About

The problem it solves ### The problem it solves VaultCircle simplifies collective yield generation in DeFi. It allows small groups or communities to pool assets into shared on-chain vaults that automatically earn yield through trusted strategies like Morpho, Yearn on Katana. Each vault is: * Fully on-chain and transparent * Linked to ERC4626-compliant strategies * Able to donate part of its yield to a chosen address This makes group savings, social investing, or donation-based yield farming safer and easier to coordinate. The vault abstracts away complex interactions, enabling users to earn and contribute collectively without manual management.

How it's made

Challenges we ran into Testing on Tatara required deterministic factory deployments, but the strategies referenced non-existent vaults, causing reverts on “call to non-contract address.” To fix this: * Mock ERC20 tokens and mock Katana vaults were built to simulate real yield flow. * Modular deployment scripts were written for smooth sequential deployment. * Parameterized runbooks ensured repeatable factory-strategy linking. This mock-driven approach allowed the entire system to run cleanly on isolated testnets while keeping deployments predictable and composable.
