Ethereum Batch Deposit Contract

Our contract facilitates the pooling of multiple ETH deposits for submission to the Ethereum beacon chain in a single transaction. This method is not only convenient but also maximises gas efficiency, reducing overall costs.

🚧
Avoid EVM gas limits
Due to EVM constraints relating to large amounts of loop iterations, it is recommended to deposit in batches of up to 500 at a time.
If you encounter issues with failing transactions, try a smaller batch.
