Lock-and-mint vs burn-and-mint threat models

This section covers lock-and-mint vs burn-and-mint threat models. Content for this lesson is being developed by our practitioner team and will be available when the program launches.

02

Message-passing layer attack surface (LayerZero, CCIP, Wormhole)

This section covers message-passing layer attack surface (layerzero, ccip, wormhole). Content for this lesson is being developed by our practitioner team and will be available when the program launches.

03

Replay, finality, and reorg assumptions across L1s and L2s

This section covers replay, finality, and reorg assumptions across l1s and l2s. Content for this lesson is being developed by our practitioner team and will be available when the program launches.
