Layer 1 and Layer 2 blockchains represent two distinct positions in the blockchain infrastructure stack — and their ICOs carry meaningfully different investment theses, tokenomics structures, and risk profiles. Understanding the infrastructure distinction helps evaluate whether a specific blockchain project's fundraise reflects genuine infrastructure value or speculative network narrative.
What Layer 1 ICOs Are
Layer 1 (L1) blockchains are base-layer networks that process and finalise transactions independently: Ethereum, Solana, Avalanche, Cosmos, NEAR, Aptos, Sui. An L1 ICO raises capital to build or grow a new base-layer blockchain. The investment thesis: the L1 network captures validator fees, ecosystem transaction value, and developer adoption that drives native token demand.
L1 ICO tokenomics pattern: Native token required for gas fees (creating real demand) + staking for network security (locking supply) + governance. Strong L1 tokens have both utility demand (gas) and staking supply sink. Risk: the L1 space is dominated by Ethereum and Solana — most new L1 ICOs face the fundamental challenge of displacing established networks with superior economics, security, or developer tooling.
What Layer 2 ICOs Are
Layer 2 (L2) networks build on top of existing L1s (primarily Ethereum) to scale throughput and reduce fees while inheriting L1 security: Arbitrum, Optimism, Base, zkSync, Polygon zkEVM, Starknet. L2 ICOs raise capital for teams building and growing L2 infrastructure. The investment thesis: L2 captures sequencer revenue, MEV, and ecosystem activity on top of Ethereum's security.
L2 ICO tokenomics pattern: Governance + sequencer fee sharing + ecosystem incentives. L2 tokens have weaker direct utility than L1 gas tokens — users pay gas in ETH on most L2s, not the L2 native token (ARB, OP are governance-only). Strongest L2 tokens add fee-sharing mechanisms (Velodrome on OP, Camelot on Arbitrum) or plan sequencer revenue share at governance level.
Investment Comparison
- Token demand mechanism: L1 tokens have gas requirement (real demand); L2 tokens are often governance-only (speculative)
- Network effects: L1 benefits from developer ecosystem lock-in; L2 benefits from Ethereum's existing developer base
- Competition: New L1s compete against Ethereum/Solana; new L2s compete against each other (many parallel chains)
- FDV at ICO: Both categories have historically launched at high FDVs — evaluate vs. stage-comparable protocols
- Failure risk: Most new L1s fail to achieve sufficient adoption; L2 adoption is growing overall but individual L2 token performance varies widely

Glossary
- Layer 1 (L1)
- A base-layer blockchain that independently processes and finalises all transactions — Ethereum, Solana, Avalanche are the leading examples.
- Layer 2 (L2)
- A scaling network built on top of an L1 (primarily Ethereum) that processes transactions off-chain and posts compressed proofs or data back to the L1 for final settlement.
- Sequencer
- The entity ordering L2 transactions before submitting them to L1 for settlement — a revenue-generating role that L2 protocols are gradually decentralising through governance.
