- Hardware wallet — long-term holdings and high-value signing
- DEX aggregator — best net execution across pools and chains
- DeFi protocols (lending, LP, staking) — the yield layer, one risk profile each
- Portfolio tracker (Zerion or DeBank) — read-only aggregate view including deposits
- Approval manager — periodic allowance review and revocation

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.
- →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.
- →DeFi
DeFi is financial infrastructure built as open smart contracts — lending, trading, staking and derivatives that anyone can use or compose.
- →Smart Contract
A smart contract is code deployed to a blockchain that executes deterministically when called, holding balances and enforcing rules without an operator.
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.
- →DEX Trading Workflow
Execute an on-chain swap deliberately: research, liquidity check, route comparison, sized order, then position monitoring.
- →Compare DEX Prices And Routes
Find the genuinely best execution for a swap by comparing net output after slippage, fees and gas across venues and chains.

Related prompts
Reusable prompts for this job.
- →DeFi Protocol Research Prompt
Decomposes a protocol's yield source, contract risk, oracle dependency and exit path into a written risk verdict.
- →Yield Comparison Prompt
Compares yield opportunities on a risk-adjusted basis instead of ranking them by advertised APY.
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.
- →Track Stablecoins
Monitoring stablecoin balances by chain and version surfaced $12k stranded in a bridged token with almost no exit liquidity.
- →Discover DeFi Opportunities
Ranking yields by real fee-based return instead of advertised APY moved capital from a 31% headline position to an 8.4% sustainable one.
- →Compare DEX Prices
Comparing net output instead of headline quotes recovered around 1.9% on a $180k swap by splitting it across two routes.
Comparisons & alternatives
Pick between the options.
- →CEX vs DEX
Centralised exchanges optimise for liquidity, fiat access and convenience; DEXs optimise for custody, permissionless listing and on-chain transparency.
- →MetaMask vs OKX Web3 Wallet
MetaMask is the EVM default with the widest DApp support; OKX Web3 Wallet bundles multi-chain coverage, a DEX aggregator and exchange integration in one app.
- →Phantom vs OKX Web3 Wallet
Phantom is a Solana-first wallet with best-in-class UX on that ecosystem; OKX Web3 Wallet is a generalist multi-chain wallet for users spread across networks.
- →DeFi vs Traditional Finance
DeFi offers open access, composability and transparent rules; traditional finance offers legal recourse, insurance and stability.
