Deploy a Testnet
Starting Gaiad
Start the full node:
gaiad start
Check the everything is running smoothly:
gaiacli status
Generate keys
You'll need a private and public key pair (a.k.a. sk, pk
respectively) to be able to receive funds, send txs, bond tx, etc.
To generate your a new key (default ed25519 elliptic curve):
KEYNAME=<set_a_name_for_your_new_key>
gaiacli keys add $KEYNAME
Next, you will have to enter a passphrase for your$KEYNAME
key twice. Save the _seed phrase _in a safe place in case you forget the password.
Now if you check your private keys you will see the $KEYNAME
key among them:
gaiacli keys show $KEYNAME
You can see your other available keys by typing:
gaiacli keys list
Save your address and pubkey into a variable
MYADDR=<your_newly_generated_address>
MYPUBKEY=<your_newly_generated_public_key>
IMPORTANT: We strongly recommend to NOT use the same passphrase for your different keys. The Tendermint team and the Interchain Foundation will not be responsible for the lost of funds.
Getting Coins
Go to the faucet in http://atomexplorer.com/ and claim some coins for your testnet by typing the address of your key, as printed out above.
Send tokens
gaiacli send --from=$MYADDR --amount=1000fermion --chain-id=<name_of_testnet_chain> --sequence=1 --name=$KEYNAME --to=<destination_address>
The --amount
flag defines the corresponding amount of the coin in the format --amount=<value|coin_name>
The --sequence
flag corresponds to the sequence number to sign the tx.
Now check the destination account and your own account to check the updated balances (by default the latest block):
gaiacli account <destination_address>
gaiacli account $MYADDR
You can also check your balance at a given block by using the --block
flag:
gaiacli account $MYADDR --block=<block_height>
Custom fee (coming soon)
You can also define a custom fee on the transaction by adding the --fee
flag using the same format:
gaiacli send --from=$MYADDR --amount=1000fermion --fee=1fermion --chain-id=<name_of_testnet_chain> --sequence=1 --name=$KEYNAME --to=<destination_address>
Transfer tokens to other chain
The command totransfer
tokens to other chain is the same assend
, we just need to add the--chain
flag:
gaiacli transfer --from=$MYADDR --amount=20fermion --chain-id=<name_of_testnet_chain> --chain=<destination_chain> --sequence=1 --name=$KEYNAME --to=<sidechain_destination_address>
Staking: Add a Validator
Get your public key by typing:
gaiad show_validator
The returned value is your validator address in hex. This can be used to create a new validator candidate by staking some tokens:
gaiacli declare-candidacy --amount=500fermions --pubkey=$PUBKEY --address-candidate=$MYADDR --moniker=satoshi --chain-id=<name_of_the_testnet_chain> --sequence=1 --name=$KEYNAME
You can add more information of the validator candidate such as--website
, --keybase-sig
or additional--details
. If you want to edit the candidate info:
gaiacli edit-candidacy --details="To the cosmos !" --website="https://cosmos.network"
Finally, you can check all the candidate information by typing:
gaiacli candidate --address-candidate=$MYADDR --chain-id=<name_of_the_testnet_chain>
To check that the validator is active you can find it on the validator set list:
basecli validatorset <height>
*Note: Remember that to be in the validator set you need to have more total power than the Xnd validator, where X is the assigned size for the validator set (by default X = 100
).
Delegating: Bonding and unbonding to a validator
You can delegate (i.e. bind) Atoms to a validator to obtain a part of its fee revenue in exchange (the fee token in the Cosmos Hub are Photons).
gaiacli delegate --amount=10fermion --address-delegator=$MYADDR --address-candidate=<bonded_validator_address> --shares=MAX --name=$KEYNAME --chain-id=<name_of_testnet_chain> --sequence=1
If for any reason the validator misbehaves or you just want to unbond a certain amount of the bonded tokens:
gaiacli unbond --address-delegator=$MYADDR --address-candidate=<bonded_validator_address> --shares=MAX --name=$KEYNAME --chain-id=<name_of_testnet_chain> --sequence=1
You can unbond a specific amount ofshares
(eg:12.1
) or all of them (MAX
).
You should now see the unbonded tokens reflected in your balance and in your delegator bond :
gaiacli account $MYADDR
gaiacli delegator-bond --address-delegator=$MYADDR --address-candidate=<bonded_validator_address> --chain-id=<name_of_testnet_chain>
Relaying
Relaying is key to enable interoperability in the Cosmos Ecosystem. It allows IBC packets of data to be sent from one chain to another.
The command to relay packets is the following:
gaiacli relay --from-chain-id=<name_of_testnet_chain> --to-chain-id=<destination_chain_name> --from-chain-node=<host>:<port> --to-chain-node=<host>:<port> --name=$KEYNAME --sequence=1
