Notice

This details the publish script in the oikos repository for building, deploying and verifying contracts.

Imported from https://github.com/oikos-cash/oikos-bsc/tree/master/publish

Publisher

This script can build (compile and flatten), deploy and verify (on Bscscan) the Oikos code to a testnet or mainnet.

1. Build

Will compile bytecode and ABIs for all .sol files found in node_modules and the contracts folder. It will output them in a compiled folder in the given build path (see below), along with the flattened source files under the folder flattened.

# build (flatten and compile all .SOL sources)
node publish build # "--help" for options

2. Deploy

Will attempt to deploy (or reuse) all of the contracts listed in the given contract-flags input file, as well as perform initial connections between the contracts.

:warning: This step requires the build step having been run to compile the sources into ABIs and bytecode.

Note: this action will update in place both the contract-flag input file and the contract addresses output (here's the rinkeby one for example) in real time so that if any transactions fail, it can be restarted at the same place.

# deploy (take compiled SOL files and deploy)
node publish deploy # "--help" for options

CLI Options

  • -a, --add-new-synths Whether or not any new synths in the synths.json file should be deployed if there is no entry in the config file.
  • -b, --build-path [value] Path for built files to go. (default of ./build - relative to the root of this repo). The folders compiled and flattened will be made under this path and the respective files will go in there.
  • -c, --contract-deployment-gas-limit <value> Contract deployment gas limit (default: 7000000 (7m))
  • -d, --deployment-path <value> Path to a folder that has your input configuration file (config.json), the synths list (synths.json) and where your deployment.json file will be written (and read from if it currently exists). The config.json should be in the following format (here's an example):
// config.json
{
  "ProxyoUSD": {
    "deploy": true // whether or not to deploy this or use existing instance from any deployment.json file
  },

  ...
}

Note: the advantage of supplying this folder over just usi`ng the network name is that you can have multiple deployments on the same network in different folders

  • -g, --gas-price <value> Gas price in GWEI (default: "1")
  • -m, --method-call-gas-limit <value> Method call gas limit (default: 150000)
  • -n, --network <value> The network to run off. One of mainnet, kovan, rinkeby, rospen. (default: "kovan")
  • -o, --oracle <value> The address of the oracle to use. (default: 0xac1e8b385230970319906c03a1d8567e3996d1d5 - used for all testnets)
  • -f, --fee-auth <value> The address of the fee Authority to use for feePool. (default: 0xfee056f4d9d63a63d6cf16707d49ffae7ff3ff01 - used for all testnets) --oracle-gas-limit (no default: set to 0x5a556cc012642e9e38f5e764dccdda1f70808198)

Examples

# deploy to rinkeby with 8 gwei gas
node publish deploy -n ropsten -d publish/deployed/ropsten -g 20
node publish deploy -n rinkeby -d publish/deployed/rinkeby -g 20
node publish deploy -n kovan -d publish/deployed/kovan -g 8
node publish deploy -n local -d publish/deployed/local -g 8

3. Verify

Will attempt to verify the contracts on Bscscan (by uploading the flattened source files and ABIs).

:warning: Note: the build step is required for the ABIs and the deploy step for the live addresses to use.

# verify (verify compiled sources by uploading flattened source to Bscscan via their API)
node publish verify # "--help" for options

Examples

# verify on mainnet
export BSCSCAN_KEY=...
node publish verify -n bsc -d publish/deployed/bsc

4. Nominate New Owner

For all given contracts, will invoke nominateNewOwner for the given new owner;

node publish nominate # "--help" for options

Example

node publish nominate -n rinkeby -d publish/deployed/rinkeby -g 3 -c Oikos -c ProxyoUSD -o 0x0000000000000000000000000000000000000000
node publish nominate -o 0xB64fF7a4a33Acdf48d97dab0D764afD0F6176882 -n kovan -c ProxyoUSD -d publish/deployed/kovan -g 20

5. Owner Actions

Helps the owner take ownership of nominated contracts and run any deployment tasks deferred to them.

node publish owner # "--help" for options

6. Remove Synths

Will attempt to remove all given synths from the Oikos contract (as long as they have totalSupply of 0) and update the config.json and synths.json for the deployment folder.

node publish remove-synths # "--help" for options

Example

node publish remove-synths -n rinkeby -d publish/deployed/rinkeby -g 3 -s sRUB -s sETH

7. Replace Synths

Will attempt to replace all given synths with a new given subclass. It does this by disconnecting the existing TokenState for the Synth and attaching it to the new one.

node publish replace-synths # "--help" for options

7. Purge Synths

Will attempt purge the given synth with all token holders it can find. Uses the list of holders from mainnet, and as such won't do anything for other networks.

node publish purge-synths # "--help" for options

When adding new synths

  1. In the environment folder you are deploying to, add the synth key to the synths.json file. If you want the synth to be purgeable, add subclass: "PurgeableSynth" to the object.
  2. [Optional] Run build if you've changed any source files, if not you can skip this step.
  3. Run deploy as usual but add the --add-new-synths flag
  4. Run verify as usual.

Additional functionality

Generate token file

Th generate-token-list command will generate an array of token proxy addresses for the given deployment to be used in the Oikos website. The command outputs a JSON array to the console.

# output a list of token addresses, decimals and symbol names for all the token proxy contracts
node publish generate-token-list -d publish/deployed/mainnet

CLI Options

  • -d, --deployment-path <value> Same as deploy step above.

Example

node publish generate-token-list -d publish/deployed/rinkeby/ > token-list.json
