fix: update USDC address on Celo Alfajores testnet #7704

Closed arthurgousset closed 1 month ago

arthurgousset commented 2 months ago

Currently, the USDC address specified for Celo Alfajores testnet is incorrect.

https://github.com/Uniswap/interface/blob/1ffb97086790de08b503311e85306223e9427c8b/apps/web/src/constants/tokens.ts#L481-L482

The correct USDC addresses are:

  1. Celo (mainnet): 0xcebA93...
  2. Celo Alfajores (testnet): 0x2F25de...
- [ChainId.CELO_ALFAJORES]: USDC_CELO.address,
+ [ChainId.CELO_ALFAJORES]: USDC_CELO_ALFAJ0RES_NATIVE.address,
  export const USDC_CELO_NATIVE = new Token(ChainId.CELO, '0xcebA9300f2b948710d2653dD7B07f33A8B32118C', 6, 'USDC', 'USDC')
+ export const USDC_CELO_ALFAJ0RES_NATIVE = new Token(
+  ChainId.CELO_ALFAJORES,
+  '0x2F25deB3848C207fc8E0c34035B3Ba7fC157602B',
+  6,
+  'USDC',
+  'USDC CELO Testnet'
+ )

TLDR:

  1. Uniswap Labs will host the Celo subgraph used in production, and
  2. Uniswap Labs will own and maintain the v3-subgraph repo that generates the subgraph.

On that basis, community members can request new tokens to be whitelisted by opening a PR in the v3-subgraph repo.

@mzywang expects the new Celo subgraph will be live and used in production in the order of "weeks" (not days or months).

For future reference:

  • The subgraph affects optimal order routing, Uniswap uses the subgraph for pool discoverability and ranks pools based on TVL.
  • If the subgraph is down (as is the case right now for the one on the hosted service), a static list of tokens is used to determine routes defined in the uniswap interface.

On that basis, I'll close this PRs, since all work streams here are and will be owned by Uniswap.
