# Supply

Users can easily supply a supported asset to Replete protocol from any supported chain. This enables the user to earn yield on the asset provided from any chain the market is connected to.

Providing liquidity allows user to participate further in the protocol: either to borrow, withdraw or repay.

## Supply architecture

In order for user to be able to earn across all chains, Replete utilizes a supply architecture where the protocol logic, liquidity and accounting is hosted on one chain. To chain abstract the supply process, Replete utilizes a combination of messaging, interoperable token standards (such as OFT's) and bridges to maintain unified liquidity on a host chain.&#x20;

From the host chain, the connected blockchains are served with the various [features the protocol has to offer](/intro/about-replete/why-replete.md). Each transaction to connected chains follow a similar logic as the supply architecture under.

It is important for users to understand that since the <mark style="color:blue;">host chain for Replete is Arbitrum</mark>, assets supplied to Replete are transferred to the Arbitrum network. Similarly, the receipt of supplied liquidity (rToken) is at present solely available on Arbitrum.

Therefore it is important for users to make sure they control the wallet address on Arbitrum before interacting with Replete.

Note that Arbitrum is the host chain for Replete. Make sure you control the wallet address on Arbitrum before interacting with the protocol.
{% endhint %}

A benefit of this approach is that it allows Replete to scale to numerous blockchains while keeping the state of the protocol atomically correct without exposing the protocol to synchronicity risk that can occur when deploying to multiple chains.
