What is AstaVerse?

AstaVerse is a fully decentralized auction marketplace built on the Base Sepolia blockchain, enabling users to buy and sell digital and physical assets through transparent, smart contract-powered auctions.

Our Mission

To create a trustless, censorship-resistant auction platform where buyers and sellers can transact directly without intermediaries, backed by blockchain technology and smart contract escrow protection.

What Makes AstaVerse Different?

100% Decentralized

No central authority controls your auctions. All transactions are governed by immutable smart contracts on the blockchain.

Built-in Escrow Protection

Funds are held securely in smart contracts until delivery is confirmed, protecting both buyers and sellers from fraud.

NFT Certificates

Image auction winners receive an NFT certificate proving ownership, minted automatically on-chain.

Encrypted Communication

Built-in chat system with file attachment support lets buyers and sellers communicate securely throughout the transaction.

Dual Currency Support

Pay with ETH (Ethereum) or TBASE tokens, giving you flexibility in how you transact.

Fair Dispute Resolution

Independent admin review process ensures disputes are resolved fairly based on evidence and blockchain records.
