Symmio, Staking and Vesting
Symmio is a permissionless OTC derivatives protocol and clearing layer. This contest focuses on peripheral contracts for our governance token.
Details
Scope
On what chains are the smart contracts going to be deployed?
Base
If you are integrating tokens, are you allowing only whitelisted tokens to work with the codebase or any complying with the standard? Are they assumed to have certain properties, e.g. be non-reentrant? Are there any types of weird tokens you want to integrate?
Only whitelisted tokens can work with the codebase, and these include stable-coins such as USDC, USDT, and USDE and Tokens like SYMM.
Are there any limitations on values set by admins (or other roles) in the codebase, including restrictions on array lengths?
All restricted roles are trusted. For example, in the staking contract, the number of reward tokens will not exceed 10–20.
Are there any limitations on values set by admins (or other roles) in protocols you integrate with, including restrictions on array lengths?
No
Is the codebase expected to comply with any specific EIPs?
EIP-1967
Are there any off-chain mechanisms involved in the protocol (e.g., keeper bots, arbitrage bots, etc.)? We assume these mechanisms will not misbehave, delay, or go offline unless otherwise specified.
No
What properties/invariants do you want to hold even if breaking them has a low/unknown impact?
No
Please discuss any design choices you made.
In the staking contract, if no tokens are staked, rewards will not be distributed, nor will they be carried forward to the next phase of distribution. In such scenarios, the admin will withdraw those rewards and redistribute them into the staking contract once some tokens are staked. Additionally, the vesting contract will interact with Balancer V3 pools to add liquidity to the 80-20 SYMM-USDC pool.

Additional audit information.
We need to identify any vulnerabilities that could allow attackers to drain the contracts or disrupt the system's functionality in any way.
