We've created a testnet version of our website where you can test our dapp with the contracts that we will deploy on mainnet.
Link to dapp testnet : https://testnet.hermesfinance.app/
If you need any AVAX on testnet use this faucet : https://faucet.avax-test.network/
When requesting AVAX on testnet, remove the "0x" of your addresse because it can create some unknown bugs into faucet.
