So Many Stablecoins, So Many Chains. Here’s How to Build on All of Them

This is 2025, we'll take for granted that you know what Stablecoins are, and if you don't, have a look at our previous guide!

‍
By the numbers

Stablecoins have quietly become the foundation of the crypto economy.

What started as a simple bridge for traders is now the engine of on-chain finance.

Today, over $305B in stablecoins circulate across public blockchains, and in Q3 2025 alone, on-chain transfers surpassed $15.6T, more than Visa’s quarterly settlement volume.

The recent GENIUS Act in the U.S. (signed July 2025) gave stablecoins their first federal framework.

It doesn’t solve everything, but it adds structure: clear reserve rules, transparency, and defined categories for issuers. For developers and institutions, it means more confidence building on-chain dollars.

From Trading Tools to Payment Rails

Stablecoins have evolved far beyond arbitrage or yield farming. They now power:

Cross-border payments and remittances where bank rails are slow or expensive

Treasury operations for DAOs, exchanges, and fintechs

Payroll and settlement for Web3 companies and creator platforms

Tokenization pilots for real-world assets (RWAs)

They’re programmable, instantly transferable, and in many corridors, cheaper to move than fiat.

And they’ve reached the point where the discussion isn’t if they stay, it’s which chains they live on.

Where stablecoins live, snapshot of where the money actually flows:

‍

Ethereum & Rollups - The Institutional Core

Ethereum remains the gravity center of on-chain dollars. Between mainnet and its rollups, it holds over $170B in stablecoin supply and moves roughly $2.8T per month.

Top tokens: USDC, USDT, DAI, GHO, PYUSD, crvUSD

New momentum: Regulated issuers like BlackRock (BUIDL fund), Ripple (RLUSD), and PayPal (PYUSD) all launched on Ethereum.

L2 traction: Arbitrum(~$10B), Base (~$4.6B), Optimism, and Polygon combine cheaper fees with EVM familiarity.

Use cases: Fintech settlements, tokenized deposits, and on-chain Treasury.

Solana - High-Speed Payments, Real Adoption

Solana is now a payment rail. With sub-second finality and fees measured in fractions of a cent, it’s attracting global settlement traffic.

Supply: ~$16B

30-day volume: ~$500B

Tokens: USDC, USDT, PYUSD

Milestones: Visa added Solana for USDC settlement; PayPal brought PYUSD here for consumer payments.

Use cases: In-app payments, micro-commerce, and real-time payroll.

Tron - The Retail Remittance Chain

Tron quietly dominates real-world usage. It handles $600B+ monthly in stablecoin transfers, mostly small-ticket remittances under $1,000.

Supply: ~$79B

Token: USDT accounts for more than 95% of circulation

Regions: Asia, MENA, Africa, Latin America‍

Why it matters: It’s become the de facto cross-border settlement rail for everyday users.

‍BNB Chain - Exchange Liquidity Hub

BNB Chain holds around $14B in stablecoins with roughly $60B monthly volume, powered by Binance integrations.

Top tokens: USDT, FDUSD

Profile: Exchange settlements, CEX-to-DEX transfers, and stablecoin swaps.

Region: Heavy in Asia and MENA corridors.

TON - Telegram’s Money Layer

Since Tether went live on TON in 2024, adoption exploded through Telegram wallets.

Supply: Several billion USDT and growing

Use cases: Peer-to-peer payments, in-chat commerce, and bot-based transfers.

Sui - The Move-Language Newcomers

With USDC natively available, Sui is courting fintechs and gaming apps needing safety plus speed.

Focus: In-app payments and Web3 game economies

Strength: Move’s resource model prevents double-spends and boosts security.

Cosmos via Noble & Stellar/XRP Ledger

Cosmos (Noble): USDC natively issued, used by interchain apps needing IBC transfers.

Stellar & XRP: Mature payment rails for NGOs and remittances, integrated with traditional FX providers.

New Entrants: Hyperliquid & Plasma

Hyperliquid: $5B+ stablecoin liquidity powering perps trading, backed by its own USDH.

Plasma: Launched in September 2025 with fee-free stablecoin transfers, $5B TVL in its first week, targeting emerging-market remittances.

Issuers & Momentum

- Tether’s supply continued to climb in 2025 and remains the dominant asset by circulation, with large shares on Ethereum, Tron, and BNB Chain. Q3 attestations show strong reserve income. Use this to explain why most retail rails still settle in USDT.

- USDC’s multichain footprint expanded again this fall, now native on 28 chains, which simplifies treasury routing and onramps for builders.

- PYUSD arrived on Solana, a clean proof point for mainstream payment flows choosing high throughput public chains.
