Voting

Vote/Unvote

Token : vevc
op type : Vote(0x03)
Interacting pool = gauge address

Vote interacts with gauge. Gauge is same with pool address for volatile pairs. Check Staketo know how to get stable pool's gauge address.

Use positive amount to vote and negetive amount to unvote.

// you vote with vevc token which is ERC20 not ERC721
Token[] memory tokens = new Token[](1);
tokens[0] = toToken(IERC20(vevc));

VelocoreOperation[] memory ops = new VelocoreOperation[](1);
// Vote interacts with gauge. Gauge is same with pool for volatile pairs.
// Check Stake section of the docs to find out way to get stablepool's gauge address.
int128 voteAmount = int128(int256(IERC20(vevc).balanceOf(address(this))));
ops[0].poolId = toPoolId(VOTE,usdc_eth_pool);
ops[0].tokenInformations = new bytes32[](1);
//Vote : positive flow in gauge's perspective. Unvote : negative flow. so just put - in the amount to unvote.
ops[0].tokenInformations[0] = toTokenInfo(0x00,EXACTLY,voteAmount);        
ops[0].data = "";
return execute(tokens, new int128[](1), ops);

Harvesting vote reward

If the gauge has already been voted on, there will be a voting reward to claim.

In this case, you'll also need to send additional tokenInfo in the Op to claim it. If you don't, it will be credited to your internal balance and you can claim it later by performing a separate claim operation.

Token : Since voting rewards are accumulated in the LP itself, you need to include the pool LP address.
opType : VOTE(0x03)
Interacting pool : gauge address
use AT_MOST 0 for amount since you are receiving.

// Same as vote. just lp token is added on the operation. 
// If you are not changing the vote, just send lp token operation without vevc.
Token[] memory tokens = new Token[](2);
tokens[0] = toToken(IERC20(vevc));
tokens[1] = toToken(IERC20(usdc_eth_pool));

VelocoreOperation[] memory ops = new VelocoreOperation[](1);
int128 voteAmount = int128(int256(IERC20(vevc).balanceOf(address(this))));
ops[0].poolId = toPoolId(VOTE,usdc_eth_pool);
// this part is added. send 2 tokenInformation instead of 1.
ops[0].tokenInformations = new bytes32[](2);
ops[0].tokenInformations[0] = toTokenInfo(0x00,EXACTLY,voteAmount); 
// Since you don't know how many tokens you will claim, but you are sure that you are receiving, not giving, 
// so use AT_MOST 0 for the LP token amount.
ops[0].tokenInformations[1] = toTokenInfo(0x01,AT_MOST,0);        
ops[0].data = "";

return execute(tokens, new int128[](1), ops);
