Oxium Vaults on Sei Network

[Screpuh]

Oxium vaults use on-chain orderbook market making strategies, which makes it difficult to calculate APY directly from on-chain data alone. The data is spread across multiple transactions, protocols, and off-chain data over time, so we use our own indexing API to handle this complexity.

Why we use our indexing API

• Vault APY comes from orderbook fills that happen across many transactions over time
• Calculating market making performance requires analyzing historical fill events and computing time-weighted returns
• While liquidity sits in the orderbook, unused funds are deployed to staking protocols for additional yield
• This creates multi-protocol positions that need data from orderbook events, staking positions, reward programs, and off-chain data

We run an hourly snapshot service that:

• Fetches TVL directly from vault contracts
• Analyzes historical orderbook performance
• Aggregates yields from lending positions and reward distributions
• Provides a clean APY breakdown

why not from on chain calls?

gm @Screpuh why not from on chain calls?

@slasher125 The main reason we can't get APY directly from on-chain calls is that the data we need isn’t all stored or derivable from chain.

For these vaults, market-making performance depends on orderbook fills that happen across many transactions over time. To calculate APY properly, we have to look at historical fills, compute realized/unrealized pnl, and apply time-weighted returns and prices, which requires aggregating data off-chain.

Secondly, part of the vault’s idle liquidity is deployed into staking protocols, so yield comes from multiple sources. Some of that data (like staking rewards) is provided through third-party integrations rather than directly from on-chain contracts,.
