DeFi
DeFi is financial infrastructure built as open smart contracts — lending, trading, staking and derivatives that anyone can use or compose.
/ quick answer
DeFi replaces intermediaries with contracts and collateral. Yields come from real activity (trading fees, borrowing demand, staking rewards) or from token emissions, which are temporary. Risk is layered: contract risk, oracle risk, liquidity risk, governance risk and your own key management. Composability makes both returns and failures spread across protocols.

What is an example of DeFi?
Supplying a stablecoin to a lending market, receiving a receipt token, then using it as collateral elsewhere — two protocols, two independent risks.

Related concepts
The vocabulary this page depends on.
- →Web3 Wallet
A Web3 wallet stores your keys and signs transactions, letting you hold assets and connect to on-chain applications without an intermediary.
- →Private Key
A private key is the secret number that authorises transactions from an address; the public address is derived from it, never the reverse.
- →DEX
A DEX is an exchange implemented as smart contracts, where trades settle on-chain from your own wallet instead of an internal exchange ledger.
- →Bridge
A bridge moves value between blockchains by locking or burning on one side and issuing a representation on the other.
Related workflows
Turn this into a repeatable process.
- →DeFi Yield Research Workflow
Evaluate a yield opportunity by decomposing where the return comes from and what has to break for it to disappear.
- →Stablecoin Web3 Workflow
Move stablecoins into self-custody and use them across Web3 applications without losing track of chain, version or exposure.
- →AI Crypto Research Workflow
A repeatable research loop: turn a question into market data, on-chain evidence and a written risk view before any position is considered.
- →Automated Crypto Alerts
Define the conditions that would change a decision, monitor them automatically, and receive one clean notification instead of watching charts.
Related tool stacks
The tools that run it in production.
- →DeFi Execution Stack
Web3 wallet, DEX aggregator, DeFi protocols and a portfolio tracker — the toolset for actually deploying capital on-chain.
Related prompts
Reusable prompts for this job.
- →Crypto Risk Analysis Prompt
Runs a pre-mortem on a position or protocol: enumerates failure modes, likelihood, impact and observable early warnings.
- →Recurring Crypto Workflow Prompt
Specifies a safe recurring on-chain automation with spend caps, idempotency, failure handling and a kill switch.
- →Crypto Market Analysis Prompt
Produces a structured market brief: regime, liquidity conditions, sector rotation, catalysts and what would change the view.
- →DeFi Protocol Research Prompt
Decomposes a protocol's yield source, contract risk, oracle dependency and exit path into a written risk verdict.
Related use cases
How people apply it, and what came out.
- →Use DeFi With A Web3 Wallet
A first-time DeFi user moved from an exchange to self-custody with a test-transfer routine and a 2% allocation cap, avoiding two protocol failures.
- →Finance Team Automates 14 Supplier Portals with Browser Agents

Comparisons & alternatives
Pick between the options.
- →DeFi vs Traditional Finance
DeFi offers open access, composability and transparent rules; traditional finance offers legal recourse, insurance and stability.
- →Web2 Apps vs Web3 Apps
Web2 apps authenticate with accounts and store state on private servers; Web3 apps authenticate with a wallet signature and keep state on a public chain.
- →Custodial vs Self-Custody
Custody choice is a swap between counterparty risk you cannot control and operational risk you can.
- →Stablecoins vs Bank Transfers
Stablecoin transfers settle in minutes on public rails; bank transfers settle slower but come with reversibility and regulated protection.
