Client assets held under Swiss law, with private keys and client data residing in Switzerland. 132 digital assets across 18 networks available at launch.
Sep 30, 2026 — Zurich, Switzerland
Cactus Custody today announced the launch of its Swiss custody service, operated by ChainTech AG, a company registered in Switzerland and a member of VQF, a self-regulatory organisation recognised by the Swiss Financial Market Supervisory Authority (FINMA).
The launch gives institutional clients the option to hold digital assets under Swiss law, alongside Cactus Custody’s existing operations in Hong Kong and Bhutan. For institutions evaluating custody arrangements, the governing jurisdiction — and what it means for how assets are treated in an insolvency — is increasingly a threshold question rather than a secondary consideration.
Why Switzerland
Switzerland’s legal framework for digital assets is among the most developed in the world. Under the amendments introduced by the Swiss DLT Act, crypto-assets held in custody for clients may be segregated from the custodian’s bankruptcy estate, subject to the conditions set out in the applicable legislation. Client assets held with ChainTech AG are segregated from the company’s own assets at both the legal and the operational level.
Switzerland also offers one of the strongest data protection regimes available to financial institutions. ChainTech AG operates in accordance with the revised Swiss Federal Act on Data Protection (nFADP).
Keys and data stay in Switzerland
The service is built around a straightforward operating principle: the material that matters most does not leave the country.
Private keys for the Swiss entity are generated and held within Swiss data centre infrastructure, on hardware security modules certified to FIPS 140-2 and FIPS 140-3 standards. They are not held or backed up outside Switzerland. Client data is stored on infrastructure located in Switzerland. Disclosure of client information to third parties occurs only where required under Swiss law and through the applicable legal process.
This is a design decision rather than a policy statement. It means that the jurisdiction governing the custody relationship, the jurisdiction holding the cryptographic material, and the jurisdiction holding the client record are the same.
Available at launch
The Swiss service launches with the full account structure available to Cactus Custody clients elsewhere:
- Segregated address accounts, supporting both warm and cold wallet configurations
- DeFi accounts, including access via Cactus Link
- ETH staking accounts
At launch, ChainTech AG supports 132 digital assets across 18 networks:
Bitcoin (BTC) · Bitcoin Cash (BCH) · Litecoin (LTC) · Dogecoin (DOGE) · Ethereum (ETH) · BNB Smart Chain (BNB) · Ethereum Classic (ETC) · Avalanche (AVAX) · Kaia (KAIA) · Optimism · Base · Arbitrum · Hyperliquid (HYPE) · TRON (TRX) · Solana (SOL) · Polkadot (DOT) · Stellar (XLM) · Sui (SUI)
Networks are added to the Swiss entity following independent legal and security assessment, and the supported list will expand on that basis. Clients with requirements outside the current list are invited to raise them with their relationship manager.
What comes next
Cactus Custody’s existing insurance coverage, provided by OneDegree, and its third-party audit reports currently apply to its Hong Kong and Bhutan entities. Extension of insurance coverage and independent audit to the Swiss entity is planned following launch, and will be confirmed separately once complete.
