AgaPay
Agapay (from Filipino agapay, "to walk alongside") is a non-custodial, on-chain savings and smart spending vault protocol built on Arbitrum. It lets individuals and groups lock funds into a smart contract with a beneficiary list, a due date, and optional drip-release scheduling — no bank, no counterparty, no trust required. The contract enforces the terms. A keeper triggers release; fees are transparent and configurable at deploy time. The frontend connects via RainbowKit + wagmi — users bring their own wallet.

Sự miêu tả
**Problem:** In many communities, savings are informal, trust-based arrangements that break down when members default, disappear, or dispute amounts. There is no self-enforcing primitive for group savings on-chain.
**Solution:** Agapay vaults are immutable savings agreements on Arbitrum:
- **Standard vault** — funds locked until a due date; released in one shot to one or more beneficiaries by a keeper.
- **Drip vault** — funds released in fixed installments at a configurable interval (daily, weekly, monthly). Each installment is capped at the vault's current balance.
- **Target gating** — vaults can require a funding target to be met before release is allowed.
- **Fee model** — a platform fee (bps) and an optional keeper tip (bps) are deducted from each release, remainder goes to beneficiaries according to their share split.
The contract is **UUPS-upgradeable** (OpenZeppelin), deployed behind a proxy so the implementation can be patched without migrating vault state.

Smart Contract)
- `AgapayVaults.sol` — UUPS upgradeable vault factory
- `createVault(name, token, target, dueDate, requireTarget, beneficiaries[], shareBps[])` — standard vault
- `createDripVault(name, token, target, dueDate, intervalSeconds, dripAmount, requireTarget, beneficiaries[], shareBps[])` — drip vault
- `fund(id, amount)` — ERC-20 deposit
- `release(id)` — one-shot release with fee deduction
- `releaseDrip(id)` — interval-based partial release
- `refund(id)` — returns balance to funder when conditions aren't met
- `MockUSDC.sol` — ERC-20 test token with public `mint()`
- **Test coverage: 23/23 tests passing, 95.58% line coverage** (Foundry)
- `via_ir = true` enabled to resolve stack-too-deep on `releaseDrip`

Agapay is currently pre-revenue and not seeking external funding at this stage.
The project was built as a public-good savings primitive. Potential monetisation paths, if the protocol gains adoption:
- Protocol fee: 0.5% on release (already implemented, configurable at deploy)
- Keeper tip: 0.1% on release (goes to the address that triggers `release()`)
- Managed vaults: a hosted keeper service that auto-releases on schedule for users who don't want to self-keep
No tokens, no DAO, no roadmap promises. The contract is deployed and functional on two Arbitrum chains. This submission is the working product.
