pTokens are digital assets that are transparently pegged to another underlying asset. pTokens serve as a Cross-Chain token wrapper that allows users to more easily transfer value between different blockchains. Users can deposit a certain amount of the underlying asset (such as BTC or EOS) and request the equivalent pTokens that are pegged to them 1:1, such as pBTC or pEOS. Token holders can then take advantage of the Ethereum network by more easily exchanging them into ERC-20 tokens.

NIX is developing a cross-chain protocol with an emphasis on privacy. Their platform will be powered by the NIX coin, and will allow users to exchange supported coins with atomic swaps. Nix hopes to eliminate the need for centralized exchanges with their DEX manager. The platform is based on the Ghost Protocol, which uses elements of Zercoin, and integrates the Tor network to provide enhanced security and privacy for users. NIX allows developers create and attach their own networks to the NIX network as sidechains. The cross-chain platform has a Proof-of-Work consensus mechanism.

Wanchain is a cross-chain protocol for inter-chain transactions. It was originally a fork of Ethereum, but is now a completely separate blockchain called the WAN chain, that also has a Proof-of-Stake (PoS) consensus mechanism. Wanchain is designed to be a decentralized and interconnected platform to exchange digital assets across separate blockchains. It is meant to connect the growing number of blockchain projects and make them inter-operable.
