# Wallet Unlink

> Revert from self-custody back to managed wallet.

Restores the managed wallet mode. Users can switch back and forth freely between managed and self-custody.

Rate limited: 10 attempts per hour per API key.

Revert from self-custody back to managed wallet.

## Overview

Restores the user's managed wallet from the previous state. Users can switch back and forth freely between managed and self-custody.

## What Happens

1. `mk_ai_agent.wallet_address` is cleared (set to `NULL`)
2. **All wallet credential rows for the user are physically deleted** from
   `mk_ai_agent_wallet_credential`. This is intentional: the table has a
   unique index on `api_key`, and a soft-deleted row would block the same
   key from being re-registered against a different
   `(wallet_address, signature_type)` pair (e.g. migrating from an EOA
   to its Polymarket Deposit Wallet).
3. The user can re-link a wallet at any time via the challenge flow.

<Warning>
  Unlink is **destructive**. The CLOB API key / secret / passphrase that
  were stored for the user are removed from Aion's database and cannot be
  recovered through Aion. They can still be re-derived from the user's
  private key via Polymarket's auth endpoint.
</Warning>

<Tip>
  In most cases you do **not** need to call `/wallet/unlink` before
  re-registering. `POST /wallet/credentials` automatically reclaims the
  `api_key` slot when you register the same key against a different
  `(walletAddress, signatureType)` pair — for example, when switching
  from the bare EOA (`signatureType=0`) to the user's Polymarket Deposit
  Wallet (`signatureType=3`) after detecting it via the profile API.
</Tip>

## Rate Limiting

* **10 attempts per hour** per API key (IP-based)

## Re-linking

After unlinking, you can link the same or a different wallet by going through the challenge flow again:

1. `GET /wallet/link/challenge?address=0x...`
2. `POST /wallet/link` with the signed challenge
