A ticker symbol is the short code that identifies a cryptocurrency on an exchange — BTC for Bitcoin, ETH for Ethereum, SOL for Solana. It is a compact, unambiguous shorthand that replaces the full project name in quotes, charts and order screens.
Tickers are not universally standardised across crypto markets. The same symbol can in principle refer to different tokens on different exchanges, and thousands of tokens share ambiguous short codes. Context — which exchange and which contract address you are on — matters.
Confusingly similar tickers are a genuine source of error, with investors occasionally buying the wrong asset entirely. Always confirm that a ticker maps to the specific coin you intend, using the contract address on a block explorer if in doubt.
Worked example
BTC identifies Bitcoin, ETH identifies Ether — each a short stand-in for the full project name.
