Gitcoin Passport Stamps: ERC20 vs TRC20 — Which is Cheaper?

You need Gitcoin Passport stamps for on-chain analytics or DeFi bounties, but you don’t have a card or trust KYC. The fix? Pay with USDT on the right network. Here’s how ERC20 and TRC20 compare for stamp purchases in 2026.

Network Fees: The Hidden Cost

When you buy stamps via third-party sellers or direct Gitcoin integration, the blockchain fee matters. ERC20 requires Ethereum gas, currently averaging $2.50–8.00 per transaction. TRC20 uses Tron, with fees under $0.30. For a one-time stamp purchase (e.g., 10 stamps at $5 each), ERC20 adds 5–15% in gas, while TRC20 adds less than 1%.

Stamp Prices from Real Vendors

On Nansen.ai, a Gitcoin Passport stamp pack (5 stamps) costs $12.00 USDT ERC20. The same pack on Arkham Intelligence’s marketplace is $12.50 USDT TRC20. For Dune Analytics integrations, vendors like StampHub charge $8.00 USDT TRC20 for a single stamp. In all cases, TRC20 prices are slightly lower because vendors avoid Ethereum gas.

Speed Comparison

ERC20 transactions take 15–60 seconds on L1 (or 2–10 minutes if congested). TRC20 settles in 1–3 seconds. If you need stamps instantly for a time-sensitive airdrop or bounty, TRC20 wins.

USDT Payment Angle

Both networks use the same USDT token but on different chains. When paying, ensure your wallet holds USDT on the correct chain. Most vendors accept both, but TRC20 is cheaper for you. For example, buying 20 stamps on Dune via TRC20 costs you ~$40.60 (including fee), vs ~$48.00 on ERC20.

Our Recommendation

For cost-sensitive buyers (no card, KYC fear), TRC20 is the clear choice. The fee difference is 10x or more, and speeds are faster. Some vendors even offer a 5% discount for TRC20 payments. Always verify the vendor accepts TRC20, and use a reliable wallet like Trust Wallet or MetaMask with Tron support.

Verdict

If you’re paying in USDT for Gitcoin Passport stamps, go TRC20. It’s cheaper, faster, and avoids Ethereum’s gas headaches. Start your purchase now and save on fees.
