HOT Signer

Functions

• Can sign HOT Quotes for HOT swaps.

Security Model

1. The signer is responsible for market-making for all incoming solver swaps on behalf of the LPs.

2. EOA signers should ensure their private key is managed securely, using industry-leading practices.

Trust Assumptions

All LPs trust the signer to run a competitive market-making algorithm on the backend and ensure their private key is secure.

A bad signer could cause losses to LP funds because of LVR or malicious signer attacks.

Note: The HOT AMM infrastructure is flexible and can support various mechanisms for improving decentralization, fault-tolerance and trust. The signer itself can be an Externally Owned Account (EOA) or a smart contract. While an EOA is simpler to implement and more gas-efficient, it is more centralized and subject to the trust assumptions outlined above. Without any contract changes, one can transition to smart contract-based signers, which are compatible with off-chain batch auctions, decentralized validator sets, validity proofs, multi-signature schemes, and other mechanisms. This flexibility allows the backend to adapt and incorporate multiple decentralized solutions over time, ensuring fair price discovery and robust performance for LPs
