Calling APIs

Note : Before the assets are transferred across the chain, The Rangers Protocol team would need to review these assets. If the transferred assets are FT, the quantity approved in the contract address must be larger than or equal to the quantity of cross-chain FTs.

The cross-chain smart contract of Rangers Protocol can support cross-chain operations under Rangers Bridge. Additionally, any person or organization can invoke an interface to perform cross-chain operations as long as it meets the cross-chain specification:
