ChainPort Private Bridge

Full control and security for your token – manage supported chains, path, amounts, and own the keys

How ChainPort Private Bridge Works

ChainPort Private Bridge combines the best features from ChainPort with extra security features and an upgraded key management solution. It makes use of 3-of-5 wallets to access the cold storage that holds up to 98% of the tokens and empowers its security.

ChainPort’s team holds 2 keys; you or your team hold 2 keys, while a 3rd party trustee, aka a reputable law firm, holds the 5th key. By splitting the keys into 5 parts, no one party can move the funds without a majority.

This protects funds in case of any sort of extreme scenario where recovery is needed. It is an emergency withdrawal method for your tokens on the bridge under certain extreme circumstances. In short, it removes the need for trust and is a last-resort withdrawal method for your tokens on the bridge.

Your token will still enjoy the cross-chain interoperability, our support, API, fast porting cross chains, and all our other great features.
