-# N3 main chain privnet service
-
-A single-node N3 privnet deployment, running on
-[neo-go](https://github.com/nspcc-dev/neo-go). Represents N3 MainNet.
-
-Contracts deployed:
-- FrostFS [contract](https://github.com/TrueCloudLab/frostfs-contract/tree/master/neofs)
-- Processing [contract](https://github.com/TrueCloudLab/frostfs-contract/tree/master/processing)
-
-RPC available at `http://main-chain.frostfs.devenv:30333`.
-
-## .env settings
-
-### CHAIN_URL
-
-URL to get main chain dump. Used on artifact get stage.
-
-### CHAIN_PATH
-
-Path to get main chain dump. If set, overrides `CHAIN_URL`.
-
-### NEOGO_VERSION
-
-Version of neo-go docker container for main chain deployment.
-
-## 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.frostfs.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 FrostFS contract), you can transfer GAS from there.
-
-1. Create new wallet.
-
-```
-$ neo-go wallet init -a -w wallets/frostfs1.json
-
-Enter the name of the account > frostfs1
-Enter passphrase >
-Confirm passphrase >
-
-{
-    "version": "3.0",
-    "accounts": [
-        {
-            "address": "NXnzw3J9VvKXjM1BPAJK4QUpTtEQu4TpU6",
-...
-wallet successfully created, file location is wallets/frostfs1.json
-```
-
-2. Transfer GAS from `wallets/wallet.json`. The password is empty.
-
-```
-$ neo-go wallet nep17 transfer \
-    -w wallets/wallet.json \
-    -r http://main-chain.frostfs.devenv:30333 \
-    --from NbUgTSFvPmsRxmGeWpuuGeJUoRoi6PErcM \
-    --to NXnzw3J9VvKXjM1BPAJK4QUpTtEQu4TpU6 \
-    --amount 50 \
-    --token GAS
-```
-
-3. Check it's there.
-
-```
-$ neo-go wallet nep17 balance \
-    -w wallets/frostfs1.json \
-    -r http://main-chain.frostfs.devenv:30333
-
-Account NXnzw3J9VvKXjM1BPAJK4QUpTtEQu4TpU6 
-GAS: GasToken (d2a4cff31913016155e38e474a2c06d08be276cf)
-        Amount : 50
-        Updated: 14689
-```
-
-## 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.frostfs.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.frostfs.devenv:30333 \
-    --from NfgHwwTi3wHAS8aFAN243C5vGbkYDpqLHP \
-    --to NXnzw3J9VvKXjM1BPAJK4QUpTtEQu4TpU6 \
-    --amount 50 \
-    --token GAS
-```
-
-## FrostFS GAS deposit
-
-FrostFS identifies users by their Neo wallet key pair. To start using FrostFS in
-devenv you need to transfer some GAS to FrostFS 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.frostfs.devenv:30333 \
-    --from NbUgTSFvPmsRxmGeWpuuGeJUoRoi6PErcM \
-    --to NerhjaqJsJt4LxMqUbkkVMpsF2d9TtcpFv \
-    --token GAS \
-    --amount 50
-```
-
-You can specify any wallet address scripthash in the transfer's data argument,
-and FrostFS deposit will be transferred to that address.
-
-```
-$ neo-go wallet nep17 transfer \
-    -w wallets/wallet.json \
-    -r http://main-chain.frostfs.devenv:30333 \
-    --from NbUgTSFvPmsRxmGeWpuuGeJUoRoi6PErcM \
-    --to NerhjaqJsJt4LxMqUbkkVMpsF2d9TtcpFv \
-    --token GAS \
-    --amount 50 \
-    hash160:bd711de066e9c2f7b502c7f3f0e0a6f1c8341edd
