Mantle Address Registry Navigator

Overview

Resolve addresses from trusted sources only and fail closed when data is missing or stale. Never synthesize contract addresses from memory.

Source Priority

1. mantle_resolveToken for token symbol/name requests.
2. mantle_resolveAddress for contract key, alias, or label requests.
3. Local registry file: assets/registry.json (fallback/manual cross-check only).
4. If no source provides a verified match, stop and return a blocked result.
5. If MCP tools are unavailable (connection error, tool not found, or offline mode), skip to the local registry fallback (step 3) and cap confidence at medium. Note the tool unavailability in the response notes field.

Lookup Workflow

1. Normalize the request:
   • network (mainnet or sepolia; local registry fallback maps sepolia to testnet)
   • identifier (contract key, symbol, or alias)
   • category (system, token, bridge, defi, or any)
   • optional protocol_id + contract_role when a DeFi request names a protocol but not a registry key
2. Resolve candidates via source priority. For local DeFi fallback, prefer exact key matches first, then exact protocol_id + contract_role.
3. Validate the chosen candidate with mantle_validateAddress and registry metadata:
   • valid_format is true.
   • Address is not the zero address.
   • Entry environment matches request.
   • Entry status is usable (active) for execution.
   • Entry has provenance (source.url and source.retrieved_at).
   • If the request names an intended action, the entry supports that action.
4. Return one canonical result with provenance metadata.
5. If multiple candidates remain ambiguous, ask a clarifying question instead of choosing arbitrarily.
6. Verification requests (user supplies an address and asks if it is official): First resolve the canonical address for the named contract/token using the same source priority (tools first, then local registry). Then compare the user-supplied address against the resolved canonical address. Return the Verification Mismatch format.

Safety Rules

• Never output guessed addresses.
• Never treat user-supplied addresses as trusted without registry/tool verification.
• Mark deprecated or paused contracts as non-executable.
• Never return placeholder/template values from assets/registry.json (for example REPLACE_WITH_EIP55_CHECKSUM_ADDRESS).
• If registry freshness is unknown, label confidence as low and request manual confirmation.
• If a DeFi request names a protocol and multiple active entries exist for that protocol (even if they share the same contract_role), stop and ask which specific contract the user needs. Use the Clarification Needed format and list all matching candidates.

Response Format

Successful Lookup

Address Resolution Result
- identifier:
- network:
- address:
- category:
- status:
- source_url:
- source_retrieved_at:
- confidence: high | medium | low
- notes:

Blocked / Not Found

When no verified entry exists, return this structure instead of guessing:

Address Resolution Result
- identifier: [requested identifier]
- network: [requested network]
- address: BLOCKED
- category: [requested or inferred category]
- status: not_found
- source_url: N/A
- source_retrieved_at: N/A
- confidence: none
- notes: [why lookup failed — e.g., "No verified entry in tools or local registry for this identifier."]

Verification Mismatch (Anti-Phishing)

When the user supplies an address and asks whether it is official, compare against the registry and return:

Address Verification Result
- queried_address: [user-supplied address]
- identifier: [matched registry key, if any]
- network: [network]
- registry_address: [address from registry, or NONE]
- match: true | false
- status: [registry entry status, or not_found]
- source_url: [registry source URL, or N/A]
- source_retrieved_at: [registry timestamp, or N/A]
- confidence: high | medium | low
- notes: [explanation — e.g., "Address does not match the verified Aave v3 Pool entry."]

Clarification Needed

When multiple candidates remain and the request is ambiguous, do NOT pick one. Instead respond with:

Clarification Needed
- identifier: [requested identifier]
- network: [network]
- candidates:
  1. [key] — [label] ([contract_role]) — [address]
  2. [key] — [label] ([contract_role]) — [address]
- question: [ask the user which specific contract they need]
