v1.0.0

CHANGELOG

The major changes in this stable release compared to the beta release are:

• Tokens can be transferred directly via the ITS contract instead of TokenManagers, i.e provide the ERC20 approval (not needed for mint/burn tokens) to the ITS contract instead of the TokenManager.
• Separate TokenManager implementations have been consolidated into a TokenHandler contract. This doesn't affect the API.
• interchainTransfer now takes a gasValue param. This allows it to be used within a multicall (for e.g. transfer tokens to multiple chains in one tx).
• InterchainTransfer event has a new dataHash field. This is set to keccak256(data) if a destination contract is being called with the transfer, and bytes32(0) otherwise. InterchainTransferWithData event type was removed as a result.
• InterchainTokenExecutable.executeWithInterchainToken now takes commandId as well to allow apps to track individual messages. Similar change for the express executable.
• Distributable has been renamed to Minter for clarity. You can call transferMintership to transfer mint rights to a token.
• Removed support for deploy + transfer to remote chains in InterchainTokenFactory to reduce complexity. InterchainTokenFactory.deployInterchainToken will now mint the initial supply directly to the sender/deployer address. There is no need to transfer tokens from the factory to the sender anymore.
• Renamed BaseInterchainToken to InterchainTokenStandard, and removed the coupling with an ERC20 implementation. Custom interchain tokens can now inherit InterchainTokenStandard directly to benefit from interchain transfer support.
• Switch to using a minimal proxy for InterchainToken deployments to reduce gas usage significantly and support auto-proxy verification on explorers.
• Passing bytes4(uint32(1)) as the metadata version will pay for an express call on the gas service. This is relevant for an express relayer.
• Misc bug fixes, test coverage, and improvements.
