Units

Each world is comprised of 1,000,000,000,000,000,000 (1018) wei, so not even a single world can be stored numerically without exceeding the range of JavaScript numbers. Gas fees are denoted in gwei.

  • 1 world = 1018 wei
  • 1 wei = 10-18 world
  • 1 gwei = 10-9 world

For that reason, only string balance properties are available, which are balanceString, confirmedBalanceString, and spendableBalanceString.

Tokens

The Worldchain natively supports ERC20 tokens.

Stake

Staking is out of scope for these chains as they don’t have native support for them.
