Your checkout page says Ethereum only. Your customer holds USDC on Solana. To pay you, they need to bridge to Ethereum: $0.50+ in gas, 10-15 minutes of waiting, and a bridge UI they may not trust. Most of them leave.
This is the single-blockchain problem. You built a payment flow that works on one network, and your customers live on five.
Stablecoin volume hit $33 trillion in 2025, according to Plasma Finance. That money does not sit on one blockchain. It is spread across networks based on cost, speed, and habit.
Here is where stablecoin supply concentrates today:
USDC recently flipped USDT in transfer volume, now accounting for over 50% of stablecoin transactions globally (ForkLog). But USDT still dominates in supply, and Tron still dominates USDT.
Your customers are split across these blockchains. If you only accept one, you are filtering out the rest.
Ethereum mainnet processes under 1.2 million transactions per day. Base handles roughly 7 million. Solana does 70 million. L2s like Base and Arbitrum are growing faster than Ethereum L1: Base TPS grew 51% recently, Arbitrum 17.5% (Binance). Solana, an L1 built for throughput, is pulling ahead of all of them in raw transaction count.
The reason is simple: fees and speed. But fees vary depending on whether you are sending a native asset (ETH, SOL, BNB) or a token (USDC, USDT). Token transfers cost more because they execute smart contract logic on top of the base transaction.
Tron deserves a closer look. Its reputation as the cheap USDT network comes from exchange withdrawals, where the exchange covers the contract execution fee. Sending TRC-20 USDT from a non-custodial wallet costs around $2 in energy/bandwidth fees. Most USDT on Tron lives in exchange wallets, not personal ones. Tron retains its volume through early adoption and exchange infrastructure, not because it is the cheapest option for end users.
A customer sending $50 in USDC picks Base or Solana. A customer sending $50,000 picks Ethereum for finality guarantees. A customer in Lagos with USDT on Binance withdraws via Tron because the exchange covers the fee. Each of these is a valid path. You need to accept all of them.
Sub-Saharan Africa processed over $205 billion in on-chain value between 2024-2025, growing 52% year-over-year (Chainalysis). Nigeria alone accounted for $92.1 billion.
The pattern here is distinct from the rest of the world:
Bitcoin dominates purchases. 89% of crypto purchases in Nigeria involve Bitcoin. 74% in South Africa. People use BTC as a store of value against currency devaluation and for cross-border remittances.
Stablecoins dominate payments. 43% of Sub-Saharan African crypto activity involves stablecoins (Chainalysis via RootData). When people pay for services, they pay in USDT or USDC. Tron is the default rail for USDT remittances across the continent.
Retail-sized transfers drive volume. Most transactions are under $10,000. Fee sensitivity is high. A $0.50 gas fee on a $100 Ethereum payment is 0.5% of the transaction. On Solana or Base, that same transfer costs under a cent.
If you are building payments infrastructure for African merchants, you need Bitcoin for store-of-value flows, Tron for existing exchange-based USDT liquidity, and low-fee networks like Solana, Base, and Arbitrum for the cost-sensitive majority.

The dominant blockchain for stablecoin payments is changing. Three years ago, Tron owned 36% of stablecoin transaction share. Today it holds 14.6% (ForkLog). Solana took the lead. Base is climbing.
Tron is not dead. $83.9 billion in USDT still lives there. But the growth is elsewhere. Solana processed 8.7 billion transactions in the last 30 days (CryptoSlate), roughly 70 million per day. Ethereum L1 does under 1.2 million.
For a payment processor, this means the blockchain mix of your customers is shifting under your feet. What worked 18 months ago will cost you conversions today.
A payer on Tron sends USDT. A payer on Base sends USDC. A payer on Bitcoin sends BTC. Your merchant sees one unified balance in USD.
The payment gateway handles:
The merchant never configures routing rules. The payer picks the blockchain they already hold assets on. Friction drops to zero.
Single-blockchain checkout creates three failure modes:
Bridge abandonment. The customer needs to move assets to your blockchain. Bridges are slow, expensive, and confusing. Many users abandon at this step.
Gas sticker shock. A customer on Ethereum L1 paying for a $10 service sees a $0.50 gas fee (5% surcharge). On Base, the same transaction costs $0.01.
Asset mismatch. Your checkout accepts USDC. Your customer holds USDT on Tron. Without multi-blockchain support, that customer cannot pay you at all.
Each of these is a lost conversion. Multiply across hundreds of daily transactions and the revenue impact compounds fast.
CoinCircuit supports Bitcoin, Ethereum, Solana, BSC, Tron, Base, and Arbitrum. Merchants accept BTC, ETH, USDT, USDC, SOL, BNB, TRX, and DOGE across these networks through a single API integration.
One POST /api/v1/payments call. The payer selects their blockchain and asset on the checkout page. Settlement normalizes into the merchant's fiat or stablecoin balance. No network management, no bridge configuration, no multi-wallet overhead.
Developer friendly API. Instant settlements. No hidden fees.
