Snapshot strategies

Development

Install dependencies

yarn

Build package

yarn build

Test strategy with predefined tests (params from examples.json file)

Note: If you're writing a new strategy, make sure to add it to strategies/index.ts before testing*

# Test default strategy (erc20-balance-of)
yarn test
# Test strategy with name
yarn test --strategy=erc20-received
yarn test --strategy=eth-balance
# Test with more addresses from addresses.json
yarn test --strategy=eth-balance --more=200

Test validation with predefined tests (params from examples.json file)

yarn test:validation --validation=basic

Test strategy with different parameters

Change values inside test/scores.ts and run

ts-node test/scores.ts

Checklist for adding a new voting strategy or validation strategy

Here is a simple checklist to look at when reviewing a PR for a new strategy:

Overview

• The strategy must be unique.
• If the strategy does only a single call with an address as input, it's preferable to use the strategy "contract-call" instead of creating a new one.
• For validations better to use basic validation and use existing strategies

Code

• Strategies should always use a snapshot to calculate user's voting power. As a result the voting power should not change throughout the proposal duration.
• There should be a maximum of 5 requests, a request can use "fetch" a "subgraphRequest" or "multicall".
• The strategy should not send a request for each voters, this doesn't scale.
• The strategy PR should not add any new dependency.
• The score returned by the strategy should use the same casing for address as on the input, or should return checksum addresses.
• Make sure that voting power of one address does not depend on other addresses.

Example

• Example must include at least 1 address with a positive score.
• Example must use a snapshot block number in the past.

Test

• The strategy should take less than 10sec to resolve.
• The strategy should work with 500 addresses. Here is a list of addresses.

Recommended

• Add a README.md file that describes the strategy and provides an example of parameters.
• Use string ABI instead of object.
