Boost Creation

UI flow to create boost:

1. Go to a space that has boost enabled (still in beta)
2. Go to any open proposal and click on "Boost"
3. Which will take us to a page like https://snapshot.org/#/thanku.eth/boost/0x25487e3e1ea520e40114a245cf59583a8e05389e5ae48a8746deab29b000af73
4. We have different configurations as seen in this page

Steps to create a boost programmatically

1. Pinning to IPFS

We need to pin a JSON file to IPFS, Example:

{
  "name": "Boost",
  "description": "Snapshot.org proposal boost",
  "image": "https://snapshot.org/boost.png",
  "external_url": "https://snapshot.org/#/thanku.eth/proposal/0x25487e3e1ea520e40114a245cf59583a8e05389e5ae48a8746deab29b000af73",
  "strategyName": "proposal",
  "params": {
    "version": "0.0.1",
    "env": "snapshot",
    "proposal": "0x25487e3e1ea520e40114a245cf59583a8e05389e5ae48a8746deab29b000af73",
    "eligibility": {
      "type": "incentive"
    },
    "distribution": {
      "type": "weighted"
    }
  }
}

Change following parameters:

• external_url: Proposal URL on snapshot
• params.proposal: Proposal ID
• params.eligibility.type: Type of eligibility
  • incentive (Any one who votes)
  • prediction (Any one who votes for the winning choice)
  • bribe (Any one who votes for a particular choice)
• params.eligibility.choice: Choice to boost (Pass it only if type is bribe)
• params.distribution.type:
  • weighted (Distributed based on voting power)
  • lottery (Randomly selected based on voting power)
• params.distribution.limit (optional for all types):
  • (If type is weighted) Max reward (value based on decimal value of token)
  • (iIf type is lottery) Max % chance to win * 100 (for example if user has max chance of 50% then value will be 5000
• params.distribution.numWinners: (If type is lottery) Number of winners that can be selected randomly

2. Deposit and mint:

In order to reward users, boost creater should deposit ERC20 tokens to snapshot's boost contract: 0x8e8913197114c911f13cfbfcbbd138c1dc74b964

Boost contract is deployed on following networks

• Ethereum (mainnet)
• Polygon PoS
• Base
• Sepolia testnet

After selecting the token:

1. Approve spending cap for token => Use approve method
2. Mint the boost => Use mint method with following parameters

Param	Type	Notes	Example
_strategyURI	string	Pinned IPFS URL	ipfs://QmUP7M525N6Bb145HvhKP8hSZBkNNij8oss7HyqiFDbWTv
_token	address	ERC20 token contract address	0xe485E2f1bab389C08721B291f6b59780feC83Fd7
_amount	uint256	Amount of token	3000000000000000000000
_owner	address	Boost creator address	0xb97d9350F32C1366016e2C0a55E4A210D1158b22
_guard	address	Can be always 0x064417ab192edC00E791d5911ecDbb7c9a718383	0x064417ab192edC00E791d5911ecDbb7c9a718383
_start	uint48	Claiming period start time = Proposal end date	1714906236
_end	uint48	Claiming period end time = Two weeks from proposal end	1716115836

3. Once transaction is successful, you should be able to see boost on the proposal
