Circle Bolsters Stablecoin Security Amid Quantum Computing Threats

Circle, a prominent player in the stablecoin market, has taken steps to address potential security risks associated with quantum computing. The company announced that it will be deploying its native stablecoins, USDC and EURC, along with its Cross-Chain Transfer Protocol (CCTP) and Bridge Kit tool, on the Layer 2 network, Plasma.

This move follows recent advancements in quantum computing, which have narrowed the gap to breaking ECDSA cryptographic signatures. According to a report, the theoretical threshold to break these signatures dropped from 2,330 logical qubits in 2017 to 813 logical qubits in August 2026. This development has raised concerns about the security of blockchain-based systems.

Circle's deployment on Plasma is intended to enhance the stability and security of its stablecoins. The company has also announced that it will be pausing V1 contracts of its USDC cross-chain transfer protocol on December 1, with burn limits beginning to decrease on October 1.
