Crypto Custody

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.

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.

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.

It provides two AML screening capabilities. Transaction screening (KYT) checks crypto transactions in real time so exchanges, PSPs, wallets and custodians can monitor activity as it happens, and address screening checks any wallet address against sanctions and fraud signals. Both return categorized compliance flags you can act on within your own workflows.

Yes. Address screening checks crypto addresses against OFAC SDN, EU and UN consolidated sanctions lists. It also flags exposure to fraud-related categories such as phishing, ransomware, darknet markets and mixers.

Yes. The Screen Transaction endpoint provides Know Your Transaction (KYT) checks for real-time monitoring, aimed at exchanges and custodians. This complements address screening so you can evaluate both counterparties and the transactions themselves.

Yes. The product states that every screening call is logged and retrievable, which supports audit trails for regulatory reporting.

Yes. Solana is a supported chain for Blockchain Events on both mainnet and devnet, alongside XRP and Kaspa. You can subscribe to events and receive callbacks for Solana activity through the same unified subscription flow used for the EVM and UTXO chains.

You can subscribe to confirmed coin (native) transactions, unconfirmed coin transactions, internal transactions, and token transactions for an address, as well as newly mined blocks. Confirmed coin, internal, and token transaction events also offer an each-confirmation variant that fires on every confirmation. For UTXO chains, callbacks report direction (incoming or outgoing) based on input/output address matching.

Events are delivered as HTTPS POST callbacks (webhooks) to a URL you register. The callback URL must use HTTPS and match a domain you verify in the Dashboard beforehand. You can optionally set a callback secret key so each request carries an HMAC-SHA256 x-signature header you can verify, and every callback includes an idempotencyKey so you can safely deduplicate.

CryptoAPIs retries failed callbacks with exponential backoff. Each callback allows a 5-second response timeout, and up to 5 retries follow roughly a 5, 10, 20, 40, and 80-minute schedule. If all retries fail, every subscription sharing that event type and callback URL is marked disabled, so you should monitor delivery and re-activate subscriptions as needed.
