You can create and submit an adapter to DefiLlama by following their guide and submitting a pull request (PR) with "Allow edits by maintainers" enabled. Adapters collect blockchain data to calculate metrics like TVL (Total Value Locked), which must be based on blockchain data for accuracy. After merging, your adapter may take time to appear on the UI. For volume or liquidation adapters, submit PRs to specific repositories. Avoid editing certain files like `package-lock.json`. You can test adapters locally and change RPC providers via environment variables. DefiLlama supports contributors with Discord help and aims for transparency and accuracy in DeFi data. This process helps you list your DeFi project and share reliable data with the community.
