you control yourself, private keys authorize spending. A receiving address identifies a destination; it is not the secret needed to spend from it. A recovery phrase can restore access in many wallet designs and must stay private.
Installing another wallet does not create another copy of your assets. The assets are represented in network records. Compatible software can provide a different interface to the same account or keys, but importing a recovery phrase into an untrusted application can expose control.
A custodial service may show your holdings in its own account system while it manages the underlying keys. Moving value inside that service does not necessarily create a public blockchain transaction. A withdrawal request is an instruction to the service, not proof that a network transfer has already occurred.
Ask which record you are looking at: an account credit, an order, a withdrawal request or a confirmed network transaction. A label such as “pending” only makes sense when you know the system that produced it.
02 / Follow the instruction
A digital signature provides evidence that the required key authorized a transaction. It does not prove that a recipient is trustworthy or that the person signing understood the request.
Network software checks the instruction against its rules. In Bitcoin, nodes reject invalid spending rather than accepting it simply because a miner included it in a block.
Consensus rules help participants agree on transaction history. Bitcoin uses proof of work. Ethereum uses proof of stake, with validators committing ETH under rules that include rewards and penalties.
Bitcoin records transfers under its own protocol. Ethereum also executes smart contracts, programs that can update application state. ETH is Ethereum's native asset and pays network execution fees. A token running on Ethereum can have different rules and risks from ETH itself.
For an Ethereum transaction, a wallet signs an instruction and broadcasts it. The instruction can transfer ETH or interact with a contract. It requires network processing and a fee. A valid contract interaction can still produce an unwanted financial result, so a successful network status is not a safety endorsement.
This is a simplified introduction. Other networks, additional layers and wallet designs can use different rules. A ticker symbol alone does not establish which network a receiving service supports.
03 / Read the request before approval
Use the receiving service's current deposit instructions. Confirm the exact asset, network and any required reference. Similar names and familiar address formats do not prove compatibility.
For a payment, verify the full destination and amount. For an application, understand the contract action and permissions shown by the wallet. Stop if the request differs from your intent.
A network processing fee, a trading charge and a service withdrawal charge can represent different costs. Read the complete quote and expected amount received. For company fees, use the current account quote.
Keep the service receipt and, when available, the transaction identifier for the correct network. A service request can remain under review before broadcast. After broadcast, network inclusion and the recipient's crediting policy are separate steps.
Bitcoin confirmations do not arrive on a guaranteed schedule. A public record also does not mean anonymity: transaction information can be connected with information disclosed elsewhere. Protect your privacy as well as your recovery information.
For a practical next step, read how to verify a Bitcoin wallet address and how to buy Bitcoin safely. Understanding the technology does not remove price volatility or the possibility of loss.
04 / Common questions
A wallet manages access and shows information from network records. Copying its application files does not create additional spendable coins.
No. A purchase can update an exchange's internal account records. A later withdrawal may create a separate network transaction.
No. Confirmation describes network processing. It does not verify a merchant's identity, promises or willingness to provide a refund.
Bitcoin has no central support desk that can undo a settled payment. A recipient may send a separate refund, but you should not assume recovery is possible.
