[eborrallo]

Get Markers functionality to return all the markets active on the protocol satisfying the next type

Array< MarketParams>

The solidity code to populate this array is the next one

 function getMarkets(MgvReader reader) public view returns (MarketWithToken[] memory) {
        (Market[] memory markets,) = reader.openMarkets();
        uint numMarkets = markets.length;
        MarketWithToken[] memory marketsWithToken = new MarketWithToken[](numMarkets);

        for (uint i = 0; i < numMarkets;) {
            IERC20 token0 = IERC20(markets[i].tkn0);
            IERC20 token1 = IERC20(markets[i].tkn1);

            marketsWithToken[i] = MarketWithToken({
                tkn0: Token({
                token: address(token0),
                decimals: token0.decimals(),
                symbol: token0.symbol()
            }),
                tkn1: Token({
                token: address(token1),
                decimals: token1.decimals(),
                symbol: token1.symbol()
            }),
            adr:
                tickSpacing: markets[i].tickSpacing
            });

            unchecked {
                i++;
            }
        }

        return marketsWithToken;
    }

The code was compiled and used as a bytecode
