# LINK Token Contracts Source: https://docs.chain.link/resources/link-token-contracts *** > **NOTE: Talk to an expert** > > Contact us to talk to an expert about the networks that > support the LINK token. The LINK token is the native digital asset of the Chainlink Network. It serves as the standard unit of payment for Chainlink services and as a core component of the network’s cryptoeconomic security through staking. As more developers, enterprises, and financial institutions use Chainlink to build institutional-grade smart contract applications, LINK provides a shared economic framework that helps strengthen the network’s security and service quality. ### Payment for oracle services The LINK token is used by developers and organizations to pay fees to access Chainlink services, similar to how the native coins of blockchain networks are used to pay for transaction gas fees (e.g., ETH on Ethereum). To support network reliability, LINK is the standard unit of compensation to network service providers, such as node operators, for successfully facilitating Chainlink services. This helps align the incentives of node operators with the long-term health and proper functioning of the network. ### Payment Abstraction To reduce payment friction and accelerate adoption, [Payment Abstraction](https://blog.chain.link/payment-abstraction-svr-fee-conversion/) allows users to pay for Chainlink services using their preferred form of payment, including onchain tokens and offchain fiat payments. These payments are then programmatically converted into LINK tokens using decentralized exchange infrastructure. ### Chainlink Reserve Payment Abstraction is used to help build the [Chainlink Reserve](https://blog.chain.link/chainlink-reserve-strategic-link-reserve/), a strategic onchain reserve of LINK tokens designed to support the network’s long-term growth and sustainability. The Chainlink Reserve is funded by offchain revenue from enterprise adoption of the Chainlink standard, as well as onchain revenue from service usage. ### Network security and rewards [Chainlink Staking](https://chain.link/economics/staking) uses the LINK token to support the network’s cryptoeconomic security. Node operators and community members stake LINK, which can be subject to slashing if predefined performance requirements are not met. In exchange for helping secure the network, stakers receive staking rewards. ### Token standard and cross-chain transfers The LINK token is an [ERC-677 token](https://github.com/ethereum/EIPs/issues/677) that inherits functionality from the ERC-20 token standard and allows token transfers to contain a data payload. The smallest denomination of LINK is called a Juel, and 1,000,000,000,000,000,000 (1e18) Juels are equal to 1 LINK. This is similar to Wei, which is the [smallest denomination of ETH](https://ethereum.org/en/developers/docs/intro-to-ether/#denominations). The LINK token was originally issued on the Ethereum blockchain and can be securely transferred cross-chain by using [Chainlink CCIP](https://docs.chain.link/ccip/tutorials/evm/transfer-tokens-from-contract) and CCIP-powered applications such as [Transporter](https://app.transporter.io/?tab=token\&token=LINK). > **NOTE: Interfaces and Applications** > > Chainlink CCIP is a messaging protocol.
