Add Shift Protocol TVL adapter #16717

Gloom0x0 · 2025-10-16T18:52:43Z

Introduces ShiftTvlFeed ABI, config for contract addresses, and an index.js adapter to calculate TVL for Shift Protocol vaults. TVL is aggregated from USDC deposits using the latest on-chain data.

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.

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.
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.
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
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
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
No need to go to our discord and announce that you've created a PR, we monitor all PRs and will review it asap

Short Description (to be shown on DefiLlama):
Shift is a DeFi protocol offering a suite of yield products built on top of leading on-chain perpetual futures exchanges (Perp DEXs). Our mission is to make high-yield strategies available to anyone through transparent, on-chain vaults.

The adapter at projects/shift-protocol exports TVL:

base                      500.15 k

total                    500.15 k

+    let totalTvl = 0;

+    for (const address of contractsByChain[chain]) {
+      const contract = new Contract(address, abi, provider);


can we use our SDK here rather than ethers?

If the defillama sdk can create contract interfaces, there is no issue. Beware of the abi that is custom for our contracts.

please check the docs https://docs.llama.fi/list-your-project/submit-a-project and look at other adapters in the repo

+      totalTvl += tvlValue;


please return token balances using api.add() or similar rather than exporting a USD amount

This is not a token amout is the vault tvl trough our tvl oraclefeed.

We need a way to count the tokens deposited to each vault

Pivit to a different calculation for TVL with our share supply.

This is still exporting a USD amount though - we need to export token balances of the deposit tokens

So our situation right now is the following:

we track internally the USD TVL in the system

the way we do this is through Starknet's Library + Paradex API, to know how much Paradex Vault shares our wallet has and multiply that value per the current reported price of the share. The share has no open market, it's a fundamental price/value calculated based on the increasing amount of USD backing the shares.

afaik, there is no single way for us to surface the final result (how much TVL in $) without doing these two steps, as Paradex API by themselves don't offer this possibility, there is no "coingecko" or similar pricing for the underlying asset and no open markets to trade them.

We can share in detail how we calculate it / explain the methodology, would that be okay?

yes please let us know the calculation

please use string form ABI instead - try searching the repo for "function

Our TVL (currently) is defined as circulating liquid receipt tokens (ltPARA) * share price.

We emit ltPARA which is an ERC20 token on Base, against USDC deposits. The deposits then get transferred to Paradex and deposited in the Gigavault (which is their LP/MM vault).

Therefore, for the circulating of supply this is fairly easy, as it corresponds to https://basescan.org/token/0xaf69bf9ea9e0166498c0502af5b5945980ed1e0e

The price is calculated as a fundamental value via: underlying backing / number of circulating shares.

Therefore, as you see, our TVL is essentially calculated as the underlying backing.

The underlying backing is calculated via several steps:

The dust/inactive deposits on base at our wallet: https://basescan.org/address/0x2f8b5f84032c7ffea5a5dc990ce5eb7167d596ed

And the active deposits on Paradex.

Through Paradex APIs we get:

the amount of USDC on the Paradex account

the value of our deposit into the Gigavault (calculated as: number of Gigavault shares * price of one share, both extracted via Paradex APIs), with the numbers of gigavault shares we are holding being extracted through Starknet library

Removed ShiftTvlFeed.json ABI and updated TVL logic in index.js to use standard ERC20 totalSupply and decimals, along with a custom getSharePrice() call. The config.js contract address was updated. TVL is now calculated as totalSupply * getSharePrice (formatted with 6 decimals) for each contract.

Please remove any try/catch

Simplifies error handling for ABI calls in the TVL calculation by removing try/catch blocks and checking for missing outputs instead. Logs warnings and applies sensible defaults when data is unavailable.
