Band Protocol has completed a planned migration of its push-based pricing 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 smooth the path to full mainnet deployments.
Band’s integration with Sonic started as an early, experimental implementation on Blaze that allowed both teams to validate data transfer mechanisms, tighten aggregation logic, and support early builders in testing Sonic’s infrastructure. Now that the Sonic Testnet is available, Band says it has transferred its official contract to a new address on the network; builders who used the Blaze feed are asked to update their credentials so that their dApps continue to receive reliable pricing updates.
The practical details that every developer needs are simple. The Blaze testnet contract (0x8c064bCf7C0DA3B3b090BAbFE8f3323534D84d68) will be replaced by the Sonic Testnet contract (0x7ccbbEa6183a5201954942e6ff6Ca30340Bd4b9A). Both feeds will run in parallel for now, but Band has warned that the Blaze feed will be retired within about a week of 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 paves the way to Mainnet readiness
Why this matters goes beyond a simple address change. Sonic’s testnet is designed to mirror the mainnet more closely than Blaze did, which should reduce surprises when teams bring their contracts and systems to production. Band’s push-based oracle model, where validated price updates are actively pushed up the chain, remains its key benefit: lower latency, less network congestion, and more immediate price information for DeFi primitives that rely 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 room to add more assets as demand grows.
Under the hood, the integration has not changed. BandChain’s validators pull prices from multiple trusted sources, aggregate and verify the results, and then pass 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 such as swaps, credit rates, or cross-chain routing decisions. This flow, source request, validator aggregation, secure relays, and on-chain reading ensure feeds remain reliable while minimizing counterparty risk for consuming protocols.
For teams building on Sonic, this migration is a practical opportunity to sync test deployments with the network’s evolving architecture. Sonic advertises stunning performance, 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. Band frames this move as part of a close, ongoing collaboration designed to smooth the transition to the mainnet and expand the range of resources that can support the oracle.
Band thanked the first builders who tested the Blaze integration and provided feedback that helped improve the migration. Developers needing to transition can find Band’s standard reference contracts and documentation in the team’s links, and the recommended immediate action is simply to point existing integrations to the new Sonic Testnet contract at 0x7ccbbEa6183a5201954942e6ff6Ca30340Bd4b9A.
As Sonic continues to mature and Band expands its oracle coverage, the two projects say they will prioritize a smooth mainnet transition and continue to innovate in secure, low-latency data delivery for DeFi, GameFi, and emerging AI-driven on-chain services. Builders migrating quickly will benefit from working in a test environment that closely matches the conditions their applications will face when Sonic’s mainnet upgrades are rolled out.
