South Carolina Signs Pro-Crypto, Anti-CBDC Bill Into Law

• South Carolina Governor Henry McMaster has signed S. 163 into law, giving crypto users and businesses stronger legal protections.
• The law protects digital asset payments, self-custody through hard wallets and blocks additional state or local taxes on crypto used for payments.

South Carolina has moved further into the pro-crypto column. Governor Henry McMaster signed S. 163 into law on Tuesday, changing the state’s legal code to give individuals and businesses clearer protection when using digital assets.

Crypto payments and self-custody get legal protection

The new law says individuals and businesses may not be prohibited from accepting digital assets as payment for goods and services. That wording is important. It does not simply tolerate crypto at the margins. It gives merchants and users a stronger legal basis to treat digital assets as a valid payment option inside the state.

The bill also protects the use of self-hosted wallets and hard wallets for self-custody. In practical terms, South Carolina residents cannot be barred from holding their own digital assets outside a centralized platform. That is one of the most sensitive issues in the crypto policy debate.

After exchange failures, frozen accounts and enforcement disputes, self-custody has become more than a technical preference. For many users, it is the core promise of crypto.

For businesses, the law offers a more predictable state-level environment. A merchant that wants to accept Bitcoin, stablecoins or other digital assets now has clearer assurance that the payment method itself cannot simply be blocked by state policy.

That does not remove the harder parts. Federal tax rules still apply. Sanctions compliance still matters. Money-transmission questions do not disappear. Businesses accepting crypto still have to manage accounting, volatility, refunds and conversion into dollars. But the law narrows one important risk: extra state-level resistance to the basic act of accepting or holding digital assets.

Anti-CBDC stance adds political weight

S. 163 also fits into a wider political pushback against central bank digital currencies. Several U.S. states have advanced similar measures, often presenting CBDCs as a possible threat to financial privacy, private-sector payments and individual control over money.

South Carolina’s law focuses on private digital asset use rather than launching a state crypto program. It also exempts cryptocurrencies used for payment from any additional tax, withholding, assessment or charge imposed by state or local governments.

That part is not just symbolic. Without it, crypto payments could be legal in theory but unattractive in practice, if users faced extra state or local costs simply for choosing a digital asset instead of a card or bank transfer.

The measure does not make crypto legal tender. It also does not force businesses to accept digital assets. A shop can still decide what payment methods make sense for its own operations. What the law does is prevent the state from placing crypto payments and self-custody in a more restricted category than necessary.

The timing matters as well. U.S. crypto policy is becoming increasingly fragmented, with federal agencies, Congress and state legislatures all moving at different speeds. South Carolina is now signaling that, at least at the state level, it wants to protect basic crypto use before broader national rules are fully settled.
