Introduction

use staking v2 precompiled contract to call some functions of the staking module, such as: delegate, undelegate, redelegate, etc.

Method

delegateV2

delegate token to validator, get result

function delegateV2(
    string memory _val,
    uint256 _amount
) external returns (bool _result);

• _val: the validator address

• _amount: the amount of the token to be delegate

• _result_: the delegate result

only can delegate origin token

only delegate validator who has participated in block generation, delegate again, will get reward

delegate event

event DelegateV2(
    address indexed delegator,
    string validator,
    uint256 amount
);

• delegator: the delegator address

• validator: the validator address to be delegated

• amount: the amount of the token to be delegated

undelegateV2

undelegate token from validator, get result

function undelegateV2(
    string memory _val,
    uint256 _amount
) external returns (bool _result);

• _val: the validator address to be undelegate

• _amount: the amount to undelegate

• _result_: the undelegate result

undelegate event

event UndelegateV2(
    address indexed sender,
    string validator,
    uint256 amount,
    uint256 completionTime
);

• sender: the sender address

• validator: the validator address to be undelegate

• amount: the amount to undelegate

• completionTime: the completion time of undelegate

redelegateV2

redelegate token from validator to other validator, get result

function redelegateV2(
    string memory _valSrc,
    string memory _valDst,
    uint256 _amount
) external returns (bool _result);

• _valSrc: the validator address to be redelegate

• _valDst: the validator address to be redelegate to

• _amount: the amount to redelegate

• _result_: the undelegate result

redelegate event

event RedelegateV2(
    address indexed sender,
    string valSrc,
    string valDst,
    uint256 amount,
    uint256 completionTime
);

• sender: the sender address

• valSrc: the validator address to be redelegated

• valDst: the validator address to be redelegated to

• amount: the amount to redelegate

• completionTime: the completion time of redelegate
