What is Chainlink (LINK)?

Smart contracts cannot see outside their own chain, and Chainlink is the network that fills that gap: independent node operators fetch prices and other external data, agree on an answer, and deliver it on-chain, with the same infrastructure extended into cross-chain messaging, contract automation and reserve verification. LINK is what pays those operators and what they put up as collateral, which can be cut if they report badly.

Two technical quirks matter when you hold it.

LINK on Ethereum is an ERC-677 token, an ERC-20 with an extra transferAndCall function. Contracts that accept LINK as payment usually expect that call, which is why funding an oracle subscription by plain transfer can leave the tokens sitting in the contract with nothing credited. On Ethereum it also means LINK cannot pay its own gas - that is always ETH.

On every other chain, LINK is not natively issued; it is a representation created by a bridge. On some networks more than one such version has existed side by side, with identical name and symbol but different contracts, and a protocol that accepts one may not recognise the other. Before sending LINK into any application off Ethereum, confirm which version it wants.

With LINK spread across this many chains, a wallet has to stop treating it as one number. Tangem holds a distinct balance per network and names the outgoing network on the screen you confirm before the card signs - your address is the same string on every EVM chain, so that label is the only clue about where the tokens actually go. Reading it takes a second and settles a question that address alone never answers.
