Deploy eosio.assert Doc

Prerequisites

1. Build eosio.assert smart contract

Use eosio.cdt 1.6.1 to build eosio.assert smart contract, the build is in contracts/eosio.assert folder.

checksums:

openssl dgst -sha256 contracts/eosio.assert.wasm
SHA256(contracts/eosio.assert.wasm)= 2f1e6ca484eeb88d4c0102a90279dc320edf58e3853784101760530be77f60a2

openssl dgst -sha256 contracts/eosio.assert.abi
SHA256(contracts/eosio.assert.abi)= 92807134f93622ab1ffaf16ac1688658688394155f5838f61b648f28bd01769b

2. Prepare chain id, name and logo

You can find the logo of Crypto Kylin Testnet under public folder, the checksum is:

openssl dgst -sha256 public/CryptoKylin-logo.png
SHA256(public/CryptoKylin-logo.png)= 7d0b4735cf3788d38b972b383a80acb56f97955a50dee022e9b976eca282f754

the chain id of Crypto Kylin Testnet is 5fff1dae8dc8e2fc4d5b23b2c7665c97f9e9d8edf2b6485a86ba311c25639191, you can find it via api nodes, such as https://api-kylin.eoslaomao.com/v1/chain/get_info

STEP 1/3: Create account eosio.assert

Prepare create account multisig transaction and propose

1. create eosio.assert account :

cleos -u https://api-kylin.eoslaomao.com push action eosio newaccount '{"creator":"eosio","name":"eosio.assert","owner":{"threshold":1,"keys":[],"accounts":[{"permission":{"actor":"eosio","permission":"active"},"weight":1}],"waits":[]},"active":{"threshold":1,"keys":[],"accounts":[{"permission":{"actor":"eosio","permission":"active"},"weight":1}],"waits":[]}}' -p eosio -s -j -d > create_assert.json

2. delegate bandwidth to eosio.assert:

cleos -u https://api-kylin.eoslaomao.com system delegatebw eosio eosio.assert "10 EOS" "10 EOS" -p eosio -s -j -d >> create_assert.json

3. buyram for eosio.assert:

cleos -u https://api-kylin.eoslaomao.com system buyram eosio eosio.assert "10 EOS" -p eosio -s -j -d >> create_assert.json

Merge actions in file create_assert.json, also change expire time in create_assert.json into future date, e.g. 10 days later.

You will get a transaction like this:

{
  "expiration": "2019-06-15T11:36:47",
  "ref_block_num": 0,
  "ref_block_prefix": 0,

    },{
      "account": "eosio",
      "name": "buyram",
      "authorization": [{
          "actor": "eosio",
          "permission": "active"
        }
      ],
      "data": "0000000000ea305590afc2d800ea3055a08601000000000004454f5300000000"
    }

}

We have proposed this transaction on Kylin Testnet : https://kylin.eosx.io/tools/msig/proposal?proposer=eoslaomaocom&name=createassert, please review and verify ASAP.

cleos -u https://api-kylin.eoslaomao.com multisig review eoslaomaocom createassert

The actual transaction used in this proposal is in file create_assert.json.

STEP 2/3: Deploy eosio.assert contract

cleos -u https://api-kylin.eoslaomao.com set contract eosio.assert > deploy_assert.json

Update expiration to a future time, set ref_block_num and ref_block_prefix to 0, and propose it.

STEP 3/3: Setup chain info

Now we need to call setchain action in eosio.assert contracts to register Kylin Testnet onchain.

Here is the payload:

{
      "chain_id": "5fff1dae8dc8e2fc4d5b23b2c7665c97f9e9d8edf2b6485a86ba311c25639191",
      "chain_name": "CryptoKylin Testnet",
      "icon": "7d0b4735cf3788d38b972b383a80acb56f97955a50dee022e9b976eca282f754"
}

cleos push action eosio.assert setchain {"chain_id": "5fff1dae8dc8e2fc4d5b23b2c7665c97f9e9d8edf2b6485a86ba311c25639191","chain_name": "CryptoKylin Testnet","icon": "7d0b4735cf3788d38b972b383a80acb56f97955a50dee022e9b976eca282f754"} -p eosio -s -j -d > setup_assert.json

Update setup_assert.json, set expiration to a future time, set ref_block_num and ref_block_prefix to 0, and propose it.
