@uniswap/unsupported-token-list


This NPM module and GitHub repo contains the unsupported token list used in the Uniswap interface.

Adding a new chain:

1. Add a new file in src/tokens with the chainname
2. update buildlist to include the chain
3. add a unit test in test/uniswap-unsupported.test.js to verify the chainId is in the list

Adding/updating tokens via DynamoDB script:

Prereqs
- Use Node 20+ locally, or keep Node 18 and use the pinned AWS SDK versions already in package.json
- Set AWS credentials in your shell:
- export AWS_PROFILE=your-profile
- export AWS_REGION=us-east-2

Steps
1. Populate target tokens at the top of src/scripts/addTokensFromDynamo.ts (array of { chainId, address }).
2. Run:
- yarn add-tokens-from-dynamo
3. The script:
- Fetches name, symbol, decimals for those tokens from DynamoDB
- Prints a table to the console
- Upserts those tokens into the corresponding JSON files in src/tokens/ based on chainId
- Normalizes symbols (uppercase, no spaces) to satisfy the token list schema
4. Commit the JSON edits and bump package.json version (the list embeds this semver):
- npm version patch (or minor/major)
5. Open PR and merge to main. CI will build/publish and pin to IPFS.
