• 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

Short Description (to be shown on DefiLlama):

LinkDeFi is a yield protocol that routes USDC on Base into a Split ERC-4626 vault, allocating deposits across multiple underlying strategies to optimize yield.

Token address and ticker if any:

No protocol token yet (vault uses USDC as the underlying asset).

Category (full list at https://defillama.com/categories) *Please choose only one:

Yield Aggregator

Oracle Provider(s): Specify the oracle(s) used (e.g., Chainlink, Band, API3, TWAP, etc.):

N/A – TVL is computed directly from on-chain balances without using an external oracle.

Implementation Details: Briefly describe how the oracle is integrated into your project:

N/A

Documentation/Proof: Provide links to documentation or any other resources that verify the oracle's usage:

N/A

forkedFrom (Does your project originate from another project):

None (custom Split ERC-4626 vault implementation).

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

TVL is calculated as the totalAssets() value of the Split4626 vault on Base (0x806Ea0e218d24410e24533fB68810440E3b618e1), counting the underlying USDC returned by asset() as TVL. Unclaimed rewards or protocol-owned liquidity are not double-counted.

Please revert changes to package.json / package-lock.json

The adapter at projects/linkdefi exports TVL:

base                      46.00

total                    46.04 

[AES-256-2]

all ok?

[AES-256-2]

Currently this adapter only includes our Split4626 USDC vault on Base. As we launch additional vaults on Base and other chains, we’ll extend this adapter to cover those as well.
