Close the loop. Walk a digital executor through custody recovery and complete the estate planning capstone.
Course 4 closes the loop on the problem most estate plans ignore: cryptographic control does not transfer through a will. You practise custody recovery and then run the full digital-executor capstone.
What you'll be able to do
Design custody arrangements that survive a lost key without creating a single point of compromise
Build a digital-asset inventory clients will maintain while living
Sequence an executor's access, valuation, and transfer steps
Establish date-of-death valuation for illiquid on-chain assets
Format. A custody and multisig recovery sandbox followed by the estate transition capstone, the longest exercise in the program.
End-to-end inheritance scenario tying every prior skill together.
Simulators run in a fully sandboxed environment — no real funds, no real client data. Create an account to begin working through them at your own pace.
