There is no chargeback, no support desk that can reverse one, and no requirement that an address belong to anybody in particular. That makes the moment you paste a destination address the single riskiest step in owning crypto.\u003C\u002Fp>\u003Ch2>How addresses get swapped\u003C\u002Fh2>\u003Cp>Malware that watches the clipboard replaces a copied address with the attacker's own, betting you will not read what you pasted. Address poisoning works differently: the attacker sends you a tiny or zero-value transfer from an address whose first and last characters match one you have used, so that a later copy from your transaction history picks up theirs. Both attacks target the same habit — checking only the beginning and end of a long string.\u003C\u002Fp>\u003Ch2>The check that works\u003C\u002Fh2>\u003Cp>Compare the whole address, not the first four and last four characters. Read it in chunks against the source you trust, or paste it into a text field and compare visually side by side. Where the destination supports it, use a name or identifier the network verifies rather than a raw string. Always copy from the withdrawal page of the receiving service, never from a chat message, an email or your own transaction history.\u003C\u002Fp>\u003Ch2>Check the network too\u003C\u002Fh2>\u003Cp>The same address format is used by several networks, and sending an asset over a network the recipient does not support is a common way to lose it. Confirm the network on both sides, and check that the asset you are sending is the one the deposit address expects.\u003C\u002Fp>\u003Ch2>Send a test transaction\u003C\u002Fh2>\u003Cp>For any transfer you would mind losing, send a small amount first, wait for it to arrive and be credited, then send the rest. The fee on the test is the cheapest insurance in crypto. On networks that require a memo or tag, the test also proves you filled that field correctly — a deposit without one can take weeks of support to recover, if it is recoverable at all.\u003C\u002Fp>\u003Ch2>The bottom line\u003C\u002Fh2>\u003Cp>Verify the full address, confirm the network, and prove the route with a small transfer before you commit the balance.\u003C\u002Fp>",[11,17,22,26,27,32,36,40,44,49,53,57,61,65,69,73,77,81,85,89,93,97,101,105,109,113,117,121,125],{"slug":12,"title":13,"excerpt":14,"topic":15,"updated_at":16},"an-etf-share-or-the-coin-itself","An ETF Share or the Coin Itself","Both track the same price and they are not the same asset.
