Subject: [PATCH 2/8] test(client): mock HTTP requests in vintage AI client
 tests

- Patch _get_public instead of _get in get_miners tests (client now uses _get_public for reads)
- Use case-insensitive header matching for admin key test (urllib normalizes header names)

+# Bounty #32: RTC/ERG Trading Pair on Spectrum DEX
+
+## Overview
+
+Implementation of RTC token on Ergo blockchain, cross-chain bridge, and Spectrum DEX liquidity pool.
+
+**Bounty:** 150 RTC
+**Status:** Implemented
+
+## Components
+
+### 1. Token Issuance (`ergo-anchor/rtc_token_issuance.py`)
+
+Issues RustChain Token (RTC) as an Ergo native token following EIP-4 standard.
+
+| Property | Value |
+|----------|-------|
+| Name | RustChain Token |
+| Symbol | RTC |
+| Decimals | 6 |
+| Initial Supply | 100,000,000 |
+
+**Usage:**
+```bash
+export ERGO_NODE="http://your-ergo-node:9053"
+export ERGO_API_KEY="your-api-key"
+export ERGO_WALLET_PASSWORD="your-password"
+
+python ergo-anchor/rtc_token_issuance.py
+```
+
+### 2. Bridge Contract (`ergo-anchor/rtc_bridge.py`)
+
+Lock RTC on RustChain, mint eRTC on Ergo. Burn eRTC, unlock RTC.
+
+**Flow:**
+```
+RustChain                           Ergo
+   |                                  |
+   |-- Lock RTC (bridge_locks) ------>|
+   |                                  |-- Mint eRTC (2-of-3 multisig)
+   |                                  |
+   |<-- Burn eRTC -------------------|
+   |-- Unlock RTC ------------------>|
+```
+
+**Usage:**
+```bash
+# Lock RTC on RustChain
+python ergo-anchor/rtc_bridge.py lock --amount 1000 --recipient 9h4...
+
+# Mint eRTC on Ergo (after lock confirmed)
+python ergo-anchor/rtc_bridge.py mint --tx_id <bridge_tx_id>
+
+# Burn eRTC to unlock RTC
+python ergo-anchor/rtc_bridge.py burn --tx_id <bridge_tx_id> --amount 500
+
+# Check status
+python ergo-anchor/rtc_bridge.py status --tx_id <bridge_tx_id>
+
+# List pending bridges
+python ergo-anchor/rtc_bridge.py pending
+```
+
+### 3. Spectrum DEX Pool (`ergo-anchor/spectrum_pool.py`)
+
+Create and manage RTC/ERG liquidity pool on Spectrum DEX.
+
+| Parameter | Value |
+|-----------|-------|
+| Initial RTC | 1,000 |
+| Initial ERG | 67.0 |
+| Price | 1 RTC = 0.067 ERG (~$0.10) |
+
+**Usage:**
+```bash
+# Create pool
+python ergo-anchor/spectrum_pool.py create
+
+# Add liquidity
+python ergo-anchor/spectrum_pool.py add --rtc 500 --erg 33.5
+
+# Check status
+python ergo-anchor/spectrum_pool.py status
+```
+
+## Environment Variables
+
+```bash
+ERGO_NODE=http://localhost:9053          # Ergo node URL
+ERGO_API_KEY=                            # Ergo API key (optional)
+ERGO_WALLET_PASSWORD=                    # Ergo wallet password
+RTC_ERC_TOKEN_ID=                        # Token ID after issuance
+SPECTRUM_API=https://api.spectrum.fi     # Spectrum API endpoint
+SPECTRUM_UI=https://spectrum.fi          # Spectrum UI URL
+BRIDGE_DB=/root/rustchain/bridge.db     # Bridge database path
+```
+
+## Architecture
+
+```
+ergo-anchor/
+├── ergo_miner_anchor.py      # Miner anchor TX (existing)
+├── rustchain_ergo_anchor.py  # State anchoring (existing)
+├── rtc_token_issuance.py     # Token issuance (new)
+├── rtc_bridge.py             # Bridge contract (new)
+├── spectrum_pool.py          # DEX pool (new)
+└── config/
+    └── rustchain.conf
+```
+
+## Security
+
+- Bridge uses 2-of-3 multisig for minting authorization
+- 0.30% bridge fee on lock operations
+- Min/Max lock amounts enforced (1 RTC - 10M RTC)
+- All transactions signed via Ergo wallet
+
+## Verification
+
+1. **Token Issuance:** Check transaction on Ergo Explorer with returned token ID
+2. **Bridge:** Monitor `bridge_locks` table for status transitions
+3. **Pool:** View on Spectrum UI or query via API

+Create and manage RTC/ERG liquidity pool on Spectrum DEX.
+
+Features:
+  - Create initial RTC/ERG pool with target price
+  - Add liquidity to existing pool
+  - Query pool status and balances
+
+Initial Price Target: 1 RTC = 0.067 ERG (~$0.10 at $1.50/ERG)
+Initial Liquidity: 1,000 RTC + ~67 ERG
+
+Usage:
+  python spectrum_pool.py create
+  python spectrum_pool.py add --rtc 500 --erg 33.5
+  python spectrum_pool.py status
