Main chain wallets

There is a wallet with GAS that used for contract deployment: wallets/wallet.json. This wallet has one account with empty password.

$ neo-go wallet nep17 balance \
    -w wallets/wallet.json \
    -r http://main-chain.neofs.devenv:30333 
   
Account NbUgTSFvPmsRxmGeWpuuGeJUoRoi6PErcM
GAS: GasToken (d2a4cff31913016155e38e474a2c06d08be276cf)
        Amount : 9978.0074623
        Updated: 34

If you want to operate in main chain with your personal wallet (e.g. to make a deposit in NeoFS contract), you can transfer GAS from there.

Create new wallet.

$ neo-go wallet init -a -w wallets/neofs1.json

Enter the name of the account > neofs1
Enter passphrase >
Confirm passphrase >

{
    "version": "3.0",
    "accounts": [
        {
            "address": "NXnzw3J9VvKXjM1BPAJK4QUpTtEQu4TpU6",
...
wallet successfully created, file location is wallets/neofs1.json

Transfer GAS from wallets/wallet.json. The password is empty.

$ neo-go wallet nep17 transfer \
    -w wallets/wallet.json \
    -r http://main-chain.neofs.devenv:30333 \
    --from NbUgTSFvPmsRxmGeWpuuGeJUoRoi6PErcM \
    --to NXnzw3J9VvKXjM1BPAJK4QUpTtEQu4TpU6 \
    --amount 50 \
    --token GAS

Check it's there.

$ neo-go wallet nep17 balance \
    -w wallets/neofs1.json \
    -r http://main-chain.neofs.devenv:30333

Claim GAS from consensus node

If there is no enough GAS on wallets/wallet.json account, you can claim some GAS to consensus node's wallet and then transfer it.

Consensus node is running with services/chain/node-wallet.json wallet. It has multiple accounts with the password one.

Claim GAS to consensus node's wallet. Use account that contains NEO tokens.

$ neo-go wallet claim \
    -w services/chain/node-wallet.json \
    -r http://main-chain.neofs.devenv:30333 \
    -a NfgHwwTi3wHAS8aFAN243C5vGbkYDpqLHP \
Password >
70e09bbd55846dcc7cee23905b737c63e5a80d32e387bce108bc6db8e641fb90

Then you can transfer GAS the same way as it was done in previous section.

$ neo-go wallet nep17 transfer \
    -w services/chain/node-wallet.json \
    -r http://main-chain.neofs.devenv:30333 \
    --from NfgHwwTi3wHAS8aFAN243C5vGbkYDpqLHP \
    --to NXnzw3J9VvKXjM1BPAJK4QUpTtEQu4TpU6 \
    --amount 50 \
    --token GAS

NeoFS GAS deposit

NeoFS identifies users by their Neo wallet key pair. To start using NeoFS in devenv you need to transfer some GAS to NeoFS contract in main chain.

Invoke bin/deposit.sh script by running make prepare.ir command to transfer 50 GAS from account in wallets/wallet.json file. Script enters passwords automatically with expect utility.

$ make prepare.ir 
Password > 
Can't find matching token in the wallet. Querying RPC-node for balances.
6713c776f4102300691d9c3c493bcd3402434f5e32e8147e0a5bc72209a1e410

Script converts addresses and executes this command:

$ neo-go wallet nep17 transfer \
    -w wallets/wallet.json \
    -r http://main-chain.neofs.devenv:30333 \
    --from NbUgTSFvPmsRxmGeWpuuGeJUoRoi6PErcM \
    --to NerhjaqJsJt4LxMqUbkkVMpsF2d9TtcpFv \
    --token GAS \
    --amount 50

You can specify any wallet address scripthash in the transfer's data argument, and NeoFS deposit will be transferred to that address.

$ neo-go wallet nep17 transfer \
    -w wallets/wallet.json \
    -r http://main-chain.neofs.devenv:30333 \
    --from NbUgTSFvPmsRxmGeWpuuGeJUoRoi6PErcM \
    --to NerhjaqJsJt4LxMqUbkkVMpsF2d9TtcpFv \
    --token GAS \
    --amount 50 \
