Model:

• New Transaction7702
• New Transaction7702Encoder (RLP encoding / decoding)
• TransactionFactory update to create 7702 transactions directly, from a generic input or rlp
• New transaction Type (0x04)
• Authorisation7702 and Authorisation7702Signed both supported by Encoders, First one used to sign authorisations
  RPC:
• New Authorisation RPC object and Model mappers
• Changes to TransactionInput and Transaction to include Authorisations
• Changes to TransactionManagerBase to include identification of EIP7022 transaction types if included the authorisation list, also include common methods to Add authorisations or remove authorisations to the next request, default gas calculation optimised to add extra 2500 per authorisation if either present on the transaction input or in the next requests to be appended to the transaction

Signer:
New: Transaction7702Signer similar generic same as 1059

• Authorisation7702Signer signer to authorise items requests before including them into the 7022 transaction.
• EthECKeyBuilderFromSignedAuthorisation to recover the the signer from Authorisation7702Signed authorisation
• DecodeRLPToAuthorisation7702 to validate the rlp that is being signed by the user... (what am I authorising)

Updates:

• EthECKeyBuilderFromSignedTransaction update to recover from Transaction7702 transaction
• EthExternalSignerBase generic external signer support of 7702.
• Aws, Azure enable generic signing of 7702
• Ledger, Trezor, marked as unsupported

Accounts:

• AccountSignerTransactionManager at the time of nonce allocation, does the signing of all the authorisations to ensure correct nonces in sequencing order based on the nonce manager, authorisations are merged from the request queue onto the transaction input.
• OfflineTransactionSigner update.
• ExternalAccount signing partial support whilst it can sign the 7702 this needs to be implemented to SignAuthorisationAsync and nonce flow

Contracts

• Added AuthorisationList to the common contract object and encoding services

Tests

• Signing Integration tests, included smart contracts examples BatchCall as a contract to be used as 7702 (enabling multiple calls) and delegation.

Services

• 7022SponsorAuthorisationService (Sign authorisations for multiple external accounts),
• AuthorisationGasCalculator (core gas calculator),
• AuthorisationSigner batch key signing support
• Tests to batch creation / authorisation

• MulticallInputOuputRpcBatchItem and CreateMulticallInputOutputRpcBatchItems
  To be able to send batches of rpc calls and decode them the MultiQueryBatchRpcHandler includes CreateMulticallInputOutputRpcBatchItems. This method using the multicalls creates a set of MulticallInputOutputRpcBatchItems that contains both the multicallinputouput for decoding the call data and the newly created based on the multicallinputoutput rpcRequestResponseBatchItem.
  MulticallInputOuputRpcBatchItem implements the interface of IRpcRequestResponseBatchItem by wrapping the rpcRequestResponseBatchItem so it can be used as any other normal batch request

• Allowing partial success in batch requests. by @dlebee in #1070

Commits: 633474d, 11c5945

New shuffler and bytes shuffler specialised to help when creating random sets of bytes / numbers (or anything), based on the card shuffling strategy, so no consecutive values can be guessed based on a generic set or rng if guessed.

Commits: cfe1ff4

• The EVM simulator includes a Gas counter.
• New Op codes supported: BASEFEE- BLOBHASH - BLOBBASEFE- TLOAD - TSTORE
  Commits: ee6b4d7

• Nethereum.Geth use StateChange from the core RPC project
  Commit: ec4c916

• Change of package and version to BouncyCastle.Cryptography 2.5.1, but open to any version up to 3.0.0, targeting frameworks net90, net80, net60 and net472, leaving portable to other versions (previous) due to compatibility issues.
• fix issue in ToDER() method, thanks to the pull request by @tmm360 in #1071

.NET Native (now part of Native AOT in .NET) compiles .NET applications ahead-of-time into platform-specific machine code, eliminating the need for a JIT compiler and reducing startup time, memory usage, and deployment size. To enable this and continue to be backwards compatible requires many changes (at core), mostly caused by JSON encoding and decoding.

