Steps

​
1. Ensure the wallet is funded

The sub-account’s legend_wallet_address must hold the asset you want to earn with. Transfer USDC (or another supported asset) to this address on the target network before creating a plan.

​
2. Create the earn plan

const plan = await client.plan.earn(account.external_id, {
  amount: "1000000",   // 1 USDC
  asset: "USDC",
  network: "base",
  protocol: "compound",
});

​
3. Sign and execute

See the Plan-Sign-Execute concept guide for the full signing flow. 
const signer = privateKeyToAccount(privateKey);
const signature = await signer.sign({ hash: plan.chart.eip712_data.digest });

const result = await client.plan.execute(account.external_id, {
  planId: plan.plan_id,
  signature,
});

​
4. Monitor

Poll activities to confirm the deposit: 
const { activities } = await client.accounts.activities(account.external_id);
// Look for activity_type: "quark_operation_executed"
// with activity_metadata containing action_type: "COMET_SUPPLY"
