Is it safe to deploy a 8,000,000 gas contract

contract-deploymentgas-limit

8,000,000 gas seems to be the maximum gas allowed when deploying a contract on mainnet.

My question is, is it even safe to do so or do I have a bigger risk that my deployment tx fails ? If so I would loose my consumed gas at every failed attempt.

Do I need to take a margin ? (say 7,500,000 ??)
Do I need to put high gas price to be sure to be included in next block in priority?
I see the latest blocks with 30,000,000 gas limit, so does the 8,000,000 limit only applies to deploying contracts ? (if so 8,000,000 should be safe !)

If the transaction is under the current Ethereum consensus rules it should be allowed.

But miners have the final decision some might prefer to exclude large transactions unless the gasPrice is above average, other probably won't care.

You can start sending it with above average gasPrice and then increasing it by 10 percentage until it is mined or the cost is too much.

Here's a tutorial and general approach:

https://dappsforbeginners.wordpress.com/tutorials/interactions-between-contracts/

You split the contract into several contracts, and you can create references to "parent" contracts, such as:

contract referencedContract {   
  function fn() {}
}

contract referencingContract{

  // create reference to contract
  referencedContract m = referencedContract(referencedContractAddress);

  // call referenced contract method
  m.fn();
}

[Ethereum] Recommended Gas Limit for Single Transaction

The gas limit should be as high as your transaction will consume, and no higher. The amount of gas a transaction consumes depends on what it does. (Bear in mind that if your transaction results in gas refunds, for example because it deletes storage data, you still need to account for it in the gas you supply.)

Most miners will fill blocks up to the limit, and it's OK to set a limit that takes close to or all the gas available in a block, but since miners take transactions with higher fees first, this will increase the gas level you will need to set to outbid other transactions that could fit in the block. So you will need to compensate for the higher gas limit by setting a higher gas price. See https://ethgasstation.info/ for specific data on how high a gas price you are likely to need for any given gas limit.

If you're just doing a simple send, just use 21,000.
