Band Protocol x Sonic: Migrating to the Sonic Testnet
We are delighted to share that Band has successfully migrated from the Blaze testnet to the Sonic Testnet.
TL;DR
- Band has officially migrated its price feed oracle from the Blaze testnet to Sonic Testnet, ensuring continuity and improved performance for dApps on the network.
- The Band Price Oracle is now live on the new Sonic Testnet at contract address: 0x7ccbbEa6183a5201954942e6ff6Ca30340Bd4b9A
- All developers previously building with Band Oracle on the Blaze testnet are encouraged to update their integrations to point to the new contract address.
- Band Price Feed on the Blaze testnet will be deprecated. Both feeds are running in parallel now, but builders on Blaze have approximately 1 week to migrate to the new Sonic Testnet contract before the Blaze feed is shut down.
- Price feeds for DAI, ETH, S, USDC, USDT, and WBTC continue to be supported, with the capacity to expand as demand grows.
- Band remains committed to supporting Sonic's ecosystem and beyond.
Introduction
We are delighted to share that Band has successfully migrated from the Blaze testnet to the Sonic Testnet.
Since our initial integration as the first push-based oracle on the Sonic testnet and the Mainnet, Band and Sonic have been working hand in hand to provide developers with the most reliable and efficient oracle infrastructure possible. As Sonic continues to evolve its testnet environment, we are committed to keeping pace, ensuring that Band Oracle remains a dependable foundation for every dApp building on the network.
This migration reflects both teams' dedication to a stable, high-performance ecosystem of Sonic.
What's Changing: Blaze Testnet → Sonic Testnet
The Blaze testnet served as an important proving ground for Band's push-based oracle on Sonic. It allowed us to validate our integration, fine-tune data relay mechanisms, test ideas, and support early builders in the ecosystem. Now that the Sonic Testnet has been introduced, it is time to move forward.
The key change developers need to know:
- Previous contract address (Blaze testnet): 0x8c064bCf7C0DA3B3b090BAbFE8f3323534D84d68
- New contract address (Sonic Testnet): 0x7ccbbEa6183a5201954942e6ff6Ca30340Bd4b9A
All other integration patterns remain the same. If you have already built with Band Price Feed on the Blaze testnet, updating your contract reference to the new address is all that is needed to get back up and running on Sonic Testnet.
While both the Blaze testnet and Sonic Testnet feeds are currently running in parallel, Band Price Feed on the Blaze testnet will be deprecated in approximately 1 week after this announcement.
Why This Migration Matters
The Sonic Testnet represents a more mature and stable environment that closely mirrors what the Sonic mainnet will offer. By migrating now, developers gain several key advantages:
- Better Alignment with Mainnet: The testnet environment is architecturally evolving as Sonic's mainnet upgrades, meaning integrations built and tested here will require minimal to zero changes in the current mainnet iteration.
- Continued Push-Based Oracle Performance: Band's push-based oracle continues to deliver real-time data updates with reduced latency and lower network congestion, all the benefits you've come to rely on, now running on a stronger foundation.
- Uninterrupted Price Feed Support: Price feeds for DAI, ETH, FTM, USDC, USDT, and WBTC remain fully supported, and the testnet environment is ready to accommodate additional assets as ecosystem demand grows.
How Band Oracle Works on the Sonic Testnet: High-Level Overview
The integration process remains consistent with what was established during the Blaze testnet phase:
1. Request Data: BandChain requests the price of DAI, ETH, WBTC, USDC, USDT, and S from multiple reliable data sources via validators.
2. Aggregate Data: Band’s validators aggregate and verify data from the sources, ensuring comprehensive and accurate information is gathered.
3. Relay Data: The aggregated data is securely transmitted through BandChain to the Standard Preference Contract deployed on Sonic.
4. Read Symbol: Sonic’s dApps read the data symbols from Band Standard Reference Contracts on Sonic, retrieving the information they need for their operation.
5. Send Price Data: The accurate and verified price data is delivered to the dApps on Sonic, enabling them to utilize real-time information for their functions.
Update Your Integration Now
If you are an existing builder who was using Band Oracle on the Blaze testnet, here is what you need to do to migrate.
Simply update your contract reference to the Sonic Testnet address to: 0x7ccbbEa6183a5201954942e6ff6Ca30340Bd4b9A
Tools and Resources for Developers
Wrapping Up and Upcoming Milestones
This migration marks another important step in the Band and Sonic partnership. Looking ahead:
- Mainnet Readiness: With the Sonic Testnet now live and Band Oracle fully migrated, both teams are well-positioned for a smooth transition to mainnet. dApps building on Sonic today will receive our exclusive priority support.
- Expanded Asset Support: As the ecosystem grows, Band is ready to extend price feed coverage beyond the current set of supported assets.
- Ongoing Innovation: We remain committed to evolving our oracle infrastructure in step with Sonic's development, ensuring developers always have access to the most reliable, efficient, and secure data feeds.
We thank all early builders who tested and provided feedback during the Blaze testnet phase. Your contributions made this migration possible. We look forward to continuing this journey together on Sonic and beyond.
