// ethereum standards

3 ERCs.
Peer-reviewed and shipped.

I co-authored three Ethereum token standards. Not whitepapers that collect dust. Standards that run in production, handle real money, and survived the EIP 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.

On-chain identity via ONCHAINID (ERC-734/735)
Transfer compliance rules engine
Adopted for $441M+ in tokenized securities
Used by Tokeny, now part of the Ripple ecosystem

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.

Single contract for fungible + non-fungible
Designed for RWA fractional ownership
Dual-layer: main asset + sub-tokens
Gas-efficient batch operations

ERC-20 Update Allowance By Spender

Fixes the broken approve() function in ERC-20. Instead of setting absolute allowances (which creates a race condition attack), ERC-7410 lets you safely increase or decrease allowances. Simpler, safer, fewer exploits.

Eliminates the approve() race condition
increaseAllowance / decreaseAllowance pattern
Backward compatible with ERC-20
Critical for AI agent spending limits
