A cross-chain bridge is a DeFi instrument that lets you move crypto assets from one network to another.
Let's say you bought $ETH on a centralized exchange like Bybit and took it to Arbitrum and placed it in a liquid staking or re-staking.
At some point, you spot a new opportunity on the Starknet blockchain.
🫱 It makes you wonder: how can I transfer my $ETH from Arbitrum to Starknet?
That's where cross-chain bridges come in.
You put your $ETH in Arbitrum, but you get it in Starknet.
There are two bridges that will cover 95% of all the necessary routes between blockchains.
1. Stargate
2. Orbiter Finance
That's all you need to know. It's really not that complicated. If you want to work with DeFi, it's a good idea to get to grips with bridges ✔️
