This standard mainly achieves security through the combination of the SHA-256 hashing algorithm and ECDSA (Elliptic Curve Digital Signature Algorithm). Specifically, the IERC20 standard requires issuers to implement corresponding signature functions when creating token contracts, enabling signature verification for token issuance, transfer operations, and more. Through this mechanism, the security of ERC20 tokens during the trading process is ensured."}]}],"pr":"84340a0e2b95b5e914f8b16e99e0dcca34501bd0696f7a9e62e51528f3c9f752"}
