Announcing OpenBridge. Now, applications can secure high-value transactions using multiple crosschain protocols 🔒 🔒 OpenBridge is based on ERC-7786, a message-passing standard endorsed by the @ethereumfndn Interoperability Working Group 🧵 👇

With OpenBridge, an application can combine multiple interoperability protocols or bridges in a single transaction, requiring verification from some or all of them. This configuration, sometimes called x of y of n, can be used to enhance security for high-value transactions.

Example: A lending protocol could enable loans on @arbitrum secured by collateral deposits on Ethereum or Bitcoin blockchains—verified via 2 interop protocols and a trusted verifier set. For small transactions, it could accept verification from any of the 3. For large transactions, it could require the trusted set + 1 of the protocols to verify the collateral deposits, before issuing the loan on Arbitrum.

OpenBridge is brought to you by Axelar developer @interop_labs + blockchain security leader @OpenZeppelin - the same teams that led development of the ERC-7786 standard. It is completely open-source: no proprietary code, externally owned accounts or venture-backed middlemen.
