Axelar was founded with a mission to take the risk out of moving funds and messages between blockchains.

Axelar developers + @openzeppelin have created a standard for institutions that demand the highest level of security + liveness: multiple, redundant verification paths.

In March 2022, Ronin’s bridge was hacked and $620M lost through a single point of failure.

Cross-chain bridges still put your funds at risk.

OpenBridge fixes this with multi-bridge confirmation.

𝐓𝐡𝐞 𝐩𝐫𝐨𝐛𝐥𝐞𝐦 :

Today’s bridges act like isolated silos, one provider and one point of failure.

They're either unreliable due to downtime or exploitable through compromised keys

That’s a security risk and a UX hurdle.

OpenBridge is an open-source framework that lets developers send messages or assets across multiple blockchains using more than one bridge at the same time, instead of depending on just one.

Built on ERC‑7786, OpenBridge routes one message through multiple bridges using a configurable x-of-y confirmation model.

Your trade only lands once the threshold is metz no single bridge can block it.

𝐎𝐩𝐞𝐧𝐁𝐫𝐢𝐝𝐠𝐞’𝐬 𝐀𝐫𝐜𝐡𝐢𝐭𝐞𝐜𝐭𝐮𝐫𝐞:

OpenBridge uses a gateway that connects to multiple ERC‑7786 adapters like @axelar or Wormhole.

You set a threshold, for example, 2 of 3 bridges must confirm a message. An outbox tracks all bridge responses, and once the required confirmations are in, it runs executeMessage once on the destination chain.

This makes sure the message is only executed once, only when the right number of trusted bridges confirm it, giving your app better security, reliability, and flexibility across chains.

𝐊𝐞𝐲 𝐟𝐞𝐚𝐭𝐮𝐫𝐞𝐬:

⪼ Multi-confirmation security: 2‑of‑3, 3‑of‑5—you choose

⪼ High availability: if one bridge stalls, the others fulfill

⪼ Open standard & modular: You can plug in any bridge that follows the ERC‑7786 rules.

𝐀𝐱𝐞𝐥𝐚𝐫’𝐬 𝐑𝐨𝐥𝐞 𝐢𝐧 𝐎𝐩𝐞𝐧𝐁𝐫𝐢𝐝𝐠𝐞:

Axelar acts as one of the bridge adapters you can plug into your OpenBridge setup.

It connects directly to the gateway contract, alongside other bridges like Wormhole. You don’t need to change your app’s logic, just drop in the Axelar adapter and it works.

This gives you more flexibility and control without extra complexity.

𝐖𝐡𝐚𝐭 𝐎𝐩𝐞𝐧𝐁𝐫𝐢𝐝𝐠𝐞 𝐌𝐞𝐚𝐧𝐬 𝐟𝐨𝐫 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐞𝐫𝐬 𝐚𝐧𝐝 𝐔𝐬𝐞𝐫𝐬:

𝐅𝐨𝐫 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐞𝐫𝐬: OpenBridge lets you combine multiple bridges with simple rules, boosting security, uptime, and flexibility without changing your code.

𝐅𝐨𝐫 𝐔𝐬𝐞𝐫𝐬: It means safer, smoother cross-chain transactions that don’t fail if one bridge goes down.

In short, better multichain apps with less hassle and more trust.

𝐌𝐲 𝐨𝐧𝐞 𝐜𝐞𝐧𝐭 :

OpenBridge solves the single-bridge risk by using ERC‑7786 to confirm messages across multiple bridges.

This means better security, higher uptime, and freedom to choose or switch providers.

Built around a gateway array, configurable confirmation thresholds, and modular adapters, it simplifies complex multibridge logic into a secure, flexible system.

Deploy once, adapt easily, and trust in numbers, not just one bridge.
