DeFi Fundamentals
Stablecoins
What they are: Cryptocurrencies designed to maintain a stable value relative to an external reference, typically the US dollar. While most crypto prices fluctuate dramatically, stablecoins aim to stay at $1.
How DOLA works: DOLA is a debt-backed stablecoin—it's created when users borrow against crypto collateral on FiRM. Each DOLA in circulation is backed by more than $1 worth of collateral held in the protocol, plus additional safety buffers.
Why it matters: Stablecoins let you hold dollar-denominated value on-chain, earn yield without price exposure, and move value across blockchains without using traditional banking.
Key difference: Unlike algorithmic stablecoins, DOLA is over-collateralized with crypto assets and uses market-driven mechanisms to maintain its peg.
Collateral
What it is: Assets you deposit to secure a loan. Think of it like putting down a security deposit when renting an apartment—if you don't fulfill your obligations, the landlord keeps the deposit.
In DeFi lending: You deposit crypto (like ETH or wstETH) into a protocol, which locks it up while you borrow a different asset (like DOLA). If the value of your collateral drops too much relative to your loan, the protocol can sell your collateral to repay the debt.
Common collateral types on FiRM:
WETH - Wrapped Ethereum
wstETH - Wrapped staked ETH (Lido)
CVX - Convex governance token
INV - Inverse Finance governance token
sUSDe - Ethena's yield bearing USDe stablecoin
DOLA-wstUSR LP - A liquidity pool token composed of DOLA and wrapped-staked-USR from Resolv Labs
Important: Different collateral types have different risk profiles and borrowing capacities. Always understand the specific risks of the collateral you're using.
Collateral Factor
What it is: The maximum percentage of your collateral's value that you can borrow, expressed as a percentage or ratio.
Example:
You deposit $10,000 worth of ETH
ETH has an 82% collateral factor on FiRM
You can borrow up to $8,200 DOLA
Your loan-to-value (LTV) ratio is 82%
Why it's not 100%: The buffer protects the protocol from rapid price drops. If ETH crashes 10%, your $10,000 collateral becomes $9,000, but you still owe $8,200—the protocol still has cushion before bad debt occurs.
Real-world analogy: Like how banks only lend 80% of a home's value for a mortgage, DeFi protocols only allow borrowing a portion of collateral value to maintain safety margins.
65%
$6,500 per $10,000
Conservative
75%
$7,500 per $10,000
Moderate
82%
$8,200 per $10,000
Aggressive
85%+
$8,500+ per $10,000
High Risk
Best Practice: Even if your market allows 82% collateral factor, consider borrowing only 70-75% to protect against volatility and liquidation risk.
Liquidation
What it is: The forced sale of your collateral to repay your loan when the collateral's value falls too low relative to your debt.
When it happens: Each market has a liquidation threshold slightly above the collateral factor. If your collateral value drops and your LTV ratio crosses this threshold, liquidators can repay your debt and claim your collateral plus a bonus.
Example liquidation scenario:
You deposit $10,000 ETH, borrow $8,000 DOLA (80% LTV)
ETH price drops 15%, your collateral now worth $8,500
Your LTV is now 94% ($8,000 / $8,500)
This exceeds the liquidation threshold
Liquidators repay your $8,000 debt
They receive $8,400 worth of your ETH (liquidation penalty)
You lose your collateral but debt is cleared
How to avoid liquidation:
Maintain conservative LTV ratios (stay well below maximum)
Monitor your positions regularly
Set price alerts for your collateral
Keep extra collateral ready to add if needed
Repay debt or add collateral before liquidation threshold
Critical: Liquidation is permanent and happens automatically. You cannot stop it once triggered. Always maintain a safety buffer and monitor positions during volatile markets.
Yield & APY
Yield: Returns earned on deposited or staked crypto, similar to interest on a savings account but typically much higher.
APY (Annual Percentage Yield): The annualized rate of return including compound interest. If you earn 10% APY and reinvest earnings, you'll have 110% of your starting amount after one year.
APR (Annual Percentage Rate): The simple annualized rate without compounding. A 10% APR means you earn 10% over one year if you don't reinvest.
Why APY > APR: APY accounts for earning returns on your returns (compounding). The more frequently rewards compound, the bigger the difference between APR and APY.
