LINK Token Contracts | Chainlink Documentation (2024)

LINK tokens are used to pay node operators for retrieving data for smart contracts and also for deposits placed by node operators as required by contract creators. 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.

The LINK token is an ERC677 token that inherits functionality from the ERC20 token standard and allows token transfers to contain a data payload. Read more about the ERC677 transferAndCall token standard.

To use Chainlink services on a given blockchain, it is necessary to use LINK tokens. You can transfer tokens across blockchains by using Chainlink CCIP or applications such as Transporter and XSwap.

Is link an ERC20 token? ›

Please note: Chainlink (LINK) is an ERC20 Token. If you don't hold any LINK, you will not see the LINK Chainlink option under your ETH account. Since LINK is an ERC20 token, you don't need to have a separate LINK account. Instead, you can have an Ethereum (ETH) account that contains LINK.

Discover More Details ›

How does the link token work? ›

LINK is the ERC-20 token used to pay for services on the Chainlink oracle network. It essentially powers the architecture of Chainlink itself. Requesting Contract holders use LINK to pay node operators for their work providing the data needed.

What is the Chainlink reputation contract? ›

The Chainlink Reputation Contract, checks an oracle provider's track record to verify its authenticity and performance history — then evaluates and discards disreputable or unreliable nodes.

Can I unstake Chainlink? ›

If a staker completes a withdrawal of any amount of their staked LINK, their ramp-up period will reset to 0% and any Locked Rewards earned will be forfeited back to the rewards pool and become available for all stakers in the same category (i.e., a Community Staker's Forfeited Rewards can then be earned by all ...

Why not buy Chainlink? ›

The most significant risk at play with Chainlink's price and investing in the token LINK, or even making a Chainlink price prediction, is the fact that the underlying token is used to pay node operators, unlike other Cryptos that are used as a store of wealth or even as a decentralized currency.

Tell Me More ›

Why is Chainlink taking off? ›

And that's why Chainlink is so hot right now: it's a decentralized oracle network (DON), meaning it eliminates the single point of failure inherent to centralized networks and allows its customers to leverage the technology's full power in a more reliable manner.

What blockchain is Link on? ›

Chainlink is a decentralized blockchain oracle network built on Ethereum. The network is intended to be used to facilitate the transfer of tamper-proof data from off-chain sources to on-chain smart contracts.

Explore More ›

Is Chainlink proof of stake? ›

Here's how it does this: Chainlink is a proof-of-stake (PoS) blockchain, which means there's no mining or miners. Instead, node operators “stake” (i.e. deposit) LINK tokens as crypto collateral so Chainlink runs smoothly. In return, they can earn more LINK.

How many link tokens are there? ›

Currently, there are over 450,000,000 LINK Coins circulating. The maximum supply of coins is one billion.

Does Chainlink use smart contracts? ›

Chainlink is a decentralized oracle network or blockchain abstraction layer that communicates off-chain data to a blockchain. Its oracles securely enable computations on- and off-chain, supporting what it calls hybrid smart contracts and its cross-chain interoperability protocol.

Why is Chainlink so valuable? ›

But why is Chainlink so important? Chainlink is essential because it significantly enhances smart contract capabilities by allowing access to data outside the blockchain and off-chain computing while keeping blockchain technology's security and reliability assurances.

Is a link token a good investment? ›

Just like the name suggests, the Chainlink network is used to link chains — it uses a decentralized oracle network to connect external data sources to various blockchains. Beyond being an interesting project with solid real-world applications, Chainlink is also a worthwhile investment.

How important is Chainlink? ›

Today, Chainlink helps to bridge the growing gap between external data sources and public blockchains in new and exciting ways. In 2017, Chainlink hosted an ICO that was, at the time, one of the largest events to take place. The network has been in the spotlight ever since.

Does link coin have a future? ›

Coinpedia platform predicts Chainlink could reach $213.1 to $253.51 by 2030, and experts from Changelly forecast that it could reach minimum and maximum prices of $30.69 and $38.26 by the end of 2025.
