/*
Package params defines the simulation parameters for the Kava app.
It contains the default weights used for each transaction used on the module's
simulation. These weights define the chance for a transaction to be simulated at
any gived operation.
You can repace the default values for the weights by providing a params.json
file with the weights defined for each of the transaction operations:
{
"op_weight_msg_send": 60,
"op_weight_msg_delegate": 100,
}
In the example above, the `MsgSend` has 60% chance to be simulated, while the
`MsgDelegate` will always be simulated.

# Contrib
Resources and examples for running and interacting with the kava blockchain.
Resources and examples for running and interacting with the kava blockchain. `contrib` contains sample genesis files, example governance proposals, and rest-server request examples for different versions of kava.
## testnet-4000
kava-testnet-4000 introduces the cdp and auction modules, allowing users to create CDPs and mint usdx as well as participate in auctions.
Configuration and rest-server interaction files are available in the [testnet-4000](./testnet-4000/README.md) directory.
## testnet-5000
kava-testnet-5000 introduces the bep3 modules, allowing users to transfer BNB between the bnbchain testnet and kava.
Configuration and rest-server interaction files are available in the [testnet-5000](./testnet-5000/README.md) directory.
## dev
During development new features offer require modifications to the genesis file. The dev directory houses these genesis files.

# Testnet-5000
Testnet-5000 introduces transfers between Kava and Bnbchain via BEP3.
This guide will walk you through interacting with the blockchains and transferring coins via the rest server. To send transactions, we'll create an unsigned request, sign it, and broadcast it to the Kava blockchain.
## Rest server requests
### Setup
We'll be using Kava's CLI to build, sign, and broadcast the transactions:
```bash
# Download kvcli
make install
```
Before making a request, query account information for the signing account. Note the 'accountnumber' and 'sequence' fields, we'll need them later in order to send our request:
```bash
kvcli q auth account $(kvcli keys show testuser -a)
```
### Create swap
Use the example file in `rest_examples/create-swap.json` to format the request. First, update the header parameters 'from', 'chain-id', 'account_number', 'sequence'.
Next, we'll update the swap's creation parameters. For that, we need a unique random number that will be used to claim the funds.
WARNING: Don't use `calc-rnh` for the generation of secrets in production. These values should be generated client-side for the safety of user funds.
```bash
# Generate a sample random number, timestamp, and random number hash
kvcli q bep3 calc-rnh now
# Expected output:
# Random number: 110802331073994018312675691928205725441742309715720953510374321628333109608728
# Timestamp: 1585203985
# Random number hash: 4644fc2d9a2389c60e621785b873ae187e320eaded1687edaa120961428eba9e
```
In the same json file, populate each of the following parameters
- from
- to
- recipient_other_chain
- sender_other_chain
- random_number_hash
- timestamp
- amount
- expected_income
- height_span
- cross_chain
Once each parameter is populated, it's time to create our swap:
```bash
# Create an unsigned request
curl -H "Content-Type: application/json" -X POST -d @./contrib/testnet-5000/rest_examples/create-swap.json http://127.0.0.1:1317/bep3/swap/create | jq > ./contrib/testnet-5000/rest_examples/create-swap-unsigned.json
# Sign the request
kvcli tx sign ./contrib/testnet-5000/rest_examples/create-swap-unsigned.json --from testnetdeputy --offline --chain-id testing --sequence 0 --account-number 5 | jq > ./contrib/testnet-5000/rest_examples/broadcast-create-swap.json
# Broadcast the request
kvcli tx broadcast ./contrib/testnet-5000/rest_examples/broadcast-create-swap.json
```
The tx broadcast will log information in the terminal, including the txhash. This tx hash can be used to get information about the transaction, including the swap creation event that includes the swap's ID:
```bash
# Get information about the transaction
curl -H "Content-Type: application/json" -X GET http://localhost:1317/txs/81A1955216F6D985ECB4770E29B9BCED8F73A42D0C0FD566372CF673CCB81587
```
Congratulations, you've just created a swap on Kava! The swap will be automatically relayed over to Bnbchain where it it can be claimed using the secret random number from above.
