This page documents the RPC interface family for IXO Protocol. It does not document application service APIs such as Impact Hub Registry, IXO Blocksync, or IXO Matrix.

​
Overview

  • Use this interface for protocol-level operations against chain nodes.
  • Prefer this when you need direct interaction with IXO Protocol modules.
  • For indexed or application-service workflows, use service APIs in this section instead.

​
Protocol boundary

  • In scope: chain state queries and transaction submission patterns.
  • Out of scope: service-specific business endpoints and off-chain workflow APIs.

​
Authentication and endpoints

Authentication depends on node and deployment policy.
  • Check /reference/authentication-matrix for active auth requirements.
  • Check /reference/networks-and-endpoints for network-specific RPC endpoints.

​
Example message shapes

message MsgCreateEntity {
  string creator = 1;
  string entity_type = 2;
  string entity_status = 3;
}

message MsgSubmitClaim {
  string creator = 1;
  string collection_id = 2;
  string claim_id = 3;
}

Troubleshooting

  • connection refused / TLS errors — Wrong host, port, or TLS termination. Confirm the literal in Networks and endpoints and your operator’s current RPC URL.
  • invalid JSON-RPC / parse errors — Request body not valid JSON-RPC 2.0; include jsonrpc, id, method, and params as required by the method.
  • Transaction broadcast failures — Inspect code, codespace, and rawLog. Common causes: insufficient fees, wrong chain-id, sequence mismatch, or missing signer permissions. See Error handling and Claims management.
  • Auth on RPC — Many nodes allow unauthenticated read; writes require a valid signed tx, not an API key. Confirm policy in Authentication matrix.
