SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires altomoney-sdk, pydantic, typing, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill simplifies complex off-chain Alto protocol calculations, enabling users to quickly perform market, position, and vault computations with precision and efficiency.

Core Features & Use Cases

  • Market Calculations: Accrue interest, compute liquidity, and determine LTV and health factor for markets.
  • Position Analysis: Assess position health, LTV, and liquidation quotes.
  • Vault Accounting: Calculate APY, liquidity, and share conversions for ERC-4626-style vaults.
  • Use Case: For a lending protocol entity like a vault, this Skill can compute the interest accrual, liquidity, and the maximum borrowable amount given a specific position.

Quick Start

Use the alto-sdk skill to compute the interest accrual for the market at the given timestamp.

Frequently Asked Questions about alto-sdk

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I calculate interest accrual for a lending protocol market off-chain?

You can compute interest accrual by providing input snapshots of the market state at a specific timestamp to a Python-based tool replicating on-chain smart contract arithmetic. This Skill uses big integer math with fixed-point precision to ensure the off-chain calculation matches the lending protocol's exact path.

How do I perform position analysis and compute liquidation quotes for a lending protocol?

You perform position analysis by feeding position and market state snapshots into an off-chain calculator that replicates smart contract arithmetic. This Skill computes position health, loan-to-value ratios, and liquidation quotes using Python big integer math with fixed-point precision.

Can I compute ERC-4626 vault APY and share conversions off-chain using Python?

Yes, you can compute ERC-4626-style vault APY, liquidity, and share conversions off-chain using Python. This Skill performs vault accounting by replicating the on-chain smart contract arithmetic paths using big integer math with fixed-point precision.

Does this off-chain lending protocol calculator require specific input data formats?

Yes, this off-chain lending protocol calculator requires input snapshots of the on-chain market, position, or vault state. It uses these snapshots to execute smart contract arithmetic paths in Python, ensuring fixed-point precision for accurate simulations, analytics, and parity checks.

What is the best way to run parity checks against lending protocol smart contracts?

The best way to run parity checks is to use an off-chain Python tool that replicates exact on-chain smart contract arithmetic paths with fixed-point precision. This Skill uses input snapshots to perform big integer calculations, ensuring your off-chain analytics match the lending protocol's actual state.

When should I not use an off-chain Python SDK for lending protocol market calculations?

You should not use an off-chain Python SDK for lending protocol market calculations if you lack the required input snapshots of the on-chain state. This Skill depends on accurate snapshot data to replicate the smart contract arithmetic paths with fixed-point precision; without it, the calculations will be invalid.
