trix is a cerealization protocol for promise pipelining over EVM-based JSON-RPC.
Fetching hierarchical data is a common challenge in RPC-based systems. The naive solution requires H+1 client-side RPC calls, which degrades performance as your system grows in complexity. In traditional environments, this problem is commonly addressed using BFFs, eager loading, or with GraphQL. However, applying the BFF pattern at scale on Ethereum is economically infeasible, eager loading is not supported, and although GraphQL-based protocols exist to address this issue, I don't believe that application developers should have to pay for basic data access.
This whitepaper, and reference contract, demonstrate how promise pipelining can be achieved in the EVM, and how it can be used in conjunction with multicall to simultaneously join several independent models in a single request. My hope is that this contribution makes web3 development, and the client-side runtime performance, suck less. In the future, I hope supporting packages are created to provide either a GraphQL, or a JSON-API include style interface to facilitate contract interaction.
