Key Takeaways

EIP-7983 sets a 16.77 million gas limit per transaction to stop single calls from blocking the network;
The cap aims to improve stability, prevent overload attacks, and keep transaction costs steady;
Most transactions already use less gas, so regular users and developers won’t be heavily impacted.

Vitalik Buterin and Toni Wahrstätter have introduced EIP-7983, a proposal to set a clear gas limit for single transactions on Ethereum ETH $2,549.22 .

Currently, a single transaction can consume all the gas available in a block. This creates a risk where someone could overload the network and disrupt normal operations.

EIP-7983 addresses this by capping the gas for a single transaction at 16.77 million gas units. Any transaction asking for more would be rejected before it is added to a block.

The goal is to spread gas use more evenly so that no single transaction can take over the entire block. This is expected to make the network more reliable, reduce the risk of denial-of-service attacks, and keep transaction costs more predictable.

The cap would not change the overall block gas limit, which miners and validators can still adjust as usual.

The number 16.77 million was chosen because it supports current needs, such as deploying smart contracts and running complex decentralized finance (DeFi) applications. It also works well with zero-knowledge virtual machines, which perform better when large transactions are broken into smaller ones.

According to the draft, transactions over the limit would be rejected during block validation and never reach the wider network. The limit applies only to individual transactions, so the total gas per block remains flexible.

Most existing transactions already use much less gas than the proposed cap. Therefore, regular users and developers are unlikely to be affected. Only large, complex operations would need to adjust their design slightly to fit within the limit.
