Walkthrough

A new Soroban smart contract example project for weighted-threshold-policy is added under examples/multisig-smart-account/. The project includes Cargo configuration, a contract module implementing the Policy trait, and a library entry point configured for no_std compilation.

Changes

Cohort / File(s)	Summary
Project Configuration examples/multisig-smart-account/weighted-threshold-policy/Cargo.toml	Defines the new example crate with dependencies on soroban-sdk and stellar-accounts, configured as an unpublished library compiled as a cdylib.
Smart Contract Implementation examples/multisig-smart-account/weighted-threshold-policy/src/contract.rs, src/lib.rs	Implements WeightedThresholdPolicyContract with Policy trait implementation; provides contract methods for managing threshold and signer weights (get_threshold, get_signer_weights, set_threshold, set_signer_weight).

Poem

🐰 A weighted policy takes form,
With thresholds set just right,
Smart accounts now have the charm,
Of signatures balanced tight!
