Memento DFM is a multi-chain asset management protocol that allows users to create, mint, and manage ETF-style tokenized funds. You can check our documentation at https://domanifinance.notion.site/DOMANI-DAO-Wiki-eee68e859018473f9e624d711fcbd242.
The dedicated environment to test the Memento DFM dApp (decentralized app) is reachable at https://bug-bounty-dfm.mementoblockchain.com.
It is recommended to use the Metamask wallet when connecting.
No VPN allowed.
Use a desktop (the Memento DFM dApp is not mobile friendly).
No registration is required, just connect your crypto wallet to the Memento DFM dApp (using the testnet blockchains).
In order to connect to the dApp, you need a crypto wallet like Metamask (https://metamask.io/) or Rabby (https://rabby.io/).
This is a test environment, pointing to testnet blockchains, and only test tokens (i.e. not real tokens) are required to execute transactions and perform tests.
In order to execute transactions, you need test tokens in one of these testnets: Ethereum Sepolia, ZKsync Era Sepolia, Avalanche Fuji, Polygon Amoy, Kaia Kairos. The test tokens can be obtained for free from any of the faucets available online.
