DesmJS is a library containing a set of various packages that make it easy to develop an application on top of the Desmos blockchain.
DesmJS consists of multiple smaller npm packages each one with a specific functionality.
| Package | Description | Version |
|---|---|---|
@desmoslabs/desmjs |
Contains the client to interact with the Desmos chain |  |
@desmoslabs/desmjs-types |
Contains the Desmos Protobuf definitions |  |
@desmoslabs/desmjs-keplr |
Contains the Keplr signer implementation |  |
@desmoslabs/desmjs-walletconnect-v2 |
Contains the WalletConnect v2 signer implementation |  |
@desmoslabs/desmjs-web3auth-mobile |
Contains the Web3Auth Web signer implementation for React Native projects |  |
@desmoslabs/desmjs-web3auth-web |
Contains the Web3Auth Web signer implementation |  |
If you encounter address generation issues while using the @desmoslabs/desmjs or @desmoslabs/desmjs-web3auth-mobile
package, particularly on Android devices, you may be experiencing a problem related to the @noble/hashes library.
The root cause lies in the absence of the setBigUint64 method in the DataView object.
This method is crucial for proper SHA2 calculations, but it may not be available on certain Android devices,
leading to incorrect address generation when importing an account using mnemonic or private key.
By polyfilling the setBigUint64 method, you can overcome this issue without the need for multiple patches.
To implement the polyfill you can copy the following js code into your shim.js file.
if (global.DataView.prototype.setBigUint64 === undefined) {
global.DataView.prototype.setBigUint64 = function (byteOffset, value, isLE) {
const _32n = BigInt(32);
const _u32_max = BigInt(0xffffffff);
const wh = Number(value.shiftRight(_32n) & _u32_max);
const wl = Number(value & _u32_max);
const h = isLE ? 4 : 0;
const l = isLE ? 0 : 4;
this.setUint32(byteOffset + h, wh, isLE);
this.setUint32(byteOffset + l, wl, isLE);
};
}
