Smart Contract Development & Audit in Seoul

Reentrancy and logic vulnerabilities

Unaudited contracts are a common attack vector; a single flaw can lead to irreversible loss of funds.

High gas costs eroding user experience

Inefficient contract logic makes transactions expensive and discourages adoption.

Upgrade and governance risk

Poorly designed upgrade patterns create centralization risk or lock teams out of fixing bugs post-launch.

Missing audit trail before funding or listing

Exchanges, investors, and launchpads require a clean audit report before they will list or fund a token.

Integer overflow and precision errors

Fixed-point arithmetic mistakes in fee calculations or reward distributions silently misallocate funds long before anyone notices the discrepancy.

Untested edge cases in access control

Role-based permission systems that work in the happy path often have gaps that let an unintended caller trigger a privileged function.
