Defillama Adapters

Follow this guide to create an adapter and submit a PR with it.

Also, don't hesitate to send a message on our discord if we're late to merge your PR.

If you would like to add a volume adapter please submit the PR here

  • If you would like to add a liquidations adapter, please refer to this readme document for details.
  1. PLEASE PLEASE enable "Allow edits by maintainers" while putting up the PR.
  2. Once your adapter has been merged, it takes time to show on the UI. No need to notify us on Discord.
  3. TVL must be computed from blockchain data (reason: DefiLlama#432), if you have trouble with creating a the adapter, please hop onto our discord, we are happy to assist you.
  4. For updating listing info It is a different repo, you can find your listing in this file: https://github.com/DefiLlama/defillama-server/blob/master/defi/src/protocols/data2.ts, you can edit it there and put up a PR
  5. Do not edit/push package-lock.json file as part of your changes, we use lockfileVersion 2, and most use v1 and using that messes up our CI
  6. No need to go to our discord and announce that you've created a PR, we monitor all PRs and will review it asap

Getting listed

Work in progress

This is a work in progress. The goal is to eventually handle historical data. DefiLlama aims to be transparent, accurate and open source.

If you have any suggestions, want to contribute or want to chat, please join our discord and drop a message.

Testing adapters

node test.js projects/pangolin/index.js
# Add a timestamp at the end to run the adapter at a historical timestamp
node test.js projects/aave/v3.js 1729080692

Changing RPC providers

If you want to change RPC providers because you need archive node access or because the default ones don't work well enough you can do so by creating an .env file and filling it with the env variables to overwrite:

ETHEREUM_RPC="..."
BSC_RPC="..."
POLYGON_RPC="..."

The name of each rpc is {CHAIN-NAME}_RPC, and the name we use for each chain can be found here

Adapter rules

  • Never add extra npm packages, if you need a chain-level package for your chain, ask us and we'll consider it, but we can't accept any npm package that is project-specific
