Solana Meme Coin Scanner: Velocity Wallet Discovery Rebuild and Reopen

A controlled reopen of the Solana meme coin scanner under the six-wallet ROSTER_C_PRUNED_BEST profile isolates high-conviction momentum from the noise of degenerate capital.

Reconstructing the Velocity Wallet Roster

During the triage session on June 25, 2026, at 07:39 BST, database investigation revealed divergence between original cohort definitions and the live database state. The system database held an inflated copy target roster: VELO had grown to 26 wallets, VELOR to 23, MEDIA_VELO to 26, and MEDIA_VELOR to 19. The active VELO and MEDIA_VELO lists were identical duplicates, violating the strict validation parameters of the initial June operations.

To preserve system state, a safety snapshot was written to the directory /root/backups/pumphouse_strike_wallet_triage_20260625_061438. Unsafe files like scratch_inject_velo.py were quarantined in /root/Pumphouse/quarantine/gemini_20260625_063609.

Replay evaluations within the Pumphouse method show that a restricted roster produces more consistent metrics. The six-wallet ROSTER_C_PRUNED_BEST profile generated 97 paper trades over a seven-day validation window (13.86 trades daily) with a net paper balance change of plus 60.2126 GBP, a 52.58% win rate, and zero losing wallets. The broader ROSTER_D_RESEARCH_PLUS profile produced 152 trades over the same period with a net paper balance change of plus 105.3545 GBP and a 55.26% win rate, but introduced higher execution volatility.

Operational Reopen Profile and System Configuration

Following roster cleanup, the system was brought online under a controlled reopen on June 25, 2026, at 07:56 BST. Systemd drop-in files were updated, specifically /etc/systemd/system/pumphouse-exec-mirror.service.d/zzzz-strike-online-20260625.conf for the mirror runner. Under this profile, the mirror operates on the VELO lane with a 1.00 GBP stake per transaction, a daily cap of 15.00 GBP, and a market capitalization entry band between 3,000 USD and 6,000 USD. The system restricts open trades to six, enforces a drift max of 1.50, and sets sell slippage to 50.

The active state in /var/www/memes/api/exec_live.json at 06:56:13 UTC confirmed execution was armed and pause status was set to false. The status monitor, /root/Pumphouse/services/pumphouse_exec_status.py, was modified to read pause status dynamically. The system separates active lane tracking from legacy execution data. While the VELO lane has six active wallets and zero open positions, the status engine isolates six legacy open positions from the June 10 ELITE configurations to avoid misleading capacity alerts on the Pumphouse dashboard.

Automated Weekly Wallet Discovery Safeguards

To prevent manual configuration creep, weekly automated wallet discovery was established on June 25, 2026, at 08:15 BST. Candidates from a 72-hour read-only scan by /root/Pumphouse/tools/velocity_wallet_fresh_scan_readonly.py are routed through the policy filter /root/Pumphouse/tools/pumphouse_velocity_weekly_discovery.py. This policy restricts candidates to wallets conducting 30 or fewer raw daily buy operations, requiring positive exact replay PnL and verified, repeatable mint signatures.

The validation report at /root/Pumphouse/reports/strike_rebuild/velocity_weekly_discovery_20260625_071048.md evaluated the latest data window, identifying four candidate wallets for paper testing and rejecting 139 high-frequency targets. The audit confirmed that 14 of the original 20-wallet set were held out: seven had negative historical paper performance, and seven had no recent activity. This automated process runs under the systemd timer /etc/systemd/system/pumphouse-velocity-weekly-discovery.timer, scheduled to trigger next on June 28, 2026, to supply new candidates to the Solana holder scanner without mutating active database tables.

Tracking Paper Performance and Exit Boundaries

The memecoin paper demo ledger tracks performance metrics since the 50.00 GBP bankroll reset. Figures recorded at 07:31 UTC show wide variance across the fifteen lanes: BUNDLE_V stands at 497.75 GBP (+447.75 GBP) with a 13.0% win rate on 2,194 trades, followed by BUNDLE at 370.75 GBP (+320.75 GBP, 10.6% win rate on 1,719 trades) and BUNDLE_Q50 at 363.19 GBP (+313.19 GBP, 11.0% win rate on 1,511 trades). Mid-tier velocity lanes include VELOR at 141.48 GBP (+91.48 GBP, 41.0% win rate on 290 trades), FRESH at 90.28 GBP (+40.28 GBP, 26.9% win rate on 840 trades), and VELO at 81.24 GBP (+31.24 GBP, 48.9% win rate on 45 trades). Core performance tracking shows CORE_V at 86.62 GBP (+36.62 GBP, 32.4% win rate on 553 trades) and standard CORE at 54.76 GBP (+4.76 GBP, 31.2% win rate on 572 trades). The lowest-performing configurations remain BW_SENTINEL_SOLO at 48.98 GBP (-1.02 GBP, 28.9% win rate on 714 trades) and ELITE at 27.27 GBP (-22.73 GBP, 9.7% win rate on 540 trades).

These lanes operate under a paper-only model with a 0.50 GBP base stake, except for selected momentum lanes using 1.00 GBP. The exit rules are modeled against public guidelines, including the Pump.fun docs for bonding-curve behavior, to track post-graduation survival. System updates are logged in the Atlas notes and the main FreedomCore research archive.

Caveats and Operational Constraints

Several operational limits remain in place. First, the automated weekly discovery timer is strictly read-only and is blocked from modifying active database tables. Second, historical configurations for all media lanes remain disabled for new entries. Third, while execution is armed for the six verified wallets, wider network-wide tracking remains restricted to paper-only replays. The system is designed to fail-closed immediately if security checks degrade.
