# Zipwire's Master Attester Wallet Address and Public Key

## Overview

**This is the official, authoritative source for Zipwire's master attester wallet address and public key.** These details are used to issue attestations on the Base blockchain and should be referenced from this page rather than repeated elsewhere in the documentation.

Zipwire issues attestations, such as "IsAHuman," to Ethereum wallets using a master attester wallet address and public key. This page provides these details for verification purposes, ensuring users and platforms can confirm the authenticity of Zipwire-issued attestations on the Base blockchain.

## Master Attester Details

Below are Zipwire's official master attester wallet address and public key, used to issue attestations:

* **Ethereum Address**: `0x2651ef3d909828eff9a9bdd6454eb5f98b045e76`
* **Public Key**: `0x04f585f43d96b93c921d4a9d2307f36a4fe1faea39a3c737a1e228295c3bcbef4813f69674b467de30e67888f1e63c13c0e12e2decd5fd623f08f7ef7959cd4b64`

These details are critical for verifying attestations, as described in [Verifying Attested Wallets](/fundamentals/security/wallet-verification-guide/verifying-attested-wallets.md).

## Verifying Authenticity

To ensure these details haven't been compromised (e.g., by a hacked documentation site), cross-reference them with trusted sources:

* **Zipwire's GitHub**: Check the official repository for the latest public key and address: <https://github.com/zipwireapp/zipwireapp/blob/master/PUBLICKEYS.md>.
* **EAS Scan (Base Blockchain)**: Review the attestation history for the master address (`0x2651ef3d909828eff9a9bdd6454eb5f98b045e76`) to confirm its activity: <https://base.easscan.org/>.

A mismatch between this page and GitHub or EAS Scan may indicate a security issue. Report discrepancies to Zipwire immediately.

## Usage Guidelines

When referencing these details in other documentation or applications:

1. **Link to this page** rather than copying the address and public key
2. **Cross-reference with GitHub** for additional verification
3. **Check EAS Scan** to verify the address is actively issuing attestations
4. **Report any discrepancies** immediately

## Why It Matters

Zipwire's master attester details enable users and platforms to verify the legitimacy of attestations, such as those used in sleeper wallets or identity checks. By confirming the attester's address and public key, you ensure trust in the verification process, protecting against fraudulent or compromised wallets.
