Managed ICO solutions and smart contract development Since most new ventures are either inexperienced or don\u2019t have the time or resources to develop and audit their smart contracts, a fully managed ICO dashboard solution like COINAdmin can help ICOs with complete smart contract development and security auditing to ensure they are bug-free and reliable. COINAdmin, with its dedicated team of blockchain developers, specializes in developing smart contracts for ERC-20 and ERC-223 standards and supports extensive third-party audits &#8211; handling all the technical aspects and allowing ICO teams to focus on the business side. Given how the entirety of a token sale\u2019s collected funds and distribution of tokens depends on the reliability of the smart contract, it makes sense for ventures to opt for a dedicated, professionally developed solution, rather than going down the trial and error route. The full solution provided by COINAdmin allows projects to issue ICO tokens without requiring a solidarity programmer, saving time and money. To date, the COINAdmin team has worked with a range of crypto and blockchain ventures, which have collectively secured over $70 million in funding.
