Overview

Indexing Templates​

Indexing Templates are the foundation from which interpretation is built.

Indexing templates are their core are simple JSON files - and are formatted around different standards/types. You can view an example of a JSON file event interpreter here.

There are 2 main types of indexing templates:

  • Event Interpretation
  • Position Interpretation

Event Interpretation​

Event Interpreters are used on onchain transactions to translate them into human-readable output and augment them with contextual, and often off-chain, information.

You can read more about Event Interpreters here.

Position Interpretation​

Position interpreters are used to index app-centric balances for users. This can be USDC lent on Aave (aUSDC), or a liquidity position for USDC/ETH you hold on Uniswap V2, or a staked token held in a contract. The large majority of these positions do not have a market price and are not tradeable; rather, they have a redeemable price to unlock an underlying token. To surface these to users, we first need to interpret the contract interface that manages these positions.

Future​

One of the main benefits of working with indexing templates is that rather than having flexibility at the base layer, e.g. a sandbox, flexibility is maintained with the creation of new indexing templates. Anyone can create a new template, and as long as an indexer can read the instructions, it can be directly ingested by the protocol via a soft social consensus - in a similar way that ERC20 is an offchain consensus as to how tokens should be built and structured.

We currently are working on the following templates:

  • Price Interpreters: Index prices for any AMM
  • NFT Marketplace Interpreters: Index sales for any NFT marketplace
