This is a template "Hedgeware" repo with the proposed Hedgeware distribution outlined in the announcement post. To be honest and up-front this proposal has not seen community consensus and so this shouldn't be expected yet to see the light of day. Nonetheless, it has reached the MOST consensus and this repo serves as the work in progress that is the only currently worked-on parachain node for an Edgeware canary network.
Myself, Drew, and Nathan aren't terribly opinionated about launch, rather exploring actual deployment paths to see parachain work grow in the Edgeware community. We welcome any contributors in the Edgeware community to help test and provide tools towards that goal. We do not guarantee any final output for this project. The node is in its current form ready to be deployed by the right community member.
With that out of the way...
The parachain repos are coordinated around branches such as polkadot-v0.9.X on the Substrate & Cumulus and release-v0.9.X on the Polkadot repos respectively. It is good practice that we follow that here, while using main to represent the best, currently working version of the node against the most up-to-date upstream versions. Currently, we have our latest work on polkadot-v0.9.4 and related branches.
In order to update to something like polkadot-v0.9.5 and releaes-v0.9.5 the process is quite simple barring any upstream changes.
- Convert all references to
v0.9.4tov0.9.5. - Run cargo update.
- Build the node and fix any errors.
- Use the
cumlulus/polkadot-parachainsrepo as a starting point to address discrepencies / errors.
One of the first errors you will encounter is Frontier. We aim to cover this topic below.
Frontier EVM and its relevant RPCs are still quite far behind in Substrate. They are currently pegged to a branch called frontier that last saw an update in March. Therefore, any parachain node needs to use a fork of this and update that Frontier repo to the respective 0.9.X. Today, we are using the fork in @webb-tools. It has some features also not merged into Frontier, mainly updating the dynamic-fee-pallet to the Substrate 3.0 macro structure. This causes noticeable changes to the service file of this node and should be dealt with with care. Any fork can suffice.
- Create a fork of Frontier or use @webb-tools/frontier as a starting point.
- Update the references to the relevant
polkadot-v0.9.Xof Substrate (note here we only need to update Substrate branches). - Push the fork.
- Update the Hedgeware Frontier dependencies to the right fork.
- Rebuild and fix errors as they arise.
Ensure you have all relevant dependencies for building the repo. The latest work so far is pegged to polkadot-v0.9.4 and release-v0.9.4 branches of Substrate, Cumulus, and Polkadot respectively.

Optionally, for faster setup you can run:
cargo build --release
./scripts/build_specs.sh
To run against your local chainspec:
# Run vanilla execution (requires having keys set through separate means)

./target/release/hedgeware-collator --alice --collator --chain=hedgeware.chainspec.json
# Execute as Bob (default aura collator)
./target/release/hedgeware-collator --bob --collator --chain=hedgeware.chainspec.json

This will produce a file called allocations.json in the root directory, following the quaddrop allocation (balances are quadratically mapped and then totaled out to 5m). You should move it to quaddrop/allocation/dump.json.
You may wish to adjust getHedgewareDistribution.js to reflect any other allocation, such as a direct hard spoon.
