mcswap-sdk

Javascript SDK for the McSwap Protocol

McSwap is a Trustless Smart Escrow Protocol on the Solana Blockchain that enables app developers to build their own Marketplaces and OTC services for digital assets. Direct onchain revenue sharing is built-in and allows developers to define usage fees for when they or their application's users create or execute McSwap Escrows through their apps and tools.
