What is the match rate for wallet-to-social lookups?

There is no single match rate, and the chain matters more than anything else. Measured across 26 collections and 72,318 holders on 2026-08-17, against our own index with no external calls: Base 46.2%, Ethereum 16.6%, Robinhood Chain 15.6%, and 30.8% across all three. Base is roughly three times Ethereum because Base is where Farcaster lives. Tools that match wallets to social accounts typically publish rates in the low single digits, so even the lowest chain here clears that by a wide margin. Farcaster matches are deterministic: the index covers the complete Farcaster protocol (every account’s verified and custody addresses, refreshed daily), so if a wallet belongs to a Farcaster user, we find it. Twitter matches are resolved through several independent routes and every match is labelled with the evidence behind it. Over 99.9% come from owner-attested routes: an X account verified on Farcaster, a handle the owner set in an onchain ENS record, or an account the owner proved by signing with the wallet and signing in to X. The remainder is correlated from identity indexes and labelled as such. Nothing is inferred from display names, bios or timing.

How much does walletlink.social cost?

walletlink.social charges for matches, not for wallets: a match is a wallet we resolve to an X or Farcaster account, and a wallet we cannot resolve costs nothing. The free tier gives 100 matches every 30 days. Credit packs are Trial at $29 for 250 matches, Campaign at $99 for 1,500 matches, Scale at $299 for 6,000 matches, Index at $899 for 25,000 matches. Every pack includes all seven chains, uncapped CSV export, API access, reverse lookup from a handle to its wallets, deep scan with onchain ENS, and X reachability on every match. All packs are one-time payments, not subscriptions, and credits last 12 months.

How is walletlink.social different from Addressable?

Unlike Addressable which requires sales calls and enterprise contracts, walletlink.social offers instant self-serve access. You can start for free immediately, with simple one-time pricing instead of monthly subscriptions. Addressable’s matched-owner counts are built with probabilistic “fingerprinting”; walletlink.social never fingerprints. Over 99.9% of Twitter matches are owner-attested (Farcaster verifications, onchain ENS records, and accounts proven by wallet signature), the rest are correlated from identity indexes and labelled as such, and every match carries the class of evidence behind it so you can set your own threshold. The index covers 4.8M wallets with complete Farcaster coverage.

Does walletlink.social support Farcaster?

Yes. Farcaster is walletlink.social’s deepest coverage. The index includes the complete Farcaster protocol: every account’s verified and custody addresses with usernames and follower counts, refreshed daily. Lookups return usernames, follower counts, and FIDs, and reverse lookup (handle → wallets) works for any Farcaster user.

How many wallets does walletlink.social cover?

The index covers 4.8 million wallets with at least one linked social identity. Farcaster coverage is complete: every account’s verified and custody addresses, refreshed daily. Over 1.15 million wallets have a linked Twitter handle, nearly all of them owner-attested: an X account verified on Farcaster, a handle the owner set in an onchain ENS record, or an account the owner proved by signing with the wallet and signing in to X.

Which blockchains does walletlink.social support?

walletlink.social supports seven EVM chains: Ethereum, Base, Robinhood Chain, Arbitrum, Polygon, Optimism and BNB Chain. You can upload a wallet list from any of them, or import every holder of an NFT collection or ERC-20 token directly from its contract address. Both import types work on every supported network.

Can walletlink.social identify AI agent wallets?

Yes, walletlink.social automatically identifies AI agent wallets from platforms like Virtuals Protocol, ElizaOS, and Olas. Agent wallets are flagged with their name, framework, and token symbol. This helps you distinguish between human users and AI agents in your wallet lists.

One answer, not an API surface.

Airstack gave you a query language. We give you the one join it was usually built to perform, as a CSV or an endpoint.

What happened to Airstack?

Airstack was a web3 development platform best known for its Farcaster APIs. On 5 March 2025 it deprecated every Farcaster-related API, so developers could no longer fetch Farcaster data from it, and its docs pointed them to another provider.

Checked on 22 August 2026: airstack.xyz now redirects to senpi.ai, an AI trading product that its founders describe as spun out of Airstack, and the Airstack app and API hosts are down. Nothing on the old endpoints accepts a request or a sign-up. If your product depended on Airstack for Farcaster identity data, that dependency needs a new home.

We check whether the X account still exists. Airstack did not.

Farcaster stores a verified X account as a name, written once, with no account number and no later check. So when somebody renames or gets suspended, nothing in the protocol notices. Every tool built on those verifications carries the same dead handles, and none of them can tell you which.

We resolve the X handles in the index against X itself, on a daily schedule. Of 448,069 checked so far: 69.6% live, 20.6% suspended, and 9.7% names nobody holds any more. Roughly a third reach no person at all.

Every match now carries that answer. The handle export leaves out the ones we checked and found dead, so a campaign is not sending into accounts that cannot receive it. A freed name matters most: somebody else may hold it now, and a message would reach a stranger.

Check any handle yourself, free and without an account.

Status	Live, refreshed daily	Deprecated 5 March 2025; site redirects to senpi.ai
Farcaster coverage	Complete protocol: every FID’s verified and custody addresses	Was full social graph APIs
Wallet → socials API	(every pack)	Offered, no longer available
Reverse lookup (handle → wallets)	(any Farcaster handle)	Offered, no longer available
Bulk CSV lookups	(no code required)

What is walletlink.social?

We turn wallet addresses into social profiles, in the browser or over a simple REST API. Our index covers 4.8M wallets with complete Farcaster protocol coverage: every account’s verified and custody addresses, usernames, and follower counts, refreshed daily. Over 99.9% of X matches are user-attested, most through an X account verified on Farcaster and the rest through onchain ENS records.

If you used Airstack for Farcaster identity resolution, the API (included with every pack) covers the same core jobs: wallet → socials, and reverse lookup from any Farcaster handle to its wallets. If you only need a one-off enrichment, skip the API entirely and upload a CSV.

Migrating from Airstack

Three steps to replace your Airstack integration:

Map your queries: wallet-to-identity and handle-to-wallets calls both have direct equivalents in our REST API
Grab an API key, included with every pack from $29, drawing the same credits as the app
Point your app at the new endpoints: responses include Farcaster usernames, FIDs, and follower counts
