Band Protocol has completed its planned migration of push-based pricing oracles from the Blaze testnet to the newly launched Sonic Testnet, the team announced today. This move is intended to provide developers building on top of Sonic with a more stable mainnet-like environment to integrate live price feeds, smoothing the path to full mainnet deployment.
Band and Sonic’s integration began as an early experimental deployment on Blaze, allowing both teams to validate how data relay works, harden the aggregation logic, and support initial builder testing on Sonic’s infrastructure. With Sonic Testnet now available, the Band says it has switched its official contract to a new address on the network. Builders who were using Blaze feeds are asked to update their references to ensure their dApps continue to receive reliable price updates.
The practical details that every developer needs are simple. The Blaze testnet contract (0x8c064bCf7C0DA3B3b090BAbFE8f3323534D84d68) is replaced by the Sonic testnet contract (0x7ccbbEa6183a5201954942e6ff6Ca30340Bd4b9A). For now, both feeds are running in parallel, but Band cautioned that teams have less time to transition, as the Blaze feed will be retired within about a week of announcement. The only change required is updating the contract address. The integration pattern and band price feed interface remain the same.
Ready for mainnet with migration to Oracle
Why this is important goes beyond simple address exchange. Sonic’s testnet is designed to more closely mirror the mainnet than Blaze, reducing surprises when teams move contracts and systems into production. Band’s push-based oracle model remains a core advantage in that verified price updates are proactively pushed onto the chain. This means lower latency, less network congestion, and more instant price information for DeFi primitives that rely on timely data. Price feeds for major tokens such as DAI, ETH, FTM, USDC, USDT, and WBTC remain available on Sonic Testnet, with room to add assets as demand increases.
Internally, the integration remains unchanged. BandChain’s validators retrieve prices from multiple trusted sources, aggregate and validate the results, and relay the aggregated price data to on-chain reference contracts deployed on Sonic. Sonic-based dApps then read symbol-specific references to power functions such as swaps, lending rates, and cross-chain routing decisions. This flow, source requests, validator aggregation, secure relays, and on-chain reads maintain the authenticity of the feed while minimizing risk for counterparties using the protocol.
For teams building on Sonic, this transition is a practical opportunity to synchronize test deployments with the evolving architecture of the network. Sonic touts impressive performance of up to 400,000 transactions per second and sub-second finality, so running tests in an environment that actually reflects these conditions is invaluable for performance-sensitive DeFi projects. The band plans this transition as part of a deep, ongoing partnership aimed at making the transition to mainnet smoother and expanding the range of assets that Oracle can support.
Band thanked early builders for testing the Blaze integration and providing feedback that helped improve the migration. Developers who need to make the switch can find Band’s standard reference agreement and documentation at links provided by the team. The recommended immediate action is to point the existing integration to the new Sonic Testnet contract (0x7ccbbEa6183a5201954942e6ff6Ca30340Bd4b9A).
As Sonic continues to mature and Band expands its oracle reach, the two projects say they will prioritize smooth mainnet transitions and continue to innovate around low-latency, secure data delivery for DeFi, GameFi, and emerging AI-driven on-chain services. Builders migrating quickly will benefit from operating in a test environment that closely approximates the conditions their applications will face when Sonic’s mainnet upgrades are deployed.
