Using the Light Bridge
The light bridge allows you to bridge particular assets into any direction that has been whitelisted. At the day of writing it is the fastest and most convenient way to bridge assets on Boba.
How to use LightBridge?
Head over to the Gateway
Connect your wallet
Select "Light Bridge" in the tabs
Happy bridging!
How does it work?
From a birds-eye perspective we do have 3 components:
The User interacting with the user-interface such as the Gateway DApp,
The Smart Contracts (Proxy + Implementation contract) and
The Backend
The Flow
The User deposits the funds to be bridged onto the Smart Contract.
The Smart Contract issues the
AssetReceived
event.The Backend Service distributes funds on the destination network by calling the Smart Contract.
For some networks you might receive some free gas to conduct 1-2 transactions. Please check Gas Airdrop
In-Depth Flow
Supported Routes
A Route is just a fancy name for defining what asset can be bridged to which network. So let's dive in.
<->
= bi-directional, bridging in both directions possible ->
= uni-directional, bridging only in one direction possible
Minor note: The routes and limits also apply to testnet.
BOBA
BOBA can bridged between the following networks. For your convenience, we've added the chainId in brackets.
BOBA BNB Mainnet (56288) <-> BNB Mainnet (56)
BOBA BNB Mainnet (56288) <-> BOBA ETH Mainnet (288)
ETH Mainnet (1) <-> BOBA ETH Mainnet (288)
BOBA ETH Mainnet (288) <-> BNB Mainnet (56)
Limits for bridging BOBA
Minimum Amount to be bridged: 20 BOBA
Maximum Amount to be bridged: 20 000 BOBA
Maximum Amount to be bridged per day & per route (for all users combined): 40 000 BOBA
BNB
These are the supported routes for BNB.
BOBA BNB Mainnet (56288) <-> BNB Mainnet (56)
Limits for bridging BNB
Minimum Amount to be bridged: 0.01 BNB
Maximum Amount to be bridged: 2 BNB
Maximum Amount to be bridged per day & per route (for all users combined): 6 BNB
ETH
ETH can be bridged from and to these networks.
Arbitrum One (42161) -> BOBA ETH Mainnet (288)
Optimism Mainnet (10) -> BOBA ETH Mainnet (288)
ETH Mainnet (1) <-> BOBA ETH Mainnet (288)
Limits for bridging ETH
Minimum Amount to be bridged: 0.01 ETH
Maximum Amount to be bridged: 2 ETH
Maximum Amount to be bridged per day & per route (for all users combined): 6 ETH
Gas Airdrop
If you bridge from ETH Mainnet to either BOBA ETH or BOBA BNB Mainnet you might receive some gas if you match certain conditions.
Along with the source network being ETH Mainnet you need to fulfill the following:
have less than 0.5 BOBA on Boba BNB (since BOBA is native there) or 0.0005 ETH on Boba ETH,
bridge a non-native asset. Means if you bridge BOBA from Boba Ethereum to Boba BNB you will not receive gas, since BOBA is the native asset on Boba BNB,
must not have received an airdrop in the last 24h.
How to Bridge programmatically
You can bridge any asset listed in the Supported Routes section this way.
