South Carolina Governor Henry McMaster has signed one of the most comprehensive cryptocurrency rights bills in the United States. The legislation, S.163, grants residents the legal right to use digital assets for payments, self-custody wallets, and mining operations, while barring state agencies from participating in central bank digital currency (CBDC) testing programs.
The bill creates a broad state-level crypto framework designed to support adoption while limiting government control over crypto-related activities.
Self-Custody and Digital Payments Secured Under Law
Under the new rules, businesses and individuals can freely accept digital assets as payment for goods and services. Residents maintain the legal right to store cryptocurrencies using self-hosted or hardware wallets without interference from state authorities. State and local governments cannot impose additional taxes, assessments, or charges on digital asset transactions, a provision that could encourage wider merchant adoption of blockchain payment systems.
Legal Definitions and Licensing Exemptions Set Clear Rules
The legislation adds formal definitions for blockchain, staking, nodes, wallets, digital assets, and crypto mining into state law. Several blockchain activities gain exemptions from money transmitter licensing requirements, including crypto-to-crypto trading, mining operations, node activities, and blockchain application development. These exemptions lower compliance costs and may attract more crypto businesses to the state.
Mining Operations Get Zoning and Noise Relief
Cryptocurrency mining companies operating in industrial zones receive special protections. Local governments cannot impose mining-specific zoning restrictions or enforce noise limitations beyond general regulations. Mining firms now face fewer operational barriers when expanding facilities within the state.
CBDC Shut Out Across State Agencies
Another key section of the law targets central bank digital currencies directly. State agencies, commissions, boards, and departments cannot accept or require CBDC payments. The legislation also prevents government entities from participating in Federal Reserve testing programs involving digital currencies or similar financial systems. South Carolina joins a growing trend: earlier this year, Kentucky passed similar protections for self-custody and mining. The new law positions South Carolina among the most crypto-friendly jurisdictions in the country.
