3 Ethereum standards authored.
Plus ERC-8203 in progress.
I'm Adam Boudjemaa. I authored 3 Ethereum standards: named author (1 of 5) of ERC-3643 (T-REX, Final), first author of ERC-6960 (Dual Layer Token), and co-author of ERC-7410. I am also a co-author of ERC-8203 (Agent Offchain Conditional Settlement), second of three, and wrote its reference implementation. That one is a draft still in EIP review. Not whitepapers that collect dust. Standards that run in production, handle real money, and survived the EIP (Ethereum Improvement Proposal) review process.
T-REX: Token for Regulated EXchanges
The institutional-grade security token standard. T-REX enables compliant issuance and management of security tokens with on-chain identity verification and transfer compliance. Used by Tokeny and adopted by institutions managing billions in tokenized assets.
The $32B+ adoption figure is theirs, not mine. Source: ERC3643 Association, erc3643.org, 2025. For the fractional-ownership side of the same problem, see ERC-6960, the dual-layer token standard, and for why these assets ended up wanting their own chain, read why RWA tokenization needs its own blockchain.
Dual Layer Token
A multi-asset token standard that combines fungible and non-fungible properties in a single contract. Built for real-world asset tokenization where a single asset (like a building) needs both divisible ownership shares and unique metadata per fraction.
ERC-20 Update Allowance By Spender
An ERC-20 extension that lets a spender reduce or revoke the allowance an owner granted to it. It adds one spender-side function and remains compatible with ERC-20.
Agent Offchain Conditional Settlement
A minimal interoperability framework that lets autonomous agents settle conditionally off-chain, using typed cryptographic structures and on-chain extension interfaces, without dictating the full channel implementation. Primary author Xianrui Qin. I built and contributed the reference implementation. Open draft, in EIP review.
Three different problems, three different standards. If you are splitting one real-world asset into tradable fractions without deploying a contract per slice, the answer is ERC-6960 and its dual-layer main-ID / sub-ID model. If your worry is an approved spender sitting on an allowance it no longer needs, the answer is ERC-7410, which lets the spender revoke its own allowance, without waiting for the owner to send a transaction. And if you are asking why regulated assets keep outgrowing general-purpose chains in the first place, that argument is laid out in why RWA tokenization needs its own blockchain.
