@requestnetwork/payment-detection

@requestnetwork/payment-detection is a typescript library part of the Request Network protocol. It contains client-side payment detection for all supported payment networks.

Payment and Refund detections

If a payment network has been given to the request, the payment detection can be done.

From the information provided in payment network, the library will feed the property balance of the request with:

balance: the sum of the amount of all payments minus the sum of amount of all refunds
events: all the payments and refunds events with the amount, timestamp etc...

The payment networks available are:

Types.Payment.PAYMENT_NETWORK_ID.BITCOIN_ADDRESS_BASED ('pn-bitcoin-address-based'): handle Bitcoin payments associated to a BTC address to the request, every transaction hitting this address will be consider as a payment. Optionally, the payer can provide a BTC address for the refunds. Note that the addresses must be used only for one and only one request otherwise one transaction will be considered as a payment for more than one request. (see the specification)
Types.Payment.PAYMENT_NETWORK_ID.TESTNET_BITCOIN_ADDRESS_BASED ('pn-testnet-bitcoin-address-based'): Same as previous but for the bitcoin testnet (for test purpose)
Types.Payment.PAYMENT_NETWORK_ID.ERC20_ADDRESS_BASED('pn-erc20-address-based'): Same as BITCOIN_ADDRESS_BASED, for ERC20 payments.
Types.Payment.PAYMENT_NETWORK_ID.ERC20_PROXY_CONTRACT('pn-erc20-proxy-contract'): uses an intermediary contract to document which request is being paid, through the PaymentReference. (see the specification)
Types.Payment.PAYMENT_NETWORK_ID.ETH_INPUT_DATA('pn-eth-input-data'): uses the transaction input data to pass the PaymentReference. (see the specification)
Types.Payment.PAYMENT_NETWORK_ID.DECLARATIVE('pn-any-declarative'): a manual alternative, where payer can declare a payment sent, and payee can declare it received, working for any currency. (see the specification)
