One of the biggest concerns when using EVMs is vulnerability to cyberattacks. Since most EVM blockchains use the Solidity programming language, if an attacker finds vulnerabilities in Solidity, they can exploit them to attack multiple blockchains at the same time. For example, a cross-chain attack on Poly Network in August 2021 caused hundreds of millions of dollars in losses and affected various ecosystems. Audits are costlyTo ensure security and reliability, smart contracts on the blockchain need to go through a professional audit process. However, the audit cost of smart contracts on the EVM blockchain is often very expensive, ranging from $7,500 to $100,000 depending on the size and complexity of the project. For projects that wish to give birth to multiple EVM blockchains, the cost of auditing will increase dramatically, becoming a heavy financial burden. Another problem with high transaction fees for EVM blockchains is the high transaction fees, especially when the network is congested. For example, on Ethereum, transaction fees can reach $7 to $10 when the network is less active, rising even more at peak times. Even on newer EVM blockchains like Avalanche or Starknet, transaction fees still hover around $1 to $2. In contrast, transaction fees for blockchains that don't use EVM (e.g., Solana, Sui, Aptos, etc.) are typically $0.01 to $1, which is much lower than EVM blockchains.
