Fabrknt
Reth, Revm, Alloy — for on-chain financial systems.
Most modern L1s run on the Reth/Revm/Alloy stack, yet its implementation layer is still under-appreciated. Fabrknt builds the financial-systems layer on it — the accounting, evaluation, and training the Rust-EVM L1 era will need.
The stack behind modern L1s
Reth, Revm, and Alloy — Paradigm's Rust-Ethereum stack — increasingly underpin new high-performance L1s, from HyperEVM to Tempo and a growing list. The execution layer gets the headlines; the implementation layer that actually runs them is still under-appreciated.
We build on it ourselves
Not a survey of the space — our own production code. rdk (the Reth DeFi Kit) implements DeFi L1 primitives — CLOB, funding, oracle, liquidation, clearing — on Reth/Revm/Alloy, open-source and test-covered. Intentio runs on the same foundation; Dojo teaches it from the source.

Book on-chain transactions right. Ledger, Audit, and Tax read from one canonical record — reconstruct what each transaction economically was, or abstain instead of mis-booking.
