Solana Adapter (@openzeppelin/contracts-ui-builder-adapter-solana)

This package provides the ContractAdapter implementation for the Solana blockchain for the UI Builder.

Note: While the basic structure is in place, including network configuration definitions, the core adapter logic for Solana-specific operations is currently a placeholder and will be implemented in future development phases.

It is intended to be responsible for:

• Implementing the ContractAdapter interface from @openzeppelin/contracts-ui-builder-types.
• Defining and exporting specific Solana network configurations (e.g., Mainnet Beta, Devnet, Testnet) as SolanaNetworkConfig objects. These are located in src/networks/ and include details like RPC endpoints, cluster information, explorer URLs, and commitment levels.
• Loading Solana program IDLs (Instruction Description Language).
• Mapping Solana-specific data types to the form field types.
• Parsing user input into Solana-compatible transaction instructions, according to the SolanaNetworkConfig.
• Formatting results from on-chain program queries.
• Interacting with Solana wallets (e.g., via @solana/wallet-adapter-base) for signing and sending transactions on the configured network.
• Providing other Solana-specific configurations and validation.

Usage

Once fully implemented, the SolanaAdapter class will be instantiated with a specific SolanaNetworkConfig object:

// Example: import { solanaMainnetBeta } from '@openzeppelin/contracts-ui-builder-adapter-solana';
import { SolanaAdapter } from '@openzeppelin/contracts-ui-builder-adapter-solana';
import { SolanaNetworkConfig } from '@openzeppelin/contracts-ui-builder-types';

// For type access if needed

// Placeholder: Actual network config objects would be imported from './networks'
const placeholderNetworkConfig: SolanaNetworkConfig = {
  id: 'solana-devnet',
  name: 'Solana Devnet',
  ecosystem: 'solana',
  network: 'solana',
  type: 'devnet',
  isTestnet: true,
  rpcEndpoint: 'https://api.devnet.solana.com',
  explorerUrl: 'https://explorer.solana.com/?cluster=devnet',
  commitment: 'confirmed',
  // ... any other SolanaNetworkConfig fields
};

const solanaAdapter = new SolanaAdapter(placeholderNetworkConfig);

// Use solanaAdapter for operations on the configured Solana network

Network configurations for Solana networks (e.g., solanaMainnetBeta, solanaDevnet) are defined and exported from src/networks/index.ts within this package. The full list is exported as solanaNetworks.

Internal Structure

This adapter follows the standard module structure outlined in the main project Adapter Architecture Guide, with the src/networks/ directory for managing its network configurations.
