Escrow Vault Protocol

Trustless Escrow Infrastructure on Solana

Version 1.0 | December 2025

Abstract

Escrow Vault is a decentralized escrow protocol built on Solana that enables trustless, transparent, and automated custody and release of digital assets. By leveraging Solana's high-performance blockchain and Anchor smart contract framework, Escrow Vault provides a secure infrastructure for peer-to-peer transactions, eliminating the need for trusted intermediaries while maintaining flexibility through programmable release conditions.

1. Introduction

Traditional escrow services rely on centralized intermediaries to hold and release funds, introducing counterparty risk, delays, and unnecessary costs. Escrow Vault eliminates these inefficiencies by implementing escrow logic directly in Solana smart contracts.

The protocol supports multiple asset types including native SOL, SPL tokens, and NFTs, with flexible release conditions ranging from mutual approval to time-based locks and milestone-triggered releases.

2. Problem Statement

Current escrow solutions face several critical challenges:

  • •Centralization Risk: Funds held by third parties can be frozen, seized, or misappropriated
  • •High Fees: Traditional escrow services charge 2-5% of transaction value
  • •Slow Settlement: Multi-day clearing periods for fund release
  • •Limited Transparency: Opaque processes and unclear fund custody
  • •Geographic Restrictions: Services unavailable in many jurisdictions

3. Escrow Vault Architecture

Escrow Vault's architecture consists of three core components:

Program Layer

Solana programs written in Rust using the Anchor framework. Handles escrow initialization, state management, and fund transfers.

Account Layer

Program Derived Addresses (PDAs) that custody escrowed assets. Each escrow has a unique PDA vault deterministically generated from escrow parameters.

Client Layer

TypeScript SDK and web interface for creating and managing escrows. Abstracts blockchain complexity while maintaining non-custodial control.

4. Smart Contract Design

The Escrow Vault smart contract implements four core instructions:

initialize_escrow
Creates escrow account and transfers assets to PDA vault
approve_escrow
Marks escrow as approved by required parties
release_escrow
Validates conditions and transfers assets to receiver
cancel_escrow
Returns assets to sender and closes account

5. Security Model

Escrow Vault implements multiple security layers:

  • • PDA-based custody ensures only program can transfer funds
  • • Signer validation prevents unauthorized state changes
  • • Condition checks enforce release requirements
  • • Account validation prevents malicious account substitution
  • • Comprehensive test coverage and third-party audits

6. Dispute Resolution

For complex transactions, Escrow Vault supports optional third-party arbiters who can resolve disputes and authorize fund release or refund. Future versions will integrate with decentralized arbitration networks and DAO governance.

7. Token Utility

The Escrow Vault token provides multiple utilities within the ecosystem:

  • • Fee discounts based on holding tier
  • • Governance voting rights for protocol upgrades
  • • Arbiter staking and reward distribution
  • • Access to premium features and advanced escrow logic
