How to connect to Polygon zkEVM via JSON-RPC — the Type 1 prover, equivalence testing, bridge architecture, and what makes it different from every other zkEVM. Includes production setup and fee optimization.
Read →Linea is a Consensys zkEVM L2 where standard eth_* just works — but gas estimation and finality have Linea-specific behavior worth knowing. A developer's guide.
Read →Scroll is a bytecode-equivalent zkEVM rollup (chain ID 534352) — it targets opcode-level equality with Ethereum, so your existing contracts, audits, and tooling work with zero changes, while ZK validity proofs give ~1-hour hard finality instead of the 7-day optimistic window. Standard eth_* (viem/ethers/foundry). Here's the developer map, including how it differs from zkSync Era.
Read →Taiko is a based rollup — Ethereum's own validators propose its blocks, so there's no sequencer to trust or to go down. It's also a Type-1 zkEVM, so your Ethereum tooling works bit-identically. Chain ID 167000, ETH gas, ~12s blocks. Here's what 'based' and 'Type-1' actually change for a developer.
