Staking Regulation in Switzerland — Custodial vs Non-Custodial Framework

Staking Regulation in Switzerland

Staking — the process of locking cryptocurrency in a proof-of-stake network to participate in consensus validation and earn rewards — has become a significant revenue stream for crypto institutions and a regulatory focus area for FINMA. Switzerland distinguishes between custodial staking (where a service provider holds the staked assets) and non-custodial staking (where the asset owner retains control), applying fundamentally different regulatory treatments to each model.

Custodial Staking

Custodial staking — where a financial intermediary accepts client assets, stakes them on the client’s behalf, and returns staking rewards (minus a service fee) — is limited to FINMA-licensed banks and fintech licensees. The regulatory logic: custodial staking involves holding client assets, which constitutes deposit-taking or custody services under Swiss financial market law. Only entities with appropriate FINMA licenses may accept and manage client assets.

Sygnum Bank and AMINA Bank both offer custodial staking services under their FINMA banking licenses. Clients deposit proof-of-stake assets (ETH, SOL, DOT, ADA, and others) with the bank, which operates validator nodes, manages technical operations, and distributes staking rewards to clients. The bank’s AML/KYC obligations apply to staking clients as with any other banking service.

Segregation requirements apply under the DLT Act — staked client assets must be segregated from the custodian’s own assets in bankruptcy. For staking specifically, this creates a technical challenge: staked assets are locked in the protocol’s staking contract and cannot be immediately liquidated. Slashing risk (penalty for validator misbehavior that reduces staked assets) is borne by the custodian or shared with clients according to contractual terms.

Non-Custodial Staking

Non-custodial staking — where the asset owner operates their own validator node or uses a staking service that never takes custody of the assets — is generally unregulated in Switzerland. If the service provider lacks custody of client assets, no deposit-taking or custody service is provided, and FINMA licensing is not required. Self-staking (an individual running a validator node with their own assets) has no regulatory implications beyond general tax obligations.

This distinction incentivizes non-custodial staking models. Liquid staking protocols (where users stake assets through smart contracts that issue liquid staking tokens representing the staked position) operate in a regulatory grey area — the smart contract holds custody, but no identifiable entity acts as custodian. FINMA has not issued specific guidance on liquid staking protocols, though the principle-based approach suggests that entities marketing or operating liquid staking services from Switzerland may face regulatory scrutiny if they effectively provide custody services.

Tax Treatment

Staking rewards received by private investors are generally treated as income subject to income tax — distinguishing staking from capital gains on payment tokens (which are tax-free for private investors). The rationale: staking rewards represent compensation for providing validation services, analogous to interest income rather than capital appreciation. The tax treatment depends on the specific cantonal tax authority’s classification and may vary across cantons.

For institutional stakers, staking rewards are treated as business income subject to corporate income tax. Foundations and associations with tax-exempt status may not owe income tax on staking rewards if the staking activity is conducted in furtherance of their stated purpose.

Liquid Staking and Regulatory Grey Areas

Liquid staking protocols — where users deposit assets into smart contracts that issue liquid staking tokens (LSTs) representing the staked position plus accrued rewards — present the most complex regulatory classification challenge in Swiss staking regulation. The smart contract holds custody of the staked assets, but no identifiable entity acts as traditional custodian. The liquid staking token represents a claim on the underlying staked assets plus accumulated rewards — potentially qualifying as an asset token (security) under FINMA’s classification framework.

If a Swiss-domiciled foundation or company governs a liquid staking protocol, FINMA may attribute regulatory responsibility to that entity. The analysis depends on the degree of control the entity exercises over the protocol — can it modify staking parameters, direct staked assets, or pause the protocol? If so, the entity may function as a de facto custodian and financial intermediary. If the protocol is genuinely immutable and decentralized, the regulatory classification becomes less clear.

The Federal Council’s October 2025 proposal for crypto institution licenses may clarify the regulatory treatment of liquid staking. The proposed license covers “wallet service providers” — entities that custody crypto assets for clients. If liquid staking protocols are classified as custodial services, operators would need a crypto institution license. This reclassification would affect any Swiss-domiciled entity governing a liquid staking protocol.

Staking in the Context of Proof-of-Stake Foundations

The major protocol foundations domiciled in Crypto Valley govern proof-of-stake networks where staking is integral to consensus security. The Ethereum Foundation oversees the Ethereum network, which transitioned to proof-of-stake in September 2022 (The Merge). The Cardano Foundation stewards Cardano’s Ouroboros proof-of-stake consensus. The Tezos Foundation supports the Tezos network, which has used proof-of-stake (baking) since launch. The Web3 Foundation governs Polkadot’s nominated proof-of-stake system.

These foundations do not themselves operate as staking service providers — they steward the protocol but do not stake assets for clients. However, the staking mechanisms within their protocols create the economic infrastructure that custodial staking providers (Sygnum, AMINA) offer as commercial services. The regulatory treatment of staking thus indirectly affects these foundations by shaping the institutional ecosystem surrounding their protocols.

Slashing Risk and Institutional Considerations

Slashing — the penalty imposed on validators for misbehavior (double signing, extended downtime, other protocol violations) — creates a specific risk category that custodial staking providers must manage. When a bank like Sygnum or AMINA operates validator nodes for client assets, slashing events reduce the client’s staked balance. The allocation of slashing risk between the custodian and the client must be defined in contractual terms.

FINMA’s DLT Act framework requires segregation of client assets — but slashing modifies the quantity of staked assets within the protocol, not at the custodian level. The custodian cannot prevent protocol-level slashing; it can only minimize slashing risk through proper validator operation (redundant infrastructure, key management, monitoring). Institutional staking contracts typically include slashing risk allocation clauses, insurance provisions for operational slashing (caused by the custodian’s infrastructure failures), and limitations on liability for consensus-level slashing (caused by protocol design or network-level events).

