Runnable sample apps and starter kits across Quicknode-supported chains, including Cosmos. Clone one and ship.
"Relay routes cross-chain intents across dozens of networks, so every new chain we add has to be rock-solid from the first block. Quicknode's HyperEVM support gave us the performance and uptime we need to quote and settle swaps in real time, without babysitting infrastructure."Julien Genestoux, VP of Engineering @ Uneven Labs (Relay)
