What to know about Ethereum and Cardano

Ethereum (ETH)

Ethereum is a programmable blockchain proposed by Vitalik Buterin and launched in 2015. Its native coin, ETH, pays for computation on the network. Thousands of tokens, stablecoins, decentralized exchanges, lending protocols and NFT collections run on Ethereum.

Sending and receiving ETH

Ethereum addresses start with 0x and are the same format on BNB Smart Chain, Arbitrum, Optimism and Polygon — so always check which network the recipient expects. The fee (gas) is paid in ETH and depends on network load; a transfer is usually confirmed within a few minutes.

Cardano (ADA)

Cardano (ADA) is a Proof of Stake blockchain launched in 2017 and led by Charles Hoskinson, one of the co-founders of Ethereum. The project is known for its research-driven, peer-reviewed approach to development.

What Cardano is used for

ADA pays fees, is staked to secure the network and is used in Cardano-based DeFi and NFT applications.

Optimism network

Optimism is an Ethereum layer-2 network. Addresses use the Ethereum format and fees are paid in ETH at a fraction of mainnet cost.