• Nethereum.JsonRpc.SystemTextJsonRpcClient is a brand new project and AOT-friendly JSON-RPC client for Ethereum, using System.Text.Json.

This provides new RPC Client component and Simple RPC Client component, including also Nethereum RPC Context for generated serialisation of RPC types to provide the RPC transport with System.Text.Json instead of Newtonsoft making it suitable for AOT Native builds using .net9.

Commits: e99d174

• Update all the Nethereum.RPC DTOs, Nethereum.JsonRpc.RpcClient Messages and Nethereum.Hex HexTypes to dual support Newtonsoft.Json and System.Text.Json

   [JsonProperty(PropertyName = "decimals")]
#if NET6_0_OR_GREATER
[System.Text.Json.Serialization.JsonPropertyName("decimals")]
#endif
        public uint Decimals { get; set; }

• Transaction Receipt does not use JArray that couples it to Newtonsoft, it uses now the typed version, FilterLog, and to avoid migration issues all the extensions from receipt has been upgraded, and in scenarios the type conversion remains the same, but just returns the same object.

• All Clients now include a DecodeMethod, so any response message can be combined with the client deserialiser and settings (ie System.Text.Json specific).

• New ContractABI deserialiser ABIJsonDeserialiserSTJ to support System.Text.Json, this is an optin deserialiser, enabling to interact with smart contracts using abi strings in Native mode. Note: To workaround the fact that newtonsoft is more flexible and allows for single quotes when using Json and backwards compatibility, the deserialiser if it finds single quotes it replaces them with double quotes.

To enable it use:

AbiDeserializationSettings.UseSystemTextJson = true;

Commits: 8466e44, 5eccd83, 2b0407d

• Nethereum.ABI.SourceGenerators, (WIP) to avoid ABI decoding using the attributes and reflection when using typed FunctionMessages, Events etc. Nethereum.ABI.SourceGenerators experimental project generates the code to convert set and get the values directly when encoding and decoding at compilation time. This works very well native mode as the code is normally stripped from this scenarios. The current early implementation works on Functions and Structs, but further refining is required to allow for anonymous methods, implementation of other types and most importantly integrate it an option within the deserialising workflow.

• .NET Native example and test project
  The dotnet native example, provides many common scenarios and tests to validate the native support of Nethereum.
  Source: https://github.com/Nethereum/Nethereum/blob/master/consoletests/Nethereum.AOTSigningTest/Program.cs

A simple example of usage:

Include the namespace for the SystemTextJsonRpcClient.

using Nethereum.JsonRpc.SystemTextJsonRpcClient;

Using the RpcClient from SystemTextJsonRpcClient, and work as usual.

var localClient = new RpcClient("http://localhost:8545");
            var account = new Nethereum.Web3.Accounts.Account("0xb5b1870957d373ef0eeffecc6e4812c0fd08f554b37b233526acc331bf1544f7");
            var web3Local = new Web3.Web3(account, localClient);

            var localBalance = await web3Local
                .Eth
                .GetBalance.SendRequestAsync("0x12890d2cce102216644c59daE5baed380d84830c");

            var ethSenderService = web3Local.Eth.GetEtherTransferService();
            var transactionHash = await ethSenderService.TransferEtherAsync("0x12890d2cce102216644c59daE5baed380d84830c", 0.01m);

Note...

• New project, to be used as the basis for integrating with Blazor.
• EIP6963 support, enabling multi wallet browser extension support, like Metamask, Coinbase, Brave, Rabby etc Example of Blazor Project
• EthereumAuthenticationProvider, common class to provide authentication support, this should work if you use EIP963, Metamask standalone or Reown
• SiweAuthenticationServerStateProvider, common class to provide further authentications support if using SIWE, so whilst a user might be connected, it can be authenticated in certain areas of the application.
• LocalStorageAccessTokenService and LocalStorageHelper, generic helpers to manage the SIWE access tokens on generic LocalStorage.

