## Introduction

The Ethereum Attestation Service is a free and open protocol for on-chain attestations on EVM compatible blockchains. It is a generalized service that allows anyone to register a schema for their particular use case, and then make attestations following their schema.

Schemas can be registered using the `SchemaRegistry.sol` contract, and attestations are made using the `EAS.sol` contract.

In addition, we provide a resolver contract for advanced use cases, such as on-chain verification of attestation data, and also attaching payments to attestations (which makes a new suite of powerful web3 applications possible).

We also provide an SDK for developers.

On-chain attestations will enable a powerful new range of web3 applications, including:

* Identity
* Trust Scores
* Goodness Scores
* Credit Scores
* Clout
* Land Registries
* Social Networks
* Portable Trust Layers
* Retroactive Public Goods Funding
* KYC Services
* Uncollateralized Lending / Borrowing
* Voting
* Oracles (who can be atomically paid for making attestations inside the protocol)
* Likes/Dislikes
* Content Filtering
* And many more!

## Deployments

Please note that you can also import and use the addresses directly in your code using the `@ethereum-attestation-service/eas-contracts/deployments` deployment artifacts corresponding to your desired network.
