Global DeFi TVL crossed $100 billion in 2025. Southeast Asia accounts for an outsized share of on-chain activity for its GDP size — and three countries in the region are growing faster than every global market except the United States.

The DeFi conversation in most Western media is dominated by Ethereum yield protocols, US institutional capital, and protocol governance debates. That framing misses where the actual user growth is happening. Southeast Asia’s DeFi adoption is not driven by institutional treasury management. It is driven by populations who are simultaneously under-banked and hyper-connected — people who have smartphones but not savings accounts, who trade on-chain because the alternative is a bank branch that closes at 4pm and charges 2 percent for a domestic transfer.

This distinction matters for anyone allocating capital into the region, building crypto-adjacent products, or trying to understand where the next wave of DeFi users comes from. The five markets below are not famous in crypto Twitter. They are significant in the only metric that matters over the next decade: user volume, transaction count, and on-chain capital formation by people for whom DeFi is not a financial toy but a financial necessity.

Southeast Asian DeFi growth has its roots in the 2020–2021 play-to-earn cycle, when Axie Infinity (Philippines), STEPN (global but heavily adopted in SEA), and similar protocols introduced millions of users to wallet management, token swaps, and yield concepts without those users ever identifying as “DeFi participants.” The muscle memory was built through gaming. The migration to financial DeFi — lending, borrowing, stablecoin farming, perpetuals — came after.

The region’s second accelerant was stablecoin demand. In countries where local currency volatility creates real purchasing power risk — the Philippine peso fell 8 percent against the dollar in 2024 alone — USDC and USDT are not speculative assets. They are savings instruments. The DeFi protocols that offer yield on stablecoin holdings are, for many users, the most rational place to park discretionary savings.

DeFi adoption in SEA splits into two layers. The first is DEX trading — mostly on Ethereum mainnet, Binance Smart Chain, and Solana — where users access spot markets without KYC, often funded through P2P USDT on-ramps. The second is DeFi-native financial activity: lending on Aave, Compound, and Venus; liquidity provision on Uniswap and PancakeSwap; and perpetual derivatives trading on GMX, dYdX, and Blofin’s on-chain instruments.

The five markets seeing the strongest growth patterns in 2026 are:

Philippines. The largest English-speaking crypto user base in Southeast Asia. Chainalysis consistently ranks the Philippines in the top 10 globally. DeFi here runs heavily through BSC, driven by lower gas costs relative to Ethereum mainnet. GCash integration with certain DEX protocols has created a more frictionless fiat-to-DeFi pipeline than anywhere else in the region.

Vietnam. As documented in our companion article on crypto adoption, Vietnam’s 17 million crypto users are increasingly sophisticated. DeFi activity is growing faster than CeFi activity — the absence of licensed exchanges pushes users toward decentralized protocols, particularly for lending and stablecoin yield.

Indonesia. Institutional DeFi is earlier-stage here, but retail DeFi on BSC and Polygon has grown significantly since Indodax and Tokocrypto introduced their user bases to on-chain concepts. With GoTo’s GoPay integrating more aggressively into digital finance, the wallet infrastructure for DeFi on-ramps is improving rapidly.

Thailand. Often overlooked, Thailand has one of the most sophisticated retail trader communities in ASEAN. The Securities and Exchange Commission has moved faster on crypto regulation than most regional peers, creating a paradoxically healthy DeFi ecosystem — regulated exchanges teach users the concepts, and users migrate to DeFi for the products that regulated platforms cannot offer.

Malaysia. The Securities Commission Malaysia’s regulatory framework has created a licensed exchange ecosystem, but DeFi adoption is growing in parallel, particularly among the Malaysian Chinese community with cross-border capital ties to Singapore and Hong Kong.

Global DeFi TVL as tracked by DefiLlama stood at approximately $100 billion in early 2025, recovering from the 2022 bear market cycle. Stablecoin supply across all chains tracked by DefiLlama reached approximately $310 billion by 2026 — a proxy for the capital available to DeFi systems.

For SEA specifically: Chainalysis’s 2024 index placed four SEA countries in the global top 20 for on-chain activity (Philippines, Vietnam, Indonesia, Thailand). Combined, these four markets represent an estimated 60 to 80 million crypto users — more than the entire population of France. If even 10 percent are active DeFi users, that is 6 to 8 million people generating on-chain transactions, providing liquidity, and paying protocol fees. At average on-chain activity of US$500 per user per quarter, that is US$3 to 4 billion in quarterly DeFi volume from SEA alone.

The bear case is not about user count — it is about user quality. SEA DeFi adoption is heavily concentrated in low-value, high-frequency transactions. The average transaction size from Vietnamese or Filipino P2P users is materially smaller than from South Korean or European DeFi participants. Protocol revenue, which drives token valuations and developer incentives, is a function of fee volume — not transaction count. A market with 10 million users making $50 transactions generates less protocol revenue than one with 100,000 users making $5,000 transactions. SEA’s DeFi story is a user acquisition story. The monetization story is still being written.

The regulatory tailwinds in 2026 are actually running in DeFi’s favour in Southeast Asia — an unusual reversal of the global pattern. As governments in Vietnam, the Philippines, and Indonesia build licensing frameworks for centralized exchanges, they simultaneously create a more educated user base that migrates to DeFi for the products regulators cannot permit. CeFi regulation in EM markets functions as a DeFi on-ramp.

For traders in the region, the products that will define this cycle are not spot DEXs. Those are commoditized. The growth products are on-chain perpetuals (where Blofin and GMX are competing for the derivatives-literate SEA trader), real-world asset (RWA) protocols tokenizing ASEAN government bonds and property, and cross-chain bridging that makes multi-chain DeFi accessible through a single mobile interface. The infrastructure is being built in 2025 and 2026. The users are already there.
