Contracts

A decentralized exchange (DEX) to support STREET, the world’s first dedicated meme emission token, built on Stacks blockchain. The DEX enables swaps between WELSH Corgi Coin (WELSH) and STREET Token (STREET), liquidity provisioning, and a dedicated emission and distribution system for liquidity providers.

Architecture

The contracts form an integrated DeFi ecosystem where:

• Users provide WELSH / STREET liquidity and receive CREDIT LP tokens
• Trading fees and STREET emissions accumulate in the distribution contract
• LP token holders can claim proportional rewards at any time
