Switching chains after launch is a rebuild. Contracts, wallet integration, indexing, fee logic and often the product's economics all get rewritten, and whatever liquidity or users you had do not come with you. We looked for a public 2025 or 2026 migration with a published cost figure and found none, which tells you how rarely teams do it voluntarily.

We have run one end to end. A live Ethereum platform for tokenized reinsurance moved to Solana, and Token-2022 support came with the migration because the stablecoin the platform holds required it. That work is published with the client's name at our OnRe case study.

The one migration cost that is documented: Sherlock's 2026 pricing reference puts Rust and Solana audits at a 25 to 40 percent premium over Solidity, because the pool of qualified reviewers is smaller. Budget for that on any move toward Solana.

How we compare chains

Four criteria, in this order.

What the product cannot survive. A cost ceiling, a latency ceiling, or a guarantee it must have. This eliminates chains rather than ranking them, which is why it goes first.

Whose liquidity or users you need. If the product composes with existing protocols, or holds an asset that already lives somewhere, that somewhere is a strong default.

What you need to control. Fee token, transaction ordering, permissioning at the base layer. Most products need none of it.

What your team can operate at 2am. A chain your engineers cannot debug under pressure is a liability whatever its benchmarks say.

Our position on headline throughput numbers: they are measured under conditions your product will not reproduce. Solana's marketing figure of 65,000 TPS compares to a real non-vote average of about 1,300 in Q1 2026. Ethereum L1 does 15 to 26, and its L2s add around 227 on top. None of these numbers has ever decided an architecture we've built.

The comparison, September 2026

Ethereum L1. Best for institutional assets, protocols holding large value, and anything an institutional risk team must approve. Holds $49B of DeFi TVL (56%), $147B of stablecoins (48%) and $17.6B of tokenized RWA (45%). Median fee $0.03, simple transfer $0.01, swap $0.08. Real limit: fees are no longer the problem; the ceiling is throughput at consumer frequency. Developers: 31,869 active across the ecosystem including L2s (Jan to Sep 2025).

Ethereum L2 (Base, Arbitrum One, OP Mainnet). Best for consumer products that want EVM tooling and Ethereum settlement. Base secures $14.5B and Arbitrum One $12.8B; with L1 that is roughly 64% of all DeFi TVL. A Base transfer costs $0.0003, Arbitrum median $0.005. Real limit: every major L2 runs a single centralized sequencer, and bridges were 29% of 2026 exploit losses.

Solana. Best for consumer apps, trading, payments, and anything needing one global state at speed. Holds $5.9B of DeFi TVL (7%), $16B of stablecoins (5%) and $4.2B of RWA (11%, third place). Average non-vote fee about $0.01, and roughly 70% of user transactions pay a priority fee. Real limit: no full outage since February 2024, but a hosting fault on 12 August 2026 took 29% of stake offline against a 33% halt threshold. Developers: 17,708 active (Jan to Sep 2025), and audits cost 25 to 40% more.

Sources for every figure are listed at the end.

Choose Ethereum L1 if

Your product's value depends on assets or protocols that already live there. Institutional counterparties are involved and their risk teams want the most conservative option on the table. You want the widest choice of audit firms: Alchemy's directory lists 81 for Ethereum against 41 for Solana.

The old objection no longer holds. Ethereum L1 median fees are about three cents after the Dencun, Pectra and Fusaka upgrades, with a 60M gas limit and a simple transfer at a cent. The honest limit is throughput at consumer frequency, and that is what still pushes high-interaction products to the next column.

Choose an Ethereum L2 if

You want Ethereum's ecosystem and EVM hiring pool at sub-cent fees. This is the default for most EVM teams building something consumer-facing. Base and Arbitrum One between them hold about three quarters of L2 DeFi TVL, and both are Stage 1 on L2Beat, which means fraud proofs are live and a security council can only intervene with a supermajority.

Two things the pitch decks leave out. First, every major L2 still runs a single centralized sequencer; L2Beat lists one rollup with decentralized sequencing, Aztec, and none of the top ten. Second, bridges went from 1.4% of exploit losses in 2025 to 29% in the first eight months of 2026, most of it one incident where a compromised RPC fed a bridge configured with a single verifier. If your product depends on bridging, that configuration is your problem too.

On running your own rollup. Arbitrum Orbit supports a custom gas token and gives you your own sequencer; OP Stack removed custom gas token support in 2025, so plan on ETH for gas there. The app-chain thesis is working for products that bring their own distribution, such as Robinhood Chain, which went from mainnet in July to about 8% of all DEX volume in August, and above 15% on single days at month end. For everyone else the 2025 and 2026 record is a long list of shutdowns, and Arbitrum's own advice is now to launch on Arbitrum One first and migrate later if you outgrow it.

