The Cardano Developer Portal

Cardano Developer Portal

We wanted to build a developer portal as open and inclusive as Cardano. A portal that is in the hands of the Cardano community and can be constantly evolved by it.

For this to be successful, the portal relies on your contributions, and the fact that you are reading this text probably means that you have something to contribute, even if you are not a Developer.

Please find a detailed installation guide on developers.cardano.org/docs/portal-contribute/.

Requirements:

Node.js version >= 16.14 Yarn version >= 1.5
On macOS you also need Xcode and Command Line Tools.

Clone the repo

git clone https://github.com/cardano-foundation/developer-portal.git

Navigate into the folder

cd developer-portal

Install all dependencies

yarn install

Production build

Create at least once a production build (as this pulls missing files)

yarn build

Local development

yarn start

This command starts a local development server and open up a browser window. Most changes are reflected live without having to restart the server.

Project structure

Please find the project structure and more detailed information on developers.cardano.org/docs/portal-contribute/.

nodejs and yarn version

Hi all,
thank you for inviting me to participate here. In following the readme.md I have encountered issues with both nodejs and yarn versions (minimum 12.13 and 1.5, respectively). I am running this in ubuntu 20.04 and I am able to get nodejs 10.19.0 and yarn 1.22.5.

This in turn results in the following error when running yarn install:
yarn install v1.22.5 [1/4] Resolving packages... [2/4] Fetching packages... info [email protected]: The platform "linux" is incompatible with this module. info "[email protected]" is an optional dependency and failed compatibility check. Excluding it from installation. info [email protected]: The platform "linux" is incompatible with this module. info "[email protected]" is an optional dependency and failed compatibility check. Excluding it from installation. error @docusaurus/[email protected]: The engine "node" is incompatible with this module. Expected version ">=12.13.0". Got "10.19.0" error Found incompatible module. info Visit https://yarnpkg.com/en/docs/cli/install for documentation about this command.

The yarn start and yarn build commands therefore both result in a "docusaurus: not found" error.

Any suggestions?

Stef

Missing ADA's in transfer !

Hi all,

I have transferred 500+ ADA from my Nami wallet to my Binance account, it has been 7 hours already and the funds haven't shown up, even though the transaction went through normally and the ADA's left the wallet immediately.

Please help!

Broken link at "how to register your stake pool metadata"

Steps to reproduce:

1. Open section Register Stake Pool Metadata
   
2. Find the link to "how to register your stake pool metadata", click it
3. See

Take a look at the Plutus Tutorial link is not working.

https://developers.cardano.org/docs/smart-contracts/plutus

The link found on this paragraph does not work

Take a look at the Plutus Tutorial if you want to learn Plutus from the beginning. If you don't know Haskell yet, consider starting with Haskell.

Requirement to sort the builder tool array

We should get rid of the requirement to sort the builder tools array alphabetically when adding entries. Just adding at the end is fine as it is sorted automatically these days.

Remove "Legacy key" part from Handbook

I propose to remove "Legacy key" part from Operate a Stake Pool - Handbook. Do we still need it there?

I found that on 3 pages. 2 of them are in Handbook, so I'm pretty sure nobody needs legacy keys at least for creating a pool. No? If this is ok, I will create PR.

CIP-0020 choice of format/structure - suggestion

I have a suggestion for what, in my view, would be an improvement to the current proposed structure of the 674 message.

I couldn't find any discussion platform for this topic so I felt like creating an issue was the only way I could bring this to people's attention.

{ 
  "674":
          { "Invoice-No": "1234567890",
            "Customer-No": "555-1234",
            "Comments": ["P.S.: i will shop again at your store :-)"
                                , "Shopping experience was excellent"]
         }
}

In my opinion, storing key/value pairs inside a string, inside an array, inside a JSON metadata structure is not a smart approach. JSON is already a key value data format. Storing key/value data in this way will introduce the need to have to implement a custom parser, whilst preserving a JSON structure gives easy access to these values directly.

Metadata is expected to be provided as JSON. It is even stored in a column called json in the tx_metadata table in the db-sync database.

Existing tools/wallets already display 721 data in a structured way, by iterating over the key/value pairs,and showing them as labels and values respectively.

