Smart WBTC yield automation on Starknet. Deposit once, earn more through intelligent rebalancing across vesuxyz & EkuboProtocol
YieldStark is a non-custodial yield optimizer that intelligently allocates Bitcoin (WBTC) into the most profitable DeFi opportunities across the Starknet ecosystem. Built with Next.js and Starknet, it provides a seamless experience for BTC holders to earn yield directly on their assets.
Bitcoin holders looking to earn yield face several significant roadblocks:
-Lack of Native Yield Options
-Yield strategies are spread across multiple protocols, requiring manual research bridging, and tracking.
-Navigating yield farming, bridging, and gas optimization is too technical for the typical BTC holder.
YieldStark solves the complexity of earning BTC-native yield through three core components:
-
AI-Powered Yield Engine -Real-time APY tracking across BTC strategies -Predictive modeling for optimal rebalancing -Risk-adjusted portfolio rotation
-
Automated Smart Execution -Non-custodial BTC deposits into top-performing pools -Rebalancing and compounding based on performance data -Auto-conversion of rewards into BTC
-
Pragma Data Integration -On-chain APY feeds for BTC strategies -Real-time pool metrics and risk signals -Decentralized and verifiable price + yield data
import { VesuOracleService } from "../services/vesuOracle";
import { EkuboOracleService } from "../services/ekuboOracle";
export async function decideBestProtocol() {
const vesuAPY = await VesuOracleService.getInstance().calculateAPY();
const ekuboAPR = await EkuboOracleService.getInstance().calculateAPR();
return vesuAPY > ekuboAPR ? "vesu" : "ekubo";
}
// Usage:
// const best = await decideBestProtocol();
// // Use `best` to allocate funds accordingly┌────────────────────┐ ┌────────────────────┐ ┌────────────────────┐
