sygma-solidity
Sygma uses Solidity smart contracts to enable transfers to and from EVM compatible chains. These contracts consist of a core bridge contract (Bridge.sol) and a set of handler contracts (ERC20Handler.sol, ERC721Handler.sol, PermissionedGenericHandler.sol, PermissionlessGenericHandler.sol). The bridge contract is responsible for initiating and executing proposed transfers. The handlers are used by the bridge contract to interact with other existing contracts.
Deployments
To deploy contracts run truffle migrate --network NETWORK_NAME --file <path_to_env_config>.
For more details on specific flags that can be used and format of environemnt configuration check out migrations documentation page.
To add another network do the following:
- update
truffle-config.jswith the desired configuration - add the required params to config file for the desired environment (local,dev,testnet,mainnet)
- create a deploy script in
migrationsdirectory

Requires nodejs and npm.
