Introduction

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

delegate token to validator, get result

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

{% hint style="info" %} only can delegate origin token {% endhint %}

{% hint style="info" %} only delegate validator who has participated in block generation, delegate again, will get reward {% endhint %}

delegate event

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

undelegate token from validator, get result

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

undelegate event

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

redelegate token from validator to other validator, get result

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

redelegate event

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