About Custodia

decentralized escrow platform that secures payments between buyers and sellers

Custodia is a decentralized escrow platform built on Ethereum that revolutionizes secure transactions between buyers and sellers. By leveraging blockchain technology, we eliminate intermediaries while ensuring funds are protected until all agreement terms are met. Custodia provides a transparent, tamper-proof system where transactions are recorded on-chain, giving both parties unprecedented confidence in digital commerce. Inspiration We were inspired by: The $5.5B lost annually to online payment fraud Centralized escrow services charging exorbitant fees (5-10% per transaction) The lack of transparency in traditional escrow systems Ethereum's potential to create trustless financial systems What it does Custodia is a decentralized escrow platform that: 🔐 Secures transactions between buyers and sellers using Ethereum smart contracts. 💼 Holds funds in escrow until all agreement terms are met. ⚖️ Provides neutral arbitration for dispute resolution. 🔍 Offers complete transparency with all transactions recorded on blockchain. 💸 Reduces fees by 90%+ compared to traditional escrow services. 🌐 Enables global transactions without intermediaries.
