ERC20 support for ANLOG

[0x1100010010]

Implement wrapped ERC20 for $ANLOG to support CEX integrations for TGE:

• Phase 1: Simple ERC20 token contract with mint/burn/upgrade functionalities
• Phase 2: Simple centralized DApp portal for users. to swap between wrapped ERC20 and native timechain $ANALOG tokens
• Phase 3: Trustless mechanism (either using GMP and/or Intents model) to create automated marketplace to support wrapped ANALOG tokens available across various chains with easy instant swaps across chains

Let’s nail down the requirements for the Phase-1:

Initially Avneet proposed to target ERC20 implementation which

1. Has centralized minting,
2. Is pausable,
3. Is upgradeable.

For pp.1-2 Avneet’s proposal is to use OZ’s ERC20PresetMinterPauser preset.
For p.3 Avneet proposes to use TransparentUpgradeableProxy

Immediate question that arises here is: why TransparentUpgradeableProxy is preferred over UUPSUpgradeable pattern?
The difference between the two is described here, with tl;dr quoted below:

• TransparentUpgradeableProxy: A proxy with a built in admin and upgrade interface.
• UUPSUpgradeable: An upgradeability mechanism to be included in the implementation contract.

@foravneet could you please share your reasoning behind the choice you’ve made here?

@agryaznov Any upgradable mechanism Research/Engineering sees fit is fine by me. That was just a example I quoted with the point being there are existing standard OZ templates that will make it fast for us to implement
