HeliSwap

HeliSwap core and periphery contracts are forks of Uniswap V2 core and periphery repositories. The contracts are tailored to deployment on Hedera Hashgraph and thus HeliSwap supports both HTS and native to the Smart Contract Service ERC20 deployed tokens.

HeliSwap contracts are non-upgradeable and thus immutable. For detailed information of how the contracts work, you can go to Uniswap Docs.

Changes from Uniswap V2

• After Pair creation, in the initialisation phase, the newly created Pair associates itself through HIP-206 to the 2 pair tokens.
• Additional metadata is emitted in events to compensate for the lack of free view functions.
