If you are using the payment form on snapshot.box to subscribe to Snapshot Pro, all payments are processed through our dedicated payment contract, called Schnaps.
The official Schnaps contract address is: 0xe40bfeb5a3014c9b98597088ca71eccdc27ca410
Please note:
This is the only contract address used for Snapshot Pro payments.
It is deployed only on Ethereum mainnet.
If you see a different address or chain, it is not official.
For reference, the Schnap contract code is available here:
https://github.com/snapshot-labs/schnaps
Always double-check the contract address before making a payment.
