# Example Usage

## Remote Signing

The below example code displays the usage of `customSigner` to remotely sign a transaction that was generated by Anchor Earn.

For demonstration purposes, implementation of `customSigner` was done using Terra.js. For real usage `customSigner` should be connected with a remote signing solution used by the integrator (e.g. Ledger Hardware Wallet, Custodian APIs).

```javascript
const anchorEarn = new AnchorEarn({
  chain: CHAINS.TERRA,
  network: NETWORKS.BOMBAY_12,
  mnemonic:
    '...',
});

// customSigner signs the generated unsigned tx
const customSigner = async (tx: Msg[]) => {
  const account = new MnemonicKey({
  mnemonic:
    '...',
  });

  const wallet = new Wallet(
    new LCDClient({
      URL: 'https://bombay-lcd.terra.dev',
      chainID: 'bombay-12',
    }),
    account,
  );

  return await wallet.createAndSignTx({
    msgs: tx,
    gasAdjustment: 2,
    gasPrices: { uusd: 0.15 },
  });
};

await anchorEarn.deposit({
  amount: '0.01',
  currency: DENOMS.UST,
  log: (data) => {
    console.log(data);
  },
  customSigner: customSigner,
});
```

## Remote Signing & Broadcasting

The below example code displays the usage of `customBroadcaster` to remotely sign and broadcast a transaction that was generated by Anchor Earn.

For demonstration purposes, implementation of `customBroadcaster` was done using Terra.js. For real usage `customBroadcaster` should be connected with a remote signing solution used by the integrator (e.g. Web Wallet Extension).

```javascript
const anchorEarn = new AnchorEarn({
  chain: CHAINS.TERRA,
  network: NETWORKS.BOMBAY_12,
  mnemonic:
    '...',
});

// customBroadcaster signs and broadcasts the generated unsigned tx
const customBroadcaster = async (tx: Msg[]) => {
  const lcd = new LCDClient({
    URL: 'https://bombay-lcd.terra.dev',
    chainID: 'bombay-12',
  });

  const wallet = new Wallet(
    lcd,
    new MnemonicKey({
    mnemonic:
      '...',
    }),
  );

  const signedTx = await wallet.createAndSignTx({
    msgs: tx,
    gasAdjustment: 2,
    gasPrices: { uusd: 0.15 },
  });

  return lcd.tx.broadcastSync(signedTx).then((result) => {
    return result.txhash;
  });
};

await anchorEarn.withdraw({
  amount: '0.01',
  currency: DENOMS.AUST,
  log: (data) => {
    console.log(data);
  },
  customBroadcaster: customBroadcaster
});
```

## Logging Transaction Progress

The below example code displays the usage of `loggable` to check on request progresses that were generated by Anchor Earn.

```javascript
const deposit = await anchorEarn.deposit({
  amount: '...',
  currency: DENOMS.UST,
  log: (data) => {
    console.log(data);
  }
});
```
