Our verdict on Vaulta REX
6.3/10Vaulta REX suits holders of the EOS (Vaulta) token who want to earn from network resource rental, or who need CPU and NET without staking them permanently. Its strength is that income is tied to real network usage and it has run since 2022. The main caveat is that yields are variable, fees and terms are not, and it only matters inside one chain that has just been rebranded.

What is Vaulta REX?
Vaulta REX is the Resource Exchange on the EOS network, which was rebranded as Vaulta on May 14, 2025, according to a search result from a wallet provider. DefiLlama lists it under Lending on the EOS chain, with about $34.4M in TVL and a listing date of February 2022.
Its function is narrower than a typical money market. REX lets users lend and borrow CPU and NET, the resources that power transactions on the chain, and lets lenders earn system protocol income such as RAM fees, name bids, CPU/NET loans and PowerUp fees.
The official URL points to EOS Authority, a third-party explorer and wallet that lists REX as a product. That means this review rests on DefiLlama data and a thin homepage, so details like current yields and exact terms are not confirmed here.
How Vaulta REX works
REX is a resource market. Token holders deposit tokens into REX and receive a claim on the pool. Other users pay to rent CPU and NET, the network resources that let an account send transactions and run contracts, for a fixed period. Rental payments flow back to the pool.
DefiLlama also says REX captures system protocol income, including RAM fees, name bids, CPU/NET loans and PowerUp fees. Lenders therefore earn from real network activity rather than from a borrowing market with collateral and liquidations.
Because returns depend on demand for resources, yields can rise and fall. REX also typically has withdrawal timing rules, so funds may not be instantly liquid. Check current terms in the interface.

Key features
01
CPU and NET rental
Users can rent CPU and NET, the resources that let EOS accounts run transactions and contracts, without permanently staking tokens.
02
Lending for yield
Token holders lend into the exchange and earn a share of income from resource loans and other system activity.
03
Protocol income sources
DefiLlama says REX earns from RAM fees, name bids, CPU/NET loans and PowerUp fees, tying returns to network usage.
04
Native to EOS
REX runs at the system level of the EOS network, so it is not a separate third-party chain deployment.
05
Explorer and wallet access
The EOS Authority site lists REX as a product beside its wallet, explorer, voting and tools.
06
Audits listed
DefiLlama lists two audits for the project, though details are not.
Pros and cons
What we like
- Income comes from real network resource demand and system fees rather than token emissions alone.
- Native to the EOS (Vaulta) chain, with TVL of about $34.4M in DefiLlama data.
- Listed since February 2022, so it has a multi-year presence.
- DefiLlama shows two audits listed.
- Accessible via a wallet and explorer that list REX alongside voting and tools.
Watch out for
- Yield comes from resource-rental demand and protocol income, so it can change and is not guaranteed.
- Fee and rate details are not published.
- The EOS-to-Vaulta rebrand and token upgrade can confuse newcomers about which token and wallet to use.
- TVL fell 5.3% over the last seven days in the DefiLlama data, which shows it can move quickly.
- The entry point is a third-party explorer and wallet page, not a dedicated product site.
- It is useful mainly within one chain, so it does not suit users who want cross-chain DeFi.
Vaulta REX fees
The project does not publish a fee schedule for REX. DefiLlama says it earns from RAM fees, name bids, CPU/NET loans and PowerUp fees, which are network-level income sources rather than a separate platform charge.
Renting resources costs a market-driven price paid in tokens, and lenders' returns change with demand. Users should check current rates on the REX page in a compatible wallet or explorer before committing funds. Normal network transaction costs may also apply.
Is Vaulta REX safe?
DefiLlama lists two audits for the project, but public sources do not name the auditors or share results, so treat that as a signal rather than proof. REX works at the network's system-contract level, so its risk is tied to the chain itself as well as to contract design.
Using REX through a wallet means you hold your own keys. Phishing, mistaken transfers and confusion over the token upgrade are practical risks. Yields are variable and not guaranteed. The project does not report incidents, but check recent network news and never deposit more than you can lose.
6 steps
How to get started with Vaulta REX
- 1
Check that you hold the network's token and understand the EOS-to-Vaulta rebrand and the 1:1 upgrade to A tokens.
- 2
Choose a wallet or explorer that supports REX, such as the EOS Authority wallet listed publicly.
- 3
Open the REX section and review current lending rates, rental prices and any maturity or withdrawal rules.
- 4
Start with a small amount to learn how deposits, income and withdrawals behave.
- 5
If you need CPU or NET, compare renting with other ways to get resources.
- 6
Monitor returns and TVL trends periodically, and keep private keys secure.
Who Vaulta REX is for
Vaulta REX is for existing EOS or Vaulta token holders, developers who need CPU and NET for accounts and apps, and users comfortable with chain-native tools. It is a poor fit for people seeking cross-chain DeFi or fixed returns.
Vaulta REX FAQs
What is Vaulta REX?
REX stands for Resource Exchange. It is a system on the EOS network (now branded Vaulta) where users lend tokens to earn income and others rent CPU and NET resources needed to run transactions and apps.
How do you earn with REX?
DefiLlama describes REX income as coming from system protocol sources: RAM fees, name bids, CPU/NET loans and PowerUp fees. Actual returns depend on network demand and are not guaranteed.
How much is locked in Vaulta REX?
DefiLlama lists TVL at about $34.4M, down 5.3% over seven days. The figure changes constantly, so check a live source before relying on it.
Did EOS become Vaulta?
On May 14, 2025, EOS was rebranded as Vaulta, and EOS tokens were upgraded 1:1 to A tokens, according to a search result from a wallet provider. DefiLlama still lists the token as EOS, so confirm current ticker names in your wallet.
Is REX audited?
DefiLlama lists two audits for the project, but public sources do not name the auditors or findings. REX is a core part of the network's system contracts rather than a standalone app, but all smart-contract use carries risk.
What does REX cost?
The project does not give fee figures. Renting resources has a market-based cost, and lending income varies, so check the REX page in a compatible wallet or explorer for current rates.
