There are also some hybrid solutions which seek to improve the networks scalability by combining the technologies. SIBEX is an OTC dark pool that assists users in trading Bitcoin, Ethereum, and ERC 20 Tokens using hashed time-locked contracts (HTLCs). This structure makes blockchains highly decentralized systems, with pros and cons. It is important to note that most layer-2 solutions, usually, use off-chain mechanisms to increase speed and operational efficiency. MyCointainer is regulated by FUI to provide services of exchanging virtual currency against Fiat and wallet management. Layer 2 (L2) is a separate framework/blockchain built with an aim to extend the capabilities and functionalities of existing blockchain platforms. Optimistic rollups provide composability, a fundamental requirement of DeFi, though they are subject to longer wait times and potential attacks. 7.
