South Carolina Cryptocurrency Rights Law
South Carolina Governor Henry McMaster signed S.163 into law on May 20, making South Carolina one of a small group of U.S. states to formally protect the rights of cryptocurrency holders in statute. The law bars state agencies from accepting or using a Federal Reserve central bank digital currency, while explicitly protecting residents’ rights to self-custody digital assets, operate mining equipment, run network nodes, and earn staking rewards.
The legislation applies immediately to all state government entities.
What S.163 Actually Does
The bill covers four distinct protections for cryptocurrency users in South Carolina. First, it prohibits state agencies from using a CBDC issued by the Federal Reserve as legal tender or as a payment method in any official transaction.
Second, it affirms that residents may hold private keys to their own digital assets without state interference, a direct endorsement of self-custody. Third, it protects the right to mine cryptocurrency using personal hardware, shielding home and commercial miners from local ordinance overreach.
Fourth, it protects staking, the process by which holders lock up tokens to help validate transactions on a proof-of-stake blockchain and earn rewards in return. Node operation, the act of running software that verifies and relays blockchain transactions, is also explicitly protected under the new statute.
Self-custody refers to holding digital assets in a wallet where the owner controls the private key, rather than leaving tokens on an exchange where a third party holds that key.
The distinction matters legally because custody arrangements can affect whether a holder is treated as a financial counterparty under certain regulatory frameworks.

Background
South Carolina’s bill follows a broader wave of state-level cryptocurrency legislation that accelerated through 2025 and into 2026. Several states, including Arizona, Montana, and Wyoming, passed or introduced legislation addressing digital asset custody, mining rights, or CBDC restrictions during that period.
Wyoming’s early framework, enacted years prior, gave legal standing to digital assets as property and inspired subsequent state efforts. The South Carolina measure reflects that pattern, adopting a rights-affirmation structure rather than a regulatory licensing framework.
The CBDC restriction in S.163 mirrors language seen in legislation passed in other Republican-led states, where opposition to a potential Federal Reserve digital currency has become a recurring policy theme. A CryptoTimes report published May 20 first detailed the bill’s signing and its specific provisions.

Why the CBDC Clause Draws Attention
The prohibition on state agency use of a Federal Reserve CBDC is the clause generating the most discussion among legal observers and cryptocurrency advocates.
No Federal Reserve CBDC exists yet, making the ban preemptive. Supporters argue that early statutory limits prevent future pressure on state governments to adopt a digital dollar for tax collection, benefits distribution, or payroll.
Critics point out that a state law cannot override federal legal tender law if Congress were to designate a CBDC as legal tender, creating a potential conflict for courts to resolve later. The practical effect of the CBDC clause today is largely symbolic, though advocates treat symbolic precedents as meaningful in shaping future policy debates.
South Carolina joins more than a dozen states that have introduced or passed similar CBDC-restriction language since 2024.

What Comes Next
The law takes effect immediately, though enforcement mechanisms for the self-custody and mining protections depend on how South Carolina’s existing regulatory agencies interpret their obligations. Industry groups tracking state-level cryptocurrency legislation will likely cite S.163 as a template for similar efforts in other states later in 2026.
The bill’s mining and staking protections are more operationally immediate than the CBDC clause, since mining and staking activity exists today and local zoning disputes over mining facilities have already surfaced in several states. Whether South Carolina’s legislature returns to the topic with follow-on bills addressing digital asset taxation or exchange licensing remains an open question.
For now, S.163 establishes the state’s clearest statutory statement on what it considers protected conduct for Bitcoin (BTC) and other digital asset holders.