Commits: b534f8f

• Unity support for EIP6963, including custom WeglHostProvider, Interop, etc.
• Full example in the Unity Template https://github.com/Nethereum/Unity3dSampleTemplate/

Rpc Service and requests to integrate with 4337 Account Abstraction

Commits: 7116733

• Add TryParse method to BigDecimal struct by @AnzeS in #1066
• Support NUGET_PACKAGES environment variable in Nethereum.Autogen.ContractApi by @zakhard90 in #1067

Full Changelog: 4.28.0...4.29.0

• Services now inherit from a base class with the core implementation, all methods are virtual, allowing to be overriden on the main class to add custom logic like validation.
• Mud Table Service is extended to include Set and Get methods using parameters, so now Keys Values are needed.
• Mud Table, includes accessors for both Keys and Value properties at top level, this way it can be easily accessed the data, but also in future
  use these properties as entities to get the data from a different storage or Api.

Full Changelog: 4.27.1...4.28.0

Patch to rollback the Bouncy Castle upgrade (Reported Issues)

Full Changelog: 4.27.0...4.27.1

The Mud Postgres Normaliser is a service that processes data from the StoredRecords table, which is populated by Store event logs, and normalizes it in PostgreSQL.

Key Features:

Table Creation:
For each record, the service ensures that the corresponding table based on the tableId is created. If the table doesn’t exist, it is created using schema information retrieved from the blockchain, including appropriate column types.
Data Decoding and Persistence:

The service decodes and inserts or updates the blockchain event data into the PostgreSQL database.

Singleton Tables:
Singleton tables are created with a single key of 1, simplifying their structure.

Progress Tracking:
A Progress table tracks the last processed blockNumber and rowId, allowing the service to pick up from where it left off and process data in batches.

Configurable Pagination:
The service supports configurable batch sizes, making it flexible for different use cases.

Example

public class Program
{
    public static async Task Main(string[] args)
    {
        // Set up the necessary services
        var connection = new NpgsqlConnection("Host=myserver;Username=mylogin;Password=mypass;Database=mydatabase");
        var loggerFactory = LoggerFactory.Create(builder => builder.AddConsole());
        var logger = loggerFactory.CreateLogger<MudPostgresNormaliserProcessingService>();

        // Create the repository (assuming it's already implemented and registered)
        var storeRecordsTableRepository = new MudPostgresStoreRecordsTableRepository(connection, logger);

        // Create an instance of the processing service
        var processingService = new MudPostgresNormaliserProcessingService(
            storeRecordsTableRepository,
            connection,
            logger
        )
        {
            RpcUrl = "https://localhost:8545",
            Address = "0xYourContractAddress",
            PageSize = 1000 // Optional: configure the number of records processed per batch
        };

        // Execute the normalisation process
        var cancellationToken = new CancellationTokenSource().Token;
        await processingService.ExecuteAsync(cancellationToken);
    }
}

Unity release in openupm.com https://github.com/Nethereum/Nethereum.Unity

This release introduces a IRestHttpHelper interface and a simple implementation of a REST API client for use across both .NET and Unity Nethereum projects. Key features include:

• Cross-Platform Support: The utility works in both .NET and Unity, ensuring flexibility across different platforms.
• Dynamic JSON Deserialization:
  • Utilizes System.Text.Json (STJ) for .NET 8 and newer versions.
  • Falls back to Newtonsoft.Json for Unity and older .NET versions.
• New Dependency: A new project, Nethereum.Util.Rest, has been added to handle REST client operations for DataServices and Contracts

Commits 0b4d51b

Nethereum.DataServices and Nethereum.Contracts are upgraded to use the new RestHttpHelper by default or any other implementation that implements the interface.

Fixes to Etherscan are also included.

The TablePredicateBuilder introduces a fluent API to build predicates for querying Mud storage tables that have been synchronized to an external repository (such as a PostgreSQL database). It allows developers to construct complex queries with minimal effort using chainable methods.

• Fluent API for Predicate Construction:

  • Easily create complex queries using chainable .AndEqual(), .OrEqual(), .AndNotEqual(), and other methods.
  • Supports flexible predicate building that can target specific table fields or conditions.

• Reusable across Storage Types:

  • Predicates are built on a custom set of objects, enabling them to be reused for different storage backends (e.g., PostgreSQL, SQLite).

