Frequently Asked Questions

What is gwei?
Gwei is 1,000,000,000 wei (10^9 wei). It is the standard unit for expressing Ethereum gas prices. One gwei equals 0.000000001 ETH.
What is wei?
Wei is the smallest denomination of Ether — the atomic unit of ETH. 1 ETH = 10^18 wei. It's used internally by the Ethereum protocol.
Why does this use BigInt?
Ethereum amounts can be very large integers (up to 10^18 for one ETH in wei). JavaScript floating-point numbers lose precision at those scales, so exact BigInt arithmetic is used instead.
