UtxoContext
UtxoContext allows you to track address activity on the Kaspa network. When an address is registered with UtxoContext, it aggregates all UTXO entries for that address and emits events whenever any activity occurs on these addresses.
The UtxoContext constructor accepts the IUtxoContextArgs interface, which can optionally include an id parameter. If supplied, this id will be included in all notifications emitted by the UtxoContext and in the ITransactionRecord object when transactions occur. If not provided, a random id will be generated. This id typically represents an account id in the context of a wallet application.
UtxoContext maintains a real-time cumulative balance for all addresses registered with it and emits balance update notification events when the balance changes.
UtxoContext can also be supplied as a UTXO source for the transaction Generator, allowing the Generator to create transactions using the UTXO entries it manages.
IMPORTANT
UtxoContext is intended to represent a single account. It is not designed to serve as a global UTXO manager for all addresses in a large wallet (such as an exchange wallet). For such use cases, it is recommended to perform manual UTXO management, as described in the Direct Node RPC section.
NOTE TO EXCHANGES
If you are building an exchange wallet, it is recommended to use UtxoContext for each user account. This allows you to track and isolate each user's activity (address set, balances, transaction records).
