The Stablecoin Landscape
Today there are dozens of USD-pegged stablecoins: USDT, USDC, BUSD, DAI, PYUSD, and more — each available on multiple chains. For a payment platform, picking the right combination matters enormously.
Why USDT?
Tether (USDT) is by far the most liquid stablecoin globally. With over $100 billion in market cap and daily trading volumes exceeding all other stablecoins combined, USDT is the stablecoin your customers are most likely to already hold.
Liquidity also means your customers can acquire USDT easily from any major exchange, peer-to-peer platform, or on-chain swap — reducing friction at checkout.
Why BNB Smart Chain?
BNB Smart Chain offers the right balance of cost, speed, and adoption:
- Transaction fees: typically $0.01–0.05, vs. $1–50 on Ethereum
- Block time: ~3 seconds, giving near-instant confirmations
- Ecosystem: large user base in Asia and emerging markets where crypto adoption is highest
- Tooling: EVM-compatible, meaning existing Solidity and ethers.js tooling works without modification
The USDC Trade-Off
USDC is more regulated and transparent than USDT, which matters for some use cases. However, USDT's liquidity advantage on BNB Chain is significant — USDT/BNB trading pairs have 5–10× the volume of USDC/BNB pairs on PancakeSwap.
What About Multi-Chain Support?
Paychainly is architected to support additional chains and tokens. The block pipeline is chain-agnostic — swapping the RPC URL, token contract address, and chain ID is the primary change required. Multi-chain support is on the roadmap.
Our Recommendation
For most merchants targeting global customers, USDT on BSC is the optimal choice today. Start there — adding USDC or other chains is possible later once volume justifies the operational complexity.
