Systems and methods are provided for creating and maintaining an ecosystem, such as for trading securities. For example, in one system, at least one eligibility prerequisite is identified—governing whether an entity is eligible to participate in the ecosystem—and whether the entity meets the eligibility prerequisite(s) is determined. In addition, at least one ecosystem rule is identified, governing whether an entity is qualified to participate in the ecosystem. An eligible entity may execute a contract in which the entity agrees to adhere to the ecosystem rule(s), thus allowing the entity to participate in the ecosystem. The entity may then enter into at least one designated ecosystem transaction, such as buying a security. Participants in the ecosystem may include issuers of securities, investors, brokers, dealers, and research analysts. In this example, the ecosystem seeks to maximize liquidity and transparency while minimizing regulatory obligations.
