Overview

When you deposit USDC or USDT into C0, your balance earns yield from the underlying M token rate. The yield estimate endpoint provides projections based on your current C0 balance and the live on-chain rate.

​
How Yield Works

  1. You deposit USDC or USDT and receive C0
  2. C0 accrues yield from the M token earner rate (continuous compounding)
  3. The gross APY is converted to a net APY after a 10% platform fee
  4. Your C0 balance grows over time as yield accrues

​
1. Get Yield Estimate

Fetch yield projections for a wallet’s C0 balance: 
const chainId = 1;
const address = '0x742d35cc6634c0532925a3b844bc454e4438f44e';

const response = await fetch(
  `https://api.caminotreasury.com/v1/${chainId}/yield?address=${address}`,
  { headers: { 'x-api-key': 'your-api-key' } }
);

const { earning, decimals, rate, dailyYield, monthlyYield, annualYield } =
  await response.json();

// {
//   "earning": "5000000000",
//   "decimals": 6,
//   "rate": { "apy": 0.03047 },
//   "dailyYield": "417",
//   "monthlyYield": "12500",
//   "annualYield": "152373"
// }

2. Interpreting the Response

All values are in raw C0 units with 6 decimal places. To convert to human-readable amounts: 
const balance = Number(earning) / 10 ** decimals;
const daily = Number(dailyYield) / 10 ** decimals;
const monthly = Number(monthlyYield) / 10 ** decimals;
const annual = Number(annualYield) / 10 ** decimals;

console.log(`C0 Balance: ${balance.toFixed(2)}`);
console.log(`APY: ${(rate.apy * 100).toFixed(2)}%`);
console.log(`Daily:   ${daily.toFixed(6)}`);
console.log(`Monthly: ${monthly.toFixed(6)}`);
console.log(`Annual:  ${annual.toFixed(6)}`);
Yield projections are based on the current C0 balance and the live on-chain M token rate. If the rate or balance changes, projections will update accordingly.

​
3. Tracking Yield Over Time

You can track how your C0 balance grows by polling the balances endpoint periodically: 
async function trackYield(chainId, address, apiKey) {
  const headers = { 'x-api-key': apiKey };

  // Get current C0 balance
  const balanceRes = await fetch(
    `https://api.caminotreasury.com/v1/${chainId}/balances/${address}`,
    { headers }
  );
  const { data: balances } = await balanceRes.json();
  const c0 = balances.find(b => b.symbol === 'C0');

  // Get yield estimate
  const yieldRes = await fetch(
    `https://api.caminotreasury.com/v1/${chainId}/yield?address=${address}`,
    { headers }
  );
  const estimate = await yieldRes.json();

  return {
    balance: Number(c0.raw) / 10 ** c0.decimals,
    apy: estimate.rate.apy,
    monthlyYield: Number(estimate.monthlyYield) / 10 ** estimate.decimals
  };
}
Compare snapshots over time to see actual yield accrual — as yield accrues, your C0 balance will increase, and so will the projected yields.
