Check if a miner is eligible for epoch lottery rewards. Args: miner_id: The miner wallet address to check eligibility for. Returns eligibility status, required attestation info, and current epoch enrollment status.
AI agents call rustchain_lottery_eligibility to retrieve information from RustChain + BoTTube MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries blockchain state to determine eligibility for lottery rewards. It takes a miner_id as input and returns informational status about eligibility, attestation requirements, and enrollment—all read-only operations. There is no capability to modify wallet state, execute transactions, or trigger external operations.

PolicyLayer is an MCP gateway — it sits between your AI agents and RustChain + BoTTube MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for rustchain_lottery_eligibility:
{
"version": "1",
"default": "deny",
"tools": {
"rustchain_lottery_eligibility": {}
}
