Ethereum 2.0 Conversion Issue: ethers.toBigInt() is not defined
Starting with Ethereum 2.0, the ethers.toBigInt() method has been deprecated in favor of more modern and accurate methods for converting between bigints and strings. However, a bug is still being reported by users like you.
In this article, we will dive into the details of the issue and explore possible solutions to resolve it.
Issue: ethers.toBigInt() is not defined
When calling ethers.toBigInt() on a converted value from 2.0, you get the following error:
TypeError: ethers.toBigInt(...).eq is not a function
This indicates that the ethers.toBigInt() method does not have an eq method.
Reason for inactivity
In Ethereum 2.0, the ethers library API underwent significant changes to accommodate new features and improvements to the Ethereum ecosystem. In particular, the toBigInt function was replaced by the BigInt type from the bigint module.
While this change was intended to provide a more accurate and efficient way to work with bigints in JavaScript, it caused some inconvenience for users like you who are still using version 6 of the library.
**Troubleshooting: Using BigInt.toString() or BigInt.toString()
To resolve the issue, you can use one of two options:
Option 1: Use BigInt.toString()
`JavaScript
const bigIntValue = ethers.toBigInt(123);
console.log(BigInt.toString(bigIntValue));
BigInt.toString()This correctly converts a bigint to a string.
Option 2: Use
BigInt.toString()Alternatively, you can store the result of
using the same syntax as option 1:
Javascript
const bigIntValue = ethers.toBigInt(123);
console.log(BigInt.toString(bigIntValue));
ethers.toBigInt()
ConclusionThe error message indicates that
does not have aneqmethod. To resolve this issue, you can use one of the two options described above or remove the call toethers.toBigInt()and let JavaScript handle the conversion for you.By following these steps, you should be able to bypass the error and successfully compare your converted bigint using the ether library on Ethereum version 2.0.
Example Use CasesTo further clarify the point, here are some example use cases:
Javascript
// Option 1: Using BigInt.toString()
console.log(ethers.toBigInt(123).toString());
// Option 2: No need to call ethers.toBigInt() and use BigInt.toString() instead
const bigIntValue = 123n;
console.log(BigInt.toString(bigIntValue));
“
By following these simple steps, you will be able to resolve the error and successfully work with Bigint conversions in Ethereum 2.0.
