About Crypto Wallet QR Codes
The Bitcoin and Ethereum generators on this site each follow a specific, formally defined payment-request standard - BIP21 and EIP-681 respectively - with built-in support for structured amounts, labels, and messages that a compatible wallet reads and pre-fills automatically. This generator deliberately does none of that. It simply encodes a wallet address as plain text, with nothing structured or interpreted around it, which makes it the right tool for any cryptocurrency or chain that doesn't have its own dedicated payment-link standard, or for situations where a plain, shareable address is genuinely all you need. Scanning it doesn't open a payment app automatically the way a Bitcoin or Ethereum code does; it typically just displays the address as text, or lets the scanner copy it to paste manually into whatever wallet app they're actually using.
This is exactly the right choice for less mainstream chains and assets that don't have a dedicated generator elsewhere on this site - a Solana holder, a Litecoin holder, or someone holding a smaller or newer token can use this generator to share an address just as easily as if a purpose-built Solana or Litecoin type existed, since a plain address needs no special format to be useful. It also suits situations where you'd rather share an address for someone to send funds to manually, without triggering any kind of automatic payment flow - a donation address printed as signage at a meetup, a wallet address handed out on a card at a crypto conference booth, or an address posted for a community fundraiser where the exact amount contributed is left entirely up to the giver.
Because there's no built-in amount, label, or network field the way there is with the Bitcoin and Ethereum generators, the receiving payer has to enter every detail of the transfer themselves inside their own wallet app - which means genuinely more room for a manual mistake than a fully structured payment link provides. It's worth explicitly reminding anyone sending funds through a code like this to carefully double- and triple-check that the address displayed in their wallet after scanning matches exactly what they expected, and, critically, to confirm they're sending on the correct network for that specific asset, since many chains share superficially similar-looking address formats while being entirely incompatible with each other underneath.
That last point is worth dwelling on, since it's one of the more common and costly mistakes in the broader crypto space: sending an asset intended for one blockchain network to an address that's technically valid-looking but built for a different network entirely can result in funds that are extremely difficult, sometimes impossible, to recover. A generic address-only code like this one offers no built-in safeguard against that mistake the way a structured, chain-specific payment link might, so it's worth being explicit in any accompanying label about exactly which chain and asset the address is meant for.
As with any cryptocurrency transfer, transactions confirmed on a blockchain are generally final, with no dispute process, no bank to call, and no way to reverse a mistaken or fraudulent payment after the fact. This generator's simplicity - no payment-request standard, no amount pre-filled, no safety rails - makes that irreversibility even more worth taking seriously than it already is with the more structured Bitcoin and Ethereum types, precisely because there's less built into the code itself to catch an error before it happens.
Because this generator makes no assumptions about which chain your address belongs to, it's worth labeling that clearly anywhere the code is displayed - printed text right next to the code stating the asset and network, such as "Solana (SOL) only," removes the single biggest source of confusion for anyone about to send funds. A bare address with no such label leaves too much room for a sender to guess wrong about which network they should actually be using.
It's worth using this type sparingly and deliberately rather than as a default replacement for the Bitcoin or Ethereum generators - if you're specifically accepting BTC or ETH, those dedicated types offer real, useful structure this one intentionally lacks, including pre-filled amounts and built-in recognition by compatible wallets. Reserve the plain address format for exactly the cases it's built for: assets and chains that don't have a dedicated, structured option elsewhere on this site.
A common mistake worth naming: copying an address from a wallet app without checking for hidden characters or accidental extra spaces that a copy-paste operation can sometimes introduce, particularly when copying from a screenshot or a message rather than directly from the wallet itself. Generating the code straight from a fresh copy taken directly out of your own wallet app, rather than a screenshot or a note written down earlier, is the safest way to avoid this.
Storage of the address itself is worth a brief mention too, separate from the QR code: this type shares only a public receiving address, never a private key or wallet recovery phrase, so generating and printing one carries no risk to funds already held in the wallet - it functions purely as a receiving address for others to send to, in the same way sharing a bank account number for deposits doesn't expose the account to withdrawal.
