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.
