ERC-20 vs SPL-20: Which Network Is Better?
When it comes to moving money around in crypto casinos, not all token standards are created equal.
If you’ve played at even a handful of sites, you’ve probably noticed ERC-20 mentioned everywhere.
ERC-20, built on Ethereum, is the standard—trusted, familiar, and nearly everywhere.
But SPL-20, meanwhile, is Solana’s answer to fast, cheap transactions.
But is speed everything? Let’s dig into what really separates these two, where they shine, and where they still fall short.
🔑 Key Takeaways
- Over 90% of major crypto casinos accept ERC-20 for deposits and withdrawals, especially for stablecoins.
- Solana’s SPL-20 is a favorite for meme coins and low-fee trading, but casino support is still niche.
- USDT, USDC, and other stablecoins operate primarily on ERC-20, making it a safer pick for big deposits.
- Neither is perfect. ERC-20 can get expensive when gas spikes. If you’re betting small, or want to use Solana meme coins, SPL-20 has the edge for fees—but not for casino compatibility.
ERC-20 vs SPL-20: Comparison
Let’s look at how these two stack up in practice:
| Feature | ERC-20 (Ethereum) | SPL-20 (Solana) |
|---|---|---|
| Most Common Coins | Ethereum, USDT, USDC, DAI, SHIB, Polygon | SOL, USDT, BONK, TRUMP, JUP, WIF |
| Stablecoin Support | Yes (USDT, USDC, DAI, TUSD, etc.) | Yes (USDT, USDC, USDH, others) |
| Transaction Speed | 15–30 TPS (often slow) | 65,000+ TPS (ultra fast) |
| Typical Fees | $0.80+ (can spike) | Less than $0.01 (almost always) |
| Wallets | MetaMask, Trust, Ledger | Phantom, Solflare, Ledger |
| Casino Adoption | 90%+ of top crypto casinos | <1% |
| Network Congestion | Regular during peak | Rare, but not immune |
Is SPL-20 popular in crypto casinos?
Let’s be honest—SPL-20 isn’t exactly the go-to choice at most casinos.
The only mainstream site I’ve found with reliable SPL-20 support for USDT is BC.Game.
The vast majority of casino platforms still focus on ERC-20 tokens, since that’s where the biggest liquidity and safest, most predictable deposits happen.
That said, SPL-20 is seeing a bit of a meme coin boom.
If you want to gamble with $TRUMP, BONK, or some other Solana rocket ship, you’ll need SPL-20.
Bottom line? SPL-20 is fun for degen plays, but you’re still better off with ERC-20 for casino compatibility and stability—especially for anything involving real money and stablecoin casino gambling.
Can SPL-20 replace ERC-20?
Honestly, it’s not looking likely—at least in the short term.
More than 90% of all crypto casinos in our database work with ERC-20 tokens.
That’s where you’ll find all the big stablecoins (Tether, USDC, and more), and it’s still the default for anyone betting larger sums.
On top of that, the most popular gambling wallet, MetaMask, doesn’t support SPL-20.
Most stablecoin gamblers and high-rollers stick with ERC-20—it’s safer, better supported, and way less hassle if you ever run into a tech issue.
However, more and more casinos start to accept Solana as a payment method. So we can see a change sooner…or later.
What’s the future for both ERC-20 and SPL-20?
Here’s the elephant in the room—neither standard is perfect.
Gambling with Tether on ERC-20 is legendary, but it gets bogged down with high gas fees and congestion whenever the market heats up.
SPL-20 solves both problems with its lightning-fast, dirt-cheap transactions, but casino adoption just isn’t there.
BEP-20 (on Binance Smart Chain) is quickly finding middle ground. You get low fees, quick deposits, and, thanks to Binance, huge acceptance across the industry.
But even gambling with BEP-20 isn’t flawless: with the EU’s new MiCA regulations, Binance delisted Tether on their CEX for Europeans.
You can still use other blockchains for USDT and swap stablecoins on DEXes, but it’s a headache.
For now, ERC-20 is king for stablecoin deposits and withdrawals, but BEP-20 is gaining fast.
SPL-20 will probably keep growing among meme coin casinos—especially for quick, low-stakes bets.
Final words
ERC-20 has its flaws. High gas fees can make it painful for smaller gamblers, and during peak network activity, it’s far from the smoothest experience.
But if you’re moving serious money or want universal compatibility, it’s still your best bet.
If you’re after meme coin action, or just want to avoid Ethereum gas, SPL-20 is a killer option—especially for betting with Solana’s cult tokens like $WIF and $BONK.
Just don’t expect mainstream casino support… at least not yet.
As always, double-check network compatibility before you send a single coin.
