Bonded Finance

🧬 Project Name: Bonded Finance

Unlock your future yield, today.

Summary

Bonded Finance is a new DeFi protocol built on Starknet that enables users to sell their future yield for instant liquidity — or buy discounted future returns for boosted profits at maturity.

Instead of locking capital and waiting weeks or months for rewards, Bonded Finance turns yield into a tradable asset — unlocking new DeFi use cases.

Problem

In today’s DeFi landscape, yield is slow and rigid. Users who stake assets or participate in incentive programs must wait for distribution, often weekly or monthly. During this time, their capital is frozen — limiting flexibility and financial creativity.

This issue is particularly visible with DeFi Spring, Starknet Foundation’s incentive program, where users receive weekly rewards but can't immediately use them.

Our Solution: Yield Tokenization

Bonded Finance splits deposits into two tokens:

• PT (Principal Tokens) – redeemable at maturity

• YT (Yield Tokens) – representing future rewards, tradable immediately

This lets users:

• Sell YT to unlock liquidity now

• Buy YT at a discount to earn yield later

We’ve already demonstrated this model by tokenizing VESU - the yield from Vesu’s DeFi Spring market, turning otherwise locked yield into a liquid, composable asset(ONLY IN OUR CONTRACT)

Architecture & Technical Stack

During the hackathon, our main focus was the design of smart contracts and protocol architecture, the most complex layer.

Instead of a basic liquidity pool, we implemented an order book-based system to match sellers and buyers of yield directly.
Going forward, our plan is to transition toward liquidity pools for greater efficiency and better UX.

Stack highlights:

• VESU: Tokenized DeFi Spring yield from Vesu Market

• EndurFi: Tokenizing STRK staking yield

• Pragma: Price feed oracle for accurate market pricing

• APIBARA: Used as an indexer to track deposits, mints, and trades on Starknet

Why Starknet?

Starknet gives us the scalability, affordability, and composability needed to build a truly seamless and modular yield market — with fast transactions, secure contracts, and low gas fees.

Progress So Far

We’ve built a fully functional MVP where:

• Users can create a YT order + someone car BUY this order position

• Trade yield immediately in a simple UI

Our MVP supports real use cases including tokenized DeFi Spring via VESU.

₿onded Finance & ₿itcoin

With Starknet’s growing support for Bitcoin scaling, Bonded Finance is positioned to unlock a powerful new opportunity:

Tokenizing and trading BTC yield, making it liquid, composable, and productive.

Today, most BTC is idle. Tomorrow, with Bonded:

• Bitcoin yield becomes tokenized

• BTC becomes instantly liquid and yield-bearing

• A true BTC fixed income market becomes possible

We're building the foundation for DeFi-native Bitcoin bonds.

What’s Next

Expand Yield Tokenization

We aim to tokenize every major yield source on Starknet, including:

• Forge Yield

• Paradex

• Ekubo

• Extended

• Vesu

• Opus

• Endur.fi

This will allow users to unlock liquidity from any yield stream on Starknet.

Transition to Liquidity Pools

We’ll move from our current order book system to a liquidity pool model to:

• Improve capital efficiency

• Reduce slippage

• Offer a smoother UX for both buyers and sellers

STRK Staking & Beyond

Deepen our integration with EndurFi to tokenize STRK staking rewards, making STRK yield composable and liquid.

Points & Incentives System

We're designing a points system to reward early users and liquidity providers across all Bonded markets.
This includes:

• Tracking YT buying/selling activity

• Reward multipliers based on time or volume

• Integrating with existing protocol point systems (e.g. Vesu, Paradex, Ekubo, AVNU, ETC) for shared incentive alignment

Bonded will not only unlock yield, it will boost rewards across the Starknet ecosystem.

Vision

Bonded Finance is building the missing bridge between future value and present utility.
From DeFi Spring to Bitcoin, and from VESU to STRK — every yield becomes liquid, tradable, and programmable.

We're not just unlocking yield.
We're building a bond market for the future of DeFi.
