An on-chain trading bot trades directly on decentralised exchanges: it watches the chain, decides, and sends its own signed transactions, without an exchange account in between. That gives speed and full control, but also exposes the bot to things a centralised exchange hides: gas costs, failed transactions, front-running and malicious tokens. We build custom bots for EVM chains and Solana that take all of that into account.
Strategies We Build For
- Arbitrage: price differences between pools, DEXs or chains, often executed atomically so the trade only happens if it is profitable.
- Launch and listing detection (sniping): reacting to new pools or liquidity the moment they appear, with safety checks before buying.
- Automated swaps and DCA: scheduled or rule-based buying and selling with price and slippage limits.
- Liquidity strategies: managing concentrated liquidity ranges, rebalancing and fee collection, see DeFi position management.
The strategy is yours; we build the execution, data and safety around it. We do not give trading or investment advice.
What Makes a Bot Reliable
- Fast data: own or dedicated nodes and websocket streams, mempool access where relevant, and indexed data for history.
- Simulation before sending: every transaction is simulated against the current state, so reverts and bad fills are caught before gas is spent.
- MEV protection: private transaction submission and tight slippage, so the bot is not sandwiched.
- Token safety checks: detecting honeypots, sell taxes, blacklist functions and owner privileges before buying.
- Risk limits: maximum position size, daily loss limits, a kill switch and alerts.
- Key management: hot wallets with limited funds, separated from treasury, and keys that never sit in plain text.
How We Build It
Latency-sensitive parts are written in Rust; contracts for atomic execution in Solidity; dashboards and configuration in TypeScript. Strategies are tested on historical data and on forked chains before they trade real funds, then started with small amounts.
Frequently Asked Questions
Which chains do you support?
EVM chains such as Ethereum, Arbitrum, Base and BNB Chain, and Solana. Each chain needs its own data sources and execution approach.
Can the bot run on our own server?
Yes. We can deploy it on your infrastructure, so keys and strategy stay with you.
Is a profitable result guaranteed?
No. We build reliable execution and risk controls; whether a strategy is profitable depends on the market and the strategy itself.
Who owns the code?
Ownership of the source code is set out in the contract, and the code can be fully yours, including documentation and tests.
