# Manage Token Delegations

> Learn how to approve, revoke, and manage token delegations using the Enclave MPC API.

Portal's Enclave MPC API supports token delegation operations across EVM and Solana chains. This guide covers building delegation transactions via the Client API and signing them with the Enclave MPC API.

## Overview

The delegation endpoints allow you to:

* **Approve** other addresses to spend tokens on behalf of your wallet
* **Revoke** existing delegations to remove spending permissions
* **Check status** of active delegations and balances
* **Transfer tokens** as a delegate from another address

## Prerequisites

Before using delegation operations, ensure you have:

* A properly initialized Portal client (see [Create a client](./create-a-client))
* An active wallet with tokens on the target network (see [Create a wallet](./create-a-wallet))
* Understanding of [token delegations concepts](/resources/delegations)

<Warning>
  Delegations apply to ERC-20 tokens (EVM) and SPL Tokens (Solana) only. Native assets like ETH, MON, and SOL cannot be delegated — they have no on-chain `approve` / `transferFrom` (or SPL delegate) semantics. Calls using a native asset identifier will be rejected. See [Delegations](/resources/delegations#what-are-token-delegations) for the protocol-level reason and workarounds.
</Warning>

## Approving Delegations

Approving a delegation is a two-step process: build the unsigned transaction with the Client API, then sign and submit it with the Enclave MPC API.

### Step 1: Build the Approval Transaction

Use `POST /api/v3/clients/me/chains/{chain}/assets/{token}/approvals` to build an unsigned approval transaction.

For complete API documentation, see the [Client API reference](../../client/reference#approve-a-delegation).

## Checking Delegation Status

Use `GET /api/v3/clients/me/chains/:chain/assets/:token/delegations` to check active delegations and token balances. This is a read-only call that does not require signing.

## Revoking Delegations

Revoking follows the same two-step pattern: build the revocation transaction, then sign and submit it.

### Step 1: Build the Revocation Transaction

Use `POST /api/v3/clients/me/chains/:chain/assets/:token/revocations` to build an unsigned revocation transaction.

For complete API documentation, see the [Client API reference](../../client/reference#revoke-a-delegation).

<Tabs>
  <Tab title="EVM">
    ```bash theme={null}
    curl --request POST \
      --url 'https://api.portalhq.io/api/v3/clients/me/chains/eip155:11155111/assets/USDC/revocations' \
      --header 'Authorization: Bearer [clientApiKey|clientSessionToken]' \
      --header 'Content-Type: application/json' \
      --data '{
      "delegateAddress": "0xc74c4f7e330a62e0023f50b2b7b0491878fb4aa4"
    }'
    ```
  </Tab>

  <Tab title="Solana">
    ```bash theme={null}
    curl --request POST \
      --url 'https://api.portalhq.io/api/v3/clients/me/chains/solana:EtWTRABZaYq6iMfeYKouRu166VU2xqa1/assets/USDC/revocations' \
      --header 'Authorization: Bearer [clientApiKey|clientSessionToken]' \
      --header 'Content-Type: application/json' \
      --data '{
      "delegateAddress": "7KAJGeyLUdLXv9p7rFYpYUnX5Jac6CYMTuJSQr7FZzz1"
    }'
    ```
  </Tab>
</Tabs>

The response structure matches the approval response, returning `transactions` (EVM) or `encodedTransactions` (Solana).

### Step 2: Sign and Submit the Transaction

Sign and submit the revocation transaction using the same Enclave MPC signing flow shown in the [approval step](#step-2-sign-and-submit-the-transaction).

For complete API documentation, see the [Enclave MPC API reference](../../enclave-mpc/reference#sign-a-transaction-or-message-by-chain).

<Warning>
  Always revoke unused delegations after completing operations to minimize security risks.
</Warning>

***

## Transferring as a Delegate

Once an owner has approved your address as a delegate, you can transfer tokens from their wallet to a destination address.

### Step 1: Build the Transfer Transaction

Use `POST /api/v3/clients/me/chains/:chain/assets/:token/delegations/transfers` to build an unsigned transfer-as-delegate transaction.

For complete API documentation, see the [Client API reference](../../client/reference#transfer-as-a-delegate).

<Tabs>
  <Tab title="EVM">
    ```bash theme={null}
    curl --request POST \

      --header 'Authorization: Bearer [clientApiKey|clientSessionToken]' \

### Step 2: Sign and Submit the Transaction

Sign and submit the transfer transaction using the same Enclave MPC signing flow shown in the [approval step](#step-2-sign-and-submit-the-transaction).

For complete API documentation, see the [Enclave MPC API reference](../../enclave-mpc/reference#sign-a-transaction-or-message-by-chain).

<Note>
  **Delegation Roles**: `fromAddress` is the token owner who approved the delegation. Your wallet (the delegate) signs the transaction to transfer tokens from the owner to the `toAddress` recipient.
</Note>

***

## Supported Networks

Delegations work on all Portal-supported EVM and Solana chains:

* **EVM**: Ethereum, Polygon, Base, Arbitrum, Optimism, Monad, and all other EVM-compatible chains
* **Solana**: Solana Mainnet and Devnet

For a complete list, see [Blockchain Support](/resources/blockchain-support).
