Open-source EVM vanity wallet generator: grind a 0x address in your browser, delegate hard patterns with secp256k1 split-key grinding that cannot expose your key, and verify EIP-712 provenance attesta
View on GitHub ↗Homepage ↗Grind an EVM address that starts or ends with characters you choose, in your browser, across every core, with an honest account of what it costs.
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 vanity wallet stack for Ethereum, Base, Arbitrum, Robinhood Chain and every other EVM network: the browser grinder, the site, an HTTP API, a CLI, an MCP server for AI assistants, EIP-712 provenance attestations a contract can verify, and a delegation protocol that lets somebody else do the work without ever being able to compute your key.
1. Entropy, which is the only thing that has ever mattered here
In 2022 the most popular EVM vanity generator seeded its search from a 32-bit value. Every key it had ever produced became searchable and tens of millions of dollars were drained. This grinder draws a full 256-bit base scalar from the platform CSPRNG, re-seeds every million candidates so no run extends one arithmetic progression indefinitely, and re-derives every match through a separate code path before emitting it. A key that does not control the address it matched is never returned; there is a test for that.
