Metamask: Ether.js BigNumber overflow when I use a contract with wei

Metamask Ether.Js Bigmumber Overflowing: Wizard problem -solving for smart contracts

As a developer working with Defi applications, you have probably encountered problems related to the conversions of a large number of AWEI. In this article, we will dive into the problem of Bigmber overflow when using metamask on Ethereum, namely with respect to ether.

problem

When the user is trying to enter in a wallet above 999 over 999, he triggers a Bigmbber overflow error. The reason is that Bigmber.JS expects numbers to a certain extent (usually between -2^53 and 2^53) until it causes a slump. When the input exceeds this range, the result is wrapped around, leading to incorrect conversions.

problem with ether.Js Bigmberm

The ether.JS provides implementation of Bigmberm, which allows arithmetics of arbitration accuracy. However, when using metamascus for Ethereum, the Bigmbber library is not designed to effectively handle a large number. This can lead to performance problems and ultimately to an error of overflow.

Solution: Use a decimal library or other Bigmberm library

In order to avoid the Bigmberm overflow problem, it is recommended to use a more appropriate library to process numbers in your intelligent contract. Two popular alternatives are:

* decimal.js : JavaScript library, which provides support for decimal arithmetic up to 1024 digits. In your code, you can easily replace Bigmumber.JS for the decimal page.

* BNP.JS : Another popular implementation of Bigmumber specifically designed for Ethereum.

Here is an example of how you could edit your contract to use bnp.JS:

`Javascript

Import {bn} z ‘@bnpjs/bn-polyfill’;

// Define variables

Const Sum = New BN (‘0x123456789012345678901234567890’);

// make a conversion and save the result

New BNB (). GetDecimalamount (amount);

`

Proven procedures

• When working with a large number, consider using a library that provides optimized Bigmber implementation, such as a decimal value.

• Always verify user input to avoid unexpected errors.

• Keep the logic of your contract separately from the library used to process numbers. If necessary, this will facilitate switching between libraries.

Conclusion

By understanding the problem of Bigmber overflow when using metamascaster on Ethereum, you can take steps to avoid this problem and ensure the success of your intelligent contracts. By examining alternative libraries such as decimal.js or bnp.js, you will be able to write a more efficient and more reliable code that easily processes large numbers.
