Anyenk · ● Live in production
Non-custodial multisig smart-account wallet
Account-abstraction wallet for companies: a customer-defined quorum (N of M or N of N) plus one of two independent custody keys (AWS KMS and a neutral third party) must agree. Enforced on-chain by a weighted validator; no single party can move funds alone.

Jones DAO · ● Live on 7 chains
Smart LP — automated concentrated liquidity
Hands-free management of Uni V3-style positions with volatility-based ranges and auto-compounding. An abstraction layer lets us add or remove exchanges and blockchains with minimal effort — live on 7 chains and 8 exchanges.

jUSDC & jGLP leveraged vaults
Two vaults working in tandem: jGLP borrows USDC from jUSDC to lever its GLP position and shares the yield back — a stable USDC yield without delta-neutral hedging costs. Peaked at ~$20M TVL. Later rebuilt jUSDC as a standalone ERC-4626 lending hub for GMX V2 strategies (jGM, wjGLV).

jAURA — auto-compounding AURA strategy
Deposit AURA once; the strategy locks it as vlAURA, optimizes votes through Hidden Hand, sells rewards and compounds them back. Two vaults: jAURA for maximum yield, and wjAURA, a composable liquid staking token with its own Balancer 80/20 pool.

Metavaults — one LP, three market views
An LP token split into Bull, Crab and Bear ERC-4626 vaults that farm and auto-compound, with Bull and Bear buying calls or puts every epoch (Dopex SSOV, Valorem). Behind it, an ERC-2535 Diamond router whose facets resolve through upgradeable beacons.
