# Checkpoints

Checkpoints are how the DerivaDEX off-chain operators confirm and verify state and transactions with on-chain data (such as deposit and withdrawal events). You can view the current checkpoint in the stats bar at the top of the interface.

Checkpoints occur roughly every 10 minutes worth of blocks. A checkpoint contains all the exchange state, and is periodically submitted on-chain to Ethereum. \

Checkpoints are how DerivaDEX verifies withdrawals, and also enable the application to resume statefully if necessary. 

### Checkpoint technical note:

A checkpoint is the merkleized state root hash.
