OWL Token

The OWL token and related smart contracts.

The token and contract can be in Etherscan:

* Mainnet:
* TokenOWL: https://etherscan.io/token/0x694c68c7577a9a6a8cf2f6da0066790201afc260
* TokenOWLProxy: https://etherscan.io/token/0x1a5f9352af8af974bfc03399e3767df6370d82e4
* OWLAirdrop: https://etherscan.io/token/0x85e9fc8273b1ee9d81f4b800071563096f689863
* Rinkeby:
* TokenOWL: https://rinkeby.etherscan.io/token/0xff9874588b2358704832a380ca9892f0a1c57b40
* TokenOWLProxy: https://rinkeby.etherscan.io/token/0xa7d1c04faf998f9161fc9f800a99a809b84cfc9d
* OWLAirdrop: https://rinkeby.etherscan.io/token/0x9b816eb9fa1af7bc57a4d7ce059ed072d49d7830
* Kovan:
* TokenOWL: https://kovan.etherscan.io/token/0xa98fdb77b578f30d5d88b3ebc2600bfe67fa09d1
* TokenOWLProxy: https://kovan.etherscan.io/token/0xb6f77a34ff81dd13fa68b5774d74541a61047fe8
* OWLAirdrop: https://kovan.etherscan.io/token/0x45ce24c27f2442feb62f62bfb26ab161f07adc71

Setup and show the networks

``bash

Install dependencies

yarn install

Compile and restore the network addresses

yarn restore

Show current network addresses

yarn networks
`

Execute migrations into a local ganache-cli

`bash

Run ganache CLU

yarn rpc

Execute the migrations

yarn migrate

Or you can do all at once using

yarn migrate-all
`

Change the lock period time - re-deployment

The deployment script has an environemt variable LOCK_END_TIME that
allows you to set a different lock period (30 days by default).

`bash


Deploy for develop with a given end time for lock period

flag --reset is NECESSARY as you are re-deploying

24H format, please be careful!

LOCK_END_TIME='2018-06-12T16:00:00+02:00' yarn migrate --reset
(npm) > LOCK_END_TIME='2018-06-12T16:00:00+02:00' npm run migrate -- --reset
`

Generate a new version

`bash

In a release branch (i.e. release/vX.Y.X)

Migrate the version to the testnets, at least rinkeby, and posibly mainnet

You can optionally change the gas price using the GAS_PRICE_GWEI env variable

if you are changing LOCK_END_TIME here, flag --reset is NECESSARY as you are re-deploying

yarn restore
MNEMONIC=$MNEMONIC_OWL yarn migrate --network rinkeby
(npm) > MNEMONIC=$MNEMONIC_OWL npm run migrate -- --network rinkeby

Extract the network file

yarn networks-extract

Verify the contract in Etherscan

Folow the steps in "Verify contract"

Commit the network file

git add networks.json
git commit -m 'Updated the networks file'
> OR simply git commit -am 'Updated networks file'

Generate version using Semantic Version: https://semver.org/

For example, for a minor version

npm version minor
git push && git push --tags

Deploy npm package

npm publish --access=public

Merge tag into develop, to deploy it to production, also merge it into master

git checkout develop
git merge vX.Y.X
`

Verify contract manually

> NOTE: For mainnet is better to use the automatic verification script (see next section)

Flatten the smart contract:
`bash
npx truffle-flattener contracts/TokenOWL.sol > build/TokenOWL-EtherScan.sol
npx truffle-flattener contracts/TokenOWLProxy.sol > build/TokenOWLProxy-EtherScan.sol
npx truffle-flattener contracts/OWLAirdrop.sol > build/OWLAirdrop-EtherScan.sol
`

Go to Etherscan validation page:
* Go to[https://rinkeby.etherscan.io/verifyContract?a=]()
* Fill the information:
* Use build/TokenOWL-EtherScan.sol
* Set the exact compiler version used for the compilation i.e. v0.4.24+commit.e67f0147
* Optimization: No
* Press validate

Verify contract automatically (mainnet only)

You can use verify-on-etherscan

> NOTE: To use the verify You'll need to create an API Key in Etherscan for this step.

`bash
API_KEY=your-etherscan-api-key yarn verify
`

Change the owner

There's a script to change the OWL owner:

For example, to change the owner in rinkeby to 0xb65d2c1a4756ee857fca057ef561758b42277f5e:
`bash


Dry run

MNEMONIC=$MNEMONIC_OWL yarn change-owner --owner 0xb65d2c1a4756ee857fca057ef561758b42277f5e --network rinkeby --dry-run

Run the transaction

MNEMONIC=$MNEMONIC_OWL yarn change-owner --owner 0xb65d2c1a4756ee857fca057ef561758b42277f5e --network rinkeby
