Lexicon

DeFi, in plain English.

Every term you'll meet in Mo'Stash, explained without the jargon.

1inch

A DEX aggregator that finds the best swap route across many exchanges. Mo'Stash routes EVM swaps through 1inch.

Aave

A leading lending protocol where you deposit assets to earn interest or borrow against collateral. Mo'Stash reads your Aave position and health factor.

Airdrop

Free tokens distributed to users, often to reward early activity or to decentralize ownership of a protocol.

Allowance

The amount of a token you've authorized a smart contract to spend on your behalf. See Approval.

AMM

Automated Market Maker — instead of an order book, swaps draw from a pool of two tokens and the price is set by their ratio (x × y = k). The engine behind DEXs like Uniswap and Curve.

Approval

Before a protocol can move your tokens, you sign a one-time approval. Beware unlimited approvals to unknown contracts — they can drain your wallet. They can be revoked.

APR

Annual Percentage Rate — the yearly interest rate of a position, not accounting for compounding. Most lending protocols quote APR.

APY

Annual Percentage Yield — the yearly return including the effect of compounding. Auto-compounding vaults like Beefy quote APY.

Auto-compounding

Automatically reinvesting your rewards so your interest earns interest. Vaults like Beefy do this for you.

Beefy

A yield optimizer that auto-compounds your farming rewards across many chains and pools.

Borrowing

Taking a loan against collateral you deposit. You keep your asset (e.g. ETH) while accessing liquidity (e.g. USDC) — but watch your health factor.

Bridge

A protocol that moves tokens from one blockchain to another. Mo'Stash compares routes to find the cheapest. Bridges are a frequent hack target — use trusted ones.

CEX

Centralized Exchange (e.g. Binance, Coinbase) — a company that holds your funds. The opposite of a DEX, where you keep custody.

Collateral

Assets you deposit to back a loan. If their value drops too far relative to your debt, your position can be liquidated.

Composability

DeFi's 'money legos': protocols stack on each other. Deposit on Aave and you receive an aToken you can reuse elsewhere — everything connects.

Curve

A DEX optimized for swapping similar assets (like stablecoins) with very low slippage and minimal impermanent loss.

Custodial

When a third party holds your private keys (and therefore your funds). Mo'Stash is the opposite: non-custodial.

DAO

Decentralized Autonomous Organization — a protocol governed by its token holders, who vote on changes.

DeFi

Decentralized Finance — financial services (lending, trading, staking) running on public blockchains without banks or intermediaries.

Depeg

When a stablecoin loses its peg and drifts from its target value (e.g. below $1). Algorithmic stablecoins are most at risk — UST collapsed this way.

DEX

Decentralized Exchange — trade directly from your wallet via smart contracts, keeping custody of your funds. Uniswap and Curve are DEXs.

EigenLayer

A restaking protocol: you deposit liquid-staking tokens like stETH to earn additional rewards by securing other networks.

ERC-20

The token standard most assets on Ethereum follow, making them interoperable across wallets and protocols.

Flash loan

Borrowing a large amount with no collateral, as long as it's repaid within the same transaction. Used for arbitrage — and sometimes for attacks.

Gas

The fee paid to a blockchain to process a transaction. On Ethereum it is paid in ETH and varies with network demand. A failed transaction still costs gas.

Governance token

A token that grants voting power over a protocol's decisions — fees, upgrades, treasury.

Health factor

A number representing how safe a lending position is. Below 1.0 the position is liquidated. Mo'Stash alerts you before you get close.

Impermanent loss

The temporary loss a liquidity provider can face when the prices of pooled assets diverge. The pool sells the rising asset, so you end up with less than if you'd just held. Near-zero on stablecoin pairs.

KYC

Know Your Customer — identity verification required by centralized services. Mo'Stash is no-KYC; any fiat on-ramp KYC is handled by third parties.

Layer 2

A network built on top of a Layer 1 (like Ethereum) to make transactions faster and cheaper. Arbitrum is an L2 — which is partly why bridges exist.

