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.

This repo is for TVL adapters. For other metrics such as volume, fees, revenue, aggregators, open-interest, active-users, etc. submit the PR to DefiLlama/dimension-adapters.

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: https://github.com/DefiLlama/DefiLlama-Adapters/discussions/432), if you have trouble with creating the adapter, please hop onto our discord, we are happy to assist you.
4. For updating listing info Please send a mail to [email protected]
5. Do not edit/push pnpm-lock.yaml or pnpm-workspace.yaml files as part of your changes, 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

Agent skill

This repo includes an agent skill at skills/adapter-author/ for AI-assisted DefiLlama TVL adapter authoring. It helps coding agents validate whether a request belongs in DefiLlama-Adapters, choose existing adapter patterns, implement TVL adapters in repo style, run node test.js, and prepare PR metadata. See skills/adapter-author/SKILL.md for usage.

Work in progress

This is a work in progress. DefiLlama aims to be transparent, accurate, and open source.

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. If you run into issues with a chain make sure to update the sdk with npm update @defillama/sdk.

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
