WebYou initiate an on-chain request by calling a function in an oracle contract and send a payment in LINK. The oracle node sees the on-chain request. The node sends an HTTP query to the URL specified in your request and gets the response data. The node then calls a "callback" function in the oracle contract with the data from the API. WebThe Polygon class encapsulates a description of a closed, two-dimensional region within a coordinate space. This region is bounded by an arbitrary number of line segments, each of which is one side of the polygon. Internally, a polygon comprises of a list of (x,y) coordinate pairs, where each pair defines a vertex of the polygon, and two successive pairs are the …

Web3 Answers. If you're intending to use Oracle Spatial for storage or processing of polygons, then you'll need to store the data as an SDO_GEOMETRY object. Here's a quick example: CREATE TABLE my_polygons ( id INTEGER , polygon sdo_geometry ) / INSERT INTO my_polygons ( id , polygon ) VALUES ( 1 , sdo_geometry ( 2003 -- 2D Polygon , 4326 -- … WebFeb 14, 2024 · Uniswap oracles can be very useful, but they can also be quite risky. Bad actors can manipulate the price in the uniswap pool if the liquidity is low enough, then exploit your protocol using the manipulated price.
