Open-source CREATE2 vanity address grinder: search salts in the browser, check the address is unclaimed on every EVM chain, and deploy the same address on Ethereum, Base, Arbitrum and Robinhood Chain.
Grind a deterministic contract address by searching CREATE2 salts, in your browser, then check it is actually free on every chain before you deploy.
Try it without installing anything: npx wrangler deploy --temporary puts this whole thing (site, API and discovery documents) on a Cloudflare Workers URL in about thirty seconds and needs no account, no token and no configuration. That preview is disposable and gets a fresh subdomain every time; npx wrangler deploy with a Workers-scoped token puts it somewhere permanent.
A complete tool for deterministic deployments: the browser grinder, the site, an HTTP API, a CLI, an MCP server, cross-chain availability checks, a one-click deploy through the Arachnid proxy, and EIP-712 grind attestations whose central claim any verifier recomputes.
Four public inputs, one hash, twenty bytes out. No private key appears anywhere in that expression, and that single fact changes the whole risk model compared with a wallet grinder:
- a hostile grinder's worst case is a salt that does not work, disproved by one keccak; - the work can be delegated to anyone, on any machine, with nothing to protect; - server-side grinding is on by default here, because refusing to do it would be theatre (the wallet-side sibling, evm-vanity, disables its equivalent endpoint for exactly the opposite reason); - an attestation about the address is checkable, not merely signed.
Three things this does that other CREATE2 tools do not
