Contract Suite

DALLA Token (PSP22)

Complete fungible token implementing the PSP22 standard (Polkadot's ERC-20). Features transfer, approve, transferFrom, minting, burning, and allowance management. 12 decimal places, 100M max supply, 21M initial supply.

BeliNFT (PSP34)

Full-featured NFT contract implementing PSP34 (Polkadot's ERC-721). Supports mint, transfer, burn, metadata URIs, collection management, enumeration, and approval system. Use cases include digital art, land title NFTs, and identity documents.

Simple DAO

Lightweight governance contract with proposal creation, DALLA token-weighted voting, NFT-based membership verification, configurable voting periods, and proposal execution after quorum. Demonstrates cross-contract integration.

Faucet

Testnet token distribution contract with configurable drip amount (default 1,000 DALLA), cooldown period (100 blocks ≈ 10 minutes), owner refill, claim tracking, and usage statistics.

Hello BelizeChain

Introductory tutorial contract demonstrating basic ink! patterns — message storage, global counter, per-account visit tracking, events (MessageUpdated, CounterIncremented, VisitRecorded), and error handling.

pallet-contracts Integration
