## Stellar Bridge contracts

Our integration with Stellar features a different validation model (in partnership with Ultra Stellar, who are acting as a second signer of transactions). This is why there is a separate set of smart contracts for networks that are connected to Stellar.   

If you are interested in integrating Stellar, you may use this [link](https://github.com/allbridge-io/allbridge-contract-docs/blob/master/allbridge-multisig-abi.json) to access Stellar Bridge ABI.
