On-Chain Copy-Trading Bots
High-performance bots that mirror leading wallets on-chain with disciplined risk controls.
The brief
Retail traders wanted to follow proven on-chain wallets without sitting at a screen — but manual copy-trading is slow, emotional and easy to get wrong. The client needed bots that could detect a target wallet's moves and mirror them in seconds, at scale, without ever taking custody of user funds.
The hard part was speed and discipline together: sub-second reaction on Solana, non-custodial signing, and risk controls tight enough that a bad streak or illiquid token couldn't wipe out a follower.
- Mirror target wallet trades with minimal latency on Solana.
- Keep the model non-custodial — users retain control of their keys.
- Enforce position sizing, exposure limits and stop rules per follower.
- Let users filter which wallets, tokens and strategies to copy.
- Handle failed transactions, slippage and congested blocks gracefully.
- Provide a transparent audit trail of every mirrored trade.
Our AI-native approach
We built the execution path in Rust on Solana — event-driven indexing, a low-latency decision loop and signing that stays in the user's wallet. Risk rules sit between detection and execution so every mirror trade is gated before it hits the chain.
Strategy filters and per-user limits were designed into the core flow rather than bolted on, so followers could tune exposure without surrendering the speed that makes copy-trading worthwhile.
What we built
Wallet mirroring engine
Watches target wallets and maps their on-chain activity to follower actions.
Low-latency execution
Rust services on Solana minimise time from signal to signed transaction.
Risk & position limits
Sizing, exposure caps and stop rules gate every trade before it executes.
Non-custodial signing
Users keep keys; the bot proposes trades through permissioned signing flows.
Strategy filters
Followers choose wallets, tokens and rules that match their risk appetite.
Monitoring & alerts
Live dashboards, kill switches and alerts when limits or anomalies trigger.
How we built it
Latency drove every architectural choice — we profiled RPC paths, indexing and the hot loop under realistic load, and hardened the signing path before opening to followers. Security was non-negotiable: minimal contract surface, explicit permissions and independent review of the execution layer.
We shipped incrementally — one wallet mirror path end to end, validated risk gates under live market conditions, then expanded strategy filters and scale. A specialist pod owned bots, infrastructure and on-chain integration together.
How it works
Select
A follower picks wallets and strategy filters to mirror.
Detect
The bot indexes target wallet activity on-chain in real time.
Filter
Risk rules and exposure limits gate eligible mirror trades.
Execute
Approved trades are signed and submitted with minimal delay.
Report
Positions, fills and P&L are tracked with a full audit trail.
The sophistication here is trading systems engineering: squeezing latency out of Solana mirroring without giving up risk discipline or non-custodial trust. A fast bot that ignores limits is a liability; a safe bot that's too slow misses the trade entirely.
Structured risk gates and transparent logging turn 'follow this wallet' from a gamble into a governed product — followers see what happened, why it happened, and can stop it instantly.
The impact
Target wallet moves were mirrored in seconds, not minutes of manual watching.
Followers kept custody of funds while automation handled execution.
Risk limits prevented runaway exposure on volatile or illiquid tokens.
Every mirrored trade stayed auditable with clear filters and kill switches.
