A sweeping new law regulating digital assets and cryptocurrency activity took effect in South Carolina on May 19, after being signed by Governor Henry McMaster. The law provides numerous legal protections for individuals and companies involved in crypto transactions and mining. First proposed at the start of 2024, the bill passed the state senate by a vote of 38 to 1, though legislative differences slowed its progress for nearly a year. The final version was officially enacted following a series of amendments.
CBDC limits and restrictions on government role
Under the new legislation, state agencies in South Carolina are now barred from accepting central bank digital currencies (CBDCs) as payment. Furthermore, state employees are prohibited from participating in federal programs that involve digital dollar pilots initiated by the Federal Reserve or other federal entities.
The law clearly defines CBDCs as digital currencies issued directly by the US central bank or other federal authorities, while stablecoins launched by private companies and backed by the US dollar or government debt are excluded from these restrictions.
Glossary: A CBDC (Central Bank Digital Currency) is a form of electronic money issued directly by a central bank or government, representing the national fiat currency in digital form. CBDCs are typically designed to increase financial system efficiency by digitizing payments and reducing intermediaries.
While this rule blocks the use of federal digital currencies like a US CBDC in South Carolina, it leaves the door open for the use of privately issued stablecoins such as USDC.
Legal rights for wallets and safeguards for miners
The law also enables individuals and businesses to legally accept digital assets as means of payment for goods and services. It guarantees the use of all types of digital wallets—including personal and hardware-based wallets—while also preventing state and local governments from imposing additional taxes on those transacting in digital assets.
Crypto mining companies operating in industrial areas now enjoy explicit legal protection. Local authorities are no longer permitted to impose targeted noise restrictions or discriminatory regulations on mining operations.
The legislation specifies that activities such as operating blockchain nodes, crypto mining, developing new blockchain software, and providing staking services are, under certain conditions, exempt from money transmitter licensing requirements.
It also clarifies that companies providing crypto mining or staking services will not be classified as broker-dealers under South Carolina securities law solely by virtue of their activities. However, the state attorney general retains the right to take action against firms providing misleading information to customers.
Energy requirements and state-by-state trends
According to the new rules, large-scale mining operations may not place undue strain on the power grid. Mining firms must present energy supply contracts to state authorities showing their capacity to reduce electricity usage if necessary.
| State | Crypto Mining Protection | CBDC Ban |
|---|---|---|
| South Carolina | Yes | Yes |
| Oklahoma | Yes | Yes |
| Florida | Yes | Yes |
| Arizona | Yes | Yes |
Alongside South Carolina, Oklahoma, Kentucky, Arkansas, Florida, Mississippi, Montana, North Dakota, Louisiana, and Arizona have all enacted similar laws between 2024 and 2026. The non-profit Satoshi Action Fund has played an influential advocacy role during this legislative wave, promoting miners’ rights and personal wallet ownership across the US.
National CBDC ban effort faces roadblocks
On the federal level, a CBDC ban—slated to last until 2030—was added by the Senate in March to the 21st Century ROAD to Housing Act, a major housing bill. The provision would prevent the US central bank or any intermediary from launching a CBDC nationwide.
US legislators emphasized, “Financial privacy is a cornerstone of American liberty; any decision to authorize a Central Bank Digital Currency must rest directly with Congress and the American people.”
The fate of this national law remains uncertain, as the House of Representatives has so far rejected the proposed homeownership caps in the bill. Former President Donald Trump’s statement that he would not sign laws lacking requirements for voter identification and citizenship in the 2024 mid-term elections has added further uncertainty over the law’s prospects.
