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.

  • 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