The current 674 proposal will introduce the need to handle 674 metadata in a different, inconsistent way.

I also believe that the "msg" key is redundant and offers no extra benefit. The 674 key is already enough to identify the metadata type.

The 674 content structure will be determined by the creator of the transaction/tool and will therefore not follow any particular common standard. Having reserved keys such as "version" etc could be left entirely at the discretion of the transaction creator.

I therefore do not see the added value of having a reserved top-level for keys such as msg, ver, etc...

listening-for-payments-cli doesn't explain how to distinguish customers

@katomm I read your https://developers.cardano.org/docs/integrate-cardano/listening-for-payments-cli but there is major issue in that flow - you can't distinguish between individual customers in that model, you can only track what is current balance of that one address. This would work if you only ever had 1 customer.

How would the proper flow look? Each customer has dedicated address? If yes, then how would you generate a secondary address for the same wallet? And how would you send ADA out of it using cardano-cli? I was experimenting with that but ultimately failed every time - https://forum.cardano.org/t/how-to-properly-sign-transaction-from-non-base-address/74462

It would be of great help if that page could be expanded to cover a fully functional model instead of this trivial example that assumes only 1 customer ever. Thanks!

"Build with Transaction Metadata" - topic suggestions

Please reply here if you have a topic suggestion for the "Build with Transaction Metadata" category. (unless the suggestion is worth opening its own issue)

Incorrect link on Catalyst page

On this page:
https://developers.cardano.org/docs/fund-your-project/project-catalyst
Bottom section : FAQ
Top Link: Participation FAQ
This link leads to a generic page about Ideascale, which also shows how to VOTE inside Ideascale. This will lead folks astray.

I do not see any need to utilize this link, since we have two other FAQ listed there in that section which cover the need.

Use consistent paths in code samples (accross all guides)

It would make sense to agree on a consistent environment across guides

From what I've seen so far, it's pretty consistent but not everywhere... I find that I have to switch directory structure between different guides and my files started ending up everywhere...

I would suggest the following setup

/home/user/cardano
|_ /keys # from cardano-cli guides
|_ /wallets # from cardano-wallet guides
|_ /db
|_ /integrate-cardano-samples
  |_ /id-of-guide-1
    |_ draft.tx
    |_ draft.signed
  |_ /id-of-guide-2
  |_ ...
|_ /build-tx-metadata-samples
  |_ /id-of-guide-1
  |_ /id-of-guide-2
  |_ ...

This setup would allow all guides to first ask the user to check that he is in the correct directory (and let him cd into it)

$ pwd
/home/user/cardano/integrate-cardano-samples

and then for cardano-cli commands "reach up" for .skeys or protocol.json

$ cardano-cli query utxo \
--testnet-magic 1097911063 \
--address $(cat ../keys/payment1.addr)

cardano-cli transaction sign \
--tx-body-file tx.draft \
--signing-key-file ../keys/payment1.skey \
--testnet-magic 1097911063 \
--out-file tx.signed

SPO Sidebar navigation

I am updating the SPO part and will do it in several small steps. The first topic is:

• to reorganize the Stake Pool section and integrate the content in the handbook into the course. The new sections could be

1. Introduction
2. Pre-requisites
3. Installing & Configuring Cardano Nodes
4. Registering a Pool
5. Pool Maintenance
6. Tools and Links

Please add NFT vending machine python scripts

Update build instructions for node 1.35.0

Details here, at the very minimum :

• Update system requirements
• include lib256k1 build instructions
• Add notes about Op Cert counter increment being 1 (as compared to last block on chain from same pool, 0 otherwise)
• CLI Updates (Formatting, kes-period-info, leaderlogs, ...)

Change user in node setup to relative $USER

Adding the relative $USER to the paths we can just copy paste the commands from the documentation to our console to set-up a node.

Broken link / missing Grafana guide in lesson-5.md

docs/stake-pool-course/lesson-5.md links to https://docs.cardano.org/projects/cardano-node/en/latest/logging-monitoring/grafana.html but it seems this was removed.

