Please enable "Allow edits by maintainers" while putting up the PR.


  • If you would like to add a volume/fees/revenue adapter please submit the PR here.
  • If you would like to add a liquidations adapter, please refer to this readme document for details.
  1. Once your adapter has been merged, it takes time to show on the UI. If more than 24 hours have passed, please let us know in Discord.
  2. Sorry, We no longer accept fetch adapter for new projects, we prefer the tvl to computed from blockchain data, if you have trouble with creating a the adapter, please hop onto our discord, we are happy to assist you.
  3. Please fill the form below only if the PR is for listing a new protocol else it can be ignored/replaced with reason/details about the PR
  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

methodology (what is being counted as tvl, how is tvl being calculated):

TVL counts tokens where collateral is custodied: ICP-native tokens on ICP chain, and EVM-native tokens locked in the locker contract on their respective EVM chains.

  • ICP chain: Sum of all native ICP tokens: ICP, ckBTC,
    BOB, CHAT, GLDT.
    • EVM chains: Native tokens locked in OneSec bridge contracts on each chain:
      • Ethereum: USDC, cbBTC, USDT
      • Arbitrum: USDC, cbBTC
      • Base: USDC, cbBTC

There should be no doublecounting within a single protocol. Please only count TVL on the chains where collateral is custodied. If this is on EVM, please use our SDK to count the balances on chain

Thanks @waynebruce0x, added SDK to query balance in the locker contract, 0x70AE25592209B57F62b3a3e832ab356228a2192C.

There's no ADDRESSES.arbitrum.cbBTC so we re-used ADDRESSES.ethereum.cbBTC instead for Arbitrum.
