# Proxy (/docs/guides/evm/precompiles/proxy)

| Property            | Value                                        |
| ------------------- | -------------------------------------------- |
| Rust implementation | `ProxyPrecompile`                            |
| Solidity interface  | `IProxy`                                     |

| Status              | Deployed                                     |

## Functions [#functions]

| Function                                            | Mutability |
| --------------------------------------------------- | ---------- |
| `createPureProxy(uint8,uint32,uint16)`              | nonpayable |
| `proxyCall(bytes32,uint8[],uint8[])`                | nonpayable |
| `killPureProxy(bytes32,uint8,uint16,uint32,uint32)` | nonpayable |
| `addProxy(bytes32,uint8,uint32)`                    | nonpayable |
| `removeProxy(bytes32,uint8,uint32)`                 | nonpayable |
| `removeProxies()`                                   | nonpayable |
| `pokeDeposit()`                                     | nonpayable |
| `getProxies(bytes32)`                               | `view`     |
| `getProxyDeposit(bytes32)`                          | `view`     |
| `getAnnouncements(bytes32)`                         | `view`     |
| `getLastCallResult(bytes32)`                        | `view`     |
| `isRealPaysFee(bytes32,bytes32)`                    | `view`     |

`getLastCallResult` returns stable success/error metadata. Module errors expose
the pallet index and four error bytes. Error kinds are `1` Other, `2`
CannotLookup, `3` BadOrigin, `4` Module, `5` ConsumerRemaining, `6`
NoProviders, `7` TooManyConsumers, `8` Token, `9` Arithmetic, `10`
Transactional, `11` Exhausted, `12` Corruption, `13` Unavailable, `14`
RootNotAllowed, and `15` Trie. This avoids returning SCALE-encoded runtime
data.

## Added operations [#added-operations]

| Function             | Source extrinsic            |
| -------------------- | --------------------------- |
| `announce`           | `Proxy.announce`            |
| `removeAnnouncement` | `Proxy.remove_announcement` |
| `rejectAnnouncement` | `Proxy.reject_announcement` |
| `setRealPaysFee`     | `Proxy.set_real_pays_fee`   |

## Proposed operation [#proposed-operation]

| Function         | Source extrinsic        |
| ---------------- | ----------------------- |
| `proxyAnnounced` | `Proxy.proxy_announced` |

`proxyAnnounced` must use the same versioned, stable EVM call description as
other typed proxy execution. A new interface must not introduce another
dependency on SCALE-encoded `RuntimeCall`.

No selector is reserved for `proxyAnnounced`.
