eztz's Issues

Possibility to use in node.js app

Hi, is there some possibility to use this library in node.js desktop app (electron) with npm or as an external library ? Thank you very much

I am attesting that this GitHub handle maximctrl is linked to the Tezos account tz1Wo8UZopjyVg7i1XZxPqxBrMpBw3vMngRY for tzprofiles sig:edsigtZeAShxxvtTWTFX7gTAdukng8eE4eKs4LWoQv42Pf7bGzDdqNzNEfXmXZAum67yq5PSWaodE8nXqjYKJLxorKZVYN65dFq

Inability to create multiple transactions (counter error)

The eztz.contract.send method successfully performs transactions, but when trying to make several consecutive transactions, the following error occurs:

Error: Counter XXX already used for contract tz------------XXX (expected YYYY)

The counter lags behind the required value by 1-2

Unsupported Media Type

HI,

I am running zeronet tezos node and below command works fine with curl.**

{"hash":"BKiY3ohPNvLVG5pcx7MY4viWfoV7dF4xD9hzAoeRNc7TvveZZhN"}

Now I made this html file using eztz library.
( I modified defaultProvider = "http://localhost:8732" in main.js and npm run-script build. And I used eztz.min.js that built newly)

 <!DOCTYPE html>
 <html>
 <head>
 <script src="./eztz.min.js"></script>
 </head>
 
 <body>
 	<script>
 		eztz.node.query("/blocks/head/hash").then(function(res){
 		  console.log(res);
 		}).catch(function(e){});
 
 	</script>
 </body>
 </html>

But it gives an error.

(anonymous) @ eztz.min.js:8
query @ eztz.min.js:8
(anonymous) @ 4.html:9
4.html:1 Failed to load http://localhost:8732/blocks/head/hash: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access. The response had HTTP status code 415.

415 error is related to content-type or something. I am not sure.
Is there something wrong or missed something?

Send transaction with metadata?

Is it possible to add metadata to a transaction? We are running a baker and would like to track our payouts with an ID.

Thanks.

Status of NPM module?

Status of the NPM module?

I think the package.json is missing some fields and XMLHttpRequest needs to be polyfilled with xhr2

sexp2mic function returns wrong result

let parameter = "{ DROP ; NIL operation ; PUSH address KT1LsXWNrbvbtkjHjryJLEPyWESy4vPzrxzh ; CONTRACT unit ; ASSERT_SOME ; PUSH mutez 1000000 ; UNIT ; TRANSFER_TOKENS ; CONS }";

eztz.utility.sexp2mic(parameter) return as follows:

Babylon changes?

Are there going to be changes made to this library for the Babylon proposal?

Can't connect to alphanet node

Expected Behavior
Show balance of tz account on alphanet

Current Behavior
Access to XMLHttpRequest at 'http://:8732/chains/main/blocks/head/context/contracts//balance' from origin 'null' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Context (Environment)
I have set up a node on GCP, I am trying to connect to this node from a local machine via: eztz.node.setProvider("http://:8732");

Get all transactions from address?

Are there plans to add a request that would return all transactions from a given address?

tz2/tz3 prefixes typo?

Hi, was just browsing to find the b58 encoding tz1/2 prefixes, when I found this. Is this a typo?

eztz/dist/eztz.cli.js

Lines 13 to 14 in cfdc4fc

    
           tz2: new Uint8Array([6, 161, 161]), 
        
           tz2: new Uint8Array([6, 161, 164]),

Moving to TypeScript (or some functional lang)

@stephenandrews what do you thing about moving lib to TypeScript (or some functional lang)?
TypeScript or some functional static lang will ensure correctness and will leave less space for bugs.

what is wm in sign()?

I am tring to sign a transaction by Library, but I don't know how can I using the function sign:

  sign: function (bytes, sk, wm) {
    var bb = utility.hex2buf(bytes);
    if (typeof wm != 'undefined') bb = utility.mergebuf(wm, bb);
    const sig = library.sodium.crypto_sign_detached(library.sodium.crypto_generichash(32, bb), utility.b58cdecode(sk, prefix.edsk), 'uint8array');
    const edsig = utility.b58cencode(sig, prefix.edsig);
    const sbytes = bytes + utility.buf2hex(sig);
    return {
      bytes: bytes,
      sig: sig,
      edsig: edsig,
      sbytes: sbytes,
    }
  }

What is vm ?

Uncompiled Ledger Code

The Ledger module is looking pretty good. Will you share the uncompiled version?

publish npm module

Why isn't the module published on npm? @stephenandrews

get address from publicKey

Can be useful to have a method to get the address from publicKey:

function getAddress(publicKey) {
  const hash = sodium.crypto_generichash(20, publicKey);
  const pkh = Utility.b58cencode(hash, Prefix.tz1)
  return pkh
}

and something else for longer privateKey

Originate a contract with string list

I'm trying to originate a contract but I get "Failed to parse the request body".
the code is : parameter unit;
storage (list string);
code { CDR ; NIL operation ; PAIR };

and the init : { "hello" }

Please help!

