Introduction to Bob Swap (BobVault contract)

Bob Swap 0x25E6505297b44f4817538fB2d91b88e1cF841B54 is a module for issuing BOB collateralised with other USD-pegged assets. Bob Swap has received substantial testing using USDC and USDT as collaterals along with their passive investments into AAVE. Bob Swap was initially funded for 1,000 BOB for testing purposes. This governance proposal reimburses the testing team with that amount. Each collateral in BobSwap includes the following dynamic parameters:

1. price - amount of collateral with value equal to 1 BOB (18 decimals)

2. inFee - proportional fee for buying BOB with given collateral (18 decimals, 1e18 = 100%)

3. outFee - proportional fee for selling BOB for given collateral (18 decimals, 1e18 = 100%)

4. yield - optional implementation contract for earning yield through lending markets (e.g. AAVE)

5. buffer - amount of buffer for collateral tokens to be kept outside of yield-earning market. This reduces the frequency of deposit/withdraw operations and lowers expected value of the swap transaction gas fee.

6. dust - amount of collateral tokens that cannot be withdrawn as a farmed revenue, designed to account for unexpected rounding errors within the yield protocol and accrued permanent losses (if any).

Proposal objective

After the completion of the security audit and upgrade of all contracts in the prior governance proposal Upgrade of BOB Protocol contracts to the release 1.0.0, the Bob protocol management team approved an increase of the BOB issuance limits through Bob Swap to 1,000,000 BOB, along with the following collateral configuration:USDC:

1. price - 1 (6 decimals)

2. inFee - 0.01% → 0.008% (18 decimals)

3. outFee - 0.01% (18 decimals)

4. yield - 0x59cc168654Dbb7f6874115bf47Ac7312ceCdB6de - yield earning implementation through AAVE v3 Polygon deployment

5. buffer - 100 USDC → 10,000 USDC (6 decimals)

6. dust - 0.001 USDC → 1 USDC (6 decimals)
