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.

Dependencies

List of contracts

• Restricted.sol
  Stores permissions per address
• MultiSig.sol
  Abstract contract to manage multi signature approval and execution of atomic, one-off contract scripts
• StabilityBoardProxy.sol
  Augmint parameters can be set only via this contract with a quorum approving a contract script to run.
• ERC20.sol
  Standard ERC20 token interface.
• SystemAccount.sol Abstract contract to maintain balances of Augmint system accounts
• AugmintReserves
  • Holds Augmint's ETH and token reserves
• InterestEarnedAccount
  • Holds interest earning from token lending - only from repaid loans, i.e. already "earned"
  • Provides interest for Locks
• FeeAccount.sol
  • holds all fees: tokens from transfer and exchange fees (to be implemented) + ETH fees from defaulting fees
  • calculates transferFees
• AugmintToken.sol
  Base contract for all Augmint tokens, TokenAEur.sol being the first implementation.
  • ERC20 standard functions
  • maintains account token balances
  • Generic transferAndNotify "convenience" function
  • allows MonetarySupervisor to issue tokens on loan disbursement and for reserve
  • allows accounts to burn their tokens (used by repay loan and burn from reserves via MonetarySupervisor contract)
• MonetarySupervisor.sol
  • maintains system wide KPIs (totalLockAmount, totalLoanAmount)
  • enforces system wide limits (Loan to Deposit ratio limits)
  • issue to & from reserve functions
• TokenAEur.sol
  • First AugmintToken contract instance, pegged for pegged to EUR (A-EUR aka Augmint Euro aka A€ )
  • Sets standard token parameters (name, symbol, decimals, peggedSymbol etc.)
• Rates.sol
  A contract to return fiat/ETH exchange rates.
• Exchange.sol
  EUR / ETH exchange contract. Sell or buy A-EUR for ETH
• LoanManager.sol
  • Loan products and their parameters
  • Maintains all loans via new loan, repayment, collection functions
  • Holds collateral in escrow
• Locker.sol
  • Lock products and parameters
  • Token funds locking and releasing
  • Holds locked tokens (with interest)
