Metamask does not guess the currency symbol && Not Metamask connection (Solved) && Problem following https://docs.cronos.org/for-node-hosts/running-nodes/local-devnet: gas prices; got: 0 required: 7: insufficient fee (Solved)

[EAG-es]

I am following https://docs.cronos.org/for-node-hosts/running-nodes/local-devnet

Option 2

Modify the configuration script: ./scripts/cronos-devnet.yaml 

Use pystarport

pystarport serve --config ./scripts/cronos-devnet.yaml 
the serve command would truncate all the blocks previously generated and regenerate a new genesis block, which means you'll also lose all of your transaction records. 
the accounts' information is generated in: data/cronos_777-1/accounts.json
If you wish to restart the chain with the existing blocks, please run pystarport with start command:
pystarport start --config ./scripts/cronos-devnet.yaml

Operations Key management

cronosd keys add signer2 --recover --keyring-backend test
(The bip39 mnemonic, as can be found in data/cronos_777-1/accounts.json, in “mnemonic” field)
{"name": "signer2", "type": "local", "address": "crc1q04jewhxw4xxu3vlg3rc85240h9q7ns6hglz0g", "pubkey": "{\"@type\":\"/ethermint.crypto.v1.ethsecp256k1.PubKey\",\"key\":\"A3K9+A9hnuhqkxn+/GHLVZwFthvAERmvpSupb0d44WtD\"}", "mnemonic": "night renew tonight dinner shaft scheme domain oppose echo summer broccoli agent face guitar surface belt veteran siren poem alcohol menu custom crunch index"}

See balance

sudo apt install jq
cronosd q bank balances crc1q04jewhxw4xxu3vlg3rc85240h9q7ns6hglz0g -o json | jq
  {
  "balances": [
    {
      "denom": "basetcro",
      "amount": "30000000000000000000000"
    }
  ],
  "pagination": {
    "next_key": null,

Transfer token to another address

cronosd keys add Bob --keyring-backend test

- address: crc1jyylfq5wq8dg7shyz8chgyl7tv37z02qq43ms2
  name: Bob
  pubkey: '{"@type":"/ethermint.crypto.v1.ethsecp256k1.PubKey","key":"AgsFPVdkEm0CM1sWibpvng7gAv+Z7t9ZbcOdVxbqiK11"}'
  type: local

**Important** write this mnemonic phrase in a safe place.

It is the only way to recover your account if you ever forget your password.

Now we can transfer tokens to Bob, for example you can send 1basetcro to Bob's address by

cronosd tx bank send signer2 crc1jyylfq5wq8dg7shyz8chgyl7tv37z02qq43ms2 1basetcro --keyring-backend test --chain-id cronos_777-1

#FF0000 Error:

gas prices; got: 0 required: 7: insufficient fee"

#00FF00 Questions:

How can I give funds for the transaction?

Why does not have funds to pay transactions but has funds (30000000000000000000000 basetcro)?

Thanks for your support.

@EAG-es Have you try set --gas-prices when do tx bank send?

[EAG-es]

--gas-prices

It worked!!! (It would be a great help to update the doc.)

cronosd tx bank send signer2 crc1jyylfq5wq8dg7shyz8chgyl7tv37z02qq43ms2 1basetcro --keyring-backend test --chain-id cronos_777-1 --gas-prices 7.0basetcro

Now I have a new problem.... I cannot set Metamask local network configuration: cronosd config

{
	"chain-id": "331110",
	"keyring-backend": "os",
	"output": "text",
	"node": "tcp://localhost:26657",
	"broadcast-mode": "sync"
}
This parameters are not acceptable by Metamask:

How do I connect Metamask to the local Cronos network?

Thanks

26657 is the cometbft rpc server port, 8545 is the default eth json-rpc port.

26657 is the cometbft rpc server port, 8545 is the default eth json-rpc port.

localhost:8545 has not anything listening at it, after pystarport start --config ./scripts/cronos-devnet.yaml

Can you please give me a reference to any doc to make cronosd available to Metamask?

Thanks

you might find and match related ports in here

The python source code here does not give me clues... Where is base_port defined? Is it defined in a configuration file? (genesis?) I cannot find any way to define/active/detect json-rpc port (service)...

My Local network should be able to interact with Metamask and Smart Contracts and with Keplr (desirable) but I cannot find any documentation/manual about it...

Hope you can help me...

[mmsqe]

have you try http://localhost:26651, the url should match with your json-rpc address in app.toml

[yihuang]

the json-rpc address to be used in metamask is defined in the app.toml, json-rpc.address.

[EAG-es]

331110 have you try http://localhost:26651, the url should match with your json-rpc address in app.toml the json-rpc address to be used in metamask is defined in the app.toml, json-rpc.address. Yes It worked! Hope it will be soon in the doc. 🥇

[EAG-es]

I have been able to connect LocalDev Node to Metamask...

There is an issue with network ID 777. It is already used by cheapETH... So I changed to other number. But Metamask does not detect the Currency Symbol: Ticker symbol verification data is currently unavailable, please make sure the symbol you entered is correct. It will impact the conversion rates you see for this network

How can I tell Metamask the Currency Symbol?

Thanks...

[mmsqe]

@EAG-es you might change try with CRO
