Below was the original question > Hello, I found this on the onflow javascript sdk example. Is this up to date? I read on the onflow website that in order to deploy to testnet I needed to create an account on Faucet. > > [![](https://us1.discourse-cdn.com/flex022/uploads/flow/original/1X/3491fd128b4449aa28309b37ff4ea2693e21f542.png)](https://cdn.discordapp.com/attachments/621847426201944074/787740207113044000/Screen_Shot_2020-12-13_at_12.57.00_PM.png) > > When I use Blocto it doesn’t seem to connect as well > > Also, the example listed here [https://docs.onflow.org/guides/dapp-deployment/testnet-deployment/](https://docs.onflow.org/guides/dapp-deployment/testnet-deployment/) when using Testnet is with the Go SDK. Is there a Javascript example as well? Also, is there a built out example of how to deploy contracts in Javascript SDK? Thanks again ---

@Tim @Mackenzie probably can share additional info on new Testnet access documentation @JeffreyDoyle or @qvvg might be able to help with Javascript SDK examples to deploy contracts to Testnet ---

Thanks unlocked. All of my questions still stand, but my biggest concern is that last part about deploying contracts in Javascript now. When I was a part of the bootcamp during the summer it was done the same way a transaction was sent. Now it looks different because you can deploy multiple contracts to 1 account and I keep getting an error message about “setCode.” I tried looking here [Contracts | Cadence](https://docs.onflow.org/cadence/language/contracts/#deploying-updating-and-removing-contracts) but it’s too confusing for me because I can’t find a Javascript example. My end goal is really just to deploy a contract that mints test NFTs on the testnet, so whatever would help get me there is great hahahah. Thanks again 🙂 ---

Deploying contracts from JavaScript is done the same way you did it in the bootcamp, but with a small change to the Cadence code you use in the transaction itself. Previously, you would have used a transaction like this: ```auto const CODE = `transaction(code: String) { prepare(acct: AuthAccount) { acct.setCode(code.decodeHex()) } }` ``` Now that accounts have multi-contract support, your transaction should look something like this: ```auto const CODE = `transaction(code: String) { prepare(acct: AuthAccount) { acct.contracts.add( name: "Test", code: code.decodeHex(), message: "I'm a new contract in an existing account" ) } }` ``` Hi Jacob, I think the error you’re getting about `setCode` is happening because `@onflow/fcl`'s ‘stored interactions’ have not been updated with this new transaction code. You can still send the transaction without using a ‘stored interaction’ in the meantime. Multi-contract support in Cadence is a recent addition, and we’re working on bringing all the tooling up-to-date. It’s true that the documentation is lacking good JavaScript examples, at the moment. We’re also working on making a guide for JavaScript developers to follow, using the latest Cadence features! ---

Thank you! That helped me very much in deploying a Contract! Now I am trying to deploy a contract to an account using the Testnet and I can’t seem to get it to work. This link [https://docs.onflow.org/guides/dapp-deployment/testnet-deployment/#getting-started-on-testnet](https://docs.onflow.org/guides/dapp-deployment/testnet-deployment/#getting-started-on-testnet) suggests using this command using the Flow CLI: ```auto flow accounts create \ --host access.devnet.nodes.onflow.org:9000 \ --signer testnet \ --code MyContract.cdc ``` However it returns an error everytime that the code flag doesn’t exist. I tried updating the CLI and everything. I’m not quite sure what to make of this. Thanks for your help again. ---

Hi Jacob! We’ve just recently updated the CLI to support multiple contracts per account. Please update to CLI v0.12 (by reinstalling the CLI, i.e. running the installation command you used again). The `--code` flag has been replaced by the `--contract` flag, so if you have a contract `contract MyContract { ... }` in a file `MyContract.cdc`, then: `--contract MyContract:MyContract.cdc` should work.
