The bridge between Dune Network and your browser

A Secure Wallet

Metal offers an interface to the Dune Network blockchain. It allows anyone to execute operations like sending coins, picking a delegation service and delegating coins to them, originating new smart contract, etc. This enables anyone to interact with the blockchain without having to run a full node.

A Bridge to dApps

Metal aims to create a hub that will help dApp developers and remove friction for the users. DApp developers can start working on their app and use the injected Metal API and not worry about the wallet/crypto by delegating it to Metal. Users will receive notification of any signing requests coming from the visited dApp pages and decide to accept or not.

Open Source and Free

You can install it from the extension store on Firefox and Chrome. You can view the source code on GitLab. You can also use gitlab to contribute to the code base by making merge requests or reporting any issues that you may encounters.

Simplifying dApp Development

/* Call Metal that will handle the transaction for you */
metal.send({
  /* The destination address */
  dst: "dn1NxT6WVYeAqrUfKBAgfWSk5VRoSbx8z7WF",
  /* The amount that you want to transfer in mudun, e.g. 42 DUN */
  amount: "42000000",
  /* The callback is optional, e.g. let's display the operation hash */
  cb: (res => console.log(res.msg))
});

One line transactions in your dApps

Metal handles the transaction for the dApp developers. It forges and ask for user to sign the transaction before sending it onto the blockchain.

Read The Documentation

/* The initial balance of your smart contract in mudun,
   e.g. for 100 DUN */
var initial_balance = "100000000";

/* The callback is optional, e.g. let's display the
   operation hash */
var callback = (res => console.log(res.msg)) ;

/* Call Metal that will handle the transaction for you */
metal.originate({balance:initial_balance,
                 sc_storage:'YOUR_INITIAL_STORAGE',
                 sc_code: 'YOUR_SMART_CONTRACT_CODE',
                 cb: callback}) ;
