This quest is to migrate the CryptoPunks Subgraph to Squid SDK. The resulting squid should match the GraphQL API of the subgraph as close as possible, by migrating schema.graphql. The judges reserve the right to request improvements afther the initial review of the submission. Reach out to the Discord Channel for any tech questions regarding this quest. Use template squid as a starter.

Ultimately, the solutions are accepted at the discretion of judges following a manual review. This sections is a rough guide that is in no way binding on our side.
Some of the reasons why the solution will not be accepted include:
- squid does not start
- squid fails to sync fully due to internal errors
- batch handler filters are not set up correctly (leads to a late sync failure in RPC-ingesting squids)
- data returned for any query is not consistent with subgraph data
It is desirable that your solution:
- includes a suite of test GraphQL queries that touches every schema entity and, if used, every custom resolver at least once, with corresponding subgraph queries (listing in README is enough)
- has high code quality (readability, simplicity, comments where necessary)
- uses batch processing consistently
- avoids any "sleeping bugs": logic errors that accidentally happen to not break the data
- follows the standard squid startup procedure:
If it does not, describe your startup procedure in the README.
git clone <repo_url> cd <repo_url> npm ci sqd up sqd process & sqd serve
Please test your solutions before submitting. We do allow some corrections, but judges' time is not limitless.
To submit, invite the following github accounts to your private repo : @dariaag, @belopash, @abernatskiy and @dzhelezov.
tSQD rewards will be delivered via the quests page of Subsquid Cloud. Make sure you use the same GitHub handle to make a submission and when linking to that page.
Winners will be listed at the quest repository README. If you do not wish to be listed please tell us that in an issue in your submission repo.

Full startup procedure for newly developed squids:
- Install dependecies:
npm ci- Generate model
sqd codegen- Generate types
sqd typegen- Build the squid
sqd build- Open docker and run:
sqd up- Generate migrations:
sqd migration:generate- Start processing:
sqd process- Start a local GraphQL server in a separate terminal:
sqd serveTypes (./src/abi), models (./src/model) and migrations ('./db') are typically kept within squid repos after they become stable. Then the startup procedure simplifies to
npm ci
sqd up
sqd process &
sqd serve- Docker not installed
