What Chainlink is used for

Chainlink provides infrastructure that allows smart contracts to interact with external data. This is done through oracles, which provide the data feeds necessary for DeFi applications to function.

The platform offers several specific tools:

• CCIP, Data Streams, Data Feeds, and Proof of Reserve.
• Integration with the Circle-backed Arc program to help developers build on stablecoin-native Layer-1s.
• Support for real-world asset (RWA) use cases within stablecoin ecosystems.

The LINK token is the utility asset used to pay for these services.

Wallet, network, and custody checks

LINK exists on multiple networks. You must verify the contract address and the network before making any transfers to avoid loss of funds.

Common mistakes before buying LINK

Users often make a few specific errors when acquiring LINK:

• Using a lookalike contract address or selecting the wrong network.
• Assuming that every exchange supports deposits and withdrawals for every network.
• Ignoring KYC requirements or country-specific restrictions before opening an account.
• Relying on live price or volume snapshots as permanent data.

Route, liquidity, and availability caveats

Deposit and withdrawal support is not verified for the listed routes unless the source explicitly provides that data.

KYC requirements and account features vary by platform. For example, Bybit and MEXC have specific lists of banned countries. You should check the current terms of the exchange for your specific region before depositing funds.

Sources and methodology

The routes in this guide come only from verified market-pair rows in our database. Web research and news from sources like BSC News are used for background and risk context. Information from CoinMarketCap pages is treated as low-confidence context. Live market values are omitted because they change too frequently to remain accurate in a static guide.
