Stake CUDOS tokens to earn rewards as either a Validator or Delegator. Validators must be whitelisted by sharing their MetaMask wallet address and can set their own fees. Delegators can stake through the wallet.cudos.org portal to earn estimated 30% APY rewards distributed after each block. Staking requires Ethereum for gas fees but allows easy migration of tokens to the native Cudos chain when launched. The CUDOS token serves utility purposes like network governance, receiving workloads as a stake, and medium of exchange.
