Yield Booster Calculator

WHAT IT DOES

Yield Booster Calculator gives DeFi stakers, yield farmers, and protocol analysts real-time insight into boosted staking yields. It reads live on-chain data including staking contract state, yield booster contract state, user staked balances, booster multipliers, reward rates, total rewards, and user positions. You can calculate base APR, boosted APR, effective multiplier, and projected yields on daily, monthly, and yearly timeframes. The tool shows you in real time how much extra yield you earn from booster contracts, what your effective multiplier is, and how your boosted yield compares to base yield—so you can make informed decisions about where to stake and whether booster programs are worth participating in.

HOW TO USE

Connect your EVM wallet (optional—the tool can work in read-only mode with a manually entered address). Enter the staking contract address and the yield booster contract address. Provide a user address to analyze (defaults to your connected wallet). Click "Calculate boosted yield" to fetch current data from the chain. The tool displays the user's staked balance, base APR, booster multiplier, boosted APR, daily/monthly/yearly boosted yields, and boost factor (how many times base yield is multiplied). A visual dashboard shows the APR comparison and yield projections with progress bars. All data is read directly from the contracts—no assumptions or simulations.

TECHNICAL APPROACH

This tool queries live contract state using ethers v5.7.2. It calls balanceOf() and rewardRate() on the staking contract to get the user's staked balance and current reward rate. It calls getMultiplier(), getBoostedBalance(), baseAPR(), and maxMultiplier() on the booster contract to compute the effective multiplier and boosted APR. If the booster contract doesn't expose standard multiplier functions, the tool falls back to computing the multiplier from the boosted balance divided by the staked balance. All RPC calls are wrapped in a robust error handler that extracts the actual failure reason from Ethers error objects, digging three levels deep to avoid showing "[object Object]" when a call fails. APR is calculated from the reward rate and total staked, then multiplied by the booster multiplier to compute boosted APR. Yield projections are derived from the boosted APR and the user's staked balance.

WHAT IT CANNOT SEE

This tool cannot predict future yield rates, user behavior, or market conditions. It cannot account for off-chain boost parameters or changes not recorded on-chain. It cannot detect whether a booster contract is legitimately implemented or whether it will continue to apply the same multipliers. It cannot simulate execution or test whether the booster will maintain its current multiplier over time. It cannot see pending staking operations that are not yet broadcast to the public mempool. It cannot detect changes in total staked that affect APR calculations between blocks. The tool calculates yields based on current state, but it does not guarantee that yields will remain constant or that booster multipliers will not change.

PLEASE NOTE

This tool supports EVM‑compatible chains only (Ethereum, Goerli, Sepolia, Arbitrum, Optimism, Polygon). Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, and XRP are not supported. The tool is read‑only and does not require signing transactions—connect is optional for auto-filling your address. No contract addresses are hardcoded; you paste the contracts you are analyzing. The tool is free and open under the BotGentz PLAYBOOK‑C specification.
