South Carolina’s governor has signed S.163 into law, establishing new protections for Bitcoin self-custody in the state. The bill, which moved through the South Carolina legislature during the 2025-2026 session, marks a concrete step in state-level policy toward recognizing the right of individuals to hold their own digital assets.
What happened with South Carolina’s S.163 bill
The signing of S.163 converts the measure from a legislative proposal into enforceable state law. The bill is specifically framed around Bitcoin self-custody, the practice of individuals holding their own private keys rather than relying on third-party custodians such as exchanges or banks.
The bill’s legislative text was introduced in the South Carolina Senate during the current session. Its progression through both chambers and arrival on the governor’s desk followed standard legislative procedure tracked through the state’s official bill records.
Why Bitcoin self-custody is the central issue
Self-custody is a foundational concept in Bitcoin. It means a user controls the cryptographic keys that authorize transactions from their wallet, removing dependence on intermediaries. When an exchange fails or freezes withdrawals, self-custody users retain access to their funds.
The distinction matters because regulatory uncertainty has left Bitcoin holders unsure whether future rules could restrict personal custody. A state law explicitly protecting this right removes ambiguity for residents and businesses operating within South Carolina.
South Carolina’s approach focuses narrowly on custody rights rather than broad market regulation. That sets it apart from the federal debates around Bitcoin ETF filings and from the kind of prediction market expansions that occupy other corners of the digital asset policy landscape.
What the South Carolina law could signal next
A governor’s signature transforms a proposal into precedent. Other state legislatures tracking Bitcoin policy may view South Carolina’s action as a template, particularly those weighing similar self-custody or digital asset protection bills.
The law’s narrow focus on self-custody, rather than attempting to regulate exchanges, stablecoins, or DeFi protocols, may make it easier to replicate. States looking to signal openness to Bitcoin holders and businesses can adopt a similar targeted approach without wading into more contentious regulatory territory.
As recent survey data shows growing crypto adoption among U.S. adults, the policy question of who controls digital assets, the individual or an intermediary, is becoming harder for lawmakers to ignore. South Carolina’s S.163 is now law, and Bitcoin self-custody has gained explicit state-level legal protection.
