FAQ

Flit is a cross-chain bridge for Chains, L2s and rollups secured by SparkleX's Services. It is optimized for capital efficiency with liquidity pool, a competitive relayer landscape, and a no-slippage fee model.

Designed by the engineers who built SparkleX, Flit was the result of approaching bridging not only as a technical concern but as a financial engineering concern.

How long does it take to receive my funds?

Flit' bridging speed depends on the number of relayers and the speed at which they are relaying.

The typical transfer occurs within 1-4 minutes. This occurs when relayers have sufficient assets on the destination chain. If relayers have insufficient assets on the destination chain, but have excess assets on Mainnet, they will be sent to destination to complete the relay. This process can take 10-30 minutes for the user transaction to complete. If there are not enough assets on the destination chain plus Mainnet, the transfer will be slow relayed which can take 2-4 hours. All of this will be communicated upfront for users in the 'time to destination' field. If you have not received your funds within the quoted 'time to destination' value, please reach out to Dev Support in the Flit Discord.

What is a liquidity provider?

A liquidity provider (LP) is someone that provides liquidity to one of the Flit pools. This liquidity is used to reimburse relayers after the relay has been verified by the Services.

In return for providing this liquidity, LPs receive fees.

Provided there is enough liquidity in the pool, a liquidity provider can withdraw their position at any time.

What does a relayer do?

A relayer enables users to make instantaneous transfers between chains by providing the capital upfront. In return for providing this service, they are able to collect fees from the users.

Who is Flit Labs and what role do they play as a foundation?

The Flit Labs foundation supports a team working on Flit, full-time.
