According to TechFlow, Ethereum Rune Protocol Ethrunes announced the launch of LaunchPad + Swap trading model LaunchSwap, which integrates token issuance and transactions.

When tokens are issued, they will all be injected into the liquidity pool and a floor price will be set. When the number of tokens in the liquidity pool exceeds 50%, the transaction price is the same as the floor price. When the number of tokens in the liquidity pool is less than 50%, the product constant formula of x*y=K is activated. This model aims to provide fair launch, protect the interests of all holders, and realize transactions without authorization. At the same time, this model can be combined with NFT contracts to bring more choices to users.

It is reported that Ethrunes is a new token protocol based on ERC1155 and inspired by BRC20. It is a combination of inscriptions and smart contracts, also known as smart inscriptions.
