Financial Services Are Being Rebuilt on Distributed Ledger Technology
Blockchain-based financial products processed more than $15 trillion in combined transaction volume in 2024, according to Chainalysis. That includes on-chain payments, decentralised finance (DeFi) protocols, tokenised securities, and stablecoin transfers. The figure has grown roughly 5x since 2020, reflecting a rapid shift from speculative cryptocurrency trading toward practical financial applications built on blockchain infrastructure.
Boston Consulting Group projects that 10% of global GDP will be stored or transacted on blockchain by 2030. That estimate accounts for tokenised assets, stablecoin-based payments, on-chain lending, and blockchain-based trade finance. The broader digitisation of financial services is creating conditions where blockchain-based alternatives can compete with and in some cases outperform legacy systems.
Stablecoins Have Found Product-Market Fit
Stablecoins — digital tokens pegged to fiat currencies — reached a combined market capitalisation of $190 billion in early 2025, according to CoinGecko. Tether (USDT) and Circle (USDC) dominate the market, but new entrants including PayPal’s PYUSD are growing rapidly. Stablecoins process more than $30 billion in daily transaction volume, a figure that rivals major traditional payment networks.
The use case is clear: stablecoins enable instant, low-cost transfers of dollar-denominated value anywhere in the world. A business in Nigeria can receive payment from a US supplier in minutes rather than days, at a fraction of the cost of a wire transfer. Fintech platforms are integrating stablecoin payments into their services, and traditional financial institutions are following. Visa, Mastercard, and PayPal all now support stablecoin transactions on their networks.
Decentralised Finance Is Maturing
DeFi protocols held $180 billion in total value locked (TVL) at the start of 2025, according to DeFi Llama. The largest protocols — Aave, Lido, MakerDAO, and Compound — operate lending, borrowing, and staking services without traditional intermediaries. Aave alone has originated more than $50 billion in loans, with default rates well below traditional banking averages due to its over-collateralisation model.
Institutional DeFi is a growing category. McKinsey reports that more than 30 major financial institutions are now using DeFi protocols or building permissioned versions for their own operations. JPMorgan tested cross-border DeFi transactions through Project Guardian with the Monetary Authority of Singapore. Blockchain startups like Maple Finance and Centrifuge are building DeFi lending products specifically designed for institutional borrowers.
Programmable Finance Creates New Possibilities
Smart contracts enable programmable finance — financial transactions that execute automatically when specific conditions are met. This capability opens possibilities that traditional financial infrastructure cannot support. An insurance policy can pay out automatically when a flight is delayed, using data from an airline’s API. A trade finance transaction can release payment automatically when shipping documents are verified on-chain.
Chainlink, the leading oracle network, provides the real-world data feeds that smart contracts need to interact with external systems. More than 1,800 DeFi protocols use Chainlink to connect on-chain logic to off-chain data. Accenture estimates that programmable finance could automate 30% of financial back-office operations by 2030, saving the industry billions in processing costs.
Regulatory Frameworks Are Taking Shape
The EU’s Markets in Crypto-Assets (MiCA) regulation, which took full effect in 2024, created the world’s first comprehensive regulatory framework for blockchain-based financial products. The UK published its own framework in 2024. Hong Kong, Singapore, and Dubai have established licensing regimes for digital asset businesses. The US is advancing stablecoin legislation through Congress.
Fintech venture funding in blockchain has accelerated as regulatory clarity improves. Investors are more willing to fund blockchain financial infrastructure when there is a clear regulatory path to operation. The combination of maturing technology, proven use cases, and developing regulatory frameworks positions blockchain innovation as one of the most significant forces reshaping financial services globally.
