Frequently Asked Questions

HD Wallets

Which blockchains does the Crypto APIs HD Wallets Management (xPub sync) API support?

The HD Wallet (xPub/yPub/zPub) sync API supports the EVM chains (such as Ethereum, Ethereum Classic, BNB Smart Chain, Tron), the UTXO chains (Bitcoin, Bitcoin Cash, Litecoin, Dogecoin, Dash, Zcash), and XRP. You import an extended public key and Crypto APIs derives and syncs its addresses and transactions for you.

Does the HD Wallets Management API support Solana?

No. HD wallet (xPub/yPub/zPub) sync is not available for Solana. HD wallet coverage is limited to the EVM chains Ethereum, Ethereum Classic, BNB Smart Chain and Tron, the six UTXO chains (Bitcoin, Bitcoin Cash, Litecoin, Dogecoin, Dash, Zcash) and XRP. Solana is supported by other Crypto APIs products such as transactions data and blockchain events, but not by the HD wallet endpoints.

What can I do with a synced xPub through the HD Wallets API?

Once you sync an extended public key you can list all your synced HD wallets, pull the wallet's aggregated assets and balances, retrieve wallet details, and list the wallet's transactions across all derived addresses through a single integration. The sync monitors every derived address for you, so you do not have to track individual addresses manually. Syncing and deleting an xPub each carry a subscription cost, and monitored addresses incur a daily monitoring tax.

Can I derive addresses from an xPub without calling the API or exposing keys?

Yes. Crypto APIs provides address-derivation utilities in the blockchain tools family that generate child addresses from an extended public key for EVM chains, the UTXO chains and XRP. Because HD wallets use extended public keys, derivation and wallet syncing never require your private keys. This lets you generate deposit addresses and reconcile them against a synced wallet.

Is there a free tier, and how is HD wallet usage billed?

Every API request consumes credits, with the exact amount returned in the x-credits-consumed response header and the cost varying by endpoint and blockchain. HD wallet asset and transaction reads on UTXO chains are among the heavier calls (roughly 520-530 baseline credits), and a synced xPub also adds a per-subscription cost plus daily monitoring taxes per derived address. After your monthly credit allocation is exhausted, usage continues automatically under pay-as-you-go billing. The marketing page does not state a specific free-tier allowance.
