Base interface for validating and executing GMP contract calls.

Interface that allows to expedite GMP calls by lending assets and performing execution before it fully propagates through the Axelar network.

This contract is used to deploy your Executable to have the same address on different EVM chains. This simplifies message validation from peer Executables. You can learn more in the documentation.

Base implementation of upgradable contracts designed to be deployed with ConstAddressDeployer and to have the same Proxy address on different EVM chains.

Allows developers to create their own cross-chain gateways for ERC20 and ERC721 tokens utilizing the GMP protocol. Also it's a great example how to use AxelarExecutable with Upgradable.

Allows conversion between string and address data types

Allows conversion between string and bytes32 data types for storing strings under 31 bytes into a single storage slot
