This details the
publish script in the synthetix repository for building, deploying and verifying contracts.
This script can
build (compile and flatten),
verify (on Etherscan) the Synthetix code to a testnet or mainnet.
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
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 the deployment files for the associated network in "publish/deployed/
". For example, here's the "deployment.json" file for mainnet.
-a, --add-new-synthsWhether 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
flattenedwill 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.jsonfile will be written (and read from if it currently exists). The
config.jsonshould be in the following format (here's an example):
1 2 3 4 5 6 7 8
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)

Will attempt to verify the contracts on Etherscan (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.

4. Nominate New Owner¶
For all given contracts, will invoke
nominateNewOwner for the given new owner;
5. Owner Actions¶
Helps the owner take ownership of nominated contracts and run any deployment tasks deferred to them.
6. Remove Synths¶
Will attempt to remove all given synths from the
Synthetix contract (as long as they have
0) and update the
synths.json for the deployment folder.
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.
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.
Will initiate the synthetix release process, publishing the synthetix
npm module and updating all dependent projects in GitHub and
9. Staking Rewards¶
Will deploy an instance of StakingRewards.sol with the configured stakingToken and rewardsToken in rewards.json. Then
run node publish verify
synthetix repo, we are using the following branch mapping:
PRs should start being merged into
develop then deployed onto
KOVAN, then merged into
staging once deployed for releasing onto
ropsten for staging into a
mainnet release. These can be done multiple times for each branch, as long as we keep these up to date.

v3.1.9-rc3is the fourth release of a release candidate with all testnets having the deployment
v3.1.9is the mainnet release with all environments
When adding new synths¶
- In the environment folder you are deploying to, add the synth key to the
synths.jsonfile. If you want the synth to be purgeable, add
subclass: "PurgeableSynth"to the object.
- [Optional] Run
buildif you've changed any source files, if not you can skip this step.
deployas usual but add the
- To document all the files changed by a SIP, on which layers, to aid with knowing which contracts need to be deployed and where.
- To match up SIPs to releases.
How and when to update in PRs¶
- Any PRs that involve a SIP must always add an entry to
- However they should never allocate a SIP to a release (in
releaseslist) - this is done once we are ready to promote a release to kovan (and thus staging), this way, your PRs are disconnected from releases as they should be.
The fork-tests in CI will look for all sips that target the base layer and will attempt to deploy them and run the L1 integration tests on a fork.
