What is the first block of Nibiru’s EVM?

How does Nibiru’s wei differ from Ethereum’s wei?

Because Nibiru started out as a Cosmos blockchain, the native gas token NIBI has a decimal denomination of 6. That means the smallest transferrable unit is one micro-NIBI (1 unibi, or 10^-6 NIBI).

However, on Ethereum, the smallest transferrable unit is one wei == 10^-18 ETH. To maintain compatibility with smart contracts that depend on the 18 decimals of precision, we decided to make Nibiru’s EVM recognize 10^18 wei as 1 NIBI. But since Nibiru’s smallest transferrable unit is actually 10^-6 NIBI (due to the Cosmos SDK limitation), the smallest unit transferrable on Nibiru is 10^12 wei.

For developers, that means that precision digits smaller than 10^12 wei will be truncated. For example, 1,999,999,999,999 wei will be truncated as 1,000,000,000,000 wei. If you’re doing gas estimations, it would be prudent to add 10^12 wei to the estimated gas amount to ensure that you’re not affected by this truncation issue.

It also means that transfers are truncated to 10^12 wei. In practice, that means amounts smaller than 1 micro-NIBI are truncated, but that should have minimal monetary impact, as we’re talking about tiny fractions of a cent.

What is the source of RANDDAO for blocks?

The randomness comes from the block time and the last commit hash.

Is NIBI also an ERC-20 token?

NIBI itself is not an ERC-20, but there is a WNIBI ERC-20 contract, similar to how ETH has WETH on Ethereum.

The contract address is 0x7D4B7B8CA7E1a24928Bb96D59249c7a5bd1DfBe6

If I get USDC in WASM via IBC and added some more in EVM side via a bridge will I see 2 different token balances or just one?

Two different token balances

Do EVM and wasm txs occur in parallel?

No, serially

Which consumes more gas? EVM or wasm?

It depends on the smart contract
