The walletlink.social icon: a brown leather wallet with an Ethereum diamond embossed on it and three colourful profile cards tucked inside.

walletlink.social

Tool

Upload a CSV of Ethereum addresses and get back the Twitter and Farcaster accounts behind them, ranked by who is actually worth reaching first.

How it started

it started because my colleagues asked if it was possible to look up social profiles for holders of our product.

i did some research, ran some tests and that led to eventually creating a tool for my colleagues and then iterating and improving it, realizing the value it had just for us.

A Slack thread from January 2026: Jake tells the team he has the API keys he needed, so he built an app they can use, with a link to the first version and a screenshot of its results.
The thread it came out of, January 2026.
walletlink.social open on a MacBook, showing the drop zone for a file of Ethereum addresses and a Recent Activity row of past lookups, each reporting socials found, the Twitter and Farcaster split, and a hit rate.
Recent lookups, each reporting how many socials were found and the hit rate across the batch.

What it does

Batch lookup
Drop in a list of addresses and it resolves the whole set at once, aggregating a (top secret) host of onchain records rather than trusting a single source.
Priority scoring
It finds the holdings column on its own and ranks each wallet by holdings × follower reach, so outreach starts with the people who move the most.
Exports that fit the next step
A full CSV sorted by priority, or a plain-text file shaped for a bulk Twitter List import.

How it works

  1. Upload a CSV with a wallet or address column. Value and balance columns are detected automatically, so no mapping step.
  2. Each address is resolved against several social graphs at once, with optional onchain record lookups (slower, but the most accurate path).
  3. Results cache in Postgres for 24 hours, so re-running or growing a list costs nothing the second time.
  4. Filter down to Twitter-only accounts or to holders above 1,000 Farcaster followers, then export.
