In line with OpenSSL's recommendation to use a more modern algorithm instead of EVP_BytesToKey it is recommended that developers derive a key and IV on their own using crypto.scrypt() and to use crypto.createCipheriv() to create the Cipher object. Users should not use ciphers with counter mode (e.g. CTR, GCM, or CCM) in crypto.createCipher(). A warning is emitted when they are used in order to avoid the risk of IV reuse that causes vulnerabilities. For the case when IV is reused in GCM, see Nonce-Disrespecting Adversaries for details.

As the Ethereum network has become costlier to use, the bull seasons native chain gained a lot of traction for the same functionalities. At one point it was processing 4 times the transaction of the Ethereum network. Essentially, smaller transactions in comparison to larger investments are extremely difficult to send from wallet to wallet.