My suggestion is to add a new Grafana guide directly in the portal.

remove obsolete `--mary-era` option in faucet article

Following the guide at Explore Cardano Wallet I get the following error when querying wallets for UTxOs

cardano-cli query utxo --mary-era --testnet-magic 1097911063 --address $(cat ~/cardano/keys/payment1.addr)

Invalid option `--mary-era'
Usage: cardano-cli query utxo [--shelley-mode | --byron-mode

                                --cardano-mode [--epoch-slots NATURAL]] 
                              (--whole-utxo | (--address ADDRESS) | 
                                (--tx-in TX-IN)) 
                              (--mainnet | --testnet-magic NATURAL) 
                              [--out-file FILE]
  Get a portion of the current UTxO: by tx in, by address or the whole.

Works fine without the --mary-era option.

Add structure to `Integrate Cardano`

Improve Structure for "Integrating Cardano" section

The structure of Integrate Cardano should be improved. Below ere are the issues I found. I aggregate them all here as to not spam the Issues Tab with my own issues. You can create new issues and assign them to me if you like, I'll do them whenever I have some time to spare.

I am not sure how much thought went into this section and I apologize if I miss the advantages of the current structure

Sub issues

No content in Overview

IMHO the integrate-cardano/Overview.md needs to talk about what this section is about.

• It should inform the reader about the necessary articles that he should read before continuing.
• It should introduce and motivate the guides it contains.
• It should briefly talk about the term integration and explain how the guides try to help achieve integration.
• It should mention that the guides provide low-level solutions in different languages. Readers should be encouraged to submit an issue for "missing" languages.
• It should introduce the components covered in the guides (cardano-node, cardano-cli and cardano-wallet) and present the structure of the following guides.

Inconsistent Headings

• fix header levels

The used headings in the articles creating-wallet-faucet.md, listening-for-payments-cli.md and listening-for-payments-wallet.md begin on level 3 instead of level 2 breaking md001

The above structure will also improve the side-bar in the guide to contain subchapters and allow to jump to topics like creating a wallet with cardano-cli.

• Dont use Emphasis as Headings

Throughout the article (f.e. in ### Create simple transaction paragraphs) we use Emphasis (**Generate recovery phrase**) instead of Heading (#### Generate recovery phrase) breaking md036

Long articles

creating-wallet-faucet.md is a very long article and talks about the following topics:

• Overview
• Carano wallets
• Creating a wallet
  • Creating a wallet with cardano-cli
    • Querying the wallet UTXO with cardano-cli
    • Creating simple transaction
      • generate payment key-pair for wallet 1
      • generate wallet address for wallet 1
      • query UTxOs for wallet 1
      • requesting funds from Testnet Faucet
      • generate payment key-pair for wallet 2
      • generate wallet address for wallet 2
      • query wallet UTxOs for wallet 2
      • query protocol parameters
      • Create draft transaction
      • Calculate min fee
      • Create draft transaction
      • Sign transaction
      • Submit transaction
  • Creating a wallet with cardano-wallet
    • Starting cardano-wallet as a REST API Server
    • Checking wallet server information
    • Creating the wallet via API
    • Receiving tADA (Test ADA)
    • Creating simple transaction
      • generate recovery phrase
      • recovery phrase result
      • create wallet request
      • create wallet result

The following subissues could help improve readability.

• move Creating simple transaction one layer up and rename to Creating simple transaction with cardano-cli and Creating simple transaction with cardano-wallet respectively
• Split fauctet article into multiple guides / use cases (like "Creating a wallet", "Receiving tADA", "Building a transaction", "Receiving payments").

Testnet Faucet Limit

If one works through the entire article he will first submit 1000 ada to the wallet he created using cardano-cli. Then (20 minutes later) he will create a new wallet using cardano-wallet and again request 1000 ada from the faucet which has a payout limit for 1000 ada / day.

• mention this limit explicitly to make the reader aware of the consequences if he works throught the entire article.
• reduce the guide's requested Ada to 500 ada for both paths (cardano-cli and cardano-wallet).
• insert / create a new guide that submits a multi-wittness transactions to transmit funds from wallet 1 and 2 to wallet 3.

Oddball solution

We have the focus on two components: cardano-cli and cardano-wallet. We try to give the reader an idea on how to integrate them.

