Description

Updates the Vaults.fyi provider to use it's new v2 API which updates old action schemas and adds new actions, now using the Vaults.fyi SDK for better type safety.

Tests

Chatbot: langchain-cdp-smart-wallet-chatbot
Network: base
Setup: topped up with USDC and ETH

Prompt: "find me the best APY vault on base" (vaults)

The best APY vault on the Base network is the "40acres USDC Vault" with a 7-day APY of 13.24%. It offers yield from interest paid by borrowers who take USDC loans against Aerodrome veNFT position collateral. The vault currently has about $9.75 million TVL.

You can check it out here: https://app.vaults.fyi/opportunity/base/0xB99B6dF96d4d5448cC0a5B3e0ef7896df9507Cf5

Prompt: "what are my current positions" (positions)

You currently have a position in the "40acres USDC Vault" on the Base network. Here are the details:
- Asset: USDC
- Position value in asset: Approximately 19.9983 USDC
- Vault token balance: 10,960 VAULT tokens
- APY: 13.23%

If you want to know more details or take any action, please let me know.

Prompt: "can you withdraw half of my position?" (transaction_context, execute_step)

To proceed with withdrawing half of your position from the 40acres USDC Vault, I need to calculate the amount to withdraw.
Your vault token balance is 10,960 VAULT tokens. Half of this would be 5,480 VAULT tokens.
I will now check the withdrawal steps and then execute the withdrawal for half the position.

Let me know if you want the data in a different format or if you'd like further details.

Prompt: "how does its apy compare to the benchmarks?" (historical_benchmark_apy)

During October 2025, the 40acres USDC Vault had a 7-day interval APY ranging approximately from 13.45% to 16.77%.

For the same period, the benchmark APY on the Base network (USD benchmark) ranged approximately from 5.67% to 6.19%.

In summary, the vault's APY significantly outperformed the benchmark for October 2025, offering more than double the returns compared to the benchmark average. If you want, I can provide daily detailed comparison data as well.

Prompt: "what is the benchmark apy currently?" (benchmark_apy)

The current benchmark APY on the Base network (USD benchmark) is approximately:
- 1-day APY: 4.73%
- 7-day APY: 4.87%
- 30-day APY: 5.12%

If you want any further information or assistance, please let me know.

Prompt: "do i have any rewards to claim?" (rewards_context)

You have claimable rewards of IPOR Fusion Points (about 417.42 x 10^-12 tokens) on the Gnosis network. If you'd like, I can help you claim them. Let me know!

Prompt: "yeah sure lets claim them!" (claim_rewards) (couldn't claim because I only had some on gnosis but payload was generated properly)

It seems there was an issue with claiming the rewards on the Gnosis network due to network limitations of my current wallet connection. I am unable to claim rewards on that network directly at this time.

You may need to claim these rewards using a wallet connected to the Gnosis network yourself. If you want, I can provide details or guide you through the process.

Let me know how you'd like to proceed.

Prompt: "what assets do i have?" (idle_assets)

You currently have the following assets in your wallet:

1. USD Coin (USDC) - Approximately 9.999 USDC
2. Ether (ETH) - Approximately 0.0005 ETH

If you want to manage any of these assets or need more information, feel free to ask.

If a reviewer needs an API key for review I'm happy to share one.

[phdargen]

Thanks for the update @pawelpolak2, looks good to me!

Could you please also update the typescript/agentkit README accordingly?

Carson gave me an API key but it doesnt seem to work

In vaultsfyiActionProvider.ts , the constructor has a default value, but the factory function requires the config.
Suggest changing to:

export const vaultsfyiActionProvider = (config: VaultsfyiActionProviderConfig = {}) =>
  new VaultsfyiActionProvider(config);

[phdargen]

Most actions require network as a mandatory schema parameter, would suggest to make it optional and default to connected network

[phdargen]

Token amounts are in atomic units. In my experience this often doesn't work well and the LLM wrongly converts the units.
I'd suggest to have token amounts in human-readable format for both tool input and output and convert internally from/to atomic units as needed.

There is already a (currently unused) parseAssetAmount function implemented in utils that might be useful

[pawelpolak2]

I think that would make sense for the transaction endpoints but most are readonly and are going to be used for analytics across all chains and i think making network optional might confuse the agent more than help as it actually is required for vault identification.

I crafted the prompts so the agent understands that its all in atomic units and i found that it actually does really well with parsing those! I tried to avoid parsing them for it since it requires me to know the decimal of asset/LP token which would require additional calls and also i found that atomic units works better for the agent when LP tokens are scaled. Anyway I would keep it in atomic if you don't mind. lmk what you think 😁

I gave Carson a new key. The other one was in fact invalid, my bad.

[phdargen]

Thanks for the updates @pawelpolak2, I tested it out and the actions all work smoothly! Indeed, the prompts make a good job at guiding the LLM how to deal with the units, so we can leave it as is.

Let's get this in @CarsonRoscoe
