Adds support for listing expiration tracking by adding the expires_at: u64 field to the Listing struct. This is the foundational change for auto-expiration and auto-delisting functionality.
Adds foundational infrastructure for auction system: - New storage keys: AUCTION_CTR_KEY, AUCTION_PREFIX - Helper functions: next_auction_id, auction_key - Integrates with existing stellai_lib Auction struct - Prepares contract for full auction implementation
Implements core auction bidding functionality: - create_auction: Creates new auctions with configurable parameters - place_bid: Validates and records bids with minimum increment checks - record_bid: Updates auction state with new bid information - Auto-refunds outbid bidders to ensure proper fund management
Adds two critical marketplace systems: 1. Offer system: make_offer, accept_offer, reject_offer with expiration 2. Dispute system: open_dispute, resolve_dispute with admin-only arbitration - Storage keys: OFFER_CTR_KEY, DISPUTE_CTR_KEY, OFFER_PREFIX, DISPUTE_PREFIX - Helper functions: next_offer_id, next_dispute_id, offer_key, dispute_key
Completes marketplace feature set with: - Transaction history tracking: record_transaction, get_user_transactions - Platform fee configuration: set_platform_fee, configurable 2.5% default - Royalty distribution enforcement in all sale workflows - Listing auto-expiration: cleanup_expired_listings - Transaction analytics functions (placeholder implementation) - All event publishing for frontend integration - Fixes all ownership and compilation errors, contract builds successfully
Add the missing expires_at field (set to u64::MAX) to the first three test listings in the marketplace contract's test suite. This resolves compilation errors caused by the updated Listing struct definition.
Implement the main cross-chain bridge contract with initialize, add_validator, initiate_transfer, and complete_transfer functions. Includes core bridge functionality for locking/burning tokens on source chain and minting/unlocking on destination chain.
Add core type definitions (ChainID, BridgeTransfer, Validator, RateLimitConfig), error handling (BridgeError enum), and storage key helpers for the cross-chain bridge contract.
Add Token trait for token interactions (burn, mint, transfer_from, transfer) and comprehensive test suite covering bridge initialization, validator management, transfer initiation, and transfer completion.
Add Cargo.toml with dependencies (soroban-sdk, stellaiverse-lib) and README.md documenting bridge features, architecture, usage, and security considerations.
Update core library errors and types to support cross-chain bridge functionality, including adding any new error variants and type definitions required for the bridge implementation.
