Uniswap V3 Contract Calls, Token Swaps, and Multi-Hop Routing

Summary

This document describes a platform library for interacting with Uniswap V3 and other Web3 contracts. It explains how to call standard token methods, register an ABI for other contract methods, invoke node RPC methods, encode and decode structured values, and supply payable amounts or transaction options. The examples cover reading token balances and pool prices, approving tokens, swapping between tokens, and routing through multiple assets.

The template also outlines token registration, pool lookup, price calculation from pool state, and use of a wallet key to sign transactions. It is primarily an integration and execution reference rather than a trading signal or tested strategy. The examples show how calls are assembled, but they do not report slippage, gas costs, transaction success rates, or backtest performance. On-chain prices and swaps depend on pool liquidity and execution conditions, so the sample calls alone do not establish profitability or safe operating parameters.

Key ideas

• Standard token methods can be called directly, while other contract methods require ABI registration.
• The interface supports RPC calls, transaction configuration, and structured data encoding and decoding.
• The library demonstrates retrieving pool prices and balances and performing token swaps.
• Multi-hop routes can express a sequence of token conversions through intermediate assets.
• The examples provide integration guidance but no evidence of trading performance or execution quality.
