Step 2 — Choose Sharding Scheme
Select how your private key will be split into shards. Each scheme offers different governance and security guarantees.
Generated Shards
Step 3 — Name Your Custodial Groups
Assign meaningful names to each shard group (e.g., CEO, CFO, Board) to communicate the governance structure.
Step 4 — Validate Shard Combinations
Verify that shard combinations correctly reconstruct the original private key. Every valid combination is tested.
Validation Results
Each row shows a combination of shards and whether the recovered address matches the original.

Step 5 — Download & Distribute
Download shards for secure offline distribution. Add an optional passphrase to encrypt shards with AES-256-GCM.
🔒Your private key never left this browser tab. All key generation, sharding, and validation ran locally using the Web Crypto API and audited @noble/* libraries. Close this tab and the key is irretrievably gone.
