Are there blockchain bridges in operation for any dApps now?

The bridges currently in operation have only been operating in their current form for a few months, so they are still in their early days in terms of adoption.

However, bridges hold a lot of promise, particularly for stablecoins. Tether (USDT) has had to continuously expand to new networks in an attempt to keep up with its growth. The company’s chief technology officer, Paolo Ardoino, has indicated an interest in the use of bridges to help this scaling effort. Syscoin is also in talks with stablecoin projects that are interested in using its bridge.

Given the relative immaturity of this nascent field, it’s inevitable that some bridge implementations are also experiencing issues. In May, a trust-minimized Bitcoin–Ethereum bridge called tBTC had to be shut down two days after launching because developers found a bug in the code that made it impossible to continue operating.

Nevertheless, it seems inevitable that with the current focus on scalability and interoperability, bridges will form an integral part of the blockchain landscape of the future.
