Check a donation address

Check the address your wallet shows (after scanning or pasting) in a view-only copy of the CCS wallet, made from its public address and view key (where they were published; take them from there, not from this page):

• Address: 9xExampleWalletAddress
• View key: 0123456789abcdef

How to make a view-only wallet (it needn’t sync). Then ask it with monero-wallet-rpc v0.18.4.1 or later (reference): first a bigger subaddress lookahead (the donation addresses are past the first 200), then the address:

set_subaddress_lookahead  {"password": "<your wallet's password>", "major_idx": 1, "minor_idx": 20000}
get_address_index         {"address": "<the address>"}

An index: it is the CCS wallet’s. “Address doesn’t belong to the wallet”: do not send, and tell the CCS maintainers.
