## [Chainlink](https://chain.link)

Chainlink is an oracle platform that provides market data and other services to smart contracts across many blockchains. On Stellar, [Chainlink Data Feeds](https://docs.chain.link/data-feeds/stellar) and [Chainlink Data Streams](https://docs.chain.link/data-streams/tutorials/stellar-onchain-report-verification) are live. Read the [launch announcement](https://stellar.org/blog/foundation-news/chainlink-is-now-live-on-stellar-unleashing-a-new-wave-of-defi-innovation) on the Stellar blog.

Data Feeds on Stellar use a single proxy contract that serves every feed. Instead of a per-feed contract address, a consumer selects a feed by its 32-byte `data_id`, which is the **Feed ID** listed on the [Chainlink price feed addresses page](https://docs.chain.link/data-feeds/price-feeds/addresses?network=stellar) with Stellar selected. The proxy is not SEP-40 compatible. Consumers call `latest_round(data_id, decimals)` or `get_round(data_id, round_id, decimals)`, and each round returns a `round_id`, an `answer` (`I256`), and a `timestamp`. Answers are stored at 18 decimal places. Pass `18` as `decimals` unless Chainlink has approved a reduced precision for the feed.

Data Streams uses a pull model. Applications fetch signed reports off-chain and verify them on-chain through the Chainlink Verifier contract. Using Data Streams requires an account allowlisted by Chainlink.

To integrate, see [Using Data Feeds Offchain](https://docs.chain.link/data-feeds/stellar/using-data-feeds-off-chain), [Using Data Feeds Onchain](https://docs.chain.link/data-feeds/stellar/using-data-feeds-on-chain), and [Verify Data Streams reports onchain (Stellar)](https://docs.chain.link/data-streams/tutorials/stellar-onchain-report-verification). The proxy interface is defined in the [chainlink-stellar](https://github.com/smartcontractkit/chainlink-stellar) repository.
