Augmint - Stable Digital Tokens - Solidity Contracts
Decentralised stable cryptocurrency on Ethereum
Concept
Augmint provides digital tokens, value of each token pegged to a fiat currency.
The first Augmint token will be A-EUR (Augmint Euro), pegged to EUR.
The value of 1 A-EUR is always closely around 1 EUR.
Augmint tokens are cryptocurrency tokens with all the benefits of cryptocurrencies: stored securely in a decentralised manner and instantly transferable worldwide.

Components
Flows
Sequence diagrams:
- Loan flow
- Lock flow
- Exchange flow
- Reserve Sales flow (not implemented yet)
Solidity 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)
