Getting Started
Looking to build a dApp on Sonr? Following this documentation and our academy you can learn how and become part of the rich ecosystem of EVM builders on Cosmos. Whether you are building new use cases on Sonr or porting an existing dApp from another chain, you’ll want to check out the sections onConfiguration

If true, query the ABCI app on connecting to a new peer so the app can decide if we should keep the connection or not.
TCP or UNIX socket address for the RPC server to listen on.

Activate unsafe RPC commands like /dial_seeds and /unsafe_flush_mempool.
Maximum number of simultaneous connections (including WebSocket). Does not include gRPC connections. See grpc_max_open_connections.
Maximum number of unique clientIDs that can /subscribe. If you’re using /broadcast_tx_commit, set to the estimated maximum number of broadcast_tx_commit calls per block.
Maximum number of unique queries a given client can /subscribe to. If you’re using GRPC (or Local RPC client) and /broadcast_tx_commit, set to the estimated maximum number of broadcast_tx_commit calls per block.
Experimental parameter to specify the maximum number of events a node will buffer, per subscription, before returning an error and closing the subscription. Must be set to at least 100, but higher values will accommodate higher event throughput rates (and will use more memory).
Experimental parameter to specify the maximum number of RPC responses that can be buffered per WebSocket client. If clients cannot read from the WebSocket endpoint fast enough, they will be disconnected, so increasing this parameter may reduce the chances of them being disconnected (but will cause the node to use more memory).
Enabling this experimental parameter will cause the WebSocket connection to be closed instead if it cannot read fast enough, allowing for greater predictability in subscription behavior.
How long to wait for a tx to be committed during /broadcast_tx_commit. WARNING: Using a value larger than 10s will result in increasing the global HTTP write timeout, which applies to all connections and endpoints.

Maximum size of request header, in bytes.
The path to a file containing certificate that is used to create the HTTPS server. Might be either absolute path or path related to CometBFT’s config directory. If the certificate is signed by a certificate authority, the certFile should be the concatenation of the server’s certificate, any intermediates, and the CA’s certificate.
