nesdie

This is just meant as an experimental no_std SDK which will follow similar patterns of near-sdk-rs but optimize for minimal code size and operations. This will be a worse devX than the near sdk, but can be used as an alternative to writing bare metal contracts without an SDK.

Features

  • wee_alloc (default): Configures the global allocator by default with wee_alloc
  • panic-message: Configures panic_handler to include error details, which will show up on chain. Disabled by default to optimize code size
  • oom-handler: Configures alloc_error_handler to minimize error handling in this case. This feature does not currently work with a stable toolchain

Goals for nesdie:

  • Strict no_std for wasm binaries
  • Little to no code bloat
    • No use of core::fmt
    • No serde and gate serialization protocols by feature to allow disabling
  • Minimize gas costs through less instructions
  • Similar amount of boilerplate/structure as near-sdk-rs
  • Better error handling in codegen to avoid having to panic or unwrap errors
  • Don't include local paths in built binary (from panics and asserts)