Support for voting?

Any expected work on supporting voting?

Question about mutez and totez formatting

This isn't an issue - I'm looking for clarification. In main.js there are two formatters for Tezos values and I am a bit confused.

In the utility object, the two formatters are:

totez: m => parseInt(m) / 1000000,
mutez: function(tz) {
    return new BN(new BN(tz).toFixed(6)).multipliedBy(1000000).toString();
},

I am sending successful transfers using eztz.rpc.transfer - the values I supply for the transactions are floats like 4.1 or 0.1. These are accurately outputting the correct amount of xtz taking place in the transfer (taking place through a Ledger integration on my front-end).

I am confused because although it works and the values match up (4.1xtz), it seems in this case that neither totez or mutez formatters are being used. Any ideas on what I'm missing here?

generateKeysNoSeed undefined in minified eztz

generateKeysNoSeed should either be included in eztz.min.js or its documentation should state that it's a CLI only function.

Error calling a contract method

I'm having this error:

Failed to parse the request body: No case matched:
  At /kind, unexpected string instead of endorsement
  At /kind, unexpected string instead of seed_nonce_revelation
  At /kind, unexpected string instead of double_endorsement_evidence
  At /kind, unexpected string instead of double_baking_evidence
  At /kind, unexpected string instead of activate_account
  At /kind, unexpected string instead of proposals
  At /kind, unexpected string instead of ballot
  At /kind, unexpected string instead of reveal
  Unhandled error (Invalid_argument "Z.of_substring_base: invalid digit")
  At /kind, unexpected string instead of origination
  At /kind, unexpected string instead of delegation

Trying to call a contract method:

function main(const action: entry_action; var finance_storage: finance_storage): (list(operation) * finance_storage) is
  block {
    skip
  } with case action of
    | Deposit(param) -> depositImp(finance_storage)
    | Withdraw(param) -> withdrawImp(finance_storage)
    end;

compiled code

parameter (or (unit %deposit) (unit %withdraw)) ;

I'm making the call like so:

  const v3FullPoolAddress = "KT1EufKiVMbL6r4T2whQT88crUZJM7J3SW66";
  const bobKeys = {
    pk: "edpktvrjBvRB7zJGEQKBFpwGS2rb12VD4ibTv7Kqgv9yAi6ARW3vQy",
    sk: "edsk3k86EP8oqGfgpmVq5XPpjwJTb3ivmDUpZw12j13dvnqnU3PCnM",
    phk: "tz1P4iVZLrBEjqNKUDBe7bqV8CB2AQ51ZKf8"
  };

  eztz.contract
    .send(v3FullPoolAddress, bobKeys.phk, bobKeys, 100, "(Left Unit)", 0.5)
    .then(res => {
      console.log(`Deposit Call from bob ${JSON.stringify(res)}`);
    })
    .catch(console.log);

calling the contract using tezos-client works fine, any idea what can I be doing wrong?

Getting "Empty Response" as rpc response

Hi,
On using the defaultProvider in eztz.cli.js i.e.tezrpc.me/zeronet, it returns Empty Response as the result to any query command (I've checked it for rpc.getHead()). Kindly suggest a fix for this or suggest some other public rpc node available for Tezos Zeronet. Thanks in advance!

rpc.tezrpc.me is offline

https://rpc.tezrpc.me returns 404

Failing injection/operation on betanet

Hi Stephen,

First - this is a remarkable library BTW - great work!

I'm trying to adapt the code to work on betanet and I'm having some limited success creating a transaction...

I have substituted in the betanet protocol "PsYLVpVvgbLhAhoqAkMFUo6gudkJ9weNXhUYCiLDzcUpFpkk8Wt" and so far the process works through forge/operations, preapply/operations but when I send the signed bytes string to injection/operations I'm getting a 400 response with:

"Failed to parse the request body: JSON.of_buffer illegal number\n(98f0b430dcaf1aafb516fe33383efe71b78c1bae410fc11582042c8c7524979207000007a781154e1ae1d0a9cc8ec0934711e7d6d905be0091fe020000002ee6ce422dc26471442bc3425f8f09dfa45fd61a018d13bcee26f4f1a4c61ca108000007a781154e1ae1d0a9cc8ec0934711e7d6d905bee80792fe02f4030098e23000003

Do you know what this might be?

Kind Regards,
Guyon

Unable to query alphanet

Hi, this library works flawlessly for the mainnet, but here I'm trying to connect to the Alphanet of the Tezos network and trying to simulate all the standard transactions as on the mainnet. Can you please guide me as to how how I can use one of your rpc providers to query the Alphanet. I explored every directory of this library to connect to to Alphanet, but always received "Empty Response Returned" despite the http status code being 200.
Please provide the appropriate solution to this. Thank you!
