How does Nijipe handle Bitcoin address derivation?

Nijipe derives a unique native SegWit address per invoice from the merchant's XPUB or ZPUB using BIP84 derivation. Addresses are never reused. Funds flow directly to the merchant's wallet — Nijipe never takes custody of on-chain funds.

What is the fee for using Nijipe?

Nijipe charges 0% per transaction. Merchants pay a flat $15 per month for full API access. Bitcoin network fees and Lightning routing fees are passed through at cost without markup.

How do I verify a Nijipe webhook signature?

Compute HMAC-SHA256 of the raw request body string using your store's dedicated webhook secret as the key. Compare using crypto.timingSafeEqual() against the X-Nijipe-Signature header value. Never use string equality comparison for HMAC verification.

Is Nijipe custodial or non-custodial?

On-chain Bitcoin payments are fully non-custodial. Merchants provide an XPUB or ZPUB and Nijipe derives unique receiving addresses per invoice using BIP84. Funds go directly to the merchant's wallet. Lightning Network payments on the standard tier use a shared LND node managed by Nijipe.

Address Derivation

Nijipe leverages BIP84 for native SegWit address derivation. When an XPUB or ZPUB is provided, the platform derives unique bech32 (bc1q...) addresses for each invoice using the derivation path m/84'/0'/0'/0/{index}.

Security & Privacy

By utilizing extended public keys (XPUBs), Nijipe can generate an infinite number of receiving addresses without ever having access to the private keys. This ensures a non-custodial architecture where funds are settled directly to your wallet.

To preserve privacy and prevent address reuse, the derivation index is incremented atomically for each new invoice created.
