The XRPL Standard Library provides safe, type-safe access to XRPL host functions for WebAssembly smart contract development. This no_std library offers zero-cost abstractions over raw host function calls and handles memory management, error handling, and type conversions.
There is an interface available at https://ripple.github.io/xrpl-wasm-std/ui/ for local or Devnet testing.

Smart escrows run in a constrained WebAssembly environment:
- Read-only ledger access (except escrow data updates)
- Deterministic execution required
- Resource limits enforced
- No network/file system access
