This article focuses on the design space of post-quantum solutions for Ethereum users, centered on protecting assets and therefore on the execution layer. Our argument, in short: the best answer here is more than a signature, it's a protocol, a set of choices and Ethereum components that have to work together.
NiceTry shows how a Solana PDA can operate as a stable post-quantum smart account using hash-based authorization, onchain verification and relayed execution, without changing the protocol. We demonstrate it on mainnet through transfers, a Jupiter swap, Squads [...]
FIPS 205's SLH-DSA parameter sets are dimensioned for a signature budget no blockchain signer will ever approach, and that generic capacity is paid for in signature size and verification gas. Making the budget explicit and bounded opens a parameter space in [...]

Building a fresh FORS signer on hardware signers can take seconds, stalling the user. The two-forest cache removes that stall by doing the slow work ahead of time, in the background, so the next key is already built when it is needed.
In this article we show a small but useful integration: using NiceTry ERC-4337 accounts as owners of an unmodified Safe multisig. The result is a 2-of-3 Safe operated by FORS+C-authenticated accounts, without teaching the Safe anything about FORS+C.
This post analyzes how post-quantum cryptography affects account abstraction, focusing specifically on the roles of paymasters and bundlers, and considers what happens when, and if, AA shifts to being powered by frame transactions.
Post-quantum security on EVM chains is increasingly moving through account abstraction. As proposals mature, no other practical path has emerged. While building NiceTry, the reference implementation of our Ephemeral Keys Protocol, we began testing frame [...]
NiceTry is our wallet infrastructure project, implementing a quantum-safe design for Ethereum wallets based on ephemeral key pairs and account abstraction. Instead of relying on a single long-lived signing key, the wallet rotates its signer after every [...]
A frame transaction is an ordered sequence of execution steps, each targeting a contract address, carrying an independent data payload, and operating in a designated mode. The node executes frames sequentially within a single transaction context, while the [...]
