Choosing the Right Blockchain for Your Product
"Which chain should we build on?" is really five questions: what do transactions cost, how fast do they finalize, how mature is the tooling, where is the liquidity — and where are your users?
Ethereum remains the settlement layer of choice when guarantees matter most: deepest liquidity, best tooling, most auditors. The price is fees, which is why most user-facing activity now lives on L2s. For consumer apps we default to Base or Arbitrum depending on the use case; for high-frequency DeFi, Arbitrum's liquidity usually wins.
Polygon earns its place for low-fee, high-volume applications like credentials and registries — ProofPass issues there for fractions of a cent. Solana enters when throughput dominates everything else, as with OrbitPay's payment routes, with the honest caveat of a different development model your team must staff for.
Our decision worksheet scores each candidate on fees at your expected volume, finality your UX can tolerate, wallet penetration in your user base, oracle and infra support, and exit options if you need to migrate. Multi-chain abstraction keeps that migration a configuration change rather than a rewrite.
The most expensive mistake is choosing by narrative. Run the numbers for your transaction profile, talk to teams running production load on your shortlist, and pick the chain your users already have wallets on.
