A BIP47 compatible library written in TypeScript with transpiled JavaScript committed to git.

const paymentAddress = aliceBip47.getPaymentAddress(bobPublicBip47.getPaymentCodeNode(), 2);
// bob private bip47
const bobPrivateBip47 = BIP47Factory(ecc).fromBip39Seed(bobSeedPhrase);
// third alice to bob wallet (bip32)
const wallet = bobPrivateBip47.getPaymentWallet(aliceBip47.getPaymentCodeNode(), 2);
// third wallet private key
const privateKey = wallet.privateKey?.toString('hex');
// examples of how to generate blinded payment code
// and retrieving payment code from notification transaction
// can be found in tests
see tests for more examples.
- generate payment code from seed phrase or seed hex
- generate payment addresses
- generate notification address from payment code
- generate receiving addresses/privateKeys for a payment code
- generate blinded payment code for notification transaction
- retrieve payment code from raw notification transaction
