REX (Resource EXchange) transitioned from the old “staking to CPU/NET” [resource model](https://help.eossupport.io/en/articles/5790704-the-resource-system-on-eos) to the new [EOS PowerUp Model](https://eosauthority.com/powerup). Staking to CPU/NET does not provide any function.

## **Short-term solution (if transaction is stuck):**

**Power up your account using** the [EOS PowerUp](https://eospowerup.io/free) services sponsored by [boid.com](https://boid.com/) (the social supercomputer) and [EOS Network Foundation](https://eosnetwork.com/). You can power up your account for one time for free in 24 hours. It's free for you, but remember that the EOS Community is donating EOS to this contract and is paying for your transactions. Donations can be made to the EOS Account “eospowerupio” to support the service.

More information can be found here: [How to use the power up service](https://help.eossupport.io/en/articles/5756424-how-to-use-the-power-up-service)

## **Long-term solution (beginners):**

We recommend that you **install the newest version of the [Anchor Wallet](https://greymass.com/en/anchor/)**. Anchor wallet offers around 5-10 free transactions per day (sponsored by Greymass). After downloading, set up a new Anchor Account, then import your private key to access your EOS account.

**Anchor offers automated resource management, which will also take care of the resources**. The wallet automatically calculates each transaction (RAM, CPU, and NET) as soon you used up your free transactions. This only works if the dApp also supports this new method.

Note: If you don't have EOS in your account, you will not be able to pay transaction fees. Anchor Wallet will display an “overdrawn balance” error in this case.

## **Long-term solution (power users):**

1) **Use free transactions** from [Anchor](https://greymass.com/en/anchor/) or from [bloks.io](http://bloks.io/) (not working with Anchor or with the mobile version), [eosauthority.com](http://eosauthority.com/), [newdex.io](http://newdex.io/), etc., in combination with [Wombat](https://getwombat.io/)

2.1) **Rent resources (CPU/Net) for 24 hours**

<https://bloks.io/wallet/powerup>

<https://eosauthority.com/power?network=eos>

2.2) **Deposit EOS to pre-purchase the Auto-PowerUp service**

Accounts in your watch list receive automatic resources dynamically based on live usage: <https://eospowerup.io/auto>

## **Other problems?**

### **Lost Transaction**

#### Sometimes the transaction does not find its way into a block. Just try it again.
