# Revoke a signer key

`POST /v1/auth/revoke-signer`

## Request

- Base URL: `https://api.testnet.rise.trade`
- URL: `https://api.testnet.rise.trade/v1/auth/revoke-signer`
- Auth: none required
- TypeScript: <https://skmtc.dev/rise/apis/risex-rest-api/docs/v1/auth/revoke-signer/post.ts> (a function with typed inputs; its response is checked against the schema)

Revoke a previously registered signer key. Requires **account EIP-712 signature**:

**Account signs `RevokeSigner`:**
```
RevokeSigner(address account,address signer,uint48 nonceAnchor,uint8 nonceBitmap)
```
Struct hash: `keccak256(abi.encode(TYPEHASH, account, signer, nonceAnchor, nonceBitmap))`

The type string is hashed literally, so it must be copied verbatim — a single added space yields a different typehash and the signature will not recover.

## Request body

- ApiRevokeSignerRequest
  - `account` string: Account address in hex format (0x...)
  - `signer` string: Signer address to revoke
  - `nonce_anchor` string: Bitmap nonce anchor (uint48) from GetNonceState
  - `nonce_bitmap_index` integer: Bitmap index within the nonce anchor epoch (0-207)
  - `account_signature` string: EIP712 signature from account (65 bytes hex)

## Response `200`

A successful response.

- ApiRevokeSignerResponse
  - `transaction_hash` string: Transaction hash of the signer revocation
  - `success` boolean: Whether the signer revocation succeeded
  - `status` integer: Session key status after revocation
  - `block_number` string, uint64: Block number of the revocation transaction

## Other responses

- `default`: An unexpected error response.
