Real stablecoin payments are growing, but the logic for choosing a chain is different from what you might think—the fastest or cheapest chain is not always the best fit for your settlement business. Companies should not choose a chain by TPS rankings. Instead, they should look at which chains their suppliers accept and which compliance rails are supported.
The data behind real payment growth
In 2025, total stablecoin on-chain transaction volume reached $33 trillion, already more than Visa ($18 trillion) and Mastercard ($12.5 trillion) combined. But the part that is truly 'real payments' is estimated by a16z researchers at about $350–550 billion, or 1–2% of the total. This is still growing quickly—consumer-to-business (C2B) stablecoin transaction volume grew 128% year over year in 2025, reaching 284.6 million transactions.
Nearly two-thirds of stablecoin payment volume comes from Asia (mainly Singapore, Hong Kong, and Japan), about one-quarter from North America, and about 13% from Europe. This distribution itself shows that the 'best chain' depends on where you do business.
Key factors for enterprise settlement
To judge whether a chain is suitable for enterprise settlement, focus on four things: fee structure, confirmation speed, compliance support, and ecosystem coverage.
| Factor | What enterprises need |
|---|---|
| Fees | Low and predictable, not cheap sometimes but many times higher during gas spikes |
| Confirmation speed | How fast a transaction becomes irreversible—not just block time, but finality time |
| Compliance support | Whether institutions like Visa/Mastercard have connected to this chain's settlement rails |
| Ecosystem coverage | Which chains your suppliers and customers use; the more chains you support, the faster the match |
How different chains compare
Solana
Fees are very low and predictable. Network fees are a tiny share of the end-to-end stablecoin cost. When the Bank of Italy tested 200 USDC cross-border transfers, blockchain fees were only a small part of total cost. The real cost pressure was in conversion and cash-out.
For confirmation, Solana reaches consensus confirmation within 800 milliseconds, with final confirmation in about 13 seconds. Visa's stablecoin settlement pilot already supports Solana.
Base
Base is operated by Coinbase. A single transaction costs far less than $0.01. It uses a centralized sequencer and gives near-instant pre-confirmation (2-second block time), but true finality takes about 15 minutes because settlement happens on Ethereum.
Base handles 54% of USDC transfers, more than all other blockchains combined. Its on-chain stablecoin supply is $3.62 billion. Visa has connected to Base's settlement rails.
Polygon
After Polygon's Giugliano hard fork, finality confirmation time dropped to about 4 seconds, with a target of 1,000 TPS. Per-transaction fees remain sub-cent. 34% of dollar stablecoin transfers happen on Polygon, with 178 million stablecoin transactions in March. Visa has connected to Polygon.
Plasma (a stablecoin-specific chain)
Plasma is a stablecoin-focused Layer 1 supported by Tether. Its key selling point is 'free transfers'—users do not need to hold a platform token or pay extra gas when sending USDT; the chain covers the cost. It uses PlasmaBFT consensus, with stable block times and final confirmation.
It currently targets cross-border payments, merchant settlement, and fintech. It is bridged to Bitcoin and is EVM-compatible.
Recommendations for different business scenarios
Scenario A: Your suppliers are mainly in Latin America/Asia and accept USDT → Consider Tron (the largest real payment volume) or Plasma (free transfers). Tron is often overlooked, but USDT payment volume on Tron is still mainstream.
Scenario B: You run U.S. compliance-focused business and accept USDC → Choose Solana or Base. Both are officially connected to Visa settlement rails, with low cost, fast speed, and clear compliance frameworks.
Scenario C: Your business spans multiple chains and you don't want to be locked into one → You don't need to choose one. Use Visa's multi-chain settlement rails. Visa has connected to 9 blockchains (Avalanche, Ethereum, Solana, Stellar, Arc, Base, Canton, Polygon, Tempo). Enterprises only need to connect to Visa's settlement layer; the underlying chain is decided by partners.
Scenario D: You make localized payments in Asia, such as Singapore or Hong Kong → Look at local solutions like the Hong Kong dollar stablecoin HKDAP. Fireblocks expects mid-sized enterprises to be the main growth driver for stablecoin B2B settlement, and as Hong Kong is an Asian payment hub, demand for local stablecoins is rising.
Important warning
The Bank of Italy's real-world test shows that blockchain fees are only a very small part of total cost. The real difference is in conversion and cash-out. If you choose a chain with very low gas fees, but your supplier's cash-out channel adds a 2% exchange rate markup, the gas savings are completely eaten up. Before choosing a chain, look first at your supplier's cash-out channels and local payment networks, then at the chain itself.
Quick checks before you choose
Next week, pick a real payment you need to make:
Ask your supplier: 'Do you accept USDC? Which chain do you use?'
If the supplier doesn't know or has no fixed chain, choose Base or Solana—Visa is already connected, and both cost and compliance have been tested.
If the supplier is in Asia and accepts USDT, consider Plasma or Tron.
Verification tip: Use the cross-chain payment cost comparison tool at three.ws to check the current real-time gas premium on Solana and Base, and decide which chain is more cost-effective.
