# 3.3 Ecosystem participants • Validators, operating nodes that confirm transactions and secure the Polygon Blockchain. • Consumers, who use SLCT to purchase goods or services. • Companies and projects, that sell their goods or services in exchange for SLCT. • Ambassadors, who spread the word and support the adoption of SmartLeCo. • The SmartLeCo Ecosystem is embedded in a comprehensive network of business partners. With such international partnerships, SLCT can reach out to millions of customers and many projects, thus supporting and accelerating global adoption. It is therefore expected that SLCT will quickly reach a substantial number of members, projects and customers within the ecosystem. Certain business partners also provide an easy exchange, rewards, and other functions which have been integrated directly into the project's Apps. • Cryptocurrency exchanges allow their users to buy and sell SLCT, among other cryptocurrencies, against fiat currencies like EUR or USD. Users must register separately with such platforms and are subject to all required Anti-Money Laundering (AML) and Know-Your-Customer (KYC) checks. In this context, cryptocurrency exchanges provide the gateway through which to convert SLCT to or from fiat and other cryptocurrencies. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
