Ethereum Ropsten testnet account nonce - same address on mainnet - initially I thought it is a bug...
At some in the past I suggested "test drive" ICO - deployed to the testnet - soon I've realised it would cause a lot of drama - sending real ETH to an address on another network.
So I did some research:
- https://ethereum.stackexchange.com/questions/10677/is-it-possible-and-sensible-to-deploy-a-contract-to-the-same-address-on-mainnet
- https://ethereum.stackexchange.com/questions/27432/what-is-nonce-in-ethereum-how-does-it-prevent-double-spending
Today without realising what I'm doing, I accidentally did it, and then recalled why it was possible.

(initially I thought it is a bug)
Fresh account deploying the same contract and the address matches! Note that Gnosis multisig is really nice, highly recommending for anything more serious than random 0.1 ETH thrown at some ICO:
