Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses a reported issue with WalletConnect's solana_signAllTransactions functionality by integrating the necessary handling for multi-transaction signing within the application's WalletConnect service. It also updates a core dependency to ensure compatibility and leverage the latest features, enhancing the overall stability and capability of Solana transaction processing via WalletConnect.

Highlights

• WalletConnect Solana Multi-Transaction Signing: Added support for the solana_signAllTransactions action within the WalletConnectorService, allowing the application to handle requests to sign multiple Solana transactions simultaneously.
• Core Submodule Update: The core submodule has been updated to a newer commit (0d02ab1a24cacb67dfef05abfbf17430180ec98b), incorporating the latest changes from the dependency.

Code Review

This pull request introduces a new signAllTransactions case within the WalletConnectorService to handle the signing of multiple transactions, and updates a core subproject dependency. A review comment suggests improving the performance of the signAllTransactions method by processing transactions concurrently using TaskGroup instead of sequentially.

[gemini-code-assist]

The current implementation processes transactions sequentially within a for loop. Since each transaction's signing process is an independent asynchronous operation, they can be executed concurrently to improve performance.

Using a TaskGroup will allow these operations to run in parallel, which can significantly reduce the total execution time when signing multiple transactions. The suggested change preserves the order of the signed transactions.

Suggested change

	var signedTransactions: [String] = []
	for data in transactions {
	let simulation = try await simulateSendTransaction(chain: chain, transactionType: type, data: data)
	let transaction = try walletConnect.decodeSendTransaction(transactionType: type, data: data)
	let signed = try await signer.signTransaction(sessionId: sessionId, chain: chain.map(), transaction: transaction.map(), simulation: simulation)
	signedTransactions.append(signed)
	}
	let signedTransactions = try await withThrowingTaskGroup(of: (Int, String).self) { group -> [String] in
	for (index, data) in transactions.enumerated() {
	group.addTask {
	let simulation = try await self.simulateSendTransaction(chain: chain, transactionType: type, data: data)
	let transaction = try self.walletConnect.decodeSendTransaction(transactionType: type, data: data)
	let signed = try await self.signer.signTransaction(sessionId: sessionId, chain: chain.map(), transaction: transaction.map(), simulation: simulation)
	return (index, signed)
	}
	}
	var indexedResults: [(Int, String)] = []
	indexedResults.reserveCapacity(transactions.count)
	for try await result in group {
	indexedResults.append(result)
	}
	return indexedResults.sorted { $0.0 < $1.0 }.map { $0.1 }
	}