# Claim swap
Only unexpired swaps can be claimed. To claim a swap, we'll use the secret random number that matches this swap's timestamp and random number hash.
Generally, claimable swaps must be created on Bnbchain.
// TODO: add link to Bnbchain document with interaction steps
Use the example file in `rest_examples/claim-swap.json` to format the request. Again, update the header parameters 'from', 'account_number', 'sequence'. Check your account using the command from above to ensure that the parameters match the blockchain's state.
In the same json file, populate each listed parameter:
- swap_id
- random_number
Once the `swap_id` parameter is populated, it's time to claim our swap:
```bash
# Create an unsigned request
curl -H "Content-Type: application/json" -X POST -d @./contrib/testnet-5000/rest_examples/claim-swap.json http://127.0.0.1:1317/bep3/swap/claim | jq > ./contrib/testnet-5000/rest_examples/claim-swap-unsigned.json
# Sign the request
kvcli tx sign ./contrib/testnet-5000/rest_examples/claim-swap-unsigned.json --from user --offline --chain-id testing --sequence 0 --account-number 1 | jq > ./contrib/testnet-5000/rest_examples/broadcast-claim-swap.json
# Broadcast the request
kvcli tx broadcast ./contrib/testnet-5000/rest_examples/broadcast-claim-swap.json
```
# Refund swap
Only expired swaps may be refunded.
Use the example file in `rest_examples/refund-swap.json` to format the request. Again, update the header parameters 'from', 'account_number', 'sequence'. Check your account using the command from above to ensure that the parameters match the blockchain's state.
In the same json file, populate each parameter:
- swap_id
Once the `swap_id` parameter is populated, it's time to refund our swap:
```bash
# Create an unsigned request
curl -H "Content-Type: application/json" -X POST -d @./contrib/testnet-5000/rest_examples/refund-swap.json http://127.0.0.1:1317/bep3/swap/refund | jq > ./contrib/testnet-5000/rest_examples/refund-swap-unsigned.json
# Sign the request
kvcli tx sign ./contrib/testnet-5000/rest_examples/refund-swap-unsigned.json --from user --offline --chain-id testing --sequence 0 --account-number 1 | jq > ./contrib/testnet-5000/rest_examples/broadcast-refund-swap.json
# Broadcast the request

///////////////////////////////////////////////////////////////////////////////////////
///// IF YOU FOLLOW THESE INSTRUCTIONS ALL THE TESTS SHOULD PASS THE FIRST TIME ///////
///////////////////////////////////////////////////////////////////////////////////////
Instructions on how to run the `dredd` tests
(Prerequisite) Make sure that you have the latest versions of `node` and `npm` and `npx` installed. Then install `dredd` globally using the following command folder:
`npm install dredd --global`
(Running tests) Run `make test_dredd` from the `kava` directory.
This builds the `test.go` file, creates the genesis state for the blockchain, starts the blockchain, starts the rest server, sends the required transactions to the blockchain, runs all the `dredd` tests, shuts
down the blockchain, cleans up, and propagates up an error code if the tests do not all pass.
**IMPORTANT** - It takes about 3 minutes for the script to run and complete:
**When you run the script 62 tests should pass and zero should fail**
(Shutdown) If the script fails or you stop it midway using `ctrl-c` then you should manually stop the blockchain and rest server using the following script. If you let it complete
it will automatically shut down the blockchain, rest server and clean up.
`./stopchain.sh`
**DEBUGGING NOTE**: If you start getting `Validator set is different` errors then you need to try starting the chain from scratch (do NOT just use `unsafe-reset-all`, instead use `./stopchain.sh` and then `./run_all_tests.sh`)