We use two approaches to present this information to him. theme-based approach and component-based approach

• Adopt Theme-based structure (as in creating-wallet-faucet.md)
• Adopt Component-based structure (as in listening-for-payments-cli.md and listening-for-payments-wallet.md)

I think I like Component-based more because the articles are shorter, but I really don't know what is better.

Don't repeat yourself

The guides contain some repetition. Sometimes this is unavoidable when talking about two components who do very similar things. The improvements should help avoid the unneccesary repetitions.

• reduce repetition by improving structure

As an example, we have this paragraph from the cardano-wallet-faucet.md

As mentioned before, in this guide we will only be focusing on the cardano-cli and cardano-wallet since they provide some level of programmability which is important when we are talking about Cardano integrations for different kinds of use-cases.

This could be moved to the overview.md and not be talked about anymore. By removing this paragraph we could move all headings one layer up which would improve the structure of document further.

Typos

• #181

Improve current structure (draft)

Until we settle on the approach of the guide (theme-based or component-based or both or leave it as is) I'll leave this here as a draft and "mind map"

SPO course, security review needed

The content currently in the stake pool course needs a security review on best practices when it comes to key-related things.

We should not write content like "in the testnet, you can do it like this" - no, stake pool operators should learn how to do things the right away from the beginning.

Please also see this related issue: #43

Non Github accounts

Hello everybody!

We're a family owned company called Bakrypt.io that is building technology on top of the Cardano Blockchain. We offer minting services, IPFS and cloud storage for anybody who wants to create native tokens or collections up to 300 assets per request on the Cardano blockchain. We have a mainnet and testnet environment. We also offer white label services for resellers who would like to integrate these services into their website.

What are the steps required to include our project within the developer portal? I'm attaching links for referral.

Grafana Loki for SPOs page in Handbook

Hi!

I recently created documentation how to use Loki as centralized logging solution for SPOs:

https://forum.cardano.org/t/grafana-loki-as-centralized-log-solutions-for-pool-operators/100824

I propose to create page with same information under Handbook, I think it will be quite nice addition.

More advanced payment integration

I understand this is all new and still very early but I'm wondering if more advanced payment integration is possible. I went through the example of accepting payments, but I have an app releasing soon where I charge the customer through credit card only after my service takes place.

1. I'm able to place a hold on their credit card for x amount and then their order is sent to my server if there's enough funds.
2. After service is done, I replace the hold on their credit card with variables on what happened during the service(ex: An Uber driver driving 8 miles is going to charge the customer less than driving 20 miles).

Am I able to replicate this kind of flow with Cardano? I'm a holder and was hoping this flow was possible with the blockchain. Again, I understand this is still early but I would love to have Cardano integrated with my app if possible. Thanks.

Top level menu

The Top Level Menu in my perspective does not match to the sidebar menu. One simple solution would be to remove "Testnets" which is subtopic of "Get Started" and place "Get Started" on the top menu instead. So, the user would have the option of navigating to one of the main topics from top menu or to one of the sub-topics from the boxes on page. What do you think?

Burning tokens via cardano-wallet-js?

I can see they provide an example on how to mint and send minted native tokens (this works without any issues), however I am interested is it possible to burn native tokens via this library?

I was testing the running cardano-node section using the prebuilt binaries build 6907168 and noticed the testnet-alonzo-genesis.json is missing from the list of configuration files here

I will finish the tutorial on the website, fix the issues I see and submit a PR later

SPO course, security chapter missing

The stake pool course needs a security chapter (better the topic should run through the whole course, but you have to start somewhere). We can use this issue to discuss ideas, requirements or any thoughts.

If anyone found their way here because they thought they were getting safety tips for their stake pool, please read on here: https://forum.cardano.org/c/staking-delegation/stake-pool-security/157

The security chapter should make clear that you must not have any payment key on the server. Also: how to handle keys in a secure way.

It would also be interesting to mention what people can do if there is more than one operator. Maybe one wants to share the stake key.
How to create, handle and sign transactions on an air-gapped machine.
Probably interesting also the scripts and how-tos that Martin did: https://forum.cardano.org/t/new-ledger-trezor-update-for-owner-pledge-stakepool-operator-scripts/43953

In general, the https://forum.cardano.org/c/staking-delegation/stake-pool-security/157 is full of great posts around this topic and I'm sure other people have even better ideas what to put in.