Example:
10% APR with no compounding = 10% total return
10% APR compounded daily = ~10.52% APY
10% APR compounded per block = ~10.54% APY
Where yield comes from in Inverse Finance:
sDOLA: DBR revenue from FiRM borrowers
sINV: DBR revenue + anti-dilution INV rewards
jrDOLA: DBR insurance premium + sDOLA base yield
INV staking: Anti-dilution rewards + DBR streaming
Remember: Past yields don't predict future performance. APY fluctuates based on protocol revenue, participation, and market conditions.
Gas Fees
What they are: Transaction fees paid to blockchain validators to process your transactions. On Ethereum, gas fees are paid in ETH.
Why they exist: Validators (computers running the network) need compensation for processing transactions and securing the blockchain. More complex transactions require more computational work and therefore cost more gas.
Gas fee factors:
Network congestion: Higher demand = higher fees
Transaction complexity: Simple transfers cheaper than complex smart contract interactions
Transaction speed: Pay more to prioritize your transaction
How to reduce gas costs:
Transact during low-traffic periods (weekends, late nights UTC)
Batch operations when possible
Use gas price trackers to time transactions
Consider L2 chains where DOLA is available (Optimism, Base, Arbitrum)
Gas Tip: You always need some ETH in your wallet to pay gas fees, even when depositing or withdrawing. Keep at least $50-100 worth of ETH available for transaction costs.
Wallets
What they are: Applications that store your private keys and let you interact with DeFi protocols. Your wallet is your identity in DeFi—whoever controls the private keys controls the assets.
Types of wallets:
Hot Wallets (Software): MetaMask, Coinbase Wallet, Rainbow, Frame
Convenient for frequent transactions
Higher risk if your computer is compromised
Good for: Active DeFi use, moderate amounts
Cold Wallets (Hardware): Ledger, Trezor, GridPlus Lattice
Maximum security, offline storage
Less convenient, requires physical device
Good for: Large amounts, long-term holdings
Smart Contract Wallets: Safe (formerly Gnosis Safe), Argent
Programmable wallets with advanced features
Can require multiple signatures (multisig)
Good for: DAOs, shared accounts, advanced users
CRITICAL SECURITY RULES:
Never share your seed phrase or private keys with anyone
Inverse Finance team will never DM you first
Always verify you're on official sites (check URL carefully)
Bookmark official sites and use bookmarks, not search engines
Be extremely skeptical of "support" offering to help via DM
If something seems too good to be true, it is
Inverse Finance-Specific Concepts
Governance & DAOs
DAO (Decentralized Autonomous Organization): An organization controlled by token holders through on-chain voting rather than traditional corporate management.
How Inverse Finance governance works:
Someone creates a proposal (on forum or directly on-chain)
Proposal goes through discussion and refinement (temperature check)
Formal on-chain vote with INV tokens
If passed, proposal executes automatically via smart contracts
What governance controls:
Parameter setting for FiRM markets
Budget approvals for DAO working groups (treasury, risk, product, growth)
Protocol upgrades and new features
INV tokenomics
Emergency actions
Voting power: 1 INV = 1 vote. The more INV you hold (or have delegated to you), the more influence you have over protocol decisions.
Why it matters: Unlike centralized companies, INV holders collectively own and control Inverse Finance. There's no CEO who can make unilateral decisions.
Get involved: Even if you don't have large INV holdings, participating in forum discussions and voting helps shape the protocol's future. Active governance is what makes DeFi truly decentralized.
FiRM
What it is: Inverse Finance's lending protocol that enables fixed-rate borrowing for any duration.
How it differs from other lending protocols:
Traditional DeFi Lending (Aave, Compound):
Variable interest rates that change constantly
Rates spike during high demand
Unpredictable borrowing costs
Can't plan long-term
FiRM:
Fixed costs for any duration
Buy DBR upfront, know exact borrowing cost
Extend loans indefinitely
Full predictability
Key features:
Personal Collateral Escrows (isolated positions)
Pessimistic Price Oracles (conservative pricing)
Governance tokens keep voting rights when used as collateral
No duration limits on loans
When to use FiRM: Any time you need predictable borrowing costs, want to maintain governance rights while borrowing, or plan to hold a loan for extended periods.
DBR (DOLA Borrowing Rights)
What it is: An ERC-20 token that represents your right to borrow DOLA on FiRM. One DBR lets you borrow one DOLA for one year at zero interest.
