Wallets manage keys
A crypto wallet helps you manage the keys used to access and authorize activity for your addresses. Assets are recorded on the blockchain; the wallet is the tool you use to interact with them.

THE FUNDAMENTALS
What does "on-chain" mean?
A blockchain is a shared record maintained by a network of computers. A transaction is a request to update that record.
Addresses identify destinations
A public address can be used to receive assets on a compatible network. Always confirm the full address and network before sending.
Networks have different rules
Different blockchains are not automatically interchangeable. Check that the sending and receiving services support the same network.
TRANSACTION LIFECYCLE
How a transaction moves through a network
The exact process varies by blockchain, but most transactions follow a similar sequence.
1
Review and approve
Your wallet displays transaction details. Check the destination, network, amount, and any fee before approving.
2
Broadcast to the network
The signed transaction is sent to the network. A transaction ID (hash) may be provided so you can look up its progress in the relevant block explorer.
3
Wait for processing
Network participants process transactions under that chain's rules. Congestion, fees, and network-specific mechanisms can affect timing.
4
Verify the result
Use a trusted block explorer for the correct network and compare the transaction ID and destination.

A QUICK GLOSSARY
Four terms you'll see often
Learning the vocabulary makes wallet prompts and network explorers easier to understand.
Block
A batch of valid transactions added to a blockchain, linked to earlier blocks creating an ordered history.
Consensus
The rules a network uses to agree on which transactions belong in its shared history.
Network fee (gas)
A fee paid for processing a transaction. On some networks, "gas" measures the computational work required.
Smart contract
Program code that runs on a blockchain when its conditions are met. Review permissions carefully before approving.
Tip: A transaction marked "confirmed" has been included according to that network's rules. Some services wait for additional confirmations before treating a deposit as final.
COMMON TROUBLESHOOTING
Safe first checks
For a wallet or app issue, start here before taking further action.
Wallet not syncing
Check your internet connection and the wallet's official service-status page. Update only through the official app store or provider website.
Hardware wallet not detected
Use a known data-capable cable, try another USB port, and follow the manufacturer's official connection steps.
Transaction appears delayed
Look up the transaction ID on a block explorer for the exact network before taking further action.
Balance looks incorrect
Confirm the selected account, network, and asset, then refresh the wallet. Never enter your recovery phrase into an explorer.
SECURITY CHECKLIST
Protect your wallet
Keep these rules in mind every time you interact with a blockchain application.
KEEP THESE RULES IN MIND
- Keep your recovery phrase and private keys secret and offline; legitimate support should not need them.
- Verify website addresses, app publishers, network names, and transaction details before connecting or approving.
- Be cautious of urgent messages, unexpected support calls, giveaway promises, and requests to move funds to a "safe" wallet.
- Use official provider documentation and independently find contact details instead of using links in unsolicited messages.
- Remember that blockchain transactions are generally difficult or impossible to reverse once confirmed.
QUICK ANSWERS
Frequently asked questions
Can a confirmed transaction be reversed?
Usually, no. Many blockchain transactions are irreversible after confirmation. If you sent funds to the wrong address or network, contact the receiving service through its official channel; recovery is not guaranteed.
What is a recovery phrase?
It is a sensitive backup that may restore access to a wallet. Anyone who obtains it may be able to control the wallet. Store it securely and never share it or enter it into an unsolicited website.
Why does a transaction have a fee?
Many networks charge a fee to process or include transactions. The amount depends on the network and current conditions. Review the fee shown by your wallet before you approve.
What should I check before approving a transaction?
Confirm the network, destination, asset, amount, and fee. For a smart-contract interaction, read the permission request and make sure you reached the intended application using a trusted source.
Where can I learn more?
Start with documentation from the network or wallet provider itself. Useful references include Ethereum.org's wallet guide, its transaction overview, and the FTC guide to cryptocurrency scams.
Keep learning. Verify before acting.
