oSnap

Combine Safe with Snapshot using oSnap.

oSnap is being deprecated, and support for the product will end on December 15, 2025. To ensure continued functionality, please follow the migration guide here: https://help.snapshot.box/en/articles/12886075-osnap-deprecation-migration-guide

“oSnap” is short for Optimistic Snapshot Execution. oSnap lets DAOs propose transactions, do an off-chain governance vote, and have the transaction data submitted in a trustless fashion.

Instructions for using oSnap

Setting up the oSnap module:

• Create a Safe and Snapshot Space, or connect to your current accounts.

• Go to Safe Apps, install the Zodiac app, and install the oSnap module through Zodiac.

• Set the proposal bond, challenge period, and Snapshot Space.

• Link the oSnap module to your Snapshot Space with SafeSnap.

• Your oSnap module address is added to the SafeSnap plugin configuration to enforce the results of proposals on-chain.

Using oSnap with Snapshot:

• Create a proposal and Snapshot vote, along with the transactions to execute if the proposal passes.

• Invite the community to vote on the proposal.

• Once the Snapshot voting period ends, anyone can propose the transactions by posting a bond.

• After the challenge period, execute the transactions on-chain through the Snapshot interface.

Security recommendations

In order to ensure maximal safety we recommend to define several paremeters for your oSnap setup:

• Set a substantial bond for an answer

• Select a long challenge period

• Set up a monitoring infrastructure for proposed transactions
