Automating Curve Pool Limit-Style Swaps with FMZ and Encrypted Keys

Summary

This tutorial adapts a Curve stablecoin-pool trading idea for the FMZ Web3 interface. It outlines encrypting a wallet private key offline, storing the encrypted value through a protected strategy parameter, and decrypting it at runtime before loading it into the exchange object. The strategy registers a pool ABI, reads token metadata and balances, and queries the pool for estimated swap output.

For the sDAI/sUSDe pool, it monitors an assumed sDAI acquisition cost and calculates potential conversion profit from a fixed input amount. A threshold and balance check identify when a swap might be worthwhile, while the actual trade call is left commented as a demonstration. The article shows how contract reads, wallet handling, and swap execution fit together, but it supplies no backtest, realized trading results, or systematic treatment of gas, slippage, and transaction failure. Its key caveat is operational: the example’s trading action is explicitly presented as something to test cautiously, and the assumed entry cost affects the profit calculation.

Key ideas

• The tutorial combines FMZ’s Web3 exchange interface with Curve pool contract calls to monitor a token conversion.
• It describes offline private-key encryption and runtime decryption before loading the key into the trading environment.
• Pool metadata and wallet balances are queried to identify the two stablecoin tokens and available inventory.
• Estimated swap output is compared with an assumed acquisition cost to flag a possible trade.
• The example leaves execution disabled and provides no performance evidence or full accounting for transaction costs.
