Is the cardano testnet consistent through time?

Hi, I am a developer and I’m considering the possibility to implement a dapp upon Cardano. Since we should already start to develop, I was thinking to start it on the on the testnet, and then switch to the mainnet when available. However, we need to keep track of a few test-transactions we will make until then so, does the testnet keep track of transactions and smartcontracts at least for a couple of months?

Also, what’s the current transaction confirmation time on the test-net and what’s the expected confirmation time on the main one?


the testnet should be out soon (a week or so maybe). it’s been done by IOHK so I’m not completely sure about times.
