No black box. The agent reads Polymarket's public Data API, computes a proportional mirror, and records the position. Every step is observable. Every cent is accounted.
Poll Polymarket's Data API every 12 seconds, per leader. Refresh portfolio value + open positions. Pull new trade activity since the last cursor.
Compute the leader's allocation fraction. Multiply by vault equity and the sizing multiplier. Cap at the per-order maximum. Skip dust.
BUY → open a paper position at the leader's price. SELL → close the same fraction the leader closed. Mark every 15s via the CLOB midpoint.
Pulled from the top of Polymarket's 30-day PnL leaderboard. Portfolio value, every BUY, every SELL — observed and mirrored proportional to allocation.

Every mirror is scaled to the fraction of the leader's portfolio that they risk. A whale playing 0.1% of $1M is mirrored as the vault playing 0.1% of its own book.
Worked example
When the leader later sells, say 60% of the position, the vault closes 60% of its 149 shares — at the price the leader filled at — and books the realized PnL.
Hold $POLY on Solana. Balance snapshots are taken on a fixed schedule. When the vault books a winning close, the gain is distributed proportional to balance × duration.
Hold $POLY in a Solana wallet
Phantom, Solflare, Backpack — any standard wallet.
On-chain balance snapshots
Holdings are read directly from chain on a recurring schedule.
Weighted distribution
Reward = (holding_days × avg_balance) ÷ total_weight × distribution.
Fixed supply of 1,000,000,000 on Solana. PnL distributions, no fee switch, no governance theatre.
