Bank of Staked is an EOS smart contract aiming to provide cheap CPU&NET lease to both EOS users and developers. This contract is build by EOSLaoMao Team.
The UX Bank of Staked wants to achieve is that any account could get CPU&NET delegated automatically through a simple transfer, no more action needed. And the undelegate process will also be triggered automatically.
The main logic of Bank of Staked are realized through these three tables:
Plan table holds all available plans user can choose, main fields are:
price asset; //plan price
cpu asset; // delegated cpu this plan offers.
net asset; // delegated net this plan offers.
duration unit64; //the period of time service gonna last, in minutes.
is_free uint64; //free plan or not, if is_free is 1, order will be auto refunded.
...
Creditors are the real ones who delegate&undelegate. When a valid transfer happens, the contract will try to find is_active creditor to do an auto delegation using that creditor account.
account account_name;
is_active uint64;
...
is_active indicates if this creditor is ready to delegate or not.
in production, you should always have creditors shifting like 3 days in a roll, so that non-active creditors have time to get their undelegated token back.
Order table consists of active order records, by active, we mean these orders are not expired.
buyer account_name;
creditor account_name;
beneficiary account_name;
cpu_staked asset;
net_staked asset;
expire_at uint64;
...
buyer is the account who did the actual transfer in the first place, if any refund happens, token will be refunded to buyer account also.
beneficiary is the actual account who get cpu and net delegated. buyer can specify this account in transfer memo if he/she like.
creditor is the account who did delegation.
cpu_staked and net_staked is cpu&net delegated in this order.
expire_at is when this order will expire. After order expired, order record will be deleted from Order Table.
There are also several other tables facilitating this contract. such as,
freelock table, used to lock free plan for each account for 24 hours.
history table, used to store meta data of deleted expired order.
blacklist, used to blacklist certain account from using bankofstaked contract.
We have deployed it on Mainnet:
https://www.myeoskit.com/#/tx/bankofstaked
Query plan table to get available plans:
cleos -u https://api1.eosasia.one get table bankofstaked bankofstaked plan
{
"rows": [{
"id": 0,
"price": "0.1000 EOS",
"is_free": "1",
"cpu": "1.0000 EOS",
"net": "0.0000 EOS",
"duration": 60,
"created_at": 1535965927,
"updated_at": 1535965927
},
],
"more": false
}
price indicates the EOS you should transfer to bankofstaked to get certain cpu and net for duration minutes.
is_free means if you can get a refund or not(is refund applied, it will happend immediately!!)
Currently we only provide 1 FREE plan: 0.1 EOS for 60 min of 1 EOS CPU staked, you will get a 0.1 EOS refund immediately after you transfer.
Will add more plans ASAP.
Currently, you can transfer 0.1 EOS to bankofstaked to get 1 EOS staked for cpu for 60 minutes.
NOTE: bankofstaked will automatically return the token you transfered back to you immediately.
cleos -u https://api1.eosasia.one transfer YOUR_ACCOUNT bankofstaked "0.1 EOS" -p YOUR_ACCOUNT@active
After transfering token, you will be delegated 1 EOS of CPU to you , after 60 minutes, it will undelegate automatically using deferred transaction.
if you want to contribute your EOS to creditor fund(only delegate, no transfer needed), or if you are a BP who are willing to help users and developers, please contact us at: contact@eoslaomao.com
