How to test?

To see that the new entity fetcher URL works follow the below:

1. Run pnpm dev
2. Verify V2 on Ethereum: http://localhost:5001/apps/vendor-finance/balances?addresses%5B%5D=0xC6c48E582405BE32f25EdBa211CCaa820058Cb2f&network=ethereum
3. Verify V2 on Arbitrum: http://localhost:5001/apps/vendor-finance/balances?addresses%5B%5D=0x2a6334c30f36d1eefd64689c590dd199d3475972&network=arbitrum
4. Verify v1 on Ethereum: http://localhost:5001/apps/vendor-finance/balances?addresses%5B%5D=0x245cc372C84B3645Bf0Ffe6538620B04a217988B&network=ethereum
5. Verify v1 on Arbitrum: http://localhost:5001/apps/vendor-finance/balances?addresses%5B%5D=0xD6587a974C7D3ecE23Fa53d5606da6B291311F6f&network=arbitrum

Is there something wrong with the current implementation fetching the balance onchain directly ? @ForrestChew
We don't want to rely on subgraph or any external API for balances

Regarding the balances for both V2 ETH and V2 ARB, there have been no modifications, and they continue to be fetched from onchain as before. However, for fetching the actual pools, we must rely on an external API as there is no onchain method for tracking individual pools.

For both V1 ETH and V1 ARB balances, I'll try and find a way around using an external API. In regards to fetching the pools for V1, it is the same as V2.

I'm wondering if you have Eslint running when coding on studio ? @ForrestChew

[ForrestChew]

So I get red linter errors for two things:

1. @Inject(APP_TOOLKIT)
2. @Inject(VendorFinanceContractFactory)

I ignored these issues however because everything was still working as intended. Also, upon checking other projects within the studio, I noticed the same code and linter errors, leading me to believe it wasn't a real problem.
