We generate datum script using below :

cardano-cli transaction hash-script-data --script-data-file ${datum_name}.datum

It generates the datum script. once we have datum we need to incluide it into transaction
that is generated on cli again

cardano-cli transaction build
--alonzo-era
--tx-in ${utxoin}
--tx-out ${SCRIPT_ADDR}+${LOCK_AMNT}
--tx-out-datum-hash ${hashes[0]}
--metadata-json-file metadata.json \

Please let me know how to do above using nami-wallet-api?

hello, here for me on file and line appear an error, look bellow:

erro:  Error: expected instance of Value

the funny thing is that it is returning yes, a Value instance, I have already debugged everything and it always returns a Value instance.

the libs they are in same versions of this package, has anyone ever experienced this? thanks!

When you are generating a transaction you are sending some assets.
When you send the transaction you can add optional parameters like metadata and/or datum.
datum is used by smart contract since it's the only data that smart contract can see.
how to construct more complex transaction that will include datum?

Hi,

I've tried to use your provided NPM package. Sadly, I've been running into memory leak.

I am trying to use this
https://github.com/Felippo001/nami-wallet-api
to connect my react app to Nami wallet using cardano-serialisation-lib.

async function loadWasm (){
    try {
      const wasm = await import("@emurgo/cardano-serialization-lib-browser");
      setWasm(wasm);
    } catch (err) {
      console.error(`Unexpected error in loadWasm. [Message: ${err.message}]`);
    }
  };

I am using this to load cardano serialisation lib.
The error I am getting while i npm start
I have already installed node-fetch and also @emurgo/cardano-serialization-lib-browser
Module not found node:http in node-fetch/src

node-fetch is causing problems with webpack and parcel because of the node: prefix

here's my dependencies in the package.json file
"devDependencies": { "html-loader": "^2.1.2", "html-webpack-plugin": "^5.3.2", "webpack": "^5.64.4", "webpack-cli": "^4.9.1", "webpack-dev-server": "^4.6.0" }, "dependencies": { "nami-wallet-api": "^1.1.9", "node-fetch": "^3.1.0" }

this issue seems similar

Hi, Can you please tell how it can be use in React Js. When ever i try to download nami-wallet-api in React project it gives me errors for # Blob etc.

unable to mint using this package. can you help me to resolve this issue?

Not sure why, but on testnet I always get a cannot read properties of undefined (reading 'toString') error.

Tested on Chrome & Brave browser. Flipping Nami to mainnet, and it does work again.

I'm having a weird issue where everything seems to be loading correctly, however when it comes to running the getNetworkId function it throws this error: TypeError: Nami.getNetworkId is not a function

const WASM_lib = await import('@emurgo/cardano-serialization-lib-browser/cardano_serialization_lib')
const nami_lib = await import('nami-wallet-api')
const Nami = await nami_lib.NamiWalletApi(
    window.cardano.nami,
    process.env.NEXT_PUBLIC_BLOCKFROST_PROJECT_ID,
    WASM_lib
)

await Nami.enable()
console.log('isEnabled', await Nami.isEnabled())

console.log('Nami', Nami);
console.log('Nami.getNetworkId', Nami.getNetworkId);
const networkId = await Nami.getNetworkId();

isEnabled returns as true, Nami shows all the functions including getNetworkId, and logging getNetworkId shows the function.

Is there anything obviously wrong with this? Thanks!

Getting the following error from a wallet that has enough ada in it? any recommendations?
