What steps should be taken to ensure the security of smart contracts in a cryptocurrency project?

[auroragrace]

To secure smart contracts, start with rigorous code audits and peer reviews. Employ a secure programming language, like Solidity, and adhere to best practices in coding. Implement automated testing to catch vulnerabilities early. Consider using formal verification methods to mathematically prove contract correctness. Restrict access to sensitive functions and ensure robust authorization protocols. Utilize multi-signature wallets for added security. Finally, stay updated with the latest security trends and vulnerabilities to protect against emerging threats.
