The EVM slot value strategy on Snapshot X uses values stored in specific slots on an EVM chain as voting power. It retrieves data such as ERC-20 token balances or ERC-721 token ownership from Ethereum mainnet or Sepolia testnet and leverages storage proofs to verify data integrity when used on a layer 2. Currently, this strategy is only available on Starknet.
To set up this strategy, you need to:
Add the Ethereum mainnet or Sepolia testnet contract address.
Find the storage slot where balances or other relevant data are stored in the contract using https://storage.herodotus.dev.
On the Herodotus site, enter the contract address and select the network.
Locate the index where the balances or data you want to use as voting power is stored on the contract.
For example, for the ApeCoin (APE) ERC-20 token, the balances are stored in the slot index 0.
