decodePayment

decodePayment(code): { amount?: number; identifier: string; token: string; } | undefined

Defined in: packages/ledger-icrc/src/utils/payment.utils.ts:26

👀 This feature is currently in draft. You can find more information about it at https://github.com/dfinity/ICRC/issues/22.

A naive implementation of a payment parser. Given a code, the function attempts to extract a token name, account identifier (textual representation), and an optional amount.

If the code doesn’t match the expected pattern, undefined is returned for simplicity. Similarly, if an optional amount is provided but it’s not a valid number, the parser will not throw an exception and returns undefined.

Please note that this function doesn’t perform any validity checks on the extracted information. It does not verify if the token is known or if the identifier is a valid address.

urn            = token ":" address [ "?" params]
token         = [ ckbtc / icp / chat / bitcoin / ethereum ... ]
address       = STRING
params        = param [ "&" params ]
param         = [ amountparam ]
amountparam   = "amount=" *digit [ "." *digit ]
