ecc.isPoint is not a function

[indexxai]

Hi All,

`const ecc = require('tiny-secp256k1');
console.log(ecc.isPoint)
const { BIP32Factory } = require('bip32');
// You must wrap a tiny-secp256k1 compatible implementation
const bip32 = BIP32Factory(ecc);
const bip39 = require('bip39');
const bitcoin = require('bitcoinjs-lib');

export function generateBitcoinTestAddress(mnemonic) {
//const bip32 = BIP32Factory.default(ecc);
const seed = bip39.mnemonicToSeedSync(mnemonic);
const root = bip32.fromSeed(seed);

const path = "m/49'/1'/0'/0/0";
const child = root.derivePath(path);

const { address } = bitcoin.payments.p2sh({
redeem: bitcoin.payments.p2wpkh({
pubkey: child.publicKey,
network: bitcoin.networks.testnet,
}),
network: bitcoin.networks.testnet,
});
console.log(address, "address");
}

export function generateBitcoinMainAddress(mnemonic) {
//const bip32 = BIP32Factory.default(ecc);
const seed = bip39.mnemonicToSeedSync(mnemonic);
const root = bip32.fromSeed(seed);

const path = "m/49'/0'/0'/0";
const child = root.derivePath(path);

const { address } = bitcoin.payments.p2sh({
redeem: bitcoin.payments.p2wpkh({
pubkey: child.publicKey,
network: bitcoin.networks.bitcoin,
}),
network: bitcoin.networks.bitcoin,
});
} `

I could not able to bip32 throws following error

I'm having the same issue

\node_modules\.pnpm\bip32@4.0.0\node_modules\bip32\src\testecc.js:6 assert(ecc.isPoint(h('0279be667ef9dcbbac55a06295ce870b07029bfcdb2dce28d959f2815b16f81798'))); ^ TypeError: Cannot read properties of undefined (reading 'isPoint')

EDIT: I fixed using import * as ecc from 'tiny-secp256k1';

Hey everyone, I ran into this issue while working with Node.js, and here’s what I found:

Cause
tiny-secp256k1 is an ES module, and when using it in a CommonJS (require) project, it might not be properly wrapped.

Solution:
Instead of:
const ecc = require('tiny-secp256k1');

Try using dynamic import:

import * as ecc from 'tiny-secp256k1';
Or, if your project uses CommonJS, modify how you require it:

const ecc = require('tiny-secp256k1');
const { default: eccDefault } = require('tiny-secp256k1');
const finalEcc = ecc.default || eccDefault || ecc;

Then use:
const bip32 = BIP32Factory(finalEcc);
This ensures that ecc is correctly wrapped for BIP32Factory.

Note:-
If using ESM (import), updating to:
import * as ecc from 'tiny-secp256k1';
should work.
If using Node.js v14+, ensure your package.json has "type": "module" when using import.

Let me know if this works.

Would you like me to submit a PR with this fix? Let me know if any further improvements are needed!
