Band Protocol has completed a planned migration of its push-based price oracle from the Blaze testnet to the newly launched Sonic Testnet, the teams announced today. The move is intended to give developers building on Sonic a more stable, mainnet-like environment for integrating live price feeds and to smooth the path toward full mainnet deployments.
Band’s integration with Sonic began as an early, experimental deployment on Blaze that let both teams validate data relay mechanics, tighten up aggregation logic, and support early builders testing on Sonic’s infrastructure. With the Sonic Testnet now available, Band says it has switched its official contract to a new address on the network; builders who were using the Blaze feed are asked to update their references so their dApps continue to receive reliable price updates.
The practical detail every developer needs is straightforward. The Blaze testnet contract (0x8c064bCf7C0DA3B3b090BAbFE8f3323534D84d68) will be replaced by the Sonic Testnet contract (0x7ccbbEa6183a5201954942e6ff6Ca30340Bd4b9A). Both feeds are running in parallel for now, but Band has warned that the Blaze feed will be deprecated in roughly one week from the announcement, giving teams a short window to migrate. Updating the contract address is the only change required; integration patterns and the Band Price Feed interface remain the same.
Oracle Migration Clears Path to Mainnet Readiness
Why this matters goes beyond a simple address swap. Sonic’s testnet is designed to mirror the mainnet more closely than Blaze did, which should reduce surprises when teams promote their contracts and systems to production. Band’s push-based oracle model, where validated price updates are actively pushed into the chain, remains the core advantage: lower latency, less network congestion, and more immediate price information for DeFi primitives that depend on timely data. Price feeds for major tokens, including DAI, ETH, FTM, USDC, USDT and WBTC, will continue to be available on the Sonic Testnet, with scope to add more assets as demand grows.
Under the hood, the integration hasn’t changed. BandChain’s validators pull prices from multiple reliable sources, aggregate and verify the results, and then relay the aggregated price data to the on-chain reference contract deployed on Sonic. Sonic-based dApps then read those symbol-specific references to power functions like swaps, lending rates, or cross-chain routing decisions. This flow, source request, validator aggregation, secure relay, and on-chain read keep feeds trustworthy while minimizing counterparty risk for consuming protocols.
For teams building on Sonic, this migration is a practical chance to sync test deployments with the network’s evolving architecture. Sonic advertises blistering performance, up to 400,000 transactions per second and sub-second finality, so running tests in an environment that actually reflects those conditions is invaluable for performance-sensitive DeFi projects. Band frames the move as part of a close, ongoing partnership designed to make the transition to mainnet smoother and to expand the range of assets its oracle can support.
Band thanked the early builders who tested the Blaze integration and provided feedback that helped polish the migration. Developers who need to switch over can find Band’s Standard Reference Contracts and documentation in the links provided by the team, and the recommended immediate action is simply to point existing integrations to the new Sonic Testnet contract at 0x7ccbbEa6183a5201954942e6ff6Ca30340Bd4b9A.
While Sonic continues to mature and Band expands its oracle coverage, the two projects say they will prioritize a smooth mainnet transition and continue innovating around low-latency, secure data delivery for DeFi, GameFi, and emerging AI-driven on-chain services. Builders who migrate quickly will benefit from operating in a test environment that closely approximates the conditions their applications will face when Sonic’s mainnet upgrades roll out.
