Introduction
The launch of new blockchain networks often coincides with the establishment of two key DeFi protocols: Automated Market Maker (AMM)-based decentralized exchanges (DEXs) and lending platforms. These protocols attract liquidity, fostering early capital accumulation and economic infrastructure development. While DEXs efficiently handle trades through bonding curves, lending protocols face risks like oracle attacks due to their complex components.
Timeswap, a Polygon-based protocol, reimagines lending by utilizing bonding curves to eliminate liquidations and oracle dependencies.
Protocol Overview
Key Details
- Launch Date: March 22, 2022 (Mainnet)
- Funding: Seed round backed by Multicoin Capital, Mechanism Capital, and Defiance Capital (October 2021)
- Team: Filipino-led, with founders experienced in fintech, supply chain, and blockchain investments (including a Polygon angel investor).
How Timeswap Works
Timeswap automates lending via the XYZ=k bonding curve, where:
- X: Principal tokens (e.g., DAI)
- Y: Interest per second (e.g., 0.0000475 DAI for 15% APR)
- Z: Collateral tokens (e.g., ETH)
- k: Constant (similar to Uniswap’s XY=k).
Example: DAI-ETH Pool Setup
- Principal (X): 10,000 DAI
- Interest (Y): 15% APR → 0.0000475 DAI/sec
- Collateral (Z): 4.175 ETH (167% collateralization at $4,000/ETH)
- Curve: XYZ = 1.98 = k
Participant Roles
1. Lenders (Loan Providers)
Receive four token types:
- BPT: Bond Principal Tokens (share of principal pool)
- BIT: Bond Interest Tokens (share of interest pool)
- IPT/IIT: Insurance tokens for principal/interest coverage.
2. Borrowers
- Deposit collateral (e.g., ETH) to mint Collateral Debt Tokens (CDT) (ERC-721).
- Repay by deadline to unlock collateral; else, lenders claim it.
3. Liquidity Providers (LPs)
- Earn fees from spreads between lenders/borrowers.
- Receive LP tokens representing pool shares.
Mechanics in Action
Lender Scenario
Deposit: 1,000 DAI at 10% APR for 30 days.
- Receives: 1,000 BPT + 8.19 BIT + 0.37 IPT + 0.0077 IIT.
- Insurance: Covers defaults via collateral redistribution.
Borrower Scenario
- Loan: 1,000 DAI at 10% APR requires 0.4829 ETH (190% collateralization).
Advantages & Challenges
Pros
- No Oracle Risk: Immune to price manipulation attacks.
- Permissionless: Supports long-tail assets without restrictions.
Cons
- Volatility Exposure: Lenders may incur losses if collateral value plunges at maturity.
- Fixed-Term: Lacks flexibility compared to perpetual loans.
FAQs
1. How does Timeswap differ from Aave?
Timeswap uses bonding curves instead of oracles, avoiding liquidations but requiring fixed-term commitments.
2. Can lenders lose funds?
Yes, if collateral value drops significantly by maturity, lenders receive undervalued assets.
3. Is Timeswap live?
Yes, with periodic test markets on Polygon (e.g., USDC lending/MATIC borrowing).