How it works:
You buy DBR tokens (on DEXs or through auctions)
Each DBR represents 1 DOLA borrowed for 1 year
DBR balance decreases as time passes while you have a loan
When DBR hits zero, forced replenishment occurs (expensive)
Examples:
One-year loan:
Borrow 1,000 DOLA for 1 year
Need 1,000 DBR
DBR costs $0.02 each = $20 total borrowing cost
Effective APR: 2%
Six-month loan:
Borrow 1,000 DOLA for 6 months
Need 500 DBR (borrow half the time)
DBR costs $0.02 each = $10 total borrowing cost
Effective APR: 2% (annualized)
Three-year loan:
Borrow 1,000 DOLA for 3 years
Need 3,000 DBR
DBR costs $0.02 each = $60 total borrowing cost
Effective APR: 2%
Why DBR is powerful:
Rate locking: Buy DBR when cheap, use later when rates are higher
Predictability: Know exact costs upfront
Flexibility: Borrow for any duration, extend anytime
Tradeable: DBR can be bought, sold, or transferred
Speculation: DBR price fluctuates based on demand for DOLA loans
DBR Strategy: Always buy more DBR than you minimally need. If your DBR hits zero, forced replenishment costs can be 5-10x normal DBR prices. Maintain at least a 30-day buffer.
Personal Collateral Escrow (PCE)
What it is: Your own isolated smart contract that holds your collateral on FiRM. Each user gets their own PCE for each collateral type they use.
Why it matters: Problems in one market can't affect your positions in other markets. This is a major safety improvement over pooled collateral systems.
Example of protection:
You have two positions: one with WETH, one with CVX
CVX market experiences issues (oracle failure, governance attack, etc.)
Your CVX position might be at risk
Your WETH position is completely unaffected
Problems are contained to individual markets
Compare to traditional lending:
Aave/Compound: All your collateral in one pool, cross-collateralization
FiRM: Each position isolated, no cross-contamination
Benefit: PCE gives you peace of mind that experimental or risky collateral types won't endanger your safer positions.
Pessimistic Price Oracle (PPO)
What it is: A conservative price feed system that uses the lower of two oracle prices to value your collateral.
How it works:
FiRM queries two different price oracles
Takes the pessimistic (lower) price for collateral valuation
Uses optimistic (higher) price for debt valuation
Creates a safety buffer against oracle manipulation
Example:
Chainlink oracle says ETH = $3,000
Fallback oracle says ETH = $2,950
FiRM values your ETH collateral at $2,950 (lower)
If you're repaying debt, uses $3,000 (higher)
Why it's important:
Protects against oracle failures or manipulation
Reduces bad debt risk
Gives users confidence in system stability
Creates implicit safety margin
Trade-off: You get slightly lower borrowing capacity than if using a single oracle, but the safety benefit outweighs this minor inconvenience.
What this means for you: Your actual borrowing capacity might be 1-2% lower than theoretical maximum, but you're protected from oracle exploits that have devastated other protocols.
ERC-4626 Vaults
What they are: A standardized way to create yield-bearing tokens that wrap underlying assets. Think of them as "receipt tokens" that represent your share of a growing pool.
How they work:
You deposit DOLA into an ERC-4626 vault
Receive sDOLA tokens representing your share
The vault earns yield (DBR rewards)
Yield auto-compounds into the vault
Each sDOLA becomes worth more DOLA over time
Redeem sDOLA anytime for underlying DOLA + accrued yield
Inverse Finance ERC-4626 vaults:
sDOLA: Wraps DOLA, earns DBR yield
sINV: Wraps staked INV, earns anti-dilution + DBR rewards
jrDOLA: Wraps DOLA with first-loss risk, earns enhanced yield
Benefits of the standard:
Composability: Works with other DeFi protocols expecting ERC-4626
Predictability: Standard interface everyone understands
Safety: Well-audited, battle-tested standard
Think of it like: A money market fund. You deposit dollars, get shares, the fund invests and earns returns, your shares become worth more dollars over time, redeem anytime.
Tranches (Senior vs Junior)
What they are: Different layers of capital with different risk/reward profiles, like different floors in a building that flood from bottom up.
