• helius_get_balance: Get the balance of a Solana wallet address.
• helius_get_block_height: Get the current block height of the Solana blockchain.
• helius_get_slot: Get the current slot of the Solana blockchain.
• helius_get_latest_blockhash: Get the latest block hash.
• helius_get_transaction: Get transaction details by transaction signature.
• helius_get_account_info: Get information about a Solana address.
• helius_get_signatures_for_address: Get transaction signatures related to a Solana address.
