Blueprints & AI tools
Self-serve products, separate from my engagements — production-shaped Vyper 0.4 blueprints and live AI/Web3 tools. Buy instantly or commission a custom build. Need protocol engineering instead? See services →
Buy the blueprint, skip the quarter of engineering
Pre-configured Moccasin/Vyper 0.4 projects — compiling, test-green, and distilled from a live Sepolia DeFi stack. Each ships the contracts, a reference-doc library, and a walkthrough. The fast path to production-shaped Vyper.
6 of 6 shipped · v1.0.0 · 734+ tests green across the line
Every packaged product ships a stateful fuzzer machine — a Hypothesis/Titanoboa rule for every external function and many invariants for every smart contract, driving arbitrary action sequences against the system. Not just unit tests: the property suite ships in the box.
Solidity → Vyper 0.4 & Snekmate Migration
The fastest path from Solidity to Vyper 0.4 — five OpenZeppelin contracts shown before & after, in a project that compiles and tests green out of the box.
- 5 before/after pairs — ERC-20, ERC-721, ERC-4626, two-step ownership, roles + pausable
- Pre-wired Moccasin project — clone, compile, test
- Solidity→Vyper 0.4 pattern catalog + Snekmate module map
- Migration playbook, security notes & Sepolia deploy guide
veForge Tokenomics — Vote-Escrow, Gauges & Bribes
The complete Curve-style ve-tokenomics system, rebuilt in modern Vyper — module-composed, hardened, and test-green out of the box.
- 6 contracts: VotingEscrow, GaugeController, 2 bribe distributors, 2 routers
- Pre-wired Moccasin project + one-command full-system deploy
- 6-doc reference library: decay math, gauge/bribe/emission layer
- Security-notes ledger — every audit finding already closed
Keep — ERC-4626 Multi-Strategy Vault + Tranching
A Yearn-style multi-strategy vault — plus the senior/junior tranching layer plain ERC-4626 doesn't give you — pre-wired and 114 tests green out of the box.
- ERC-4626 multi-strategy vault + senior/junior risk tranching
- 6 contracts incl. Aave V3 & Compound V3 reference adapters
- Pre-wired Moccasin project — all offline, no fork needed
- 6-doc reference library + closed-finding security ledger
SnekSentry — Aave V3 Liquidation Bot Kit
An inventory-funded executor + a tested off-chain bot that get Aave V3's void liquidationCall right where most bots get it wrong. No flash loans.
- Hardened Vyper executor + ~790-line
mypy --strictPython bot - Balance-delta accounting around the void
liquidationCall - Close-factor-aware USD→wei sizing · MEV-protect relay support
- Threat model, going-live runbook, Docker + CI included
Coil — Batch-Auction Intent DEX
A CoW-style intent DEX — off-chain signed orders settled in batches at one uniform clearing price, with EIP-1271, permits, fork-replay protection, and measured solvency.
- ~650-line Vyper 0.4 settlement contract, no third-party Vyper deps
- EIP-712 + EIP-1271 + EIP-2612, fork-replay-protected, partial fills
- 3 hostile mocks (permit, fee-on-transfer, EIP-1271 wallet)
- 6-doc reference library + Coil's own SECURITY.md
TARE — Multi-Collateral CDP Stablecoin
A DAI/LUSD/crvUSD-shaped USD-pegged CDP — redundant Chainlink oracle, bad-debt machinery, Dutch-auction liquidation, sTARE vault, and a Curve PegKeeper.
- 7 contracts: token, engine, oracle, peg_keeper, auction_house, sTARE, splitter
- Multi-collateral registry · primary + fallback feed deviation guard
- Permissionless
settle_bad_debt· soft pause + emergency shutdown - Subject of the public 4-protocol hardening write-up
Every blueprint compiles and ships test-green, distilled from a live Sepolia DeFi stack — self-reviewed, not audited; not a substitute for an independent audit before mainnet. Snekmate (AGPL-3.0) is fetched via mox install, never bundled. Checkout by card via Sell.app or direct crypto (USDC).
