What are stablecoins?

Stablecoins are crypto tokens designed to maintain a 1:1 peg with a fiat currency, typically the US dollar. The largest are USDT (Tether), USDC (Circle), and DAI (MakerDAO). Stablecoins enable fast, global, low-cost dollar transfers using crypto rails.

Are stablecoins safe?

The largest fiat-backed stablecoins (USDC, USDT) hold reserves in cash and short-term US Treasuries and have published attestations. Risks: regulatory action (especially in the US), reserve mismanagement, and de-pegging during stress events (e.g. USDC briefly de-pegged in March 2023 during the SVB crisis).

How do I earn yield on stablecoins?

Major DeFi yield sources for stablecoins (5–9% APY in 2026): lending on Aave or Compound, providing liquidity in stablecoin pools (Curve), and on-chain treasury bills (sDAI, USDM). Avoid any platform offering 20%+ on stablecoins — that yield is unsustainable or hides significant risk.

Are stablecoins legal?

In most jurisdictions, yes. The EU's MiCA regulation came into effect for stablecoins in mid-2024 with strict reserve and disclosure rules. The US is finalising stablecoin legislation. Dubai (VARA), Singapore (MAS), and the UK (FCA) all permit licensed stablecoin issuers.

What is a DeFi aggregator?

A DeFi aggregator is a platform that routes your crypto swaps across hundreds of decentralised exchanges (DEXes) simultaneously to find the best rate and lowest slippage. Instead of trading on a single DEX like Uniswap, an aggregator like Steyble splits your trade across multiple pools and chains to maximise your output.

What is a crypto super app?

A crypto super app is a single non-custodial platform that combines every DeFi service — token swapping, staking, perpetuals trading, prediction markets, copy trading, cross-chain bridging, and crypto cards — in one interface. Steyble is a crypto super app, meaning you never need to switch between multiple DeFi applications.

Is Steyble self-custodial?

Yes. Steyble is entirely non-custodial and self-custodial. You hold your private keys at all times. Steyble provides the interface and smart contract routing, but never holds, controls, or has access to your assets. Every transaction requires your explicit wallet signature.

How do prediction markets work in crypto?

Crypto prediction markets let you buy or sell shares in the outcome of real-world events using on-chain smart contracts. If you buy a 'Yes' share at $0.35, you receive $1 if the event occurs (a $0.65 profit) or lose $0.35 if it does not. Markets cover crypto prices, elections, sports results, and macro events. Steyble's prediction markets are non-custodial — your funds remain in your wallet until settlement.

What are perpetual futures in crypto?

Perpetual futures (perps) are leveraged crypto trading contracts with no expiry date. Unlike traditional futures that expire monthly, perps let you hold long or short positions indefinitely. A periodic funding rate keeps the perp price aligned with spot. Steyble perpetuals run on decentralised smart contracts — you trade directly from your own wallet with full transparency into liquidation parameters.

How does copy trading work on Steyble?

Copy trading on Steyble automatically mirrors the on-chain trades of verified top-performing wallet strategies. You choose the wallets you want to copy, set your position sizing and risk limits, and Steyble replicates their trades in real time. Unlike centralised copy trading, Steyble is non-custodial — you never give up control of your funds.

What is the best way to earn passive income with crypto in 2026?

The best methods for passive crypto income in 2026 are: (1) liquid staking ETH or SOL at 3.5–8% APY, (2) lending stablecoins on lending protocols at 5–9% APY, (3) non-custodial copy trading to mirror proven wallet strategies, (4) providing liquidity to stablecoin pools at 3–6% APY, and (5) on-chain prediction markets for event-driven returns. Steyble provides access to all five methods in a single platform.

What is the best DEX aggregator in 2026?

The best DEX aggregators in 2026 route across 15+ blockchains and 100+ liquidity sources with MEV protection. Steyble's swap aggregator covers 250+ liquidity sources across Ethereum, Solana, Arbitrum, Base, and more — consistently delivering better rates than going directly to any single DEX. For large swaps, using an aggregator saves 0.5–2% per transaction.

The Stablecoin Trilemma: Decentralisation, Efficiency, Stability

Every stablecoin design picks two of three properties. Understanding the trilemma explains why USDC, DAI, and USDe are different products.

The stablecoin trilemma is the simple but rigorous framework that every stablecoin design must navigate: decentralisation, capital efficiency, and stability. You can have any two, but not all three at the same time. Once you internalise the trilemma, the entire stablecoin landscape — USDC, USDT, DAI, FRAX, USDe, GHO, crvUSD — collapses into a clean comparison matrix.

The Three Vertices

Decentralisation: no centralised issuer can freeze, censor, or undercollateralise the token at will
Capital efficiency: $1 of stablecoin requires close to $1 of locked capital — not $1.50 or $2.00
Stability: the stablecoin holds its $1 peg through normal market conditions and reasonable stress events

Centralised + Capital-Efficient (Sacrifices Decentralisation)

Examples: USDC, USDT, PYUSD — backed 1:1 by treasury bills and bank deposits at a regulated issuer
Strengths: cheap to issue, deep liquidity, banked rails
Weaknesses: issuer can freeze addresses (USDC routinely does for OFAC compliance), banking-system risk (Silicon Valley Bank moment)
Trade-off accepted: centralisation in exchange for capital efficiency and pegged stability

Decentralised + Stable (Sacrifices Capital Efficiency)

Examples: DAI (overcollateralised by ETH and other crypto), LUSD, GHO, crvUSD
Strengths: no central freezer, no banking-system tail risk, the stability mechanism is deterministic and on-chain
Weaknesses: requires 130-200% collateralisation — only ~$0.60-$0.75 of stablecoin per $1 of locked capital
Trade-off accepted: capital inefficiency in exchange for decentralisation and reliable peg

Decentralised + Capital-Efficient (Sacrifices Stability)

Examples: historical algo-stables (UST, BasisCash, FRAX-AMO before recapitalisation)
Strengths: 1:1 capital efficiency, no central issuer
Weaknesses: the peg breaks under stress — usually catastrophically (UST → $0 in 4 days)
Trade-off accepted: nominal stability in calm markets in exchange for fragility under stress
Note: this corner of the trilemma is the most dangerous — the peg works until it doesn't, and there is no backstop

Where USDe Fits

Ethena's USDe is the most interesting recent attempt to push closer to the centre of the trilemma: it uses delta-neutral perpetual hedges to maintain a peg with near-100% capital efficiency, while remaining substantially decentralised at the protocol layer. The trade-off it accepts is operational risk (the perp venues it hedges on must remain solvent and liquid) — a third axis the original trilemma did not name. The product works in 2026 but has not yet been stress-tested by a true crypto winter.

How to Use the Framework

Pick stablecoins by which trade-off you can absorb: USDC for maximum issuer-quality and deepest liquidity, DAI/LUSD for censorship-resistance, USDe for capital-efficient delta-neutral exposure. Never hold a stablecoin without knowing which two of the three vertices it has chosen — and never hold a stablecoin in the algorithmic-and-decentralised corner unless you understand exactly the stress conditions that have historically broken every member of that category.
