Tycho RPC

Tycho exposes data through two mechanisms, the RPC and the stream. The RPC provides you access to static data, like the state of a component at a given block or extended information about the tokens it has found. For streaming data, we recommend using the Tycho Client. This guide documents the RPC interfaces.

Token Information

Tycho stream provides only the token addresses that Protocol Components use. If you require more token information, you can request using Tycho RPC's Tycho RPCendpoint. This service allows filtering by both quality and activity.

Quality Token Quality Ratings

The quality rating system helps you quickly assess token's specific properties:

• 100: Normal ERC-20 Token behavior

• 75: Rebasing token

• 50: Fee-on-transfer token

• 10: Token analysis failed at first detection

• 5: Token analysis failed multiple times (after creation)

• 0: Failed to extract attributes, like Decimal or Symbol

The Token Quality Analysis was developed to aid Tycho Simulation in filtering out tokens that behave differently from standard ERC-20 Tokens. The analysis is under constant improvement and can provide wrong information.

Retrieve contract states

post

This endpoint retrieves the state of contracts within a specific execution environment. If no contract ids are given, all contracts are returned. Note that protocol_system is not a filter; it's a way to specify the protocol system associated with the contracts requested and is used to ensure that the correct extractor's block status is used when querying the database. If omitted, the block status will be determined by a random extractor, which could be risky if the extractor is out of sync. Filtering by protocol system is not currently supported on this endpoint and should be done client side.
