# Dss Add Ilk Spell

Spell contract to deploy a new collateral type in the DSS system.

## Additional Documentation

- `dss-deploy` [source code](https://github.com/makerdao/dss-deploy)

- `dss` [source code](https://github.com/makerdao/dss)

## Deployment

### Prerequisites:

- seth/dapp (https://dapp.tools/)

- Have a DSS instance running

### Steps:

1) Export contract variables

- `export TOKEN=`

- `export PIP=`

- `export ILK="$(seth --to-bytes32 "$(seth --from-ascii "")")"`

- `export MCD_VAT=`

- `export MCD_CAT=`

- `export MCD_JUG=`

- `export MCD_SPOT=`

- `export MCD_PAUSE=`

- `export MCD_PAUSE_PROXY=`

- `export MCD_ADM=`

- `export MCD_END=`

2) Deploy Adapter (e.g. [GemJoin](https://github.com/makerdao/dss/blob/master/src/join.sol#L62))

- `export JOIN=$(dapp create GemJoin "$MCD_VAT" "$ILK" "$TOKEN")`

3) Deploy Flip Auction and set permissions (e.g. [Flipper](https://github.com/makerdao/dss/blob/master/src/flip.sol))

- `export FLIP=$(dapp create Flipper "$MCD_VAT" "$ILK")`

- `seth send "$FLIP" 'rely(address)' "$MCD_PAUSE_PROXY"`

- `seth send "$FLIP" 'deny(address)' "$ETH_FROM"`

4) Export New Collateral Type variables

- `export LINE=` (e.g. 5M DAI `"$(seth --to-uint256 $(echo "5000000"*10^45 | bc))"`)

- `export MAT=` (e.g. 150% `"$(seth --to-uint256 $(echo "150"*10^25 | bc))"`)

- `export DUTY=` (e.g. 1% yearly `"$(seth --to-uint256 1000000000315522921573372069)"`)

- `export CHOP=` (e.g. 10% `"$(seth --to-uint256 $(echo "110"*10^25 | bc))"`)

- `export LUMP=` (e.g. 1K DAI `"$(seth --to-uint256 $(echo "1000"*10^18 | bc))"`)

5) Deploy Spell

- `export SPELL=$(seth send --create out/DssAddIlkSpell.bin 'DssAddIlkSpell(bytes32,address,address[8] memory,uint256[5] memory)' $ILK $MCD_PAUSE ["${MCD_VAT#0x}","${MCD_CAT#0x}","${MCD_JUG#0x}","${MCD_SPOT#0x}","${MCD_END#0x}","${JOIN#0x}","${PIP#0x}","${FLIP#0x}"] ["$LINE","$MAT","$DUTY","$CHOP","$LUMP"])`

6) Create slate

- `seth send "$MCD_ADM" 'etch(address[] memory)' ["${SPELL#0x}"]`

7) Wait for the Spell to be elected

8) Schedule Spell

- `seth send "$SPELL" 'schedule()'`

9) Wait for Pause delay

10) Cast Spell

- `seth send "$SPELL" 'cast()'`
