STL is a distributed digital currency trading network based on the STL protocol. STL aims to establish a diversified and integrated pass-type economy by merging and integrating resources from multiple ecological industries, forming a global ecological alliance and a vast community of nodes. This will facilitate the creation of internationally leading, fully functional ecological applications and an upgraded global financial system. Essentially, STL builds a decentralized gateway for the transfer of digital currencies among themselves and with fiat currencies, while also serving as the core for the distribution, proof-of-stake, and value exchange within its ecosystem. The STL network is built on the Paydex platform, which in turn is developed on the Stellar network. Compared to traditional networks like Bitcoin and Ethereum, it offers faster transactions, enhanced security, greater scalability, flexibility, and privacy. The STL network and Paydex Lab are located in Australia and the United States.