Choose Solana if

The product needs one global state at consumer speed rather than an island of its own. Consumer apps, anything with frequent small interactions, and trading products where latency is part of the experience all land here. Solana has led spot DEX volume every month of 2026, at 27 to 38% of the market, and slot time dropped to 350 milliseconds on 21 August.

Institutional adoption is real and recent. BlackRock's BUIDL fund sits about 34% on Ethereum, 33% on Solana and 20% on Avalanche, so Ethereum is the largest venue but no longer a majority. Western Union launched a stablecoin on Solana in May 2026, and Mastercard added it in June to a settlement list that also includes Ethereum, Base and Arbitrum.

Three honest costs. The account and program model differ enough from the EVM that a Solidity team needs a ramp, and audits cost 25 to 40% more. The network has had no full outage since February 2024, but on 12 August 2026 a routing fault at one hosting provider took 28.8% of stake offline for about half an hour against a 33.3% threshold that would have halted finality; an institutional risk team will know that number. And Token-2022 transfer hooks, often sold as the answer for permissioned assets, are initialized but inactive on PYUSD and on xStocks; no regulated issuer runs them in production, and the Solana Foundation now steers issuers to Token ACL and Default Account State instead. Plan on those, not on hooks.

What the numbers don't tell you

Neither virtual machine was the exploited layer in the two largest 2026 incidents. The $285M Drift loss on Solana was pre-signed transactions from a compromised administrative key. The $291M KelpDAO loss on Ethereum was a compromised RPC feeding a bridge configured with a single verifier. On both chains the first-half losses were dominated by keys and infrastructure, not program bugs: the Drift incident alone is roughly nine tenths of Solana's total, and Kelp is more than half of Ethereum's. Which chain is "safer" depends on which failure your team is more likely to make, and the answer is rarely the virtual machine.

Decentralization also cuts both ways. Solana's Nakamoto coefficient is about 10 by entity. On Ethereum, Lido and Coinbase together control roughly 30% of stake. Neither is the clean story its advocates tell.

Avoid multi-chain at launch

Our position: multi-chain on day one is a mistake for almost every product. Each chain multiplies contracts, audits, indexers, wallet paths and support surface, and you pay that multiple before knowing whether anyone wants the thing.

Ship one chain well. Expand when users ask, not when a roadmap slide does.

The part that decides it

Which constraint can your product not survive? Answer that and the chain usually picks itself.

Get it wrong and the bill arrives late. A migration is measured in quarters, and it lands at the moment you have users to keep and a roadmap you have already promised.

If you are also choosing who builds it, our guide on how to evaluate a Web3 development partner covers the questions to ask before you sign.

If you are weighing this now, or a build already feels like it landed on the wrong chain, a second opinion is the kind of call we take.

FAQ

Is it hard to switch blockchains after launch?

Switching is a rebuild. Contracts, wallet integration, indexing, fee logic and often the product's economics get rewritten, and liquidity or users on the original chain do not move with you. No public 2025 or 2026 migration has a published cost figure, which is itself a signal. The one documented cost is audits: Rust and Solana reviews run 25 to 40% above Solidity.

Should I build on multiple chains from the start?

Usually not. Each additional chain multiplies contracts, audits, indexers, wallet paths and support burden, and you carry that cost before knowing whether the product has demand. Ship one chain well, then expand when users ask for it.

Can an Ethereum developer build on Solana?

Not without a ramp. Solana uses a different account and program model, so Solidity experience does not carry over directly. Plan for the learning curve or bring in engineers who have already shipped on Solana, particularly for anything that holds funds, and budget for audits that cost 25 to 40% more.

Should I run my own rollup or build on an existing chain?

Build on an existing chain unless you bring your own distribution. The 2025 and 2026 record of app-specific rollups is a short list of successes with captive user bases and a long list of shutdowns, and Arbitrum itself now recommends launching on Arbitrum One first. If you do need your own chain, Arbitrum Orbit supports a custom gas token; OP Stack removed that support in 2025.

Is Solana still going down?

No full-cluster outage since 6 February 2024. The caveat: on 12 August 2026 a hosting-provider routing fault took 28.8% of stake offline for about half an hour, against a 33.3% threshold that would have halted finality. Uptime is real; physical-layer concentration is the risk the uptime number does not capture.
