How to calculate TVL for Defillama adapter?

[smol-ninja]

I've been working on adding Sonic to the Defillama adapter and discovered that the current approach for calculating TVL may have been broken after the recent upgrade.

The adapter depends on the following query to pull data:

{
  contracts { id address category }
  assets { id chainId symbol }
}

As pointed out by @gavriliumircea on Slack, the contract entity was removed in the latest update. As a result, the defillama adapter may not be functional anymore. Here is the current code.

Since the contract entity is no longer available, the solution (I can think of) is hardcoding all contract addresses directly. However, that sounds inefficient and not scalable. I also looked at the indexer schema but couldn’t identify a clean alternative for calculating TVL. Also, I think Defillama may not be compatible with envio (as I don't see any envio reference in the defillama sdk) in case there is a relevant entity available in envio.

I would like to get some help here on how to best approach this.

Huh. I thought that that entity was only used for the contract initialization thingy. I didn't know it was used externally.

We will take the path of least resistance and bring back the Contract entity: #202

Great. Thank you.

We brought back the Contract entity in the indexers, and the TVL seems to be working now. Can you confirm @maxdesalle, @smol-ninja?

I don't remember how it looked like when it didn't work.

I think on their dashboard, they use some cached data because the node command in their repo is breaking in its current form since the contract entity now has a different structure than before.

Regardless, its working locally after I made some changes to the adapter code so we are good now.

God it - can you ping someone from DeFiLlama to ask them to invalidate their cache?

The issue was with the adapter. I fixed that and now its all good: https://defillama.com/protocol/sablier
