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).
1
const anchorEarn = new AnchorEarn({
2
  chain: CHAINS.TERRA,
3
  network: NETWORKS.BOMBAY_12,
4
  mnemonic:
5
    '...',
6
});
7
​
8
// customSigner signs the generated unsigned tx
9
const customSigner = async (tx: Msg[]) => {
10
  const account = new MnemonicKey({
11
  mnemonic:
12
    '...',
13
  });
14
​
15
  const wallet = new Wallet(
16
    new LCDClient({
17
      URL: 'https://bombay-lcd.terra.dev',
18
      chainID: 'bombay-12',
19
    }),
20
    account,
21
  );
22
​
23
  return await wallet.createAndSignTx({
24
    msgs: tx,
25
    gasAdjustment: 2,
26
    gasPrices: { uusd: 0.15 },
27
  });
28
};
29
​
30
await anchorEarn.deposit({
31
  amount: '0.01',
32
  currency: DENOMS.UST,
33
  log: (data) => {
34
    console.log(data);
35
  },
36
  customSigner: customSigner,
37
});

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).
1
const anchorEarn = new AnchorEarn({
2
  chain: CHAINS.TERRA,
3
  network: NETWORKS.BOMBAY_12,
4
  mnemonic:
5
    '...',
6
});
7
​
8
// customBroadcaster signs and broadcasts the generated unsigned tx
9
const customBroadcaster = async (tx: Msg[]) => {
10
  const lcd = new LCDClient({
11
    URL: 'https://bombay-lcd.terra.dev',
12
    chainID: 'bombay-12',
13
  });
14
​
15
  const wallet = new Wallet(
16
    lcd,
17
    new MnemonicKey({
18
    mnemonic:
19
      '...',
20
    }),
21
  );
22
​
23
  const signedTx = await wallet.createAndSignTx({
24
    msgs: tx,
25
    gasAdjustment: 2,
26
    gasPrices: { uusd: 0.15 },
27
  });
28
​
29
  return lcd.tx.broadcastSync(signedTx).then((result) => {
30
    return result.txhash;
31
  });
32
};
33
​
34
await anchorEarn.withdraw({
35
  amount: '0.01',
36
  currency: DENOMS.AUST,
37
  log: (data) => {
38
    console.log(data);
39
  },
40
  customBroadcaster: customBroadcaster
41
});

Logging Transaction Progress
The below example code displays the usage of loggable to check on request progresses that were generated by Anchor Earn.
1
const deposit = await anchorEarn.deposit({
2
  amount: '...',
3
  currency: DENOMS.UST,
4
  log: (data) => {
5
    console.log(data);
6
  }
7
});
