Good questions.
Clear answers.

Crypto is a broad name for digital assets whose ownership or transfer follows cryptographic and network rules. It does not mean that every asset is safe, useful, or valuable.

Participating computers check an ordered transaction record using shared network rules. A public record does not reveal every real-world fact about the people or assets represented.

No. A database controlled by an accountable operator can be simpler and easier to maintain. A shared ledger makes sense only when its benefits justify its costs and trade-offs.

No. An asset may be held by a service for you, or you may control it through self-custody. Custody determines who can authorize a transfer and what recovery might be available.

Names and logos can be copied. Check the intended network and its token mint or contract using an independent trusted source before taking action.

Share the right public receiving address and network through an appropriate channel. Never share a recovery phrase, private key, password, or unexpected signature request.

A search placement, review, or logo does not prove who published an app. Start from the wallet maker’s independently verified official site and follow its link to a store or extension.

No legitimate support interaction should require sending your recovery phrase to a person, form, or website. Anyone who obtains it may control the wallet.

No. Connecting and signing are separate actions. Read each message, transaction, or permission request independently; disconnect if the site or request surprises you.

No. The lessons and practice exercises require no token purchase, wallet connection, signature, or sharing of private information.

No. Solana is the network; SOL is its native token. SOL is commonly used for fees, while separate tokens on Solana have their own identifiers.

No. A mint identifies an issued token. A holder's balance is recorded in a token account associated with that mint and an owner.

No. Devnet is for testing and its test tokens are not production assets. A Devnet exercise proves nothing about a funded Mainnet swap.

Transactions pay network fees, commonly in SOL. Some account operations have additional conditions or costs; inspect the actual wallet prompt.

No. Asset identifiers, supported wallets, and transfer routes are network-specific. Confirm the network and actual asset identifier before choosing a route.

Verify the destination, actual asset, network, and the receiving service's support for that network. A similar-looking address does not make two networks interchangeable.

No. A test checks one address and route under particular conditions. The next transfer can still have a different fee, network, or account issue.

An explorer can use it to show a transaction on a selected Solana cluster. Check the cluster and result, and remember public signatures can reveal activity.

Check the signature, selected cluster, and latest explorer status. Avoid resubmitting until you understand the first transaction; retries can create a second transfer.

No. Names and amounts do not make networks interchangeable. The receiving service must support the actual network and token that you send.

Jupiter Spot is a Solana trading interface that presents token-swap routes. A changing quote is not a guaranteed result, and a working route does not prove that a token is safe.

A connection lets the app access limited wallet information. A signature authorizes a particular request. Review each wallet prompt, and reject unexpected actions.

Check both assets and amounts, the route, estimated output, price impact, slippage, displayed fees, and wallet request. A quote may change before execution.

No. Price impact estimates how a trade affects price in its liquidity; slippage tolerance is an execution boundary for quote changes. Neither measures every risk.

Pause and check both mint addresses, the route, amount, output, fees, and price impact. Cancel rather than raise tolerance or approve a result you do not understand.

Verify the site, wallet request, input, output mint, amount, quote conditions, and displayed fees. Declining is always valid when a prompt differs from what you intended.

First inspect its wallet and explorer status, signature, and fees. Repeated submissions may create more transactions or fees; stop if the displayed state is unclear.

It displays reported network data for an address or transaction. It cannot alone verify an issuer's identity, off-chain backing, rights, or future value.

No. They are separate projects. A ticker, logo, search result, or route is not proof; check the Solana mint against an independent trusted source.

A public address does not prove the real-world identity behind it. Wallet labels can be incomplete or misattributed; treat identity claims as unverified without independent evidence.
