qosgroup / litewallet Goto Github PK

We should add two buttons for a pending transaction: accelerate/cancel, then prompt the additional gas fee, and the possible failure in case of cancellation. This will make our life much more easier.

This article explains how it works: https://medium.com/@jgm.orinoco/releasing-stuck-ethereum-transactions-1390149f297d

It is weird that cosmos core team decided to create internal package under the x/bank module. It makes the reconstruction over cosmos v0.35.0 difficult due to the reason internal package not allowed to use with Golang importing policy.
Some local code migration have been done into the branch dev-cosmosv35.0, however, there are still consequences as what the internal package use has brought.
One issue was raised to the cosmos community, resulting in some brief feedback following closure. use of internal package github.com/cosmos/cosmos-sdk/x/bank/internal/types not allowed
I have no idea about why they do in this way.
However, the reconstruction should be continued with more efforts from our side:

• cannot encode unregistered concrete type sdksource.MsgSend

This could be fixed only under the litewallet repo with local efforts.

It's not so complicated that to make the seed or the salt with an original plaintext password. However, this could make the wallet not so secured because fo the source code open to community. There could be some security threat underline. So there should be an approach to make the wallet more secured.

It is an enhancement for current querying process for the detailed Tnx, this feature is initiated from Frontend user with receipt.
Currently, this part is resolved from block data via Qmoon. We think there is some trade-off here.
New interface should be designed here to query Tnx with tags from cosmos networks.

latest dapp link should be provided in the readme of the project, so everyone access the repo could download the dapps to make full use of it.

"LitewalletEthGetErc20Account" interface reports error: "abi: cannot marshal in to go slice: offset"

#feat: ETH 2.0 access
The litewallet should take some step into the most advanced blockchains in the industry, e.g. the ETH 2.0 beacon chain.
There could be some beacon chain nodes available in Infura or self established one.
Public apis should be exposed outside.

与#2 类似的需求，查询状态的新增HTTP REST API接口，移动端前端集成，SDK部分维护原始的RPC方式

From next phase on, lite wallet will be fully supporting QOS chain on latest version and so on.

Per request from FE, one new function should be provided with nonce at latest block state under the specific account.

It is OK for value less than 1 which is meant for FE implementation for fraction value of erc20 tokens.
However, for the value greater than 1, this is not the case. Need to be reviewed with code and more specific testing.

To collaborate with the enhancement for the comming #2 , some SDK code should be added to support the splitting including below parts:

1. package sdksource, besides Tnx Transfer,

• Delegate
• UnbondingDelegation
• WithdrawRewards
  new Tnx designed if any

2. package slim for QOS part,

• Transfer
  current interfaces from JianQian, if needed ,should be migrated too @ms8922

Transaction gas price is too low. There is another transaction with same nonce in the queue. Try increasing the gas price or incrementing the nonce.

According to FE design, the input of gasFee is consisting of gasPrice * gasLimit, to make the SDK and FE more feasible!

error feedback from the chain with error decoding transaction after modifying the codec for transfer module x/bank to locally repo. There is definitely something to do with this locally migration and more investigation is needed to take into.

The new function collaboration with @zhangwen9229 , to generate a Tnx to send to tendermint full node.

As litewallet SDK itself, specific function on round robin selection is to be designed.
The draft code could be followed as below pattern if no further endurance:

node discovery with round-robin algorithm
var i = 0
var servers = []string{"127.0.0.1:8000", "127.0.0.1:8001", "127.0.0.1:8003"}

// Balance returns one of the servers based using round-robin algorithm
func Balance() string {
	server := servers[i]
	i++

	// it means that we reached the end of servers
	// and we need to reset the counter and start
	// from the beginning
	if i >= len(servers) {
		i = 0
	}
	return server
}


func main() {
	// requests loop
	for i := 0; i < 20; i++ {
		fmt.Println(Balance())
	}
}

重构当前广播交易模式以支持REST API接口 #QOSGroup/qmoon#122
当前：build -> sign -> send via RPC
Feat：build -> sign -> send via REST
litewallet所做的是前两步build -> sign，前端集成HTTP API接口调用将签名的交易广播出去。类似的功能在后台充值提现中有实现https://github.com/cosmos/cosmos-sdk/commit/b1dce76c9684e3b6d0c7030157bb0cb5ff3be9b9
剩余delegate，unbondingdelegation，withdraw与前述版本一致；
新增redelegate, .etc

For the diversity of the wallet application in around the world, there are some requirements on the diversity of the mnemonic language, here are the lists:

1. Chinese with both simplified and traditional one;
2. Korean
3. English

The cosmos hub-3 upgrading is coming, a new branch corresponding to this is under development.
There could be high priority on it due its deadline.

When one single Tx with multi-coins is to be generated within an ITx in litewallet/slim pack for QOS transfer scenario.
The ParseCoins method is not compatible with latest code.
Here is origin code from QOSGroup/qos :

// Parse QOS and QSCs from string
// str example : 100qos,100qstar
func ParseCoins(str string) (btypes.BigInt, QSCs, error) {
	if len(str) == 0 {
		return btypes.ZeroInt(), QSCs{}, nil
	}
	reDnm := `[[:alpha:]][[:alnum:]]{2,15}`
	reAmt := `[[:digit:]]+`
	reSpc := `[[:space:]]*`
	reCoin := regexp.MustCompile(fmt.Sprintf(`^(%s)%s(%s)$`, reAmt, reSpc, reDnm))

	arr := strings.Split(str, ",")
	qos := btypes.ZeroInt()
	qscs := QSCs{}
	for _, q := range arr {
		coin := reCoin.FindStringSubmatch(q)
		if len(coin) != 3 {
			return btypes.ZeroInt(), nil, fmt.Errorf("coins str: %s parse faild", q)
		}
		coin[2] = strings.TrimSpace(coin[2])
		amount, err := strconv.ParseInt(strings.TrimSpace(coin[1]), 10, 64)
		if err != nil {
			return btypes.ZeroInt(), nil, err
		}
		if strings.ToLower(coin[2]) == "qos" {
			qos = btypes.NewInt(amount)
		} else {
			qscs = append(qscs, &QSC{
				coin[2],
				btypes.NewInt(amount),
			})
		}

	}

	return qos, qscs, nil
}

The code in current patch is too old and need to be updated immediately!

The tendermint LCD function is just experimental not practical for use. It could be followed with this ticket:tendermint/tendermint#3335

Due to the cosmoshub-3 upgrading plan on 15th Sep., a testnet should be established for testing below:

1. Mobile frontend
2. Litewallet
3. Qmoon
