);About Sonic
Connect your dApp, bot, or protocol to Sonic Mainnet with BoltRPC. Speed-sensitive workloads like trading bots and yield automation need an RPC provider that keeps up with Sonic’s 1-second blocks, and predictable request-unit pricing ensures your infrastructure costs stay predictable as your usage scales.

Sonic is the high-performance successor to Fantom Opera, rebuilt from the ground up with a new EVM execution engine targeting 10,000 transactions per second. It is DeFi-native, with native yield products and a fast finality model that makes it attractive to trading bots and yield optimizers. The Fantom DeFi ecosystem, including its established DEXes and lending protocols, migrated to Sonic. These are not experimental deployments but production protocols with established user bases that require reliable RPC access. Sonic’s speed-oriented design means that your RPC provider’s response time becomes a more meaningful variable in your application’s performance than it is on slower chains.
Yield automation and auto-compounding strategies
Sonic’s 1-second blocks and low fees make it well suited for yield automation protocols that need to trigger rebalancing, harvest and compounding operations at high frequency. Yield optimizers running on Sonic call eth_call to check APY conditions across lending and liquidity pools before each execution, then submit transactions when thresholds are met. At 1-second block times, a bot checking conditions every block runs 86,400 check cycles per day, a workload that requires reliable infrastructure and predictable request-unit pricing to operate economically.
Trading bots and on-chain arbitrage Sonic’s migrated Fantom DeFi ecosystem includes established DEXes with real liquidity. Arbitrage bots running between Sonic’s AMMs poll price feeds and liquidity depths continuously. At 1-second blocks, every block is a potential execution window. WebSocket subscriptions to new block events let bots react to price changes without polling overhead, keeping them competitive in a fast-block environment.
Price feed and oracle consumers
Protocols that consume price feeds on Sonic, whether from Chainlink oracles or on-chain TWAP sources, query feed contracts frequently to detect price deviations before making lending or liquidation decisions. These queries are read-only eth_call requests running continuously in the background of DeFi protocol operations. Predictable request-unit pricing ensures these background monitoring calls do not become a significant line item as the protocol scales.
Why BoltRPC
Sonic is built for fast finality and EVM compatibility, designed to handle high-throughput DeFi activity. When a chain produces blocks every second, your RPC endpoint becomes the remaining variable in your application's performance stack. Trading bots and yield automation scripts running on Sonic need an endpoint that keeps up with block production without introducing unnecessary delays.
Sonic's fast blocks mean trading bots and yield optimizers poll frequently. At 1-second blocks, a bot polling every block makes 86,400 requests per day from block number checks alone, before any contract calls. Published per-method request-unit pricing means this polling pattern does not compound into billing surprises.
Sonic is the upgraded successor to Fantom Opera. The Fantom DeFi ecosystem has migrated to Sonic. These are established protocols with production RPC requirements, not experimental deployments.
Any Ethereum code works on Sonic with a single endpoint change.
At Sonic's block speed, polling is inefficient. WebSocket subscriptions deliver new block notifications as they happen, without the overhead of polling every second.
