Draft: AML Delegation to DeFi Pools

There is a looming risk in DeFi concerning real-world assets (RWAs) or security tokens in general and pools holding them (think Uniswap, AAVE, …) regarding Anti Money Laundering (AML) regulation.

Should a court order the token issuer (i.e. Circle) to freeze the holdings of an address that has deposited the funds into a pool (i.e. UniV3-ETH/USDC), that might risk the token issuer having to freeze the whole pool's holdings.

This risk is even amplified in the new Uniswap v4 architecture as all pools' funds will be held

New / Custom SEP-7 URI Types

WHOIS (vendor prefixed)

Stellar URI type to request another party's public key. Can optionally be signed with a HMAC using a secret nonce to protect the response (the data submitted to the callback endpoint) against man-in-the-middle attacks.

Stellar Pre-Authorized Multi-Signature

Abstract

I tried to use pre-authorizeded transactions on Stellar as a replacement for a co-signer signature, but it seems like they don't play terribly well with multi-signature setups.

Scenario

Given:

Sharded Secret Key Storage

Store secret keys on the internet
Authenticate with arbitrary authentication methods to retrieve secret
Trustless: None of the key storage server providers can read the secret
Recoverable funds: Even if authentication credentials are lost, the secret can be recovered
Secure: If a key storage server gets compromised, the attacker will not even know a fragment of the secret
Fault-tolerant: Redundancy fragment allows retrieving the secret even if a server is down
Versatile: Allows storage of arbitrary secrets

React - Functional error boundaries

Thanks to React hooks you have now happily turned all your classes into functional components.

Wait, all your components? Not quite. There is one thing that can still only be implemented using classes: Error boundaries.

There is just no functional equivalent for componentDidCatch and deriveStateFromError yet.
