v0.5.0-testnet-holesky

What's Changed

Added 🎉

• Added all features of the eigensdk crate to its "full" feature #370

  • This includes: "types", "utils", "metrics-collectors-economic", and "metrics-collectors-rpc-calls" features.

• Bump alloy to 0.12 in #381.

• Added register_for_operator_sets_with_churn method to elcontracts/writer in #382.

    let el_chain_writer_2 =
        new_test_writer(http_endpoint.clone(), SECOND_PRIVATE_KEY.to_string()).await;
  
    let bls_key_pair = BlsKeyPair::new(OPERATOR_BLS_KEY_2.to_string()).unwrap();
    let churn_private_key = FIRST_PRIVATE_KEY.to_string();
    let churn_sig_salt = FixedBytes::from([0x05; 32]);
    let churn_sig_expiry = U256::MAX;
    
    let tx_hash = el_chain_writer_2
        .register_for_operator_sets_with_churn(
            SECOND_ADDRESS,         // Operator address to register
            bls_key_pair,           // Operator's BLS key pair
            avs_address,            // AVS address
            vec![operator_set_id],  // Operator set ID
            "socket".to_string(),   // Socket address
            Bytes::from([0]),       // Quorum numbers
            vec![FIRST_ADDRESS],    // Operators to kick if quorum is full
            churn_private_key,      // Churn approver's private key
            churn_sig_salt,         // Churn signature salt
            churn_sig_expiry,       // Churn signature expiry
        )
        .await
        .unwrap();

Breaking Changes 🛠

• Renamed set_account_identifier to set_avs #365

  • The underlying call was renamed in the v1.1.1 eigenlayer-middleware release.

• Changed the signature of build_avs_registry_chain_writer in #384.

  • The operator_state_retriever_addr parameter was replaced by service_manager_addr.
  • This change was made because later middleware versions do not include ServiceManager.

  // Before
  pub async fn build_avs_registry_chain_writer(
      logger: SharedLogger,
      provider: String,
      signer: String,
      registry_coordinator_addr: Address,
      _operator_state_retriever_addr: Address,
  ) -> Result<Self, AvsRegistryError> {}
  
  // After
  pub async fn build_avs_registry_chain_writer(
      logger: SharedLogger,
      provider: String,
      signer: String,
      registry_coordinator_addr: Address,
      service_manager_addr: Address,
  ) -> Result<Self, AvsRegistryError> {}

• Bump middleware to v1.4.0-testnet-holesky in [#396] , [#365], [#395] and [#388].

  • Added method is_operator_slashable.

  let chain_reader = build_el_chain_reader(http_endpoint.clone()).await;

  let operator_set = OperatorSet {
      id: 1,
      avs: Address::ZERO,
  };

  let is_slashable = chain_reader
      .is_operator_slashable(OPERATOR_ADDRESS, operator_set)
      .await
      .unwrap();
  assert!(!is_slashable);

• Added method get_allocated_stake.

  let chain_reader = build_el_chain_reader(http_endpoint.clone()).await;

  let operator_set = OperatorSet {
      id: 1,
      avs: Address::ZERO,
  };
  let operators = vec![OPERATOR_ADDRESS];
  let strategies = vec![get_erc20_mock_strategy(http_endpoint.to_string()).await];
  let slashable_stake = chain_reader
      .get_allocated_stake(operator_set, operators, strategies)
      .await
      .unwrap();

• Added method get_encumbered_magnitude.

  let chain_reader = build_el_chain_reader(http_endpoint.clone()).await;

  let magnitude = chain_reader
      .get_encumbered_magnitude(
          OPERATOR_ADDRESS,
          get_erc20_mock_strategy(http_endpoint.to_string()).await,
      )
      .await
      .unwrap();

• Updated error types in BlsAggregationServiceError for channel failures in the BLS Aggregator Service (#392).
  • Before: A generic ChannelError was used for both sender and receiver channel failures.
  • After: Distinct errors are now provided:
    • SenderError is returned when the sender channel fails to send a message to the service.
    • ReceiverError is returned when the receiver channel fails to receive a message from the service.

Removed 🗑

• Removed unused empty structs from the library in #371
  • eigen_client_eth::client::Client
  • eigen_services_operatorsinfo::OperatorPubKeysService
• Removed the AvsRegistryChainReader::is_operator_set_quorum method #365
  • This function was removed in the v1.1.1 eigenlayer-middleware release.

Documentation 📚

• Reflect 2 bindings(rewardsv2 and slashing) in readme in #383.
