We build decentralized marketplaces for digital and physical goods. Trustless escrow, on-chain reputation, tokenized incentives, and seamless commerce experiences.
Web3 marketplaces replace centralized intermediaries with smart contracts that manage listings, payments, escrow, and dispute resolution trustlessly. Sellers reach global audiences without platform gatekeeping, buyers transact with cryptographic guarantee of payment terms, and both parties benefit from lower fees and transparent rules. Arthiq builds marketplace infrastructure that makes this vision practical.
Our Web3 marketplace development extends beyond NFT trading to encompass general commerce — freelance services, digital products, physical goods with shipping verification, and professional services with milestone-based payments. Each marketplace type has specific requirements for payment timing, delivery verification, and dispute resolution.
We have built marketplace infrastructure as part of our own products and for clients across multiple industries. This experience informs our approach — we understand the practical challenges of marketplace adoption, including the chicken-and-egg problem of building simultaneous supply and demand, and we design incentive structures that address these challenges.
Trustless escrow is the foundation of decentralized commerce. Our escrow contracts hold buyer payments until delivery conditions are met, then release funds to the seller. Release conditions can be time-based (automatic release after a period), buyer-confirmed (buyer approves delivery), oracle-verified (shipping tracking confirms delivery), or milestone-based (partial releases at defined project stages).
Our payment contracts support multiple token types — stablecoins for price stability, native tokens for protocol utility, and custom tokens for marketplace-specific economics. We implement automatic fee collection with configurable marketplace fees, creator royalties for secondary sales, and referral commissions for network growth.
For recurring services, we build subscription contracts that manage periodic payments with grace periods, cancellation policies, and automatic renewal. For large purchases, we implement installment payment contracts that release funds to sellers incrementally while protecting buyers against non-delivery.
Marketplaces depend on trust between strangers. We build on-chain reputation systems that aggregate transaction history, delivery ratings, dispute outcomes, and verification status into reputation scores that buyers and sellers can evaluate before transacting.
Our reputation systems are sybil-resistant — you cannot create a new account to escape bad reviews, and you cannot inflate your reputation through self-dealing. Reputation scores are weighted by transaction value and age, with recent transactions weighted more heavily than older ones.
For professional service marketplaces, we implement credential verification through soul-bound tokens or verifiable credentials that attest to skills, certifications, or past achievements. These credentials provide additional trust signals beyond transaction-based reputation.
Not every transaction goes smoothly. We build dispute resolution mechanisms that handle disagreements fairly without requiring centralized authority. Our dispute resolution options include mutual resolution (buyer and seller negotiate), arbitration (selected arbitrators review evidence and decide), and jury-based resolution (randomly selected community members vote on outcome).
Dispute processes include evidence submission periods, response windows, and escalation paths. Arbitrators or jurors are incentivized through stake-based selection — they deposit tokens that are slashed for dishonest rulings and rewarded for consensus-aligned decisions.
For marketplaces that need faster resolution, we implement optimistic escrow — funds are released automatically unless the buyer raises a dispute within a defined period. This speeds up the typical case (no dispute) while preserving protection for the exceptional case (legitimate dispute).
We build marketplace frontend interfaces that provide familiar e-commerce experiences with Web3 capabilities. Product browsing, search and filtering, seller profiles, order management, and chat are all standard features. Wallet integration, token payments, and escrow status tracking are layered in seamlessly.
Growth mechanics include referral programs with on-chain tracking, early adopter incentives through token airdrops, and network effects through composable listings that can be surfaced by aggregator platforms. We design tokenomics that reward marketplace activity and align stakeholder interests.
