If you're new to crypto, you've probably seen the prompt "Choose Network: TRC20 or ERC20?" and panicked. This guide explains what those mean, when to use which, and why getting it wrong costs you money (or your entire balance).
TL;DR: For payments, transfers, and betting on Fish & Chips, always use TRC-20. It's cheaper, faster, and works the same as ERC-20 for everything you'd want to do with USDT outside of DeFi.
What "USDT" actually is
USDT is a stablecoin issued by Tether. Each USDT in circulation is supposed to be backed 1:1 by US dollar reserves. Tether issues USDT on multiple blockchains:
| Network | Symbol | Best for |
|---|---|---|
| Tron | TRC-20 | Payments, transfers, crypto gaming |
| Ethereum | ERC-20 | DeFi, smart contract interactions |
| BNB Chain | BEP-20 | BNB-ecosystem dapps |
| Solana | SPL | Solana NFTs/dapps |
| Polygon | Polygon ERC-20 | Cheap-Ethereum DeFi |
They're not interchangeable. USDT on Tron does not exist on Ethereum. They're separate tokens that happen to share a name. Sending TRC-20 USDT to an ERC-20 address means your funds land in a smart contract that doesn't recognise them — gone forever, no recovery.
The fee/speed comparison
| Action | TRC-20 (Tron) | ERC-20 (Ethereum) |
|---|---|---|
| Send 100 USDT | 1 USDT, 60 seconds | 5–25 USDT, 1–5 min |
| Send 10 USDT | 1 USDT, 60 seconds | 5–25 USDT, 1–5 min |
| Send 10,000 USDT | 1 USDT, 60 seconds | 5–25 USDT, 1–5 min |
The killer fact: Tron fees are flat. Send 10 USDT or 10,000 USDT, you pay 1 USDT. Ethereum fees scale with network congestion — sometimes 5 USDT, sometimes 25 USDT, occasionally 50+ USDT during NFT mints.
For a player making weekly deposits and withdrawals of 50–500 USDT, Tron saves you ~$50 a year minimum. For high-rollers, it can save thousands.
Why we picked TRC-20 for Fish & Chips
Three reasons:
- Predictable fees. Players know exactly what they'll pay. No "gas spike" surprises during peak network hours.
- Fast confirmations. 60 seconds means you can top up between crash rounds or arcade sessions without waiting.
- Mobile-first. TronLink is the cleanest mobile crypto wallet in 2026, hands down. MetaMask (Ethereum) is functional but rougher on mobile.
We may add ERC-20 support in late 2026 if Layer 2 fees drop sustainably. Until then, TRC-20 only.
How to know if your USDT is TRC-20
In your exchange wallet, USDT balances are usually listed with the network in parentheses: "USDT (TRC-20)" or "USDT (ERC-20)". On TronLink, all USDT is TRC-20 by definition — TronLink only supports the Tron network. If you're unsure, withdraw a small test amount first (5–10 USDT) and verify it arrives before sending more.
What about USDC?
USDC (Circle's stablecoin) works similarly: multiple networks, different addresses per network, same name. Fish & Chips doesn't accept USDC yet — only USDT TRC-20. Convert in your exchange before withdrawing.
To deposit: open fishnchips.io/wallet, connect TronLink, and send TRC-20 USDT. Arrives in ~90 seconds.
Frequently asked questions
What's the difference between TRC-20 and ERC-20?
TRC-20 is USDT on the Tron blockchain (1 USDT fee, 60s transfer). ERC-20 is USDT on Ethereum (5–25 USDT fee, 1–5 minutes). Same underlying token (Tether), different networks. They're not interchangeable — sending TRC-20 USDT to an ERC-20 address loses the funds.
Why would anyone use ERC-20 over TRC-20?
DeFi protocols on Ethereum (Aave, Uniswap, Curve) are far more numerous and trusted than Tron equivalents. If you're using USDT as collateral for lending or yield farming, you'll likely end up on ERC-20. For payments, transfers, and betting? TRC-20 wins by a wide margin.
Is TRC-20 safe?
Yes — Tether issues USDT on multiple networks, and TRC-20 has been live since 2019 with billions of dollars in volume daily. The Tron network has had occasional governance controversies but no successful attacks on USDT smart contracts.
Can I convert TRC-20 USDT to ERC-20 USDT?
Not directly on-chain — they're different networks. Use an exchange (Binance, Bybit, KuCoin): deposit your TRC-20 USDT, then withdraw to an ERC-20 address. Fee: 1 USDT in + ~5 USDT out = ~6 USDT round trip.
