Ship the on-chain piece.
Or build it yourself.
Solidity + Rust contract dev built off a live Aave V3 liquidator on Base and Optimism. Hire us, learn from us, or both. Async only — no calls, no sales tag.
Engineering
DLE Engineering
EVM contract development. Liquidation bots, MEV scaffolding, audit support. Async-first, GitHub-native, paid in stablecoins or wire.
For projects that need a working bot, a custom contract system, or audit support. We've shipped a multi-chain liquidator on Aave V3, analyzed Critical-class bugs across Kamino / Morpho / Uniswap V4, and built MEV/arb scaffolding (Artemis pattern). We hand you running code + a runbook your team or agent can operate.
- Turn-key liquidation bots (Aave V3, Compound V3, Morpho Blue, custom): $8k–$15k
- Solidity contracts or small systems with full Foundry coverage: $3k–$12k
- MEV/arb scaffolding (Artemis-style framework, no strategy logic): $12k–$25k
- Audit support / pre-audit review: $200/hr, 8-hour minimum
Specialization
Soroban Specialist
Stellar smart-contract development. Niche premium skill — fewer than 200 production Soroban devs globally. We've shipped one of them.
Soroban's transactional model (footprint declarations, storage TTL, fee-bump structuring) catches Rust generalists. We've shipped a 5-crate Stellar liquidator and know which SDK features are stable vs which will burn you in six months. Compatible with SDF/SCF grant deliverable formats.
- Contract development (testnet + mainnet, integration tests, deploy scripts): $5k–$15k
- Code review / audit (5-signal scoring, written findings, fix-review): $2k–$8k
- Liquidation bot deployment (Blend / custom lending markets): $5k–$12k
- EVM → Soroban migration: $8k–$22k

Liquidation Bot Playbook
14-day playbook + sanitized reference snippets to build a production Aave V3 liquidator on Base or any EVM L2. The gotchas no audit firm wrote down. Self-serve, async support, three tiers.
Self-serve. Written playbook + reference snippets + JSON spec for agent automation. Email support, no SLA.
Reader + async Q&A over email/Signal within 30 days + one round of contract code review before mainnet. 48-hour response SLA.
Builder + full deploy support for one mainnet chain + 30 days of async support + performance review at day 30. Permission to use code commercially.

Bot Catalog
Six Builder-Edition liquidators and MEV-framework listings — Aave V3 on Base / Optimism / Arbitrum, K2 on Stellar Soroban, Kinetic on Flare, and the multi-chain MEV scaffolding. Functional, deployable, stripped of the trade-secret optimizations we run in production. Nothing for sale yet — waitlist open, early-bird pricing locked when each bot ships.
Flagship. Based on the live aave.11 codebase running 24/7 on Base mainnet. Realistic earnings $200–$650/mo per our own deployment.
Same codebase as Base, deployed to OP mainnet. Smaller market, lower noise, same Builder-Edition exclusions.
Configured for Arbitrum; not yet gas-funded. Identical Builder-Edition feature set, awaiting first commitment.
Soroban-specific architecture for the K2 lending market. Rare niche — fewer than 200 production Soroban devs globally. Code in progress.
Compound-fork lending market on Flare. Dual-path Solidity (inventory + flash via SparkDEX V3) with 50/50 auto-compound. Day-1 contract done.

Tools we publish
Proof we know what we're doing. Use them, audit them, fork them.
Paste any wallet address, see live HF + position breakdown + oracle freshness for Aave V3 on Base and Optimism. Read-only. Correctly resolves Chainlink AggregatorProxy → impl (the WSS gotcha we document in the playbook).
Stateless safe-read for Chainlink feeds — staleness + L2 sequencer-uptime + grace-period + non-positive-price guards in one call. 11 passing Foundry tests. Use it as a library reference or call the deployed address directly.
