# FAQ ### Why is it called "Most"? "Most" means "bridge" in Polish, and this bridge is proudly built in Poland. So, technically, we're calling it "Bridge Bridge"! We liked the simplicity and directness of the name, while sprinkling in some of our polish roots into the crypto ecosystem. ### What happens if my intent is not fulfilled? If the intent isn’t fulfilled, the funds stay locked in the Escrow contract and can be reclaimed after the expiry window you set when the intent was created. Your funds are safe and can only be claimed by a Market Maker who proves they've fulfilled the intent, or by you if the intent expires without being fulfilled. ### What chains does Most Bridge currently support? Currently, Most Bridge supports transfers from Optimism Sepolia and Starknet Sepolia (source chains) to Ethereum Sepolia (destination chain). We're working on rolling out broader mainnet support. ### Is Most Bridge decentralized? Most Bridge is not decentralized. Currently in v1, Most Bridge operates on an SMM model, where one trusted entity handles all intent fulfillments. In the future, we want to transition to an MMM model, where multiple entities compete to fulfill intents, potentially leading to lower fees and increased decentralization. You can read more about the differences here: [SMM vs. MMM](https://docs.most.wtf/architecture-overview/smm-vs.-mmm) ### What is a Market Maker (MM)? A market maker is an entity that facilitates the cross-chain transfer by fronting their funds to the user on the destination chain, in exchange for a fee. ### What fees do I need to pay? There are two types of fees: 1. A Market Maker fee, which you set when initiating the bridge transaction. This incentivizes Market Makers to process your transaction quickly. 2. Gas fees for the transaction on the source chain. The total amount you'll receive on the destination chain is your transfer amount minus the Market Maker fee. ### Can I cancel a bridge transaction after I've initiated it? Once a transaction is initiated and confirmed on the blockchain, it can't be cancelled. However, if the Market Maker hasn't processed it, you can reclaim your funds after 24 hours using the refund intent mechanism. ### What is HDP and why is it important? Herodotus Data Processor (HDP) is a solution developed by [Herodotus](https://x.com/HerodotusDev) that allows Most Bridge to cryptographically verify that a transaction has occurred on the destination chain without needing to directly access that chain. This enables fast and secure cross-chain transfers without relying on complex consensus mechanisms between chains. ### Will Most Bridge support other cryptocurrencies besides ETH? Yes. Most supports ETH and ERC-20 tokens. We plan to expand supported assets and networks over time.
