FAQ

SpotLab is a zk-SNARKs custodial privacy engine, enabling users and institutions to store, move, and settle digital assets with full mathematical verification but zero metadata exposure.

Every action deposit, withdrawal, swap, transfer, or bridge is verified through zero-knowledge proof circuits rather than on-chain signatures or observable traces.

Unlike mixers, SpotLab:

• Does not use transaction pooling

• Does not rely on equal denominations

• Does not expose time patterns

• Does not operate as a simple tumbler

Instead, SpotLab uses encrypted state commitments, nullifiers, and succinct proofs, working similarly to a private L2 custody engine. Privacy comes from cryptographic design, not from obfuscation.

SpotLab is custodial, but not in the traditional sense.

Balances exist only inside an Encrypted Sparse Merkle Tree (ESMT), and assets are handled through a provable zk-Solvency framework, meaning:

SpotLab cannot hide liabilities

Cannot manipulate balances

Cannot operate fractional reserves

Must prove solvency without revealing any customer data

It merges custody with cryptographic transparency.
