The Amp token is a digital collateral token that is specifically designed to enable the decentralized collateralization of digital asset transactions. It evolved from what was previously known as the Flexacoin network, and is meant to allow the token to better facilitate recent innovations related to borrowing and lending in the DeFi space. The Amp token's supply was created by burning the existing supply of Flexacoins, which were exchanged for the new token at a rate of 1:1. Amp will improve upon Flexacoin’s collateralization features with a new architecture that will allow for the implementation of additional on-chain supply operations and more collateral-related DeFi options.

Eternal is a Japanese cryptocurrency project that consists of Eternal Coin (XEC) and Eternal Token (XET). The project appears to be primarily focused on remittance payments, but can also be used as a medium of exchange for other purposes. XEC holders receive weekly dividend payments, and can only be traded through the company's authorized exchanges. XET was created to allow users to trade XEC on other crypto exchanges. 1 XET=10 XEC.

Viacoin is an open source cryptocurrency based on the Bitcoin protocol. Viacoin has a 24 second block time and relatively fast transaction times. It can handle 175 transactions per second without scaling through Segwit or the Lightning Network. The fast transaction times make Viacoin a good option for sending micropayments. The platform also enables users to perform cross-chain atomic swaps between different cryptocurrencies, without a centralized exchange. Viacoin has an Auxiliary Proof-of-Work (AuxPoW) consensus mechanism that allows miners to mine multiple coins, that use the Scrypt algorithms, at the same time. Viacoin's smart contract platform, Rootstock, is compatible with Ethereum smart contracts.
