TradFi → DeFi
You already know the instrument. Start there. Every entry is a TradFi anchor and the DeFi primitives that rhyme with it.

A shared, tamper-evident ledger

What Is a Blockchain? ↗A database thousands of strangers maintain together, where no one can quietly edit the past — the substrate all of DeFi runs on.

Actively-managed fund / robo-advisor

Yield Vaults & Aggregators ↗Deposit once, let a strategy harvest and compound for you. The 'set and forget' layer — and a stack of inherited risk.

Bank confidentiality with Bank Secrecy Act reporting

On-Chain Privacy: Pseudonymity, Mixers & Zero-Knowledge ↗A public ledger makes pseudonymous the opposite of private. Mixers, stealth addresses and zero-knowledge proofs claw some privacy back — and run straight into sanctions and money-transmission law.

Bond stripping (STRIPS) + rate swaps

Pendle ↗Yield tokenization: split yield-bearing assets into PT (principal) + YT (yield).

Casino chips (fungible) vs. trading cards (unique)

Tokens & Standards ↗ERC-20 made every token speak the same language — the standard that turned Ethereum into a financial Lego set.

Central bank OMO + prisoner's dilemma

OHM — OlympusDAO ↗OlympusDAO — protocol-owned liquidity via bonds, rebase staking, (3,3) game theory.

Clearing utility + asset managers

Morpho — Primitive + Curation ↗A minimal, immutable lending primitive plus a curation layer — the architecture that grew to ~$7B by separating the engine from the risk management.

Collateralized repo + currency board

MakerDAO ↗CDP-backed DAI stablecoin. On-chain repo desk with code-enforced margin calls.

Commercial bank → bank holding company

Aave: v3 to v4 Architecture ↗DeFi's largest lender, from its monolithic v3 pool (isolation, eMode, caps) to the modular hub-and-spoke v4 launched in 2026.

Continuous-quote market maker

Uniswap v2 ↗Constant-product AMM (x·y=k) — the passive market maker every DEX descends from.

Cross-border correspondent settlement

Cross-Chain Bridges ↗Moving value between chains that can't see each other — DeFi's most-exploited category by far.

Currency board / money-market fund share

Stablecoin Design ↗How a token holds a dollar: fiat-backed, crypto-backed, or algorithmic — and what each one risks.

Dual control / four-eyes principle

Key Management: Multisig, MPC & Hardware Wallets ↗Every crypto loss is a key problem: stolen, lost, or signed away. Hardware wallets, multisig, MPC and social recovery each relocate the single point of failure — none of them deletes it.

Enterprise risk register

The DeFi Risk Taxonomy ↗A capstone map of every way DeFi loses money — so you can name the risk before it names you.

Equities market ↔ crypto market

Crypto vs. Stocks ↗The honest comparison: where tokens rhyme with stocks, where the analogy quietly breaks, and what's genuinely new.

Front-running + payment for order flow

MEV — Maximal Extractable Value ↗Value extracted via transaction ordering — sandwiches, salmonella traps, builder auctions.

Fund-of-funds with auto-reinvestment

Pickle Finance ↗pJar yield optimizer — auto-harvesting strategy vaults with DILL ve-governance.

Futures on events, not prices — Iowa Electronic Markets, Intrade

Prediction Markets ↗Markets that price the probability of a future event directly — outcome shares, resolution, and the order types used to trade them.

Futures with no expiry, pegged by funding

Perpetual Futures ↗Leveraged exposure that never expires, tied to spot by a funding rate — the highest-volume product in crypto.

FX desk for pegged pairs

Curve & the StableSwap Invariant ↗An AMM tuned for assets that should trade 1:1 — flat curve near parity, deep stable liquidity, the engine of the Curve wars.

Hostile takeover via equity incentives

SushiSwap ↗Uniswap fork that executed the vampire attack — liquidity bought with SUSHI emissions.

Independent model validation (second-line review)

Smart Contract Security: Bugs, Audits & Bounties ↗Deployed contracts are public, usually immutable, and hold real money — so every bug is a bounty for whoever finds it first. Tests, audits, formal verification and bug bounties each cover a different slice.

Limit-order market making / short straddle

Uniswap v3 ↗Concentrated liquidity: LPs pick price ranges. Up to ~4000× capital efficiency, active risk.

Listed options & structured products desk

DeFi Options & Structured Vaults ↗On-chain calls and puts, and the vaults that auto-sell them for yield — convexity as a composable primitive.

Margin call + forced position close-out

Liquidations ↗The backstop that keeps lending pools solvent: when health factor drops below 1, keepers seize collateral at a discount.

Market impact & price discovery

How Liquidity Affects Pricing ↗Price isn't a number a protocol stores — it's an emergent result of where liquidity sits. Thin books move on a whisper; deep ones absorb a shout.

