Solidity

3.1 Solidity

DEX Raiden v1 is implemented in Vyper, a Python-like smart contract language.

DEX Raiden v1.1 is implemented in the more widely-used Solidity, since it requires some capabilities that were not yet available in Vyper (such as the ability to interpret the return values of non-standard ERC-20 and BEP-20 tokens, as well as access to new opcodes such as chainid via inline assembly) at the time it was being developed.
