FAQ

Why is it called "Most"?

"Most" means "bridge" in Polish. So, technically, we're calling it "Bridge Bridge"! We liked the simplicity and directness of the name.

What happens if my order is not fulfilled?

If the order isn’t fulfilled, the funds stay locked in the Escrow contract and can be reclaimed after 1 day when the order expires. Your funds are safe and can only be claimed by a Market Maker who proves they've fulfilled the order, or by you if the order expires without being fulfilled.

What chains does Most Bridge currently support?

Currently, Most Bridge supports transfers from Optimism Sepolia (source chain) to Ethereum Sepolia (destination chain). We're working on expanding to more chains in the future.

Is Most Bridge decentralized?

Most Bridge is not decentralized. Currently, Most Bridge operates on an SMM model, where one trusted entity handles all transactions. In the future, we may transition to an MMM model, where multiple entities compete to fulfill orders, potentially leading to lower fees and increased decentralization. You can read more about the differences here: SSM 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 prove an order and withdraw the funds in one call?

No, Most Bridge deliberately separates the proof submission and withdrawal for safety purposes. This prevents leaving the contract in an inconsistent state in the case of an error occurring during the execution of a call.

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 escape hatch mechanism.

What are Storage Proofs and why are they important?

Storage Proofs are a solution developed by Herodotus, 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?

While we currently only support ETH, we plan to add support for popular ERC-20 tokens in future updates. Stay tuned for announcements!
