Cross Chain Bridges

By utilizing 3-4 DAPP Network services a cross chain bridge can be established

Services used:

• vRAM - store receipt data from bridge transaction

• LiquidHarmony - oracle requests for state of finality of transactions

• LiquidScheduler - call LiquidHarmony oracles on cron like re-occuring interval

• LiquidLink - sign EOSIO and ETH (EVM) transactions with or without multi signature

The smart contract code, local environment setup, and unit tests for running an example EOSIO <> ETH fungible token bridge may be found here: https://github.com/liquidapps-io/zeus-sdk/tree/master/boxes/groups/sample/ethtokenpeg

EOSIO <> EOSIO fungible token here: https://github.com/liquidapps-io/zeus-sdk/tree/master/boxes/groups/sample/tokenpeg

EOSIO <> EVM non fungible token here: https://github.com/liquidapps-io/zeus-sdk/tree/master/boxes/groups/sample/atomictokenpeg

EOSIO <> EOSIO non fungible token here: https://github.com/liquidapps-io/zeus-sdk/tree/master/boxes/groups/sample/atomictokenpeg

Production Bridges:

Below are some bridges which are currently in production, they are both EOSIO <> ETH bridges.