• REST API Integration:

  • Predicates can be serialized into JSON for making REST API calls. The server can then deserialize the predicate and query the internal database storage using the same predicate structure.

var predicateBuilder = new TablePredicateBuilder<ItemTableRecord, ItemTableRecord.ItemKey, ItemTableRecord.ItemValue>("0xABC123");

var predicate = predicateBuilder
                .AndEqual(x => x.Id, 1)         // AND key0 = '0x1'
                .AndEqual(x => x.Id, 2)         // AND key0 = '0x2'
                .OrEqual(x => x.Id, 3)          // OR key0 = '0x3'
                .AndNotEqual(x => x.Id, 4)      // AND key0 != '0x4'
                .Expand();                      // Finalize the predicate

The TablePredicateBuilder simplifies querying complex storage structures and provides flexibility for different storage systems, allowing predicates to be reused and transported as needed for various scenarios such as querying a database or sending queries via REST APIs.

The Mud.Repositories.EntityFramework project offers a foundational framework to integrate with a Mud repository using Entity Framework (EF). It includes various utilities and features to support efficient querying and storage of blockchain data.

• Custom Predicate Builder:

  • Provides a predicate builder that creates SQL queries using key hex values. The queries are compiled into a SqlPredicateResult, which includes the SQL statement and arguments to safely prevent SQL injection.

• MudEFTableRepository:

  • A MudTableRepository using keys as hex and EF supporting any context that implements IMudStoreRecordsDbSets, which includes the StoreRecords and BlockProgress entities.

• BlockProgressRepository:

  • Custom implementation of the BlockProgresRepository for EF Mud

Commits dc4be4c

Provides an extended Entity Framework (EF) repository implementation for PostgreSQL.
Key features include:

• Log Processing Service: Synchronizes and processes blockchain logs into a PostgreSQL database.
• Custom DbContext and TableRepository: A custom DbContext and TableRepository are included to manage all fields stored as bytea (PostgreSQL binary format).
• PredicateBuilder: Enables dynamic querying by constructing predicates that can be used to efficiently filter data within the repository.

https://github.com/Nethereum/Nethereum/tree/master/consoletests/NethereumMudStoreRestApiClient
https://github.com/Nethereum/Nethereum/tree/master/consoletests/NethereumMudStoredRecordsRestApi

End-to-end examples for processing and querying data from blockchain store records using a PostgreSQL database. The solution includes:

Log Processing: Blockchain store records are processed and stored in a PostgreSQL database using the LogProcessor. The solution leverages Entity Framework (EF) migrations for database schema management.

REST API Integration: A flexible REST API is provided to query the stored records. The API receives requests containing predicates (in JSON format), which are converted into queries for PostgreSQL using the table repository.

Data Transformation: The queried results are transformed into Data Transfer Objects (DTOs) and further converted into table format, which is then outputted to the console.

Full Changelog: 4.21.4...4.25.0

The Contract Handler can now be overridden and changed on ContractServices, this allows for specialisation of ContractHandlers as the one used in Mud to to create a CallFrom Message when delegating a call from the given signer.

This means that Nethereum now can have 2 levels of interception, one at the rpc level, for example when using Metamask, WalletConnect etc to redirect messages to another provider, and this one at ContractHandler level when we want to sign as usual but embed the contract call into another function message.

Code generator updated (JavaScript) to support multiple configurations, this allow you to define multiple code generation settings for your smart contracts, enabling the generation of client-side code for various platforms (e.g., C#, Unity) based on Solidity ABI files.

Example of usage in vscode solidity https://github.com/juanfranblanco/vscode-solidity?tab=readme-ov-file#code-generation-with-nethereum-genmultisettings

An example of the file is:

• Fix to make AWSKeyManagementExternalSigner signed messages compatible with EIP-2 by @hasandogu in #1036
• Request batching for EthSendRawTransaction by @teledu in #1032
• Mud adding multiquery rpc support to retrieve multiple records of a table, other extra functionality on table services to simplify querying, set and delete records.
