GRU Guide

A user-facing summary of the GRU standards, transport posture, and x402 readiness model, with concrete places to inspect those signals on live token, address, and search pages.

What The Explorer Is Showing You

The explorer now distinguishes between canonical GRU money surfaces on Chain 138 and wrapped transport assets used on public-chain bridge lanes. It also highlights when a token looks ready for x402-style payment flows.

You can inspect these signals directly on live examples such as cUSDT, cUSDC, and related GRU-aware search results under search.

A practical verification path is: open a token page, confirm the GRU standards card, check the x402 and ISO-20022 posture badges, inspect the sibling-network entries under Other Networks, and then pivot into a related transaction to see how GRU-aware transfers are labeled in the transaction evidence flow.

Standards Summary

Base token profile
Canonical GRU v2 base tokens are expected to expose ERC-20, AccessControl, Pausable, EIP-712, ERC-2612, ERC-3009, ERC-5267, deterministic storage namespacing, and governance/supervision metadata.
x402 readiness
In explorer terms, x402 readiness means the contract exposes an EIP-712 domain plus ERC-5267 domain introspection and at least one signed payment surface such as ERC-2612 permit or ERC-3009 authorization transfers.

Example Explorer Surfaces

Token detail
Open cUSDT or cUSDC to inspect the GRU standards card, x402 posture, ISO-20022 posture, and sibling-network mappings.
Search
Use search for cUSDT to verify that direct token matches and curated posture cues are visible on first paint.
Transactions
Open any recent transfer from the token page and look for GRU-aware transfer badges and the transaction evidence matrix on the transaction detail page.

Chain 138 Practical Reading

A token can be forward-canonical and x402-ready even while older liquidity or transport lanes still run on a prior version. That is why the explorer separates active liquidity posture from forward-canonical posture.

The most important live examples today are the USD family promotions where the V2 contracts are the preferred payment and future-canonical surface, while some V1 liquidity still coexists operationally.

On token pages, look for the GRU standards card, x402 posture badges, ISO-20022 badges, and sibling-network references. On transaction pages, look for GRU-aware transfer badges and the transaction evidence matrix.
