# User Guide 4 - BSC Bridge

Bridging ERC-20 FOUR from Ethereum to Binance Smart Chain BEP-20 FOUR using OmniBridge and xDai Chain

When sending ERC-20 FOUR to Binance Smart Chain, the cross-blockchain bridge is needed. The Bridge enables the cross-chain token bridging in both directions. The smart contract locks the ERC-20 FOUR sent from the Ethereum, while the equivalent amount of FOUR BEP-20 is minted on BSC. When the BEP-20 FOUR needs to be bridged back to ERC-20 FOUR, the smart contract puts in a BEP-20 FOUR burn request to the Bridge, and the ERC-20 FOUR are released from the reserves. This process ensures that the total and circulating token supply don’t change.

💡 Follow the link (opens new window) to the detailed online manual.

# User Guide 5 - SPL Bridge

Ethereum ERC-20 FOUR to Solana SPL FOUR token Bridge Manual

The Solana Wormhole bridge enables ERC-20 FOUR to bridge to SPL FOUR available on the Solana blockchain. The Wormhole bridge uses decentralized cross-chain oracles (i.e. guardians) operated by a set of node operators that include top Solana validators and other ecosystem stakeholders whose incentives are strongly aligned with Solana and Serum (Solana.com, May 2021).

💡 Follow the link (opens new window) to the detailed online manual.

# User Guide 6 - PoS Bridge

Ethereum ERC-20 FOUR to Polygon FOUR token Bridge Manual

The Polygon bridge enables ERC-20 FOUR to bridge to Polygon FOUR available on the Polygon blockchain. As FOUR token Multiverse is expanding, it is important to know how to use it. The first step is always the bridge. FOUR tokens have been integrated into the official Ethereum — Polygon cross-chain bridge, so ERC-20 FOUR token holders can now easily migrate between two universes.
