The physical property is insured against standard risks: fire, natural disasters, water damage, and third-party liability. Insurance is contracted at the SPV level.
However, there is no insurance on investment performance. Neither Netok nor any third party guarantees rental income, token value, or capital preservation. Bank deposit guarantee schemes (such as esisuisse in Switzerland, which protects bank deposits up to CHF 100,000) do not apply to security tokens.
In self-custody, you bear sole responsibility for private key security. In custodial arrangements, the Swiss DLT Act provides for segregation of crypto-based assets from the custodian's bankruptcy estate.