Market-data feed / reference rate

Oracles & Price Feeds ↗How off-chain prices get on chain — and why a bad feed is the root cause of most DeFi hacks.

Market-impact / bonding-curve model

AMM Pricing Math ↗The exact arithmetic behind a swap quote: how a constant-product curve turns reserves into a price and a trade into impact.

Money market fund, rate set by utilization

Compound ↗Algorithmic money market — interest rates set purely by pool utilization.

Money-market rate curve set by supply/demand

Interest Rate Models ↗How a pool prices money with no rate desk: utilization in, borrow APR out.

Notarized signature + tamper-evident seal

Encryption, Hashing & Signatures ↗A blockchain runs on hashes and signatures, not encryption — every transaction is public by design. Knowing which primitive does what is the difference between reading a security claim and being sold one.

Online-banking TLS session (the padlock)

Encryption, Hashing & Signatures ↗A blockchain runs on hashes and signatures, not encryption — every transaction is public by design. Knowing which primitive does what is the difference between reading a security claim and being sold one.

Order-book depth & market impact

Understanding Liquidity ↗Depth, slippage, and price impact — why a $1M trade in one pool is free and ruinous in another.

Penetration test + SOC 2 attestation

Smart Contract Security: Bugs, Audits & Bounties ↗Deployed contracts are public, usually immutable, and hold real money — so every bug is a bounty for whoever finds it first. Tests, audits, formal verification and bug bounties each cover a different slice.

Prime broker + intraday credit line

Aave v1 ↗Pooled lending + flash loans: uncollateralized atomic credit, repaid or reverted.

Prime brokerage cross-margining

Fluid ↗Unified liquidity layer — one pool of capital serving lending, vaults and DEX at once.

Programmable corporate account with spending rules

Account Abstraction ↗Make a wallet a smart contract: social recovery, spending limits, gas paid in any token, batched actions. Fixing crypto's worst UX.

Rehypothecated collateral securing multiple obligations

Restaking & EigenLayer ↗Reuse staked ETH to secure other protocols for extra yield — pooled security, stacked slashing risk.

Rehypothecation + cross-margining

Multi-Utilization Liquidity Layers ↗One collateral pool, many simultaneous jobs — rehypothecation with public books.

Risk-tiered prime brokerage

Euler ↗Permissionless lending with risk-tiered assets, reactive PID rates, soft liquidations.

Safe-deposit box + a signature

Wallets & Keys ↗A wallet doesn't hold coins — it holds the keys that prove they're yours. Lose the key, lose the funds. There is no reset.

Secured margin lending desk

Lending & Borrowing, End to End ↗The whole loop: supply collateral, borrow against it, stay above your health factor, or get liquidated.

Shareholder voting, automated and on-chain

DAO Governance ↗Who controls a protocol after launch? Token-holders, voting on-chain — with timelocks, delegation, and a long history of governance attacks.

Short-gamma inventory P&L

Impermanent Loss (Divergence Loss) ↗Divergence loss: why LPs underperform holding. IL = 2√P/(1+P) − 1.

Smart order router / best execution

DEX Aggregators & Intents ↗Liquidity is fragmented across hundreds of pools; aggregators and solvers find best execution and shield you from MEV.

Street-name ownership / DTC custody chain

Issuers, Custodians & the Claim Chain ↗Who actually holds the asset, and who owes you what. The issuer–custodian–broker chain behind tokenized equities, neobanks, and every 'backed' token.

Tokenized equities ↔ depositary receipt (ADR)

Issuers, Custodians & the Claim Chain ↗Who actually holds the asset, and who owes you what. The issuer–custodian–broker chain behind tokenized equities, neobanks, and every 'backed' token.

Tokenized money-market fund / private credit

Real-World Assets (RWA) ↗Putting off-chain assets — Treasuries, credit, gold — on chain as tokens. DeFi's bridge to trillions in traditional value.

Tradable receipt on a term deposit

Liquid Staking ↗Stake ETH to secure the chain, get a liquid receipt (stETH) that keeps earning while you use it everywhere else.

Unbacked currency peg defense (and its bank runs)

Algorithmic Stablecoins ↗Holding a peg with mechanism instead of collateral — elegant on paper, reflexive in a crisis. The UST/LUNA case study.

Universal bank vs. ring-fenced subsidiaries

Monolithic vs. Modular Lending ↗One shared pool or many isolated markets — the architecture choice that decides whether bad debt is contained or contagious.

Vault access with a quorum (HSM key ceremony)

Key Management: Multisig, MPC & Hardware Wallets ↗Every crypto loss is a key problem: stolen, lost, or signed away. Hardware wallets, multisig, MPC and social recovery each relocate the single point of failure — none of them deletes it.

ZCB + interest rate swap

Pendle PT Tokens as Zero-Coupon Bonds ↗Pendle PT as zero-coupon bond, YT as the floating leg of an interest rate swap.
