Milestone 2 (Updated) (Estimated 20–30 days) Develop split routing algorithms and core routing logic.

(Estimated 7 days) Upgrade token USD pricing logic to split-based quoting, ensuring displayed prices better reflect actual swap execution prices.

(Estimated 5 days) Fully migrate API to Redis caching and integrate Cloudflare global acceleration. Current quote latency: 3–4 seconds → Target: 1–3 seconds.

(Estimated 7 days) UI improvements:

Display transaction history

Support permit-based approvals

Redesign routing display module (to support split routing visualization; current display only reflects single-path routes)

(Estimated 7 days) Router contract governance upgrades:

The Entered contract becomes upgradeable only (e.g., v2, v3), and deployed versions cannot be overwritten

Introduce a 3-wallet multisig, requiring 2-of-3 signatures for any admin operation

Implement a 72-hour timelock for all admin functions (“request + confirm” pattern; confirmation must be executed by a different signer to mitigate single key compromise risk)

Extend the protocol fee timelock on Rootstock: no protocol fee changes allowed before 2028 (based on current timeline, all milestones are expected to complete by September 2026)

Audit planning (to be delivered in Milestone 3):

Engage multiple audit firms to obtain quotations

Apply for third-party audit grants (e.g., https://atlas.optimism.io/missions/audit-grants)

Outcome: determine audit scope, cost, availability of external funding, and finalize the audit plan.

Milestone 2 will define and establish a concrete audit plan (scope, provider, and timeline), which will be a prerequisite for execution in Milestone 3.

This milestone addresses the priority of split routing and significantly mitigates the risks associated with Router administrative control. It also delivers a concrete audit plan for Milestone 3.

The multisig structure will initially be managed by the core team, with additional signers introduced over time to reduce unilateral control risk.

Split Routing Validation The main challenge of this milestone lies in the split routing algorithm, as there is no standard solution and it requires extensive computation to determine optimal path allocation and proportions.

To validate the implementation:

A public comparison page will be built using both SwaptoX API and OpenOcean API

Identical inputs (token pair and amount) will be used for fair comparison

At least 30 different test scenarios will be included, covering:

Various trade sizes (e.g., 0.1 BTC, 0.5 BTC, 1 BTC, 2 BTC, etc.)

Multiple token pairs (e.g., BTC → USDC, BTC → USDT, USDT → BTC, etc.)

Each page refresh triggers a new round of live quotes

Tests will be conducted across multiple blocks and time intervals to reduce the impact of short-term market fluctuations
