OpenAI API Credits: ERC20 vs TRC20 — Which is Cheaper?

If you're buying OpenAI API credits with USDT, the blockchain network you choose directly impacts your cost. TRC20 (Tron) and ERC20 (Ethereum) are the two most common standards, but they differ significantly in transfer fees, speed, and accessibility.

Why Network Fees Matter for API Credit Purchases

When you buy $100 worth of OpenAI API credits on our marketplace, you'll pay a network fee on top. For example, sending 100 USDT via ERC20 might cost $5–15 in gas fees, while TRC20 typically costs $0.50–$1. Over repeated purchases, those savings add up.

TRC20: Lower Fees, Faster Settlement

TRC20 transfers are processed in seconds with fees under $1. For instance, on January 15, 2026, sending 200 USDT via Tron cost just 0.65 USDT. This makes TRC20 ideal for frequent, smaller purchases of ChatGPT or Claude credits.

ERC20: Higher Fees, Wider Acceptance

ERC20 is more widely supported by exchanges like Binance and Coinbase, but gas fees fluctuate. On the same date, an ERC20 transfer of 200 USDT cost 8.40 USDT. It's better for large, one-time payments where the fee percentage is lower.

Which Should You Choose?

For most buyers, TRC20 is cheaper and faster. If your exchange only supports ERC20, consider converting to TRC20 before purchasing. Our marketplace accepts both, but we recommend TRC20 for savings.

Real Cost Comparison Example

Buying $500 in Midjourney credits: - ERC20: $500 + $12 gas = $512 total - TRC20: $500 + $0.80 gas = $500.80 total You save $11.20 per $500 — that's an extra 2% of credits.

No Card? No KYC? No Problem.

Our platform requires no KYC — just USDT via TRC20 or ERC20. After payment, get OpenAI API credits instantly for ChatGPT, Claude, Cursor, and Midjourney. Avoid bank delays and privacy concerns.

Final Verdict

TRC20 wins on cost for most users. But if you're moving large sums (over $10,000) from an exchange that only supports ERC20, the fee difference becomes negligible. For everyday AI subscription resale, stick with TRC20.