For institutional investors considering staking exposure through Swiss custodians, the AML/KYC compliance of the custodian, the DLT Act’s bankruptcy protections for staked assets, and the custodian’s operational track record on slashing avoidance are key due diligence factors. Pension funds and insurance companies subject to FINMA investment regulations must also assess whether staking exposure is permissible within their investment mandates.

Comparison: Custodial vs Non-Custodial Staking

The regulatory distinction between custodial and non-custodial staking creates distinct market segments with different risk-return profiles. Custodial staking through FINMA-licensed banks offers regulatory protection (segregation rules, banking supervision, deposit insurance for fiat components), operational convenience (the bank manages all technical operations), and compliance certainty (the bank handles AML/KYC obligations). The cost is typically a service fee of 5-20% of staking rewards, plus reduced yield compared to non-custodial alternatives.

Non-custodial staking offers higher yields (no intermediary fee), full asset control (the staker retains private keys), and regulatory simplicity (no FINMA licensing required). The costs are operational complexity (running validator infrastructure, managing key security), slashing risk management (the staker bears full slashing responsibility), and limited recourse (no regulated custodian to claim against if assets are lost or stolen).

Our detailed custodial vs non-custodial staking comparison analyzes these trade-offs across multiple dimensions including yield, risk, regulatory treatment, and institutional suitability. For DAO foundations managing treasury assets, the choice between custodial and non-custodial staking involves fiduciary considerations — the foundation board must assess whether the higher yield from non-custodial staking justifies the operational risk, given the board’s duty of care under Swiss foundation law.

Validator Economics and Market Structure

The Swiss staking market operates within a broader validator economics framework where reward rates, operational costs, and competitive dynamics shape the landscape. For Ethereum staking, annual rewards of approximately 3-4% (varying with total ETH staked and network activity) must cover validator infrastructure costs (hardware, bandwidth, monitoring), regulatory compliance costs (for custodial operators), and provide sufficient margin to attract institutional capital. The economics favor scale — larger staking operations achieve lower per-unit costs through infrastructure optimization and compliance cost distribution. Swiss-licensed banks (Sygnum, AMINA) benefit from existing compliance infrastructure and banking relationships that reduce the incremental cost of adding staking services to their regulated product suites. The validator economics differ significantly across proof-of-stake protocols — Ethereum, Solana, Polkadot, Cardano, and Tezos each have distinct reward structures, slashing parameters, and minimum stake requirements that affect the commercial viability of custodial staking services.

Future Regulatory Development

The staking regulatory landscape will evolve alongside the Federal Council’s 2025 proposals and FINMA’s ongoing principle-based assessments. Key developments to monitor include FINMA guidance on liquid staking protocol classification, the crypto institution license’s applicability to staking service providers, the Swiss crypto tax framework’s treatment of staking rewards in DeFi contexts, and international regulatory convergence on staking classification through FATF and BIS guidance.

Institutional Staking Market Size and Growth

The Swiss institutional staking market has grown substantially since Sygnum Bank and AMINA Bank began offering custodial staking services. As proof-of-stake networks matured and institutional comfort with staking increased, assets under staking at Swiss banks have expanded into the hundreds of millions of CHF. Ethereum’s transition to proof-of-stake in September 2022 was the catalyst for institutional staking adoption, as the network’s approximately $200 billion market capitalization became stakeable for the first time. Swiss banks were among the first globally to offer regulated Ethereum staking, leveraging their existing FINMA banking licenses to provide compliant custody and staking services.

The total value locked in staking across all proof-of-stake networks exceeds $150 billion globally, with Ethereum alone accounting for over $100 billion in staked value. Switzerland’s share of institutional staking flows is significant relative to its market size, reflecting the competitive advantage of offering staking within a FINMA-regulated banking framework that satisfies institutional compliance requirements.

Restaking and Eigenvalue Layer Analysis

Restaking protocols — where already-staked assets are committed to additional security obligations for secondary protocols — represent an emerging regulatory question for Swiss supervisors. EigenLayer on Ethereum enables restaking of ETH to provide security for external services, generating additional yield but introducing additional slashing risk. The regulatory classification of restaking under FINMA’s framework remains uncertain. If restaking is classified as a form of financial intermediation (the restaking protocol accepts custody of staked assets and deploys them to generate yield), entities operating restaking services from Switzerland may face licensing obligations. If restaking is classified as a purely technical delegation of validation duties, it may remain outside the regulatory perimeter. Swiss-domiciled entities participating in restaking governance should seek FINMA pre-consultation to clarify their regulatory position before committing significant treasury assets to restaking strategies.

DLT Act Segregation and Staking Insolvency Protection

The DLT Act’s segregation provisions are particularly relevant for custodial staking. When a FINMA-licensed bank stakes client assets, those assets must be identifiable as client property and protected in the bank’s insolvency, even though the assets are locked in protocol staking contracts. The DLT Act’s explicit provisions for digital asset segregation provide the legal certainty that institutional investors require, ensuring that staked client assets are not available to the bank’s general creditors in bankruptcy. This legal protection distinguishes Swiss custodial staking from staking services offered in jurisdictions without equivalent digital asset segregation law, providing a measurable risk reduction that institutional investors incorporate into their staking service provider selection.

Staking Tax Optimization for Protocol Foundations

For tax-exempt protocol foundations domiciled in Zug, staking their native tokens generates income that is not subject to income tax under their tax-exempt status. This creates a significant advantage for foundation-operated staking compared to taxable entities, as the full staking yield accrues to the foundation’s treasury without tax leakage. The Tezos Foundation and other protocol foundations that operate validators or delegate staking benefit from this tax efficiency, which enhances the long-term sustainability of their treasury management strategies.
