# Maximum Available Liquidity

{% hint style="warning" %}
If you're going to initiate a cross-chain request, please make sure there's enough buffer liquidity on the target chain since there will always be a time gap between reading the stats and executing the request.
{% endhint %}

The major concept is that we can get the rough available liquidity by getting the balance of the `YBridgeVault` contract If the deposit token is native token. If it's ERC20-like token, we get the balance of the `YBridgeVault` contract from the vault token's ERC20 contract.

However, the balance we get directly from the contract is just a rough number since some of the balance might belong to the YBridge worker.

If you need a more accurate way to access the Maximum Available Liquidity, please use the following API ([get-pool-liquidity](https://docs.xy.finance/single-bridge-integration/ybridge-api/get-pool-liquidity "mention")) to obtain liquidity information.
