EAS-RS

Rust utilities for the ethereum attestation service.

Repository Structure

• eas-contracts: Foundry generated bindings for the current version of the EAS contracts.
• src: EAS-RS library.

How To Use

Add this to your crate dependencies:

eas-rs = { git = "https://github.com/brech1/eas-rs" }

Then you can import:

use eas::{
    eas::*,
    eas_contracts::{
        eas::AttestedFilter,
        value_resolver::{Attestation, AttestationRequest, AttestationRequestData},
    },
    schema_registry::SchemaRegistryContract,
};

You should then instantiate a local signer with a wallet:

let wallet = MnemonicBuilder::<English>::default()
    .phrase(mnemonic)
    .build();

let signer = SignerMiddleware::new(provider, wallet.with_chain_id(CHAIN_ID));

You can then attest:

let eas = Eas::new(
    signer.clone(),
    Some(Address::from_str(EAS_CONTRACT_ADDRESS).unwrap()),
);

let att_data: Bytes = Bytes::from(data_bytes);

let att_object = AttestationRequestData {
    recipient: Address::zero(),
    expiration_time: 0,
    revocable: false,
    ref_uid: [0u8; 32],
    data: att_data,
    value: U256::zero(),
};

let att = AttestationRequest {
    schema: SCHEMA_ID,
    data: att_object,
};

eas.attest(att).await.unwrap();

Keep in mind the above snippets are just illustrative, for a full implementation you should check out this example project which includes:

• Deploying on a local testnet.
• Submitting schema.
• Attesting.
• Fetching attestations with filter.
