Bitcoin
BTCPeer-to-peer money
The original peer-to-peer cryptocurrency. Bitcoin combines a public ledger with a predictable issuance schedule.
Supply limit21M BTC
Under the hood +
Miners propose blocks, while full nodes independently check the rules. The 21 million limit is a protocol rule; transactions and balances are public, even though addresses are not names.
Ethereum
ETHProgrammable applications
A network for smart contracts and applications. Its native asset, ether, pays transaction fees and helps secure the network.
Core ideaSmart contracts
Under the hood +
A smart contract is code executed by the network. Validators stake ETH to help agree on its state. An application’s code and permissions matter as much as the asset used to pay its fees.
Solana
SOLApplications & payments
A programmable blockchain for applications and token transfers. SOL is used for network fees and staking.
Fee assetSOL
Under the hood +
Validators help secure the network through proof of stake. Tokens on Solana can have their own issuers and rules, while the network transaction fee is paid in SOL.
Monero
XMRPrivate digital payments
A cryptocurrency designed around transaction privacy. Privacy protections are part of ordinary transfers by default.
Design focusPrivacy by default
Under the hood +
Monero uses cryptography to conceal transaction amounts and protect sender and recipient information on its ledger. On-chain privacy does not remove every risk from a device or a network connection.
USD Coin
USDCDollar-linked transfers
A stablecoin issued by Circle, designed to track the US dollar. It is available on multiple supported blockchains.
Reference currencyUS dollar
Under the hood +
Circle reports reserves backing USDC. Its issuer, redemption conditions, and the chosen blockchain all matter. A dollar target does not guarantee the price quoted by every market.
