The user is asking about addresses for one single wallet.

<p>We are curious how many receive addresses can possibly be generated for a given wallet?</p>

According to [BIP44](https://github.com/bitcoin/bips/blob/master/bip-0044.mediawiki), which Cardano wallets are using, the index number of addresses is capped at 32 bits.

So you will be able to generate 4 294 967 296 addresses for one single HD wallet. The first half is reserved for non-hardened derivation and the other half is reserved for hardened derivation.

Apparently the [most recent wallet addresses (Shelley era) are in BECH32 format](https://forum.cardano.org/t/addresses-in-cardano/45528), which support [2^160 number of addresses](https://bitcoin.stackexchange.com/questions/69512/does-the-bech32-address-format-decrease-bitcoins-possible-address-count#:%7E:text=There%20are%20exactly%202%5E160,we%20keep%20using%20RIPE%2DMD160). So, practically unlimited.
