AMINA Bank AG has introduced a supervised staking service for Polygon’s POL token aimed at institutional clients. Announced on 9 October 2025, the product operates under Swiss law alongside FINMA rules and advertises an annual return of up to fifteen per cent. It offers a regulated way for asset managers, family offices, corporate treasuries and pension funds to help secure the Polygon network.
The yield is split between a base reward and a time-based bonus: the bank cites a base return of about four to five per cent, plus an additional bonus paid only if the client maintains the stake for a full year.
AMINA holds the tokens in its own custody setup and applies full KYC/AML checks, framing the service within a clear compliance process for institutional onboarding and ongoing monitoring.
Institutional implications and regulatory context for AMINA
The documentation highlights core risks, including slashing risk at the protocol level, price swings in the market, and a fixed lock-up period that constrains immediate access to funds.
Polygon appears as a strategic partner in the release, with the choice justified by the network’s low fees, fast settlement and high stablecoin activity, aligning with throughput and cost considerations for institutional staking.
Staking is defined as locking tokens to support a Proof-of-Stake chain in exchange for rewards proportional to the size of the stake, which in this case ties institutional participation directly to the security of the Polygon network.
The announcement sets out four concrete points for institutional users that frame how adoption, returns, liquidity and regulation intersect in this offering. The release marks the first time a regulated bank offers POL staking to institutions, and the service is live and available to clients that pass AMINA’s onboarding checks.
In practical terms, institutions now have a supervised path to stake POL within a clear regulatory frame, balancing potential yield against lock-up and protocol risks while contributing to Polygon’s network security.
