fix(snowbl-capital): migrate to new vaults (USDC/ETH/BTC)

[estebgonza]

Snowbl Capital migrated its on-chain contracts. The previous single USDC vault sSnowbl (0xd61b…06e8) is retired.

This returns one pool per new Base ERC-4626 vault, each with its own underlying decimals and USD price:

Pool	Vault	Underlying	Decimals
USDC	0x0e1a8354e10057092ecb7218b784c0c21710db91	USDC	6
ETH	0xffa67bd20e656f1c7873525df81728e9d26c8ee2	WETH	18
BTC	0xf423393e84ca810e1955a7806d1cd84d18099809	cbBTC	8

Verified locally against Base mainnet — the adapter returns 3 pools with correct TVL and price-per-share.

Summary by CodeRabbit

• New Features

  • Added support for multiple Snowbl Capital ERC-4626 vaults (USDC, WETH, cbBTC) on the Base chain.

• Improvements

  • Updated APY and TVL calculations to use live underlying token pricing and return accurate per-vault metrics.
  • Added validation to surface an error when required underlying token prices are missing or invalid.

Review limit reached

@estebgonza, we couldn't start this review because you've reached your PR review rate limit.

More reviews will be available in 1 minute and 40 seconds. Learn how PR review limits work.

Your organization has used up its prepaid credits, and credit purchases are no longer available. Enable the review add-on in the billing tab to keep reviews running — you're only billed for reviews past your plan's rate limits ($0.25/file).

⌛ How to resolve this issue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based credits.

🚦 How do rate limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan refill rate.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, the refill rate gradually slows as usage increases. The highest same-day bursts are limited more strictly.

Please see our Fair Usage Limits Policy for further information.

📝 Walkthrough

Walkthrough

The Snowbl Capital adaptor is expanded from a single hardcoded USDC vault to three ERC-4626 vaults (USDC, WETH, cbBTC) on Base. A vaults array replaces the single vault config, and apy() now fetches underlying token prices via utils.getPrices and computes per-vault tvlUsd using each vault's specific decimals and token price.

Changes

Snowbl Capital Multi-Vault Expansion

Layer / File(s)	Summary
Vault config array and apy computation rework src/adaptors/snowbl-capital/index.js	Adds CHAIN constant and a vaults array with USDC, WETH, and cbBTC vault metadata (address, symbol, underlying token, decimals, poolMeta). Reworks apy(timestamp) to fetch underlying token prices once via utils.getPrices, then iterates over vaults to fetch ERC-4626 info and compute tvlUsd as (tvl / 10**decimals) * price per vault, replacing the previous single-vault fixed-decimals approach.

Poem

🐰 Three vaults now bloom where one once grew,
USDC, WETH, cbBTC too!
With prices fetched and decimals right,
The TVL shines in accurate light.
Hop hop hooray for Base chain gains! 🎉

price is undefined or null, either skip processing the current vault (continue
to next iteration) or return early from the function. Only proceed to compute
the tvlUsd value if the price is confirmed to exist and is a valid number,

hey
I don't think the tests failures are from the adapter
the first CI RPC (base.publicnode.com) isn't an archive node, so the 24h-ago convertToAssets call returns empty data and the sdk throws that fragment.format error. Vaults respond fine on archive RPCs on my side
