Manta Network is the only ZK-Snark Privacy Layer for Web3 built on Polkadot. It focuses on the important but unsolved privacy issue, and works hard to achieving its goal of providing privacy solutions to the whole DeFi world. By taking Polkadot's advantage in interoperability, Manta's first product, MantaPay, is able to privatize the entire relay chain and parachain of Polkadot, such as the stablecoins on Acala, and the EVM digital assets on Moonbeam.
