Implementation Reference

• src/handlers/solana-handlers.ts:288-303 (handler)

  Handler execution logic for the 'get_solana_balance' tool within the handleSolanaTool switch statement, which extracts input parameters, calls SolanaService.getBalance, and formats the response.

  case 'get_solana_balance': {
    const address = args?.address as string;
    const network = (args?.network as 'mainnet' | 'testnet') || 'mainnet';
  
    const result = await solanaService.getBalance(address, network);
  
    return {
      content: [
        {
          type: 'text',
          text: JSON.stringify(result, null, 2),
        },
      ],
      isError: !result.success,
    };
  }

• src/handlers/solana-handlers.ts:57-75 (registration)

  Tool registration definition for 'get_solana_balance', returned by registerSolanaHandlers and included in the server's tools list.

  {
    name: 'get_solana_balance',
    description: 'Get SOL balance for a Solana address',

        network: {
          type: 'string',
          enum: ['mainnet', 'testnet'],
          description: 'Network type (defaults to mainnet)',
        },
      },
      required: ['address'],
    },
  },

• src/services/solana-service.ts:197-232 (helper)

  Core implementation in SolanaService.getBalance: retrieves Solana RPC service, calls 'getBalance' RPC method, converts lamports to SOL, and returns formatted response.

  async getBalance(
    address: string,
    network: 'mainnet' | 'testnet' = 'mainnet'
  ): Promise<EndpointResponse> {
    const service = this.blockchainService.getServiceByBlockchain('solana', network);
  
    if (!service) {
      return {
        success: false,
        error: `Solana service not found for ${network}`,
      };
    }
  
    const result = await this.blockchainService.callRPCMethod(
      service.id,
      'getBalance',
      [address]
    );
  
    if (result.success && result.data?.value !== undefined) {
      const lamports = result.data.value;
      const sol = lamports / 1e9; // 1 SOL = 1 billion lamports
  
      return {
        success: true,
        data: {
          address,
          lamports,
          sol,
        },
        metadata: result.metadata,
      };
    }
  
    return result;
  }
