MevLex Arbitrage Contracts
Every MevLex trade settles through a small stack of deployed, source-verified contracts on Ethereum — two arbitrage contracts (v1.0 and v2.0), a bundle executor, and a shared helper. Nothing here is a claim you have to trust: each address is public on Etherscan, and every bundle it lands is independent of anything we say. The operator wallet that signs those bundles is 0xfc9928…85e535 .
MevLex runs one strategy — on-chain arbitrage — funded either from its own capital (no fee, full spread) or with a flash loan (no capital at risk), whichever nets more. These contracts are how that runs on-chain.
The original flash-loan cross-DEX arbitrage contract. Gas-optimized zero-prefix address.
0x0000…120E49Adds own-funds execution and triangular routing. Etherscan-tagged MEV Bot; the operator’s busiest contract.
0x8146…5b5128Packs the arb legs (plus the flash-loan borrow/repay when used) into one atomic bundle and submits it builder-direct.
0xe253…36Bdd9Shared routing and approvals utility used by both arbitrage versions.
0x3a3a…3cea79Arbitrage v1.0 — the original
v1.0 lives at 0x00000000009E50a7dDb7a7B0e2ee6604fd120E49. Its address is not an accident — the leading zeros make its calldata cheaper on every call, which matters when you are competing for inclusion by the wei. It executes flash-loan-funded, two-leg cross-DEX arbitrage: borrow, swap on the cheap venue, sell on the rich one, repay — all in a single atomic transaction that reverts on any loss so the bot only ever pays gas. It is still live and monitored, kept in the stack for the paths it handles best.
Arbitrage v2.0 — the current release
v2.0 lives at 0x81463B0f960f247f704377661ec81C1fd65b5128 and is the operator's busiest contract — Etherscan tags it a MEV Bot. It keeps everything v1.0 does and adds the piece that defines the current strategy: it can fund a trade from the operator's own capital instead of a flash loan, skipping the provider fee entirely and keeping the full spread. It also solves longer routes — triangular and multi-hop — and covers more venues. On every opportunity it compares own-funds against a flash loan and takes whichever nets more after gas.
v1.0 → v2.0 — what changed
Bundle Executor & Flash Router
Neither arbitrage contract talks to block builders directly. The Bundle Executor (0xe2536231Fc1512bABc8C856AD7499830A936Bdd9) — an EIP-7702 smart wallet — takes the arb legs, plus the flash-loan borrow and repay when one is used, and packs them into a single atomic bundle it submits builder-direct. The Flash Router (0x3a3afa84e98dc97fdc1e4894475a66bd7f3cea79) is a shared routing-and-approvals utility both arbitrage versions call. Together with v1.0 and v2.0, that is the whole stack — four contracts, one operator wallet.
Verify it yourself
You do not have to take our word for any of this. Open any of the four addresses on Etherscan, read the verified source, and watch the bundles land in real time — the same feed the desktop app streams. Performance is a matter of public record, not a screenshot.
Multi-layer sandwich is shipping next as a separate MevLex app, with its own contracts — it is not part of this arbitrage stack.
On-chain arbitrage — funded from its own capital (zero flash-loan fees) or flash loans (zero capital at risk), whichever nets more — runs from managed low-latency infrastructure, every trade settling on-chain and independently verifiable. Backed by a 30-day money-back guarantee.
