Types of Allbridge Core transfers

Cross-chain swaps

Once the transaction is initiated, assets are swapped on the Source chain to the virtual value transfer tokens. These tokens transfer the information via the selected messaging protocol. When the message arrives, it triggers the contract on the Destination chain, and the virtual tokens are swapped into the desired asset.

Extra gas

Allbridge Core offers an option to receive additional gas tokens on the Destination chain by charging an extra fee in Source chain gas. This makes Allbridge Core convenient for entering the new chain or topping the newly created wallet.

Messaging protocols

Allbridge Core is built on top of multiple messaging protocols, offering wider blockchain coverage:

• Wormhole messaging powers transfers between Solana, Ethereum, Polygon, and BNB Chain.

• Allbridge messaging is used for cross-chain swaps between Tron and other supported chains.

• CCTP messaging is available for USDC-to-USDC swaps.

Non-upgradable smart contracts

• Non-upgradability of contracts contributes to the bridge’s security, removing the malicious intrusions into the transfers as a potential attack vector.
