Inside this simulator
Operate the custody stack under failure conditions. You reconstruct a seed phrase from partial backup, exercise a multisig quorum after a signer is lost, and decide which of hot, warm, cold, and qualified-custodian arrangements suits each client situation.
What you'll do
- Reconstruct a BIP-39 seed phrase from an incomplete backup
- Recover funds through a 2-of-3 multisig after one key is unavailable
- Compare self-custody, hybrid, and qualified-custodian models for the same client
- Document the recovery path so a successor advisor could follow it
Skills you'll evidence
- Explaining seed phrases and derivation to a client without hand-waving
- Designing a quorum that survives one lost key but not one compromised signer
- Assessing when a qualified custodian is the correct fiduciary answer
Who it's for
Advisors who are asked 'where are the coins actually kept' and need to answer with operational specifics.
Common questions
- Why does multisig matter for advisory clients?
- A 2-of-3 arrangement removes the single point of failure that destroys self-custodied wealth — one lost key no longer means lost funds — while still preventing any single party, including the advisor, from moving assets alone.
- Are real keys or funds ever used?
- Never. Every wallet, seed, and signature in this sandbox is generated for the exercise and holds nothing.
