CORS policy problem

[stephane303]

When I try to connect my wallet it doesn't work and see this in the console:
Access to XMLHttpRequest at 'https://api.coinmarketcap.com/data-api/v1/farming/yield/latest' from origin 'https://yieldfarmingtools.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. b1c7e46c61a1f7c247cc66701dd3fb140f85194c.0244ad4d637252ec62e0.js:1 Error: Network Error at LYNF.e.exports (2c33f15ee62acfe8da3fc8f8ef84c026a020e16f.bf028d44d9aa4e16f235.js:1) at XMLHttpRequest.p.onerror (2c33f15ee62acfe8da3fc8f8ef84c026a020e16f.bf028d44d9aa4e16f235.js:1) (anonymous) @ b1c7e46c61a1f7c247cc66701dd3fb140f85194c.0244ad4d637252ec62e0.js:1 api.coinmarketcap.com/data-api/v1/farming/yield/latest:1 Failed to load resource: net::ERR_FAILED yieldfarmingtools.com/:1 Access to fetch at 'https://etherchain.org/api/basic_stats' from origin 'https://yieldfarmingtools.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

This is an issue on Etherchain's behalf. They are not using CORS in their API implementation.

In the meantime the solution is to use another API for gas prices.
