When launching new Ethereum validators, using the batched transactions with the Staking API saves time and gas compared to the official deposit contract.

👍
Note
You can save over 50% on gas usage when launching 250 validators with Blockdaemon.

Recommended Gas Limits

The Post Stake Intent endpoint allows you to stake to 250 validators using our audited batch deposit contract.

We recommend you use the following gas limits when staking ETH with the Staking API:

# of validators to launch via Blockdaemon API	Recommended setting for gas limit (in GWEI)
1	100,000
2	200,000
5	300,000
10	400,000
25	900,000
50	1,700,000
100	3,300,000
150	4,800,000
200	6,300,000
250	7,900,000

Info

Recommended gas limit contains buffer and is rounded up for convenience; you only pay for actual gas used.

gas used varies slightly due to different parameters at execution time, and the USD price to launch validators depends on the gas price and ETH/USD value.
