Let me walk through how APRO Oracle integrates with non-EVM blockchains—specifically Bitcoin via Discreet Log Contracts (DLC), Solana, and TON. This part of APRO’s design is notable because it bridges very different blockchain architectures without sacrificing reliability or efficiency.
At its core, APRO operates as a decentralized oracle network that combines off-chain data processing with on-chain verification. This model is essential for non-EVM chains, where execution environments differ significantly from Ethereum. Bitcoin, for example, lacks native smart contracts, so APRO uses a specialized oracle signature service built for DLCs. DLCs enable conditional Bitcoin payments based on external events. APRO’s nodes generate oracle signatures off-chain, which are then used to resolve DLC outcomes. Nodes aggregate data from multiple sources, validate it through consensus, and sign results using multi-signature schemes. This prevents single points of failure while remaining compatible with Bitcoin’s UTXO model.
On Solana, which operates on the Solana Virtual Machine (SVM), APRO adapts to high throughput and parallel execution. Solana requires low-latency data delivery, so APRO relies on a hybrid node architecture that separates off-chain computation from on-chain verification. Data is delivered through compatible services using its Off-Chain Messaging Protocol (OCMP). A two-layer structure supports this flow: the primary layer focuses on fast data transmission among nodes, while a secondary dispute layer—referenced through frameworks like EigenLayer—adds verification and resolution. This setup supports Solana DeFi applications by enabling real-time feeds with minimal latency and cost, while cross-validating sources to reduce manipulation risk.
For TON, APRO focuses on real-time data delivery suited to TON’s asynchronous and sharded design. Oracles on TON must be flexible, so APRO integrates its staking and slashing framework to enforce node accountability. Nodes post collateral, face penalties for inaccurate data, and remain open to community challenges. Integration points deliver price feeds and event data for TON-native assets and DeFi protocols. Both push and pull data modes are used: push updates for automated threshold-based changes, and pull requests for high-frequency use cases. This keeps TON smart contracts synchronized with external data while aligning with its cell-based architecture.
Across all three networks, APRO relies on a multi-network communication framework. It emphasizes resilient node coordination, time-weighted average pricing (TVWAP) for accuracy, and consistent oracle behavior across EVM and non-EVM chains. Heavy computation stays off-chain, while trust and verification remain on-chain.
For developers, this means access to price feeds, event triggers, and structured data without dealing with the underlying complexity. APRO abstracts the differences between chains while respecting their constraints, delivering a unified oracle layer focused on reliability and practical deployment.
