Which L2s connected to SOL now?

TLDR

Today, the active L2 connection to Solana is Bases new bridge to Solana, and early Solana?anchored L2 experiments like Sonami are emerging.

1. Base network: an official BaseSolana bridge launched using Chainlink CCIP, enabling SOL and SPL asset flows on Base apps announcement.
2. Sonami: a sponsored announcement positions it as a Solana Layer 2 with transaction bundling on L1 settlement press release.
3. Context: Solana historically runs a monolithic L1; Solana L2s are early and mostly bridges or experimental rollups.

Deep Dive

1. Base Bridge

Base, an Ethereum Layer 2, launched a native bridge integration to Solana using Chainlink CCIP.

1. The bridge lets Base apps support SOL and SPL assets, improving liquidity flow between the ecosystems BaseSolana bridge.
2. Chainlink CCIP adds a multi?validator model for cross?chain messages, addressing common bridge security concerns, per the announcement above.
3. Several Base apps are integrating Solana assets, signaling a practical path for user flows across both networks coverage.

2. Sonami L2 Claim

Sonami publicized a Layer 2 token on Solana using transaction bundling that settles back to Solana L1.

1. The project frames bundling as a congestion relief valve during peak activity (memecoins, mints, rapid DEX trading) press release.
2. The release describes an intent to group interactions off?chain, then commit to L1 for throughput and consistency, but is promotional and not an audited network report additional coverage.
3. Treat as early stage until independent documentation and validation arrive. Sponsored posts are marketing, not technical audits.

3. Solana L2 Reality Check

Solanas design has focused on single?chain performance rather than an Ethereum?style L2 stack.

1. The newest activity is hybrid: bridges that connect Solana to L2s elsewhere (Base) and early L2?like models that still settle on Solana (Sonami), with limited neutral validation bridge note.
2. Parts of the media now label anything off?chain plus L1 settlement as L2, but architectures vary. Scrutinize settlement, data availability, and security models before treating them as L2 equivalents.
3. Expect more SVM?based or settlement?to?Solana designs to surface, but confirmation via code, audits, and uptime will be key.

Conclusion

Right now, Solanas clearest connection to an L2 is Bases new bridge, which enables practical SOL and SPL flows into EVM apps. Claims of native Solana L2s are emerging but remain early and largely promotional. The near?term opportunity is cross?ecosystem liquidity via the Base bridge, while true Solana?settled L2s will need time and third?party validation to prove reliability and security.
