From 9db77a2bf4bb2adebe8b83d2d141e1286b2376ef Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 25 Oct 2025 18:32:48 +0000 Subject: [PATCH] feat(dex): integrate Noble testnet for USDC cross-chain operations MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit integrates the Noble testnet (grand-1) with Sonr's x/dex module, enabling native USDC trading and liquidity operations across IBC-enabled chains. Changes: - Add default params configuration with Noble testnet in allowed connections - Create Noble-specific helper types and functions for USDC operations - Implement USDC conversion utilities (base units <-> USDC decimals) - Add NobleSwapParams and NobleLiquidityParams for structured operations - Update genesis state to use default params with validation - Add comprehensive Noble integration documentation - Create unit tests for params and Noble helpers Noble Configuration: - Chain ID: noble-grand-1 (testnet) - USDC Denom: uusdc (6 decimals) - RPC: https://noble-testnet-rpc.polkachu.com:443 - gRPC: noble-testnet-grpc.polkachu.com:21590 Module Parameters: - Max accounts per DID: 5 - Default ICA timeout: 600 seconds - Min swap amount: 1000 base units - Max daily volume: 1T base units - Rate limits: 10 ops/block, 100 ops/DID/day - Fees: 0.3% swap, 0.2% liquidity, 0.1% orders This integration enables Sonr users to: - Register ICA accounts on Noble testnet - Execute cross-chain swaps with USDC - Provide/remove liquidity in USDC pairs - Trade with slippage protection - Route multi-hop swaps through USDC 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- x/dex/NOBLE_INTEGRATION.md | 361 +++++++++++++++++++++++++ x/dex/types/genesis.go | 7 + x/dex/types/noble.go | 224 ++++++++++++++++ x/dex/types/noble_test.go | 533 +++++++++++++++++++++++++++++++++++++ x/dex/types/params.go | 133 +++++++++ x/dex/types/params_test.go | 311 ++++++++++++++++++++++ 6 files changed, 1569 insertions(+) create mode 100644 x/dex/NOBLE_INTEGRATION.md create mode 100644 x/dex/types/noble.go create mode 100644 x/dex/types/noble_test.go create mode 100644 x/dex/types/params.go create mode 100644 x/dex/types/params_test.go diff --git a/x/dex/NOBLE_INTEGRATION.md b/x/dex/NOBLE_INTEGRATION.md new file mode 100644 index 000000000..98d33757b --- /dev/null +++ b/x/dex/NOBLE_INTEGRATION.md @@ -0,0 +1,361 @@ +# Noble Testnet Integration for Sonr DEX Module + +## Overview + +This document describes the integration of the Noble testnet with Sonr's x/dex module.
