- South Carolina Governor Henry McMaster has signed S.163 into law, giving cryptocurrency users and businesses stronger legal protections.
- The law protects digital asset payments, self-custody through hard wallets, and prohibits additional state or local taxes on cryptocurrencies used for payments.
South Carolina has moved into the pro-crypto column. Gov. Henry McMaster signed S.163 into law on Tuesday, changing the state’s legal code to give individuals and businesses clearer protections when using digital assets.
Cryptocurrency payments and self-custody are legally protected
New law He says Individuals and businesses may not be prohibited from accepting digital assets as payment for goods and services. This wording is important. It simply does not tolerate cryptocurrencies on the sidelines. It gives merchants and users a stronger legal basis to treat digital assets as a valid payment option within the state.
The bill also protects the use of self-hosted wallets and self-custodial hard wallets. In practice, South Carolina residents cannot be prevented from holding their private digital assets outside of a centralized platform. This is one of the most sensitive issues in the crypto policy debate.
After stock exchange failures, frozen accounts, and enforcement disputes, self-custody has become more than just a technical preference. For many users, this is the fundamental promise of cryptocurrencies.
For businesses, the law provides a more predictable environment at the state level. Trader who wants to accept Bitcoin, stablecoins Or other digital assets now have clearer guarantees that the payment method itself cannot be blocked simply by state policy.
This doesn’t remove the harder parts. Federal tax rules still apply. Compliance with sanctions remains important. Money transfer questions don’t go away. Businesses that accept cryptocurrencies still have to manage accounting, fluctuations, refunds, and conversion into dollars. But the law narrows down one important risk: additional resistance at the state level to the core business of accepting or holding digital assets.
The anti-ECB stance adds political heft
S.163 also fits into broader political pressure against central bank digital currencies. Many US states have introduced similar measures, and often do so Central bank digital currencies As a potential threat to financial privacy, private sector payments and individual control of funds.
South Carolina law focuses on the use of private digital assets rather than launching a government crypto program. It also exempts cryptocurrencies used for payment from any additional tax, withholding, assessment, or fees imposed by state or local governments.
This part is not just symbolic. Without them, cryptocurrency payments could be legal in theory but unattractive in practice, if users face additional state or local costs simply for choosing a digital asset instead of a card or bank transfer.
This action does not make cryptocurrencies legal tender. It also does not force companies to accept digital assets. The store can still select payment methods that are appropriate for its own operations. What the law does is prevent the state from placing cryptocurrency payments and self-custody in a category that is too restrictive.
Timing is also important. Cryptocurrency policy in the United States has become increasingly fragmented, with federal agencies, Congress, and state legislatures moving at different speeds. South Carolina is now signaling that, at the state level at least, it wants to protect the basic use of cryptocurrencies before broader national rules are fully settled.
