The evolution of decentralized oracles takes a bold leap forward with the launch of Band Oracle v3 Testnet Phase 2. This pivotal upgrade represents months of rigorous engineering, community collaboration, and architectural innovation — all aimed at building a faster, more secure, and truly interoperable data oracle for the entire blockchain ecosystem.
At its core, Band Oracle v3 is designed to empower developers across chains with reliable, real-time data. With Phase 2, we’re not just improving performance — we’re redefining how oracles operate in a multi-chain world.

A New Era of Oracle Performance
Band Oracle v3 Testnet Phase 2 delivers groundbreaking improvements over both Band v2 and the initial v3 testnet release. These aren’t incremental tweaks — they’re foundational upgrades that push the boundaries of speed, capacity, and decentralization.
Key performance milestones include:
- 3x faster block times: Feed update intervals have been reduced from 6 seconds to just 1 second, enabling near real-time data delivery.
- 10x increase in symbol capacity: The network can now support significantly more price feeds, unlocking opportunities for complex DeFi protocols and data-rich applications.
- 10x higher daily throughput: More data, more frequently, without compromising reliability.
- Decentralized Threshold Signing (TSS): All cryptographic operations remain trustless and distributed, ensuring security isn’t sacrificed for speed.
These enhancements make Band Oracle v3 a powerful backbone for next-generation use cases — from high-frequency decentralized finance (DeFi) platforms to on-chain gaming economies and real-world asset tokenization.
For developers, this means lower latency, higher accuracy, and greater scalability. For end users, it translates into smoother experiences, tighter price feeds, and more resilient smart contracts.
Real-Time Telemetry: Building Smarter Validator Operations
One of the standout features of Phase 2 is the integration of real-time telemetry into two critical system components: Grogu and Cylinder. This shift transforms validator operations from reactive to proactive — even predictive.
Grogu: Monitoring Price Signal Health
Grogu now provides granular insights into how price signals are submitted and processed across the network. Validators can track:
- Signal delivery times and success rates
- Individual validator responsiveness
- Reliability across different feed types (e.g., crypto, forex, commodities)
This visibility allows node operators to identify bottlenecks before they impact performance.
Cylinder: Securing TSS with Precision
Cylinder manages the decentralized signing process via Threshold Signature Scheme (TSS). With new telemetry capabilities, validators gain real-time visibility into:
- Signing latency and success metrics
- Instant detection of signature aggregation failures
- Automated alert triggers for repeated signing failures
This level of observability strengthens network resilience by enabling rapid diagnostics and mitigation — essential for maintaining uptime in mission-critical environments.
Together, Grogu and Cylinder lay the foundation for predictive maintenance, reducing downtime and increasing overall network efficiency.

Interoperability First: Expanding the Data Tunnel
True decentralization means being chain-agnostic. Band Oracle v3 Testnet Phase 2 advances this vision through major upgrades to the Data Tunnel module, enabling seamless data delivery across heterogeneous blockchain environments.
IBC-Hook: Streamlined Integration for IBC Chains
IBC-Hook allows smart contracts on IBC-enabled chains to receive price data directly over existing token transfer channels. No separate oracle-specific channel required. This simplifies integration and reduces overhead for chains like Cosmos SDK-based networks.
Router Protocol: Bridging EVMs and Beyond
Router enables secure cross-chain messaging to non-IBC ecosystems such as Ethereum Virtual Machine (EVM) chains — with upcoming support for Solana. Already tested successfully in staging environments, this integration will soon go live for production use.
Developers can now build applications that pull trusted data from Band into EVM-compatible environments without complex middleware or trust assumptions.
Axelar Network: Trusted Data Relay
Our collaboration with Axelar enhances secure data transmission between BandChain and non-IBC chains using robust verification mechanisms. This partnership ensures that off-chain data remains tamper-proof and cryptographically verifiable — no matter the destination chain.
These integrations collectively move us closer to a unified data layer for Web3, where any smart contract on any chain can access reliable, decentralized data.
Under-the-Hood Enhancements for Stability & Usability
Beyond headline features, Band Oracle v3 Phase 2 includes several under-the-hood refinements that improve developer experience and system robustness:
- Cylinder standalone commands: Operators can now execute diagnostic and management tasks without interrupting service.
- Block time-based signal submission: Replacing system time with block time ensures consistency across nodes, reducing timing discrepancies.
- Module-level telemetry: BeginBlock and EndBlock durations are now measured for TSS, Oracle, Feeds, and Tunnel modules, giving validators fine-grained performance monitoring.
- Automatic TSS group selection: Simplifies validator operations by automating group activation processes.
- Yoda gas optimization: Our transaction orchestrator now dynamically adjusts gas settings to prevent transaction failures due to insufficient fees.
These improvements reflect Band’s commitment to operational excellence — ensuring smooth deployment, monitoring, and maintenance throughout the network lifecycle.
What’s Next on the Roadmap
Band Oracle v3 is rapidly approaching maturity. Here’s what lies ahead:
- Comprehensive review and feedback collection from Testnet Phase 2
- Ongoing validation of all Data Tunnel integrations
- Backend optimizations for enhanced efficiency
- Improved validator tooling and observability dashboards
- Seamless migration pathways for ecosystem participants
- And most importantly: Mainnet Launch — Q3 2025
This timeline underscores our focus on stability, security, and broad adoption before going live.
