Augmint - Stable Digital Tokens - Solidity Contracts

Decentralised stable cryptocurrency on Ethereum

Concept

Decentralized stablecoins targeted to fiat currencies built on Ethereum.

The first Augmint token is AEUR.

1 AEUR ≈ 1 EUR.

Buy and sell AEUR for ETH or EUR.
Get a loan in AEUR by depositing ETH.
Lock AEUR to earn a premium.
