Messaging protocols

Allbridge Core uses messaging protocols to move information between blockchains. Particularly, it is used to send information about transfers and their value to the recipient's blockchain. Allbridge Core architecture allows support for multiple messaging protocols. Currently, supported protocols are:

  • Wormhole is a decentralized protocol operated by Jump Crypto and used by their own Portal Bridge. Does not support Tron.

  • Allbridge's own messaging protocol, which is less decentralized (just 2 validators) but works with all blockchains Allbridge Core supports, including Tron.

  • Circle's Cross-Chain Transfer Protocol (or CCTP for short), a permissionless on-chain utility that can burn native USDC on the source chain, and mint native USDC on the destination chain.

Wormhole protocol is more decentralized, compared to Allbridge messaging. However, Allbridge messaging is quicker (since less time is required to reach a consensus), less expensive (smaller transactions), and it also supports Tron.

For USDC-specific transfers, Allbridge Core offers an option to use CCTP. This allows to maintain low slippage rates even at large transaction volumes because USDC is natively minted and burned through CCTP.