Senior Tranche (sDOLA):
Lower risk, lower yield
Gets paid first
Protected by junior tranche buffer
Can withdraw anytime
Capital is safe unless junior tranche is completely wiped out
Junior Tranche (jrDOLA):
Higher risk, higher yield
Accepts first losses
Gets paid after senior tranche
Withdrawal delays to prevent bank runs
Capital can be partially or fully lost during bad debt events
Example scenario:
Total deposits: $10M ($8M senior sDOLA, $2M junior jrDOLA)
Bad debt event: $1M shortfall
Junior tranche absorbs the loss (now worth $1M)
Senior tranche unaffected (still worth $8M)
Junior holders lost 50%, senior holders lost 0%
Why tranches exist:
Let users choose their risk tolerance
Enable protocol scaling with less systemic risk
Create market-driven insurance mechanisms
Attract different types of capital
Choose based on your risk tolerance: If you can't afford to lose principal, use sDOLA. If you want higher yields and can accept capital loss risk, consider jrDOLA.
Slashing
What it is: The permanent reduction of your deposited capital to cover protocol losses. Only applies to jrDOLA (junior tranche).
When it happens:
A borrower's collateral value drops below their debt
Liquidation occurs but proceeds are insufficient
Bad debt remains after liquidation
jrDOLA vault assets are used to repay the shortfall
All jrDOLA holders share the loss proportionally
Example:
You deposit 10,000 DOLA to jrDOLA
Protocol experiences $500K bad debt
Total jrDOLA vault has $5M
Slashing event: 10% loss ($500K / $5M)
Your 10,000 DOLA is now worth 9,000 DOLA
Loss is permanent
How to think about it:
jrDOLA is insurance you're selling to the protocol
You earn premiums (enhanced yield)
Sometimes you have to pay claims (slashing)
If claims exceed premiums, you lose money
If premiums exceed claims, you profit
Not for everyone: Only deposit to jrDOLA if you fully understand and accept the possibility of permanent capital loss up to 100%.
Risk Concepts
Smart Contract Risk
What it is: The risk that bugs or vulnerabilities in smart contract code could be exploited, resulting in loss of funds.
Why it exists:
Smart contracts are immutable (can't be easily changed after deployment)
Complex code can have unexpected edge cases
Even audited code can have undiscovered vulnerabilities
Composability means risks compound across protocols
How Inverse Finance mitigates this:
Multiple audits from reputable firms (Sherlock, ChainSecurity, yAudit, Nomoi)
Public audit contests with competitive bug bounty
Gradual rollouts of new features
Time-locks on upgrades
Bug bounty program for responsible disclosure
What you can do:
Only deposit amounts you can afford to lose
Check that protocols are audited before using
Consider purchasing cover (insurance) from Nexus Mutual
Diversify across multiple protocols
Avoid new, unaudited protocols
Reality check: All DeFi carries smart contract risk. No amount of auditing can guarantee 100% safety. Even the most reputable protocols have been exploited. Never invest more than you can afford to lose entirely.
Oracle Risk
What it is: The risk that price feeds used by the protocol are manipulated, fail, or provide inaccurate data, leading to incorrect liquidations or bad debt.
Why oracles matter:
Protocols need external price data to value collateral
If oracle says your ETH is worth $1,000 when it's actually $3,000, you might get wrongly liquidated
If oracle says it's worth $5,000 when it's actually $3,000, the protocol takes on bad debt
Types of oracle attacks:
Flash loan manipulation of spot prices
Exchange exploits or failures affecting price feeds
Oracle provider going offline
Malicious oracle operators
How FiRM protects against oracle risk:
Pessimistic Price Oracle (uses lower of two prices)
Multiple oracle providers (Chainlink + fallback)
Time-weighted averages prevent flash loan attacks
Governance can update oracles if problems detected
Liquidation Cascade Risk
What it is: When falling collateral prices trigger liquidations, which creates selling pressure, which lowers prices further, which triggers more liquidations—a death spiral.
How it happens:
Market downturn begins, collateral prices drop
Some positions hit liquidation threshold
Liquidators sell collateral to repay debt
Increased selling pressure lowers prices further
More positions become liquidatable
Cycle repeats, accelerating downward
Historical examples:
Black Thursday 2020 (MakerDAO)
Terra/Luna collapse 2022
FTX contagion 2022
How to avoid being caught in cascades:
Maintain very conservative collateral ratios
Monitor positions during volatile markets
Set price alerts well above liquidation threshold
Have capital ready to add collateral quickly
Consider deleveraging during uncertainty
Cascade Warning: The most dangerous liquidations happen during cascades because gas fees spike (making it expensive to save your position) and DEX liquidity dries up (making it hard to buy more collateral or repay debt quickly).
