novatip-contracts

Soroban smart contracts for Novatip — tap-to-tip any creator in seconds, with tips split across collaborators on-chain and settled in USDC on Stellar.

This repository holds the on-chain core. The backend (novatip-backend), web app (novatip-web), shared SDK (novatip-sdk), and docs (novatip-docs) live in separate repositories under the same organization.

Contracts

Contract	Status	Purpose
tip-splitter	✅ v0.1.0	Receives a tip and splits it across recipients by basis points
supporter-badge	planned	Non-transferable badge minted to supporters

See docs/CONTRACT.md for the full tip-splitter interface.

Quick start

# One-time: the Stellar CLI builds contracts for this target
rustup target add wasm32v1-none

# Build all contracts to wasm
make build

# Run the test suite
make test

Without the target installed, make build fails with can't find crate for core — the CLI moved from wasm32-unknown-unknown to wasm32v1-none. make test runs natively and works either way.

Tech

• Rust + Soroban SDK
• Stellar CLI for build & deploy
• Tips settle in USDC (Stellar Asset Contract)

Network Deployments

Network	Contract ID	Status
Testnet	CCY2WPXROVUMPYAK3YJHZ57I35JKAUM5GDJKLUF5Y72KGENBQNSYAJIW	live
Mainnet	coming soon	pending audit

The testnet deployment settles in the testnet USDC SAC below, and carries a @demo jar splitting 70/30 between two accounts for anyone wanting to try the read methods without deploying their own.

USDC Stellar Asset Contract addresses:
