QUESTION
I am building an NFT smart contract with solidity, and I am trying to pass and Array of Structs into the constructor when I deploy the contract. However I am getting the following error.
...ANSWER
Answered 2022-Mar-21 at 15:36Last time I checked there was no way to pass a struct
to a constructor function
(see here this 2018 answer). It says that:
...you cannot pass struct to a constructor as it will be receiving its input outside from the blockchain. Only the private and internal functions can expect structs as input parameters.
The solution is to use "primitive" data types as inputs. For your particular case the constructor function could be modified to accept one NFT object like:

QUESTION
I have cloned this NEAR REST API SERVER repo into my local system and haven't made any changes to its original code. Only added console logs for debugging purpose. Using its API, I have successfully deployed a contract to testnet account and also called that contract.
But when comes to NFT part, its not working.
I'm calling /mint_nft
API and getting 500 Internal Server Error.
It's breaking here:
let create_token = await token.ViewNFT(tokenId, contract);
create_token is null.
If I do minting with NEAR CLI, its working fine and I can see that NFT in my testnet wallet..
near call $ID nft_mint '{"token_id": "02", "receiver_id": "'$ID'", "token_metadata": { "title": "Design #2", "description": "Art Design", "media": "https://ipfs.io/ipfs/Qme7ss3ARVgxv6rXqVPiikMJ8u2NLgmgszg13pYrDKEoiu", "copies": 1}}' --accountId $ID --deposit 0.1
ANSWER
Answered 2022-Feb-09 at 13:22There are several issues in the existing repository for /mint_nft
.
The REST-API implemented doesn't follow the correct format when minting an NFT. I have created a PR to address the issue
In short, the function call to mint an NFT is missing one argument, receiver_id
, and the format and name of metadata
is not correct. It should be token_metadata: {} // type is object, not string
.
If we change the postData to
QUESTION
I'm trying to store data to ipfs via PHP, I use curl to communicate with API , it works fine on my local node, but I want to use an external node from infura.io
but for some reason, ipfs.infura.io is refusing my connection via php even a simple command like ... I've tried it on my localhost as well as a couple of servers
here is a simple endpoint that you can open in the browser and get the output
https://ipfs.infura.io:5001/api/v0/pin/add?arg=QmeGAVddnBSnKc1DLE7DLV9uuTqo5F7QbaveTjr45JUdQn
but when I try to open it via php i get
Failed to connect to ipfs.infura. io port 5001: Connection refused
or when using another method like file_get_contents
file_get_contents(ipfs.infura.io:5001/api/v0/pin/add?arg=QmeGAVddnBSnKc1DLE7DLV9uuTqo5F7QbaveTjr45JUdQn): failed to open stream: Connection refused
i've tried it on local host and multiple server , i get the same result even via ssh command line
any idea why is this happening ?
here is a simplified version n of my code

QUESTION
I would like to get n ERC721 token with a specific "dna". See the metadata below:
...ANSWER
Answered 2022-Feb-01 at 18:29EVM contracts are not able to read offchain data (the JSON file) directly. You'd need to use an offchain app (or an oracle provider such as Chainlink) for that to feed the offchain data to the contract.
So it's much easier to just query the data from an offchain app.
Example using node.js and the web3 package for querying the contract:
QUESTION
I am working on a blockcahin based image sharing website in ethereum
...ANSWER
Answered 2022-Jan-10 at 15:28You cannot delete an image from IPFS the way you interact with the database. (giving the IPNS of the content and user sends an http request to delete it).
When you upload your content, you pin it to a node. Now the thing is the node that your content is pinned should be unpinned. So if you have a control over that node, If you started your own node, you unpin it and then ipfs will garbage collect it.
https://docs.ipfs.io/concepts/persistence/#garbage-collection
But if an image has been added and copied to another node, any person with the fingerprint can find it again. So whoever controls that node should unpin it.
