Why is there a minimum of about 1 ADA per payment?

Cardano ledger rules require every transaction output to contain a minimum amount of ADA (the min-UTxO value, roughly 1 ADA).

Which Cardano address should I share to receive payments?

Any receive address starting with addr1 from your wallet. It stays valid forever. Do not share stake1 keys or old Byron addresses.

Which Cardano address should I share?

Cardano wallets (Eternl, Lace, Yoroi, Daedalus) generate many addresses for one wallet, but any receive address you share stays valid forever and funds land in the same wallet — so you can safely publish one address on an invoice or a donation page. Avoid stake1… (a stake key, not a payment address) and old Byron addresses starting with Ae2 or DdzFF.

Matching payments to invoices on Cardano

Cardano has no memo or destination-tag field. To know which payment belongs to which order, merchants either derive a fresh address per invoice or use a unique amount per invoice (e.g. 45.500317 ADA). CryptoInvoice does the unique-amount matching, watches the chain and confirms after 6 blocks.

FAQ

Why is there a minimum of about 1 ADA?

Cardano's ledger rules require every transaction output to carry a minimum amount of ADA (the "min-UTxO" value, roughly 1 ADA). Requests below that cannot be paid.

Do all wallets understand web+cardano: links?

Eternl, Yoroi and several others do; some don't. If you're unsure, use the address-only QR and show the amount next to it.

Can I use a testnet address?

This tool is for mainnet (addr1…). Testnet addresses start with addr_test1….

Want the payment detected automatically?

A QR code shows where to pay. CryptoInvoice also watches the chain, marks the invoice paid, redirects the customer and calls your webhook — non-custodial, no KYC, 50 invoices a month free.
