Linkdrop V2 Spec

To unify all linkdrop types (campaigns, p2p, modules, on-ramps) we need common interface.
This will allow to utilize the same claim code (claim web apps, API, SDK, URI) for all kinds of the linkdrops,
reducing the need to repeat ourselves again and again.

The idea is to allow different ways to generate linkdrops (dashboard, sdk, wallets), but interoperable way to claim all kind of linkdrops.

Linkdrop Escrow Contract Interface:

Ens Login iFrame draft proposal

Abstract

• User enters his ENS (e.g. user.my-wallet.eth)
• Dapp queries the Ethereum blockchain with an ENS to get the provider source URL/IPFS hash and loads the wallet provider in a sandboxed iframe.
• Dapp interacts with the wallet provider via PostMessage interface - https://developer.mozilla.org/en-US/docs/Web/API/Window/postMessage
• Messages between dapp and wallet provider should comply with EIP-1474 - https://eips.ethereum.org/EIPS/eip-1474

Iframe benefits

• Better security: wallet provider code is loaded in a sandbox environment, can't read dapp's localstorage/cookies and can't track dapp location
• Formalized specs: a wallet provider needs to provide a js code that can respond to the eip-1474 messages
