+The following bridges offer cross-chain swaps (token bridging including swap) to or from Flow EVM. 
+
+## Liquidity Pool Based Cross-chain Swaps 
+
+### Stargate
+
+[Stargate](https://stargate.finance) employs unified liquidity pools shared across multiple chains to enable native asset transfers and cross-chain swaps 
+without wrapped tokens. It is built on LayerZero's cross-chain messaging protocol.
+
+### Celer
+
+[Celer](https://cbridge.celer.network) is a hybrid liquidity network bridge that combines multiple bridging models and is based on the Celer 
+Inter-Chain Messaging Framework.
+
+## Intent Based Cross-chain Swaps
+
+Intent based bridges do not depend on pre-funded liquidity pools which can improve user experience, transaction speed and capital efficiency.
+
+### Relay
+
+[Relay.link](https://relay.link/bridge/base) allows users to specify desired cross-chain swap outcomes for orders.
+
+### DeBridge
+
+[DeBridge](https://app.debridge.finance/) achieves efficient cross-chain swaps with minimal slippage in a decentralized environment 
+through a peer-to-peer transaction mechanism.

 Below are common questions regarding stablecoins, liquidity, and bridging on Flow. Click on each question to expand and view the answer.
 
+## Bridging and Gas
+
+<Details summary="Does Flow use ETH for gas?">
+No, Flow uses $FLOW as the gas token. [WETH](./defi-contracts#stablecoins--wrapped-assets) is supported on Flow EVM when [bridging](../bridges.md) from another chain. $WFLOW is used as an ERC20 in DeFi apps and not used for gas.
+</Details>
+
+<Details summary="How do I pay for gas when bridging into Flow?">
+When using Flow EVM for the first time, your EOA will automatically be credited 0.05 FLOW to cover gas costs when bridging into Flow. 
+If further top-ups are required you can use [Gas.zip](https://www.gas.zip/). See [Fees](../../evm/fees) for information on gas pricing. 
+
+Flow Wallet users do not pay for gas since the wallet subsidizes all transaction fees.
