# Summary

BitSave is a non-custodial, on-chain savings protocol that enables users to create time-locked savings positions using ERC-20 tokens under transparent, deterministic rules enforced by smart contracts. The protocol is built around a parent–child contract architecture that prioritises fund isolation, minimal custody risk, and predictable savings behaviour.

Each user interacts with BitSave through a dedicated child contract, ensuring that savings are never pooled and that ownership, custody, and lifecycle management remain localised to the user.

### Key points:

* Savings are time-locked and non-custodial — users create on-chain savings positions with optional early withdrawal penalties, enforced entirely by smart contracts.
* No pooled funds or shared vaults — each user has a unique ChildBitsave contract, and savings are never commingled with other users’ funds.
* Parent contract coordinates, not custodies — the Bitsave contract handles registration, routing, fee enforcement, and protocol-wide accounting, but does not retain long-term custody of user assets.
* Child contracts hold and manage funds — all savings data, including principal, maturity, penalties, and tracking points, are stored and executed within user-specific child contracts.
* Fund flow is deliberate and constrained — funds are routed through the parent contract only transiently and immediately forwarded to the user’s child contract within the same operation.
* Withdrawals are deterministic — withdrawing at maturity returns the full principal, while early withdrawals apply the configured penalty, with execution handled directly by the child contract.
* ERC-20 savings assets are supported — the protocol can support any ERC-20 token, with frontend-enabled tokens available per network.
* Architecture is simple, auditable, and transparent — BitSave minimises system complexity by reducing contract surface area and isolating execution paths.<br>

In summary, BitSave provides a predictable and transparent savings primitive for on-chain users who value fund isolation, clear custody guarantees, and disciplined savings mechanics over pooled capital efficiency or complex financial strategies.
