| **Best For** | Speed & low cost | Maximum compatibility |

What Are These Token Standards?

ERC-20 (Ethereum Request for Comment 20)
The granddaddy of token standards, introduced in 2015. ERC-20 defines a common set of rules for tokens on Ethereum, enabling:
- Standardized token transfers
- Balance checking
- Token approvals for smart contracts
- Compatibility across all Ethereum wallets and dApps

**Examples:** USDT, USDC, UNI, LINK, SHIB, PEPE

SPL Token (Solana Program Library Token)
Solana's token standard, introduced in 2020. SPL tokens are built using the Token Program and offer:
- High-speed transfers
- Low transaction costs
- Native Solana integration
- Advanced features like Associated Token Accounts

**Examples:** USDC (SPL version), BONK, PYTH, JTO, WIF

Detailed Comparison

1. Transaction Speed

**SPL Token (Solana):**
- **Block time:** ~400 milliseconds
- **Finality:** ~400ms (single slot confirmation)
- **Real-world speed:** Near-instant in wallets

**Example:**
Swapping tokens on Jupiter (Solana DEX) typically completes in under 1 second from confirmation to balance update.

**ERC-20 (Ethereum):**
- **Block time:** ~12 seconds
- **Finality:** 12-30 seconds (2-5 block confirmations)
- **Real-world speed:** 1-5 minutes for full confidence

**Example:**
Swapping tokens on Uniswap requires 12 seconds per block, with most apps waiting for 2-5 confirmations (24-60 seconds).

**Winner:** SPL Token (30-75× faster)

**Use case impact:**
- **Gaming:** Solana's speed enables real-time in-game transactions
- **DeFi:** Faster arbitrage and trading opportunities on Solana
- **Payments:** Solana feels like Web2; Ethereum still feels like crypto

2. Transaction Costs

**SPL Token (Solana):**
- **Average transaction:** $0.00025 (~5,000 lamports)
- **During congestion:** $0.001-0.01 (with priority fees)
- **Token creation:** $2-10 including metadata

**Real-world example:**
- 100 token transfers: $0.025 on Solana
- Creating + distributing tokens to 1,000 wallets: ~$2.50

**ERC-20 (Ethereum):**
- **Average transaction:** $1-5 (during low activity)
- **During congestion:** $10-100+ (can reach $200+ during peak)
- **Token creation:** $50-1,000 depending on gas prices

**Real-world example:**
- 100 token transfers: $100-500 on Ethereum
- Creating + distributing tokens to 1,000 wallets: $10,000-50,000

**Winner:** SPL Token (100-1,000× cheaper)

**Use case impact:**
- **Airdrops:** Solana enables mass distribution; Ethereum makes it prohibitively expensive
- **Microtransactions:** Only viable on Solana
- **User onboarding:** Solana users don't need huge ETH balances for gas

3. Scalability & Throughput

**SPL Token (Solana):**
- **Theoretical max:** 65,000 transactions per second (TPS)
- **Actual performance:** 3,000-5,000 TPS sustained
- **Parallel processing:** Transactions process simultaneously

**Network capacity:**
Solana can theoretically handle every Visa transaction globally in real-time.

**ERC-20 (Ethereum):**
- **Base layer:** 15-30 TPS
- **With Layer 2s:** 2,000-4,000 TPS (Arbitrum, Optimism, Base)
- **Sequential processing:** Transactions process one by one

**Network capacity:**
Base Ethereum handles roughly the same TPS as a single credit card terminal.

**Winner:** SPL Token (1,000-4,000× higher throughput on L1)

**Important note:** Ethereum Layer 2 solutions significantly improve scalability but add complexity (bridging, multiple networks, fragmented liquidity).

4. Developer Experience

**Savings with Solana:** $23,997-119,997 annually

Scenario 3: DeFi Project with Daily Trading

**ERC-20 (Ethereum):**
- 1,000 daily swaps: $2,000-10,000 in user gas fees
- Users pay more → less trading → less liquidity

**SPL (Solana):**
- 1,000 daily swaps: $0.25 in user fees
- Users trade more → more liquidity → better price discovery

Migration: Should You Switch?

Consider migrating from ERC-20 to SPL if:
✅ Gas fees are preventing user adoption
✅ You need high-frequency transactions
✅ Your project involves gaming, NFTs, or micro-payments