Lending

Supplying your tokens to a pool (like Aave) that others borrow from, earning interest in return. Usually withdrawable any time.

Lido

The largest liquid-staking protocol: stake ETH and receive stETH, which keeps earning and stays usable across DeFi.

Liquid staking

Staking your assets while receiving a tradable token in return (e.g. ETH → stETH), so your capital stays usable.

Liquidation

The forced sale of your collateral when your health factor falls below the safe threshold, used to repay your debt — usually with a penalty.

Liquidity pool

A reserve of two tokens that powers an AMM. Traders swap against it; liquidity providers supply it and earn a share of the fees.

LP

Liquidity Provider — someone who deposits two tokens into a pool to earn a share of swap fees, while accepting impermanent-loss risk.

LTV

Loan-To-Value — the ratio of your borrowed amount to your collateral value. As your collateral's price falls, LTV rises toward the liquidation threshold.

MEV

Maximal Extractable Value — bots reorder or 'sandwich' your transaction to profit from it. A reason to set sensible slippage.

Mnemonic

A 12 or 24-word seed phrase that backs up your wallet. Whoever holds it controls the funds — never share it.

Morpho

A lending protocol with configurable, market-based lending. Mo'Stash uses Morpho Blue for peer-to-peer lending.

Native token

The base coin of a chain, used to pay gas — ETH on Ethereum and Arbitrum, BNB on BNB Chain.

Non-custodial

A wallet or app where you alone hold the private keys. Mo'Stash never has server-side access to your funds.

Oracle

A service that feeds real-world prices into smart contracts (e.g. Chainlink). Critical for accurate liquidations; manipulated oracles cause exploits.

P2P lending

Lending directly to another user on terms you set, rather than to a shared pool. Higher yield, higher risk. Mo'Stash uses Morpho Blue.

Perpetuals

Perpetual futures ('perps') — leveraged bets on a token's price with no expiry date. Advanced and high-risk.

Private key

The secret that controls a wallet and signs transactions. Derived from your seed phrase and, in Mo'Stash, it never leaves your device.

Restaking

Re-using already-staked assets (like stETH) to secure additional protocols and earn extra yield, e.g. via EigenLayer — with cumulative risk.

Rug pull

A scam where a project's creators drain its liquidity or abandon it, leaving holders with worthless tokens.

Seed phrase

Your 12–24 word wallet backup (also called a mnemonic). Anyone who has it controls your funds — store it offline and never share it.

Slippage

The difference between the expected price of a swap and the executed price. Mo'Stash lets you cap it (typically 0.3–0.5%).

Smart contract

Self-executing code on a blockchain. Protocols like Aave and 1inch are smart contracts — powerful, but bugs can be exploited.

Stablecoin

A token pegged to a stable asset, usually the US dollar — e.g. USDC, USDT. Common for lending and yield. Three types: fiat-backed (safest), crypto-backed, and algorithmic (riskiest).

Staking

Locking tokens to help secure a proof-of-stake network in exchange for rewards.

stETH

Lido's liquid-staking token representing staked ETH. It accrues staking rewards and stays tradable and usable in DeFi.

Swap

Exchanging one token for another. Mo'Stash routes EVM swaps through 1inch and Solana swaps through Jupiter.

Token

A digital asset issued on a blockchain — it can represent money (USDC), a stake (stETH), governance rights, and more.

TVL

Total Value Locked — the amount of assets deposited in a protocol, a common gauge of its size and traction.

Vault

A smart contract that automates a strategy for you — for example depositing and auto-compounding rewards (Beefy).

Wallet

Software that stores your keys and lets you sign transactions. A non-custodial wallet keeps those keys on your device.

Yield

The return earned on deposited assets, from lending interest, liquidity fees or staking rewards. Beware unusually high yields driven by temporary token emissions.

Yield optimizer

A tool that scans protocols for the best available return and helps you move funds there. Mo'Stash automates this across chains.
