KyberDao Katana

Architecture

General Information

The overall architecture is based off Aave's governance model with some notable modifications:

• enabling the creation and voting on multi-option (generic) proposals
• pulling voting power from the KyberStaking contract instead of a token contract
• permissioned roles like owner & guardian have been replaced by admin and daoOperator with new authorization scopes
• block timestamps utilised instead of block numbers

KyberGovernance

Handles the queueing, creation, cancellation and vote submissions for binary and generic proposals.

• executors whitelisted: Executor (short) and Executor (long)
• admin (able to authorize/unauthorize executors and voting strategies): Executor (long)
• daoOperator (able to create and cancel proposals): Kyber multisig

Executor (short)

• admin (the only address enable to interact with this executor): KyberGovernance
• delay (time between a proposals passes and its actions get executed): 12 hours
• grace period (time after the delay during which the proposal can be executed): 4 days
• minimum voting duration: 4 days
• maximum voting options: 8
• vote differential: 0.01%
• quorum: 4%

Executor (long)

Controls upgradeability of the new KNC token contract, and any change in key parameters of KyberGoverance or itself

• admin: KyberGovernance
• delay: 1 week
• grace period: 7 days
• minimum voting duration: 7 days
• maximum voting options: 8
• vote differential: 15%
• quorum: 20%

KyberVotingPowerStrategy

Calculates voting power from KNC stakes in KyberStaking. Also handles epoch validation checks for proposal creations. Will call KyberGovernance to modify vote counts due to KNC staking withdrawals.

• maxVotingPower: total KNC supply at time of proposal creation

ProposalValidator (inherited by executors)

Validates the creation and cancellation of proposals. Also determines resolutions to binary proposals.

Compilation

yarn c to compile contracts for all solidity versions.

Contract Deployment / Interactions

For interactions or contract deployments on public testnets / mainnet, create a .env file specifying your private key and infura api key, with the following format:

PRIVATE_KEY=0x****************************************************************
INFURA_API_KEY=********************************

Testing with Hardhat

1. If contracts have not been compiled, run yarn c. This step can be skipped subsequently.
2. Run yarn test
3. Use ./tst.sh -f for running a specific test file.

Example Commands

• yarn test (Runs all tests)
• ./tst.sh -f ./test/kyberGovernance.js (Test only kyberGovernance.js)

Example

yarn hardhat test ./test/kyberGovernance.js

Coverage

yarn coverage (Runs coverage for all applicable files)
