According to CoinMeta, Starknet indicates that its account abstraction feature supports the replacement of verification logic without changing the address, balance, or historical records, thereby enabling post-quantum migration without the need for a hard fork. As a Layer 2 solution for Ethereum, Starknet still relies on Ethereum and elliptic curve cryptography for settlement, data publication, and cross-chain bridging. Currently, in the independent research phase of L1, one can set their own cryptographic scheme and migration timeline. STRK remains a native token, with no plans to issue a new token at this time; migrating to L1 requires a governance vote.
