zkSync Era

zkSync Era, chain 324. zksync-era resolves as an alias and zkSync Era as the display name.

Address format

The EVM format, shared by every EVM chain here: 0x and 40 hex digits, any case. An address that fits zkSync Era fits the other thirteen EVM chains too, and identify says so rather than picking one. The EIP-55 checksum, the one carried in letter case, is verified where there is one: mixed case has to match the hash, and an address in one case throughout passes, since it carries no checksum.

import { getChain } from "@agntn/chains";

chain.assertAddress("0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984"); // returned unchanged
chain.chainId; // "0x144"
chain.caip2; // "eip155:324"
