English — A stablecoin aims to hold a fixed value, usually $1, via fiat, crypto, or algorithmic backing — but the peg is only as strong as the design behind it.
Português — Uma stablecoin procura manter um valor fixo, normalmente 1$, com lastro em fiat, cripto ou algorítmico — mas o peg é tão forte quanto o design por trás dele.
Español — Una stablecoin busca mantener un valor fijo, normalmente 1$, con respaldo fiat, cripto o algorítmico — pero el peg solo es tan fuerte como el diseño que lo sostiene.
Français — Un stablecoin vise à garder une valeur fixe, souvent 1 $, via un adossement fiat, crypto ou algorithmique — mais l'ancrage ne vaut que le mécanisme qui le soutient.
Deutsch — Ein Stablecoin soll einen festen Wert halten, meist 1 $, gedeckt durch Fiat, Krypto oder Algorithmus — doch der Peg ist nur so stark wie sein Design.
Русский — Стейблкоин стремится держать фиксированную стоимость, обычно 1$, за счёт фиатного, крипто- или алгоритмического обеспечения — но привязка крепка лишь настолько, насколько крепка её конструкция.
Türkçe — Stablecoin sabit bir değeri, genelde 1$, fiat, kripto ya da algoritmik teminatla korumayı amaçlar — ama sabitleme yalnızca ardındaki tasarım kadar güçlüdür.
العربية — العملة المستقرة تسعى لقيمة ثابتة، غالباً دولار واحد، بضمان نقدي أو مشفّر أو خوارزمي — لكن الربط بقوة التصميم الذي يسنده فقط.
हिन्दी — स्टेबलकॉइन एक स्थिर मूल्य, आमतौर पर $1, बनाए रखने का लक्ष्य रखता है — फिएट, क्रिप्टो या एल्गोरिद्मिक बैकिंग से; पर पेग उतना ही मजबूत जितना उसका डिज़ाइन।
日本語 — ステーブルコインは通常1ドルの固定価値を、法定通貨・暗号資産・アルゴリズムの裏付けで保とうとしますが、ペッグは背後の設計次第の強さです。
中文 — 稳定币旨在维持固定价值（通常 1 美元），靠法币、加密或算法背书——但锚定的牢固程度取决于其背后的设计。
한국어 — 스테이블코인은 보통 1달러의 고정 가치를 법정화폐·암호화폐·알고리즘 담보로 유지하려 하지만, 페그는 그 뒤 설계만큼만 견고합니다.
Bahasa Indonesia — Stablecoin bertujuan menjaga nilai tetap, biasanya $1, lewat jaminan fiat, kripto, atau algoritmik — tapi peg hanya sekuat desain di baliknya.
বাংলা — স্টেবলকয়েন সাধারণত $১-এর একটি স্থির মান ধরে রাখতে চায় — ফিয়াট, ক্রিপ্টো বা অ্যালগরিদমিক সমর্থনে; কিন্তু পেগ ততটাই শক্ত যতটা এর পেছনের ডিজাইন।
Filipino — Layunin ng stablecoin na panatilihin ang nakapirming halaga, kadalasang $1, sa pamamagitan ng fiat, crypto, o algorithmic na suporta — pero kasinlakas lang ng disenyo nito ang peg.
A stablecoin is a token engineered to stay at a fixed price, almost always one US dollar. It is the unit people park in between trades, price pairs against, and move across chains without touching a bank. But "stable" is a goal, not a guarantee — the peg holds only as long as the mechanism behind it does, and the mechanisms differ enormously.
Fiat-backed coins (like USDC) hold real dollars and bonds in reserve, one per token, redeemable — the peg is a custodian's promise you can verify through attestations. Crypto-backed coins (like DAI) lock surplus crypto as collateral, over-collateralised so a price drop does not immediately break them. Algorithmic coins try to hold the peg with supply rules and arbitrage incentives, and no hard backing.
Why pegs break
A peg is only as strong as the weakest link in its design. Fiat-backed coins depend on the reserves being real and reachable — a scare about the custodian can knock the price off a dollar until confidence returns. Crypto-backed coins depend on the collateral staying above the debt — a violent crash can undercollateralise them. Algorithmic coins depend on unbroken confidence, and history has some catastrophic failures when that confidence snapped and the supply mechanism spiralled.
Practical takeaway: not all "stable" coins are equally safe, and the peg you rely on is a design you should understand before parking real money in it. Prefer transparent, well-collateralised designs, watch for a coin trading persistently off its peg, and remember that on-chain, liquidity depth still decides how cleanly you can actually swap in and out.

Every claim above is checkable against the chain. Start here:
a fiat-backed stablecoin should trade at ~1.00 — quote it against another stable in the app; a persistent gap from parity is the market pricing in peg riskContracts are verified on every chain we deploy to — addresses in the protocol manifest. Deeper formal treatment: the whitepaper (PDF).
