}The Cosmos Transaction Simulator supports simulation of transactions across Cosmos SDK-based networks including Osmosis and Neutron, providing the same detailed analysis available for Solana, instruction parsing, balance changes, state predictions, and risk assessment.
For Cosmos-based addresses, use the Address Risk Score endpoint to check risk levels before transacting. Supported Cosmos networks include
osmosis-1, cosmoshub-4, dydx-mainnet-1, neutron-1, celestia, and more.
Contact us for early access or updates on availability.Authorizations
